Psyllium husk has been harvested across India and the Mediterranean basin for centuries, prized in both Ayurvedic practice and traditional European herbalism as one of the oldest known dietary fiber sources. Cascara sagrada, "sacred bark" in Spanish, was a trusted remedy among Native American healers of the Pacific Northwest well before it ever showed up in a formula like this one. Licorice root carries a documented history stretching back through Chinese, Egyptian, and Greek herbal traditions alike, and kelp has been a staple of coastal Asian diets for generations, simply food, eaten daily, centuries before "supplement" was even a word. Red clover rounds out the formula, drawn from a long tradition of European and Native American herbal use.
