A multi-centered, randomized, double-blinded, placebo-controlled clinical trial to evaluate the safety of FoTv (a combination of two polypore mushrooms, Fomitopsis officinalis and Trametes versicolor) for COVID-positive outpatients with mild-to-moderate symptoms. Researchers used changes in 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.
