A multi-centered, randomized, double-blinded, placebo-controlled clinical trial evaluated the safety of mQFPD as a modified form of Qing Fei Pai Du Tang (a Chinese herbal formula that has widely been used in Asia for COVID-positive outpatients with mild-to-moderate symptoms). Researchers used COVID-19 viral load, blood markers, and a 14-day symptom diary to examine the safety, feasibility, and preliminary effects of the study product versus placebo.
