This product is a synergistic blend of hydro-ethanol extracts from Cumanda (Campsiandra angustifolia) bark and Houttuynia (Houttuynia cordata) leaf. It is designed to assist with comprehensive microbial support, with additional immune support and healthy inflammatory response support.* Our liquid extracts are made at our U.S. manufacturing facility using a specialized proprietary extraction process that optimizes the constituents of the herbs in their original, unprocessed state to obtain broad-spectrum concentration. Because our extracts are made in our own facility, we control all aspects of quality, including stringent ID testing, microbial testing, and heavy metal testing. NutraMedix rigorously follows current good manufacturing practices (cGMP), as do our suppliers.
