What this Trial Is About
Researchers are evaluating whether Gou-Teng-San GTS, a traditional herbal medicine, is effective and safe for adults with episodic migraine. This Phase 3 double-blind randomized controlled trial aims to see if GTS can reduce the number of migraine days, improve migraine symptoms, and lessen the impact of migraines on daily life. Safety and tolerability will be monitored throughout the study period. Participants will be randomly assigned to receive either Gou-Teng-San or a placebo starch, both given orally at a dose of 5 grams twice daily, once in the morning and once in the evening, for 4 consecutive weeks. The study includes a screening period followed by the 4-week treatment phase. During the study, participants will track their migraines using a headache diary and undergo assessments to measure changes in migraine frequency from baseline to the fourth week. Researchers will also monitor safety, tolerability, and participant compliance. The primary outcome is the change in the average number of migraine days per month after 4 weeks of treatment.
