Banxie Xiexin Decoction (BXD)Study Participants
88The study aims to evaluate the efficacy of a modified Banxia Xiexin Decoction (BXD) for Wei-Pi through a randomized, waitlist controlled trial.
After being informed about the study plan, potential risk and benefits, all subjects will give written informed consent prior to participation and undergo eligibility screening. Eligible participants will be randomized, in a 1:1 ratio, into BXD group and waitlist group.
A modified Banxie Xiexin Decoction based on Chinese medicine syndrome differentiation.
Participants will be diagnosed and treated by Chinese medicine practitioners (CMPs) with at least 5 years of clinical experience. CMPs will differentiate syndrome and prescript herbs in a semi-standardized protocol, which consists of a base Chinese medicine decoction, Banxia Xiexin Decoction (BXD), and the additional syndrome-specific herbs. The modified decoction will be prepared in a conventional decocting method at the Chinese medicine pharmacy in the clinic (HKBA-HKU CMCTR) and will be packaged into bags by the auto-decocting machines. Participants will take the decoction twice per day, 5 days per week, for 3 weeks.
Participants in the waiting list control group will be observed for a three-week waiting period. Rescue medication is not restricted.
