Objective To observe the therapeutic effect of Qingjin Kangdu Beverage [ antitoxic beverage of Qinghao （ Herba Artemisiae Annuae ） and Jinyinhua （ Flos Lonicerae Japonicae ）] on viral myocarditis （ VM ） .Methods Eighty patients with VM were randomized into treatment group and control group

with 40in each.The control group was given conventional thera- py and the treatment group was added with self-made Qingjin Kangdu Beverage.One treatment course lasted for 4weeks.The heart rate （ HR ）

cardiac output （ CO ）

stroke volume （ SV ）

ejection fraction （ EF ）

cardiac index （ CI ）

the efficacy of elec- trocardiogram （ ECG ）

lactate dehydrogenase （ LDH ）

creatine kinase （ CK ）

creatine kinase isoenzyme （ CK-MB ） and clinical efficacy were observed.Results The total effective rate of the treatment group and the control group was 92.50% and 80.00%

respectively.There was significant difference in the therapeutic efficacy between groups （ P<0.05 ） .The total effec- tive rate of ECG efficacy of the treatment group and the control group was 92.50%and 85.00%

respectively.There was sig- nificant difference in the ECG efficacy between groups （ P<0.05 ） .The CO

SV

CI

EF

HR

LDH

CK and CK-MB signifi- cantly improved in both groups after treatment （ P<0.05 ）

especially in the treatment group （ P<0.05 ） .Conclusion Qingjin Kangdu Beverage is effective for VM.
