A B S T R A C T

Background

Chinese medicinal herbs are frequently used to treat the common cold in China. Until now, their efficacy has not been systematically

reviewed.

Objectives

To assess the effectiveness and safety of Chinese medicinal herbs for the common cold.

Search strategy

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2008, issue 2), which contains the

Cochrane Acute Respiratory Infections Group’s Specialised Register;MEDLINE (1966 toMay 2008); EMBASE (1980 toMay 2008);

AMED (1985 to May 2008); the Chinese Biomedical Database (CBMdisc) (1978 to May 2008); and China National Knowledge

Infrastructure (CNKI) (1994 to May 2008).

Selection criteria

Randomised controlled trials (RCTs) studying the efficacy of Chinese medicinal herb(s) for the treatment of the common cold.

Data collection and analysis

Four review authors telephoned the original trial authors of the RCTs identified by our searches to verify the randomisation procedure.

Two review authors extracted and analysed data from trials which met the inclusion criteria.

Main results

We found17 studies involving 3212 patients. Themethods of 15 studies were at high risk of bias. In only two studies was the risk of bias

low. Trials used “positive drugs”, of which the efficacy was not known, as controls. Different Chinese herbal preparations were tested in

nearly all trials. In only one trial was a Chinese herbal preparation tested twice. In seven trials, six herbal preparations were found to be

more effective at enhancing recovery than the control preparations. In the other 10 studies, seven herbal preparations were not shown

to be significantly different from the control. One study did not describe the difference between the intervention and control groups.

Authors’ conclusions

Chinese herbal medicines may shorten the symptomatic phase in patients with the common cold. However, the lack of trials of low

enough risk of bias, or using a placebo or a drug clearly identified as a control, means that we are uncertain enough to be unable to

recommend any kind of Chinese medicinal herbs for the common cold.

Chinese medicinal herbs to treat the common cold

The common cold is the most widespread acute respiratory tract illness affecting all age groups. Many Chinese herbal medicines are

used to treat this illness in China. Although we included 17 trials, involving 3212 patients, in this review, the risk of bias was so high that

the evidence did not support using any Chinese herbal preparation(s) for the common cold. Well-designed clinical trials are required.

B A C K G R O U N D

Description of the condition

sweat, generally have a high temperature, develop a thin, white fur

on the tongue, and experience a productive cough. ’Fever cold’,

on the other hand, is defined by the fact that patients do not feel

chilly, have an elevated temperature, develop a thin and slightly

yellow fur on the tongue, and experience a productive cough.

Herbs are indicated and dispensed in accordance with the symptoms

or causes of the cold. For example Shi Gao (Gypsum Fibrosum)

compounds can markedly abate fever (Deng 1998a),

and Chai Hu (Bupleurum chinesenes DC) and Jing Jie (Herba

Schizonepetae) act as analgesics (Wang 1998; Xu 1998). Ma

Huang (Herba Ephedrae) can be used to induce perspiration and

as an analgesic (Gong 1998); while Ban Xia (Rhizoma Pinelliae) is

dispensed to loosen sputumand suppress coughs (Xue 1998). Fang

Feng (Radix Saposhnikiviae) and Zhi Shu Ye (Folium Perillae) are

given for what is commonly termed ’chill cough’; Jin Ying Hua

(Flos Lonicerae) and Bo He (Herba Menthae) for ’fever cough’;

and Fructus Gardeniae for fever and convulsions.

Why it is important to do this review

Modern pharmacological experiments demonstrate that some

herbs, such as Jin Ying Hua (Flos Lonicerae) (Deng 1998b), Yu

Xin Chao (Herba Houttuyniae) (Deng 1998c), and Ban Lan Gen

(Radix Isatidis) (Deng 1998d) do have antiviral or antibacterial

functions. The principles of traditional Chinese medicine (TCM)

state that the ideal effect will result from using Chinese medicinal

herbs according to its guidelines. Using the herbs incorrectly may

cause harm rather than benefit; for example, the herbs for ’fever

cold’ should never be used for a ’chills cold’.

In China, more than 100 varieties of herbal preparation are used

in the prevention and treatment of the common cold. Hundreds

of millions of dollars are spent on treating colds each year (Zuo

2006). Hundreds of clinical studies have been carried out on Chinese

medicinal herbs for the common cold. These include five

randomised controlled trials (RCTs) involving 880 participants

conducted on “Huang Zhi Hua oral preparation” (Cheng 1999;

He 1999; Pan 1999; Wang 1999a; Yi 1999a). Almost all of these

studies have reported a positive effect.

