1. Neither the duration nor severity of symptoms of upper respiratory tract infection was reduced after Traditional Chinese medicine treatment with either Jing Fan Bai Du san or Ying Qiao san.
2. For patients with wind-cold syndrome, Jing Fan Bai Du san might be able to improve general health more than placebo.
3. Both Jing Fan Bai Du san and Ying Qiao san were well tolerated, with no excess in the incidence of side effects compared to placebo.
4. Randomised double-blind placebo-controlled trials are objective methodology to determine the effectiveness and side effects of Chinese herbal medicines.
