The Science
CurQD® is a botanical formulation composed of curcumin and Qing Dai (Indigo naturalis). Its development was informed by years of inquiry into plant-derived compounds and how they interact with the intestinal environment. Research groups across academic centers have examined this formulation through observational work, controlled trials, pediatric research, imaging-based evaluation, and combination-use studies.