In high-income countries there is increasing public interest in,

and use of, a wide range of therapies which lie outside the ’mainstream’

or traditionalWesternmedical practice. The recentHouse

of Lords Select Committee report on Complementary and Alternative

Medicine (CAM) heard that “we are now experiencing a

rapid increase in the use of CAM across the Western World” (

HLSC 2000). Whether we support or criticise their effectiveness,

herbal medicines are widely used.

There is evidence to indicate that not all herbs are risk-free. There

are concerns about adverse events, including allergic reactions and

Chinese herbal nephropathy (CHN) (Lampert 2002; Lord 2001;

Nortier 2000). Scientific evidence which indicates that Chinese

herbal medicines are more effective than antibiotics in the treatment

of acute respiratory infections is insufficient (Liu 1998).

O B J E C T I V E S

To assess the efficacy and safety of Chinese medicinal herbs for the

treatment of the common cold in children and adults.

Secondary objectives were to compare the efficacy of different

Chinese medicinal herbs and record any related adverse events.

When making comparisons between groups intended for treatment

with Chinese medicinal herbs and groups allocated to the

placebo or other current treatment regimes, or various Chinese

medicinal herbs, we tested the following hypotheses:

1. that there is no difference in the number of people cured

by the end of the third day; and

2. that there is no difference in the number of adverse

events.

M E T H O D S

Criteria for considering studies for this review

Types of studies

Randomised controlled trials (RCTs) studying the efficacy of Chinese

medicinal herbs for the common cold. If trials did not report

the outcome we were looking for, we contacted the trial authors

to ask for this additional information; the trials were excluded if

this information was not available.

Types of participants

Children (17 years or younger) and adults (18 years or older) with

the common cold.

The common cold is defined as acute inflammation of the nasal

cavity, pharynx or larynx, caused by viral infection(s). Typical

symptoms include runny nose, nasal congestion, sneezing, sore or

scratchy throat, cough, fatigue and fever. Ideally, the diagnostic

criteria for the common cold should be described in the trial. To

allow for changes in classification and diagnostic criteria of the disease,

the diagnosis should be established using the standard criteria

valid at the time of conducting the trial. Changes in diagnostic

criteriamay have produced variability in the clinical characteristics

of the patients included and the results obtained. We considered,

documented and explored these changes in a sensitivity analysis.

We excluded colds caused by influenza in this review - symptoms

always included headache, muscle ache and fatigue, high fever,

usually a cough, sometimes a runny nose, sneezing, sore throat,

and itching eyes, nose, or throat.We also excluded acute bronchitis

developing froma case of common cold.These illnesses are assessed

in other Cochrane Reviews (Chen 2005; Wei 2005).

Chinese medicinal herbs for the common cold (Review) 3

Copyright 2009 The Cochrane Collaboration. Published by JohnWiley & Sons, Ltd.

We excluded patients concurrently suffering fromother infectious

or febrile diseases, or both.

Types of interventions

Chinese herbal medicines compared with placebo or other treatments

for the common cold.We excluded prohibited or suspended

Chinese herbal preparations.

Types of outcome measures

Primary outcomes

Recovery refers to whether the symptoms of common cold were

cleared within three days after treatment. Trials use the following

outcome measures:

1. ’fast effect’ - which means that the fever abated within

two to four hours after treatment, with symptoms subsiding

after 24 hours. This was considered as a ’recovery’;

2. ’marked effect’ - which means that the fever abated

within 24 to 48 hours after treatment, with symptoms

of the common cold subsiding after 48 hours. This was

also considered as a ’recovery’.

Secondary outcomes

1. Fever clearance time: fever clearance time refers to the

time between commencing treatment and temperature

returning to normal.

2. Improvement: temperature returns to normal and most

of the symptoms disappear within three days of administration

of the Chinese herbal preparation.

3. Partial improvement: fever abatement and some symptoms

disappear within three days of administration of

the Chinese herbal preparation.

4. No improvement: no significant change in symptoms

was noted at the end of the third day following the administration

of theChinese herbal preparation. Patients

with a high fever treated with physiotherapy or antibiotics

(for clearance of fever during the treatment) were

considered in this category.

5. Adverse events: we defined serious adverse events according

to the ICHGuidelines (ICHEWG1997) as any

event that leads to death, is life-threatening, requires inpatient

hospitalisation or prolongation of existing hospitalisation,

results in persistent or significant disability,

and any important medical event whichmay have jeopardised

the patient or required intervention to prevent

it. We considered all other adverse events to be nonserious.

