摘要

BackgroundAlthough China has a long history of using acupoints herbal patching (acupoints herbal patching means applying herbal patch on special acupoints to stimulate skin to form blisters, hyperemia, and even suppuration) in Sanfu Days (Sanfu Days are supposed to be the three hottest days in a year which is calculated by the ancient calendar) for the treatment of asthma, there is insufficient evidence to support its effectiveness and safety issues. This study investigated the efficacy and safety of acupoints herbal patching compared with placebo in participants with asthma in clinical remission stage.
