About this trial

The goal of this study is to learn whether Gou-Teng-San (GTS), a traditional herbal medicine, is effective and safe for adults with episodic migraine. In this double-blind randomized controlled trial, participants with episodic migraine will be assigned by chance to a study treatment group. The study will evaluate whether GTS can reduce migraine frequency, improve migraine-related symptoms, and lessen the impact of migraine on daily life. Researchers will also monitor safety and tolerability throughout the study.