6. Additional outcomes: we attempted to analyse the effects

of the interventions on TCM signs, which follow

a particular theoretical and methodological pathway, as

additional outcomes in this review. See the final point in

the Discussion section with regards to validating methods

used to measure TCM signs.

Data collection and analysis

Selection of studies

Six review authors (WT, ZX, ZJ, XLX, QY, LG) performed the

searches and retrieved articles. The same review authors selected

the trials to be included in the study and no disagreements were

recorded.We retrieved the selected trials which claimed to be randomised.

We then confirmed that they were correctly randomised

by telephoning the original trial authors.

Data extraction and management

Two review authors (WT, LG) independently extracted data using

a piloted data extraction form.We extracted data on study characteristics

including methods, participants, interventions and outcomes.

There were no disagreements. The formulation contents of

included studies and herb names in three languages are described

in Table 1 and Table 2.

We performed an intention-to-treat (ITT) analysis on three trials

(Chang 2005; Chang 2007; Wang 2008a). We performed perprotocol

analyses on the other studies. We reported the number

lost to follow up in the notes column of the ’Characteristics of

included studies’ table.

Assessment of risk of bias in included studies

We assessed the risk of bias of each trial in terms of generation

of allocation sequence, allocation concealment, blinding, uncompleted

data and selective reporting; and classified themas ’lowrisk’,

’moderate risk’, or ’high risk’ according to the guidelines of the

Cochrane Handbook for Systematic Reviews of Interventions 5.0.0 (

Higgins 2008) and as described in Wu 2007a. There was no disagreement

in this process.

Sequence generation

An adequate approach for generating allocation sequence with a

low risk of selection bias should be by using a random numbers table

or computer software, or other simple randomisationmethods,

for example, coin tossing or card shuffling. We considered a trial

which only mentions ’random’ but does not include a description

of the approach used as a moderate risk of selection bias.

Allocation sequence concealment

Low risk of selection bias: adequate measures to conceal allocation

sequence is defined as the person who generates an allocation

sequence not recruiting the participants, for example, by central

randomisation. Examples of concealing allocation sequences are

using sealed opaque envelopes or storing allocation sequences in

a locked computer.

Moderate risk of selection bias: where concealment of the allocation

sequence is mentioned but the approach used is not reported.

Chinese medicinal herbs for the common cold (Review) 8

家园 9

High risk of selection bias: allocation concealment is reported

inadequately, or is not performed at all.

Level of blinding

Masking of both the participants and results assessor was considered

as a low risk of performance or/and detection bias.

Single blinding of the results assessor was considered as amoderate

risk of performance or/and detection bias. If single blinding was

performed on the participants but not the results assessor, it was

considered as a high risk of detection bias.

Non-blinding for detection of outcomes includes quality of life

(QoL); adverse events were considered as a high risk of detection

bias. Blinding was not considered necessary for reporting mortality.

Incomplete outcome data: assessment for potential bias of

exclusions and attrition

Low risk of bias: trials where few exclusions and attrition are noted

and an intention-to-treat (ITT) analysis is possible.

Moderate risk of bias: trials which report the rate of exclusions

or/and attrition to be about 10%, whatever ITT analysis is used.

High risk of bias: the rate of exclusion or/and attrition is higher

than 15%, or there are wide differences in exclusions between

groups, whatever ITT analysis is used.

Measures of treatment effect

We analysed the data using Review Manager 5 (RevMan 2008).

We compared outcome measures for binary data using risk ratios.

For continuous data, we used the mean difference.We conducted

a pooled analysis for two trials only (Chang 2002; Yu 2005).

Assessment of heterogeneity

We assessed heterogeneity by using the Chi2 test with a 10% level

of statistical significance and by using the I2 statistic to estimate

the total variation across studies that was due to heterogeneity

rather than chance. Less than 25% was considered as low level

heterogeneity; 25% to 50% was considered as a moderate level;

and higher than 50% as a high level of heterogeneity (Higgins

2002).

Assessment of reporting biases

No - low risk of reporting bias: all outcomes are reported in detail.

Probably yes - moderate risk of reporting bias: at least one of the

outcomes are mentioned, but not in detail.

Yes - high risk of reporting bias: at least one of the outcomes are

not reported.

Data synthesis

We used the random-effectsmodel for a pooled analysis of the two

studies (Chang 2002; Yu 2005) as most of the studies had a high

level of heterogeneity. We did not perform a pooled analysis for

the other trials due to unknown formulations used in these trials.

We listed non-randomised controlled studies and the reasons of

exclusion in the ’Characteristics of excluded studies’ table, but did

not discuss them further.

R E S U L T S

Description of studies

See:Characteristics of included studies;Characteristics of excluded

studies; Characteristics of studies awaiting classification.

Results of the search

A total of 430 trials that claimed to be randomised were retrieved.

We successfully contacted 365 trial authors by telephone.Of these

trials, 302 were excluded, either because the trial authors misunderstood

true random allocation or the trial reports were multiple

versions of same study (see the ’Characteristics of excluded studies’

table), of those, 67 were additional studies later excluded in this

updated version of review.

One hundred and nine are listed in the ’Studies awaiting classification’

section. One of these studies, for example, assessed an

intervention containing ’Yuxincao’, a drug which the State Food

and Drug Administration (SFDA) stopped production of, due to

unclear adverse events. Other trials are allocated to this section

as we could not locate the original trial authors to identify the

randomisation method.

Seventeen studies were identified as true RCTs and fulfilled our

inclusion criteria (Chang 2002; Chang 2005; Chang 2007; Chen

2004; Li 1998; Li 1999a; Liu 2002; Ma 2000; Pan 2000; Song

2004a; Wang 1998; Wang 2004; Wang 2008a; Yang 2000; Yu

1997; Yu 2005; Zhang 2008), of those, three (Chang 2007;Wang

2008a; Zhang 2008) were additional trials later included in this

updated version of review.

Included studies

All 17 included trials used a parallel group design. Four trials (

Chang 2007; Li 1999a; Wang 2008a; Zhang 2008) were multicentre

trials.

A total of 3212 participants were included in the 17 trials, with

numbers of participants in each trial varying from58 to 463. Only

three trials (Chang 2005; Chang 2007; Wang 2008a) mentioned

that the sample size was calculated according to the SFDA’s regulation

about sample size of non-inferiority test studies (that a total

number of 200 participants be included); extra participants were

also included in these trials to avoid possible attrition bias.

Nine trials included children aged from six months to 14 years (

Chen 2004; Li 1998; Liu 2002;Ma 2000; Pan 2000; Song 2004a;

Wang 1998; Yang 2000; Yu 1997). Eight trials included adults

aged from 18 to 65 or 72 years old (Chang 2002; Chang 2005;

Chang 2007; Li 1999a;Wang 2004;Wang 2008a; Yu 2005;Zhang

2008).

Eleven trials included participants according to TCM signs. Nine

trials (Chang 2005; Chang 2007; Chen 2004; Li 1998; Li 1999a;

Ma 2000; Wang 2008a; Yang 2000; Zhang 2008) included patients

with “fever cold”. One trial (Yu 1997) included both “fever

cold” and “chills cold” patients. Three trials (Chang 2002; Wang

2004; Yu 2005) included “chills cold”.Two trials (Pan 2000;Wang

1998) did not sort the patients by TCM signs.

Two trials (Chang 2002; Yu 2005) compared the Chinese herbs

Sanhan Jiere Koufuye and (Fenghan) Biaoshi Ganmao Chongji.

Other trials used different interventions and comparators. These

are listed below:

Yu 1997 comparedCaichenQinreWeixinGuanchangji

with virazole and acetaminophen.

Li 1998 compared Qinwen Keli granule with Kangbingdu

Koufuye.

Wang 1998 compared JianerQinjie YewithQinre Jiedu

Li 1999a compared Qinkailing injection with Lincomycine.

Ma 2000 compared Shuanghua Penhuji with

Shuanghuanglian Qiwuji.

Pan 2000 compared Xiaoer Reganning with Vitamin C

Yinqiao Chongji.

Yang 2000 compared Huanghu Jiere Daipaoji with

Shiqi Ganmao Daipaoji.

Liu 2002 compared Kangbingdupian with Banlangen

Chongji.

Chen 2004 comparedGegenCenlianweiWanwith Yinqiao

Jiedupian.

Song 2004a compared self-prepared TCM cream with

penicillin or lincomycin.

Wang 2004 compared Sufeng Ganmao Koufuye with

Ganmao Qinre Koufuye.

Chang 2005 compared Jinlian Qinre capsules with Jinlian

Qinre granules; that is the same ingredients in two

different forms. The principle of selecting the control

drug was that its “effect was commonly recognised”. A

double-dummy placebo was used in both arms.

Chang 2007 compared ChaigeQingre granule with Fufang

Shuanghua granule.

Wang 2008a used a double-dummy placebo in both

arms, and compared Yiqing Shuangjie granule and

Chaihuang tablet placebo with Chaihuang tablet, and

compared Yiqing Shuangjie tablet and Caihuang tablet

placebo with Chaihuang tablet.

Zhang 2008 comparedQingyin injectionwithQinkailing

injection

Recovery (expressed as a dichotomous event)was used as a primary

outcome in all trials, except for Pan 2000 and Zhang 2008. Inefficacy

was reported in 15 trials. Fever clearance time was reported in

six trials (Chang 2002; Chang 2005; Li 1998;Wang 1998;Wang

2008a; Yu 1997). The time point at which the temperature started

to abate was reported in four trials (Chang 2005; Li 1998; Wang

1998; Wang 2008a). Six trials (Chang 2002; Chang 2005; Chen

2004; Li 1999a;Wang 2008a; Yu 1997) compared the prevalence

of viral respiratory tract infection by a throat swab culture. Five

trials reported that liver and kidney function tests were carried

out to look for side effects or adverse events (Chang 2002; Chang

2005; Chang 2007; Wang 2008a; Zhang 2008).

Eight trials (Chang 2002; Chang 2005; Chang 2007; Chen

2004; Song 2004a;Wang 2004;Wang 2008a; Yu 2005) evaluated

changes of TCM signs, which included “e feng han” (fear of wind

and cold); “fa re” (fever); “bi sai liu ti” (snuffles and runny nose);

examination of the colour and surface of the tongue; and “mai

methods of double blinding. Other trials did not mention how

they used blinding.

Follow up and exclusions

Assessment for potential bias exclusions and attrition

Six trials (Chang 2002; Chang 2005; Chang 2007; Wang 2004;

Wang 2008a; Zhang 2008) reported a loss of participants for the

above listed reasons.Three trials (Chang 2005;Chang 2007;Wang

2008a) used both ITT and per-protocol analysis, and two trials (

Chang 2002; Wang 2004) used per-protocol analysis only.

Selective reporting

Assessment for reporting bias

Selective reporting was not identified in the trials.

Effects of interventions

We performed a pooling analysis on two trials only (Chang 2002;

Yu 2005) due to heterogeneity in the interventions and controls.

1. Recovery

Trials showing statistically significant differences between

the intervention and comparison

Six trials reported that the intervention group had a statistically

significant better recovery than the control group. Of these, three

studied children (Li 1998; Ma 2000; Song 2004a) and the other

three studied adults (Li 1999a; Wang 2004; Wang 2008a) with

the common cold. The results are shown below:

1. Qinwen Keli granule was more effective than Kangbingdu

Koufuye (risk ratio (RR) 2.19, 95% confidence

interval (CI) 1.61 to 2.96) (Li 1998);

2. Shuanghua Penhuji was more effective

than Shuanghuanglian Qiwuji (RR 1.48, 95% CI 1.11

to 1.97) (Ma 2000);

3. TCM cream was more effective than penicillin (RR

2.10, 95% CI 1.20 to 3.67) (Song 2004a);

4. Sufeng Ganmao Koufuye was more effective than Ganmao

Qinre Koufuye (RR 1.43, 95% CI 1.02 to 1.99) (

Wang 2004);

5. Qinkailing injection was more effective than lincomycin

in three doses, respectively (120 ml/day RR

1.41, 95% CI 1.07 to 1.86; 160 ml/day RR 1.41, 95%

CI 1.08 to 1.86; and 200 ml RR 1.52, 95% CI 1.15 to

2.00) (Li 1999a);

6. YiQing ShuanJie capsule and YiQing ShuanJie tablet

was more effective than Chaihuang tablet respectively

(YiQing ShuanJie capsule RR 1.59, 95% CI 1.08 to

2.33, and YiQing ShuanJie tablet RR 1.67, 95% CI

1.14 to 2.43) (Wang 2008a).

Trials showing no statistically significant differences between

the intervention and comparison

Another eight trials showed no statistically significant differences

in duration of symptoms between the intervention and control

groups. Of these, four studied adults (Chang 2002; Chang 2005;

Chang 2007; Yu 2005) and the others studied children (Chen

2004; Wang 1998; Yang 2000; Yu 1997).

1. Jinlian Qinre capsule versus Jinlian Qinre granule (RR

0.97, 95% CI 0.58 to 1.62) (Chang 2005);

2. Sanhan Jiere Koufuye versus (Fenghan) Biaoshi Ganmao

Chongji (combined RR 1.51, 95% CI 0.79 to

2.90) (Chang 2002; Yu 2005). A sensitivity analysis was

performed by deselecting the study by Yu 2005 which

had been conducted in same hospital as the preparation

provider showed that it had a similar result (RR 1.20,

95% CI 0.85 to 1.69);

3. Gegen Cenlianwei Wan versus Yinqiao Jiedupian (RR

1.17, 95% CI 0.80 to 1.73) (Chen 2004);

4. Jianer Qinjieye versus Qinre Jiedu Koufuye (RR 1.45,

95% CI 0.99 to 2.13) (Wang 1998);

5. Huanghu Jiere Daipaoji versus Shiqi Ganmao Daipaoji

(RR 3.62, 95% CI 0.88 to 14.91) (Yang 2000);

6. Caichen Qinre Weixin Guanchangji with virazole and

acetaminophen (RR 1.40, 95% CI 0.71 to 2.74) (Yu

1997).

7. A phase II and phase III trial by the same study

team compared Chaige Qingre granule versus Fufang

Shuanghua capsule, respectively. The combined results

of these two studies showed there was no statistically

significant difference between the two drugs (RR 1.05,

95% CI 0.75 to 1.48) (Chang 2007).

2. Improvement

The Pan 2000 study showed a statistically significant improvement

in the severity of symptoms when using the intervention

Xiaoer Reganning, compared to vitamin C (Yinqiao Chongji), for

children with the common cold (RR 1.69, 95% CI 1.22 to 2.35).

In this trial, the definition of ’improvement’ included both shortening

of the duration of symptoms and lessening of the severity

of symptoms. The other 14 trials and two combined trials showed

no differences between the two groups on lessening of severity of

symptoms.

Seven trials showed that the number of inefficacies in the intervention

group was statistically significantly less than the control

group. Of these, one trial (Wang 2004) included adults and the

other trials included children:

5. Sufeng Ganmao Koufuye was more effective than Ganmao

Qinre Koufuye (RR 0.16, 95% CI 0.07 to 0.38) (

Wang 2004);

6. Huanghu Jiere Daipaoji was more effective than Shiqi

Ganmao Daipaoji (RR 0.10, 95% CI 0.01 to 0.85) (

Yang 2000).

7. The Yiqing Shuanjie capsule and Yiqing Shuanjie tablet

have a similar effect toChaihuang tablet (RR 0.94, 95%

CI 0.71 to 1.25, and RR 0.91, 95% CI 0.68 to 1.21,

respectively) (Wang 2008a).

3. Partial improvement

Five trials showed that partial improvement in the intervention

group was statistically higher than the control group.Of these, one

trial (Wang 2004) included adults and the remaining four trials

included children with the common cold.

1. Qinwen Keli granule was more effective than Kangbingdu

Koufuye (RR 1.05, 95% CI 1.00 to 1.11) (Li

1998);

2. Xiaoer Reganning was more effective than vitamin C

Yinqiao Chongji (RR 1.24, 95% CI 1.02 to 1.50) (Pan

2000);

3. Jianer Qinjieye was more effective than Qinre Jiedu

Koufuye (RR1.32, 95%CI 1.05 to 1.65) (Wang 1998);

4. Sufeng Ganmao Koufuye was more effective than Ganmao

Qinre Koufuye (RR 1.37, 95% CI 1.17 to 1.60) (

Wang 2004).

Seven trials and a combined analysis of two trials and showed

no statistically significant differences between the two groups. Of

these, three trials included adults (Chang 2002; Chang 2005; Yu

2005) and the other five trials included children with the common

cold.

1. Sanhan Jiere Koufuye versus (Fenghan) Biaoshi Ganmao

Chongji (combined RR 1.04 95% CI 0.92 to

1.16) (Chang 2002; Yu 2005). A sensitivity analysis was

performed by deselecting the trial by Yu 2005 which

was conducted in the same hospital as the preparation

provider, and had a same result (RR 1.01, 95% CI 0.94

to 1.09).

2. Jinlian Qinre capsules had the same efficacy as Jinlian

Qinre granules (RR 1.00, 95%CI 0.95 to 1.06) (Chang

2005);

3. Gegen Cenlianwei Wan had the same efficacy as Yinqiao

Jiedupian (RR 1.17, 95% CI 0.96 to 1.43) (Chen

2004);

4. Shuanghua Penhuji had the same efficacy as

Shuanghuanglian Qiwuji (RR 1.05, 95% CI 0.99 to

1.12) (Ma 2000);

5. Huanghu Jiere Daipaoji had the same efficacy as Shiqi

Ganmao Daipaoji (RR 1.15, 95% CI 0.98 to 1.35) (

Yang 2000);

6. Caichen Qinre Weixin Guanchangji had the same efficacy

as virazole and acetaminophen (RR 1.13, 95% CI

0.91 to 1.39) (Yu 1997).

4. No improvement

Nine trials showed no statistically significant differences in outcomes

between the intervention and control groups. Of these,

three trials (Chang 2007; Chang 2005; Li 1999a) included adults

and the other trials included children.

1. Sanhan Jiere Koufuye had the same efficacy as (Fenghan)

Biaoshi Ganmao Chongji (combined RR 0.49,

95% CI 0.14 to 1.73) (Chang 2002; Yu 2005). A sensitivity

analysiswas performed by deselecting the Yu 2005

trial, which had been conducted in the same hospital

as the preparation provider and showed a similar result

(RR 0.67, 95% CI 0.06 to 7.09).

2. Chaige Qingre granule had the same efficacy as Fufang

Shuanghua capsule in the phase II (RR 2.00, 95% CI

Shuanghua capsule in the phase III (RR 1.07, 95% CI

0.23 to 4.97) (Chang 2007);

4. Jinlian Qinre capsule had the same efficacy as Jinlian

Qinre granule (RR 0.69, 95%CI 0.23 to

家园 13

5. Duration of fever

Five trials reported no difference in the duration of fever between

the intervention and control groups. Two of these trials reported

no difference in the number of participants whose temperatures

were normalised within 24 hours (Chang 2002), 48 hours and 72

hours (Yu 1997): Sanhan Jiere Koufuye versus (Fenghan) Biaoshi

Ganmao Chongji (RR 1.02 95% CI 0.85 to 1.22) (Chang 2002);

and Caichen Qinre Weixin Guanchangji versus virazole and acetaminophen

(RR 1.46, 95% CI 0.89 to 2.40, and RR 0.33, 95%

CI 0.11 to 0.99, respectively) (Yu 1997).

Likewise, another three trials (Chang 2002; Chang 2005; Wang

2008a) showed no difference in duration of fever between the two

groups (WMD -0.29 hours, 95% CI -2.26 to 1.68, WMD -3.91

hours, 95%CI -8.24 to 0.42,WMD 4.20 hours, 95%CI -1.41 to

9.81 and WMD 3.62 hours, 95% CI -2.74 to 9.98, respectively).

Three trials (Chang 2005; Li 1998; Wang 1998) reported a statistically

significantly shorter duration of fever in the treatment

group compared to the control group 2.02, 6.90 and 5.70 hours,

respectively (WMD -2.02, 95% CI -3.86 to -0.18; WMD -6.90,

95% CI -9.94 to -3.86, and WMD -5.70, 95% CI -10.09 to -

1.31, respectively). One study (Li 1998) showed that in the treatment

group the average duration of fever was longer than control

group by 11.60 hours (WMD -11.60, 95% CI -15.65 to -7.55).

Another trial (Wang 2008a) showed no statistically significant differences

in the time to resolution of fever in the treatment group

A and B as compared to the control group (WMD -2.06 hours,

95% CI -5.02 to 0.90, and WMD -1.44 hours, 95% CI -4.70 to

1.82).

6. Adverse events

None of the trials reported any adverse events, according to our

definitions.

7. Additional outcomes

Seven trials (Chang 2002; Chang 2005; Chang 2007; Chen 2004;

Wang 2004; Wang 2008a; Yu 2005) reported effects on TCM

signs. We only analysed data in two studies (Chang 2005; Chen

2004). There were no statistically significant differences between

the two groups in these trials.

Summary of main results

Studies of Chinese herbal medicines for the common cold lack

sufficient power to provide reliable estimates of their efficacy, due

to poor study design and methodological quality.

Although Chinese herbal medicines as a treatment for the common

cold and the methods of manufacturing these medicines are

widely accepted in China, most of the constituents of the pharmacologically

prepared drugs used in trials cannot be specified.

This is in marked contrast to the pharmacological agents used

in Western medicine, for which the chemical constituents, their

quantities and the percentage of any impurities or contaminants

are precisely known. In addition, the variation between different

production batches of Western medicines is kept within specified

limits. In contrast, variation between formulations and batches

of pharmacological agents are inevitable in traditional Chinese

medicine (TCM), although the Chinese Government specifies the

acceptable limits of variation. This variation is a factor that may

contribute to any heterogeneity between different study results.

A large number of the trials initially identified claimed to be randomised

controlled trials (RCTs). However, after contacting the

trial authors to request information regarding the method of randomisation

used, we found that more than 95% of the authors

misunderstood the concept of randomisation. In addition to this,

some of the studies were conducted several years ago, and the trial

authors may have forgotten the details of the methodology they

employed. This could lead to a memory bias and undermine the

veracity of information.

Some studies (Chang 2002; Li 1998; Li 1999a; Ma 2000; Wang

2004; Yang 2000; Yu 1997) used unequal arms in their design.

Of these studies, Yu 1997 used a proportion of 3:1, and only 15

patients were included in the control group (43:15). However,

consideration of the sample sizes was not reported in these trials,

which makes it difficult to detect the differences between the two

groups accurately. This may lead to a low test power.

Finally, we considered it pertinent to attempt to compare selected

TCMsigns in different groups of participants. TCMsigns are difficult

to quantify because they use subjective outcomes. For example,

’wu han’ means that the participant feels cold whilst also

having a fever, and this can be divided into low, medium and high

categories, depending on the participants’ subjective view. ’Mai xiang’measures

the pulse; in TCMit is a complex and difficult technique

to judge this accurately and often dependent upon on the

physician’s experience.TCMresearchers and physicians should decide

upon an accurate and consistent method of measuring TCM

signs.

Quality of the evidence

None of the trials included in this review used a placebo as a control:

instead “positive effect drugs” were selected. Two studies (

Chang 2005; Chang 2007) mentioned that the rule of selecting

the control drug was that “the effect was generally acknowledged”.

This may result in false positive findings, as a number of interventions

are considered effective for the common cold, particularly if

trial conductors know that a “positive” drug was used in the trial

and the purpose of the study was to demonstrate the same effect

as the control (so called “equal effect test”). For example, Chang

2005 compared two different forms of the same ingredient. In this

case, “double blinding” would not be a valid term. This may result

in false positive findings: if the trialist knows that a “positive” drug

was used and the study was an “equal effect test” study, there is

a potential risk that the outcome detectors will give same results

for the two groups. For example, the purpose of Chang 2005 was

to compare two different forms of the same drug; one was in a

granule form and the other was in a capsule form and the trialists

were aware of this. Therefore, there was a possibility that the

results were not scrutinised carefully - particularly the subjective

outcomes. In this case “double blinding” does not have any value.

We found that three trials claimed to have used ’double blinding’ (

Chang 2005; Chang 2007; Yang 2000) and one used ’single blinding’

(Chen 2004). These studies found a similar recovery rate as

the “positive” control. Two of the ’double blinding’ studies (Wang

2004; Wang 2008a) found the recovery rate in the intervention

group to be higher than the control group by almost 50% (Wang

2004 RR 1.43; Wang 2008a RR 1.59 and RR 1.67). However,

Wang 2004 lacked a description of how to verify the success of the

blinding. Another trial (Pan 2000) found the marked improvement

rate in the intervention group to be higher than the control

group (RR 1.69). For a disease like the common cold, which can

go into spontaneous remission within one week, it is very difficult

to find that the effect of a new drug is better than the “positive

effect” of the control drugs.We have to point out that the possible

reason that the relative risk is so high is that a high risk of selection

bias, detection bias or both may have existed in the studies where

the effects were similar or higher than “positive effect” controls.

Many trials incorrectly used drugs whose effects have not been

demonstrated as a control. Thus it is difficult to determine the

efficacy of the intervention by comparison.Where the intervention

is equal in efficacy to the control, no conclusion can be made.

For example, the average rate of recovery from the common cold

was the same for those participants taking Jinlian Qinre capsules

(intervention) and JinlianQinre granules (control) (Chang 2005).

Since there is no evidence assessing the efficacy of Jinlian Qinre

granules, we therefore cannot determine the efficacy of Jinlian

Qinre capsules.

Potential biases in the review process

We found the formulations of interventions in five studies (Ma

2000; Pan 2000; Yang 2000; Yu 1997; Yu 2005) were prepared

by either the trial authors or colleagues in their ho
