Houttuynia cordata extract

Houttuynia cordata extract (CAS 164288-50-0), also sourced under the names Heartleaf Extract and Fish Mint Extract, is a botanical active derived from the Houttuynia cordata plant native to Southeast and East Asia.

It functions as a natural antimicrobial and antioxidant agent across cosmetic, nutraceutical, and pharmaceutical formulations. In personal care, it is incorporated into facial serums, toners, and acne-targeting treatments.

Natural preservation and skin-calming activity are required alongside synthetic or clean-label preservative systems. Pharmaceutical and healthcare product manufacturers use it in topical preparations and herbal remedy formulations.

These applications target antimicrobial efficacy in various medical contexts. In functional food and nutraceutical applications, it appears in botanical supplement blends and health beverages positioned around traditional herbal use.

Cosmetic formulators also value it as a supporting antioxidant in emulsions where oxidative stability of active ingredients is a formulation concern. The extract is available as a liquid, spray-dried powder, and paste.

Water, glycerin, or ethanol serve as common carrier systems for cosmetic-grade supply. Standard cosmetic and food-grade specifications are the primary commercial offerings for industrial buyers and manufacturers.

Buyers should confirm standardization parameters, such as total flavonoid or quercetin content, with suppliers. These specifications vary significantly across sources and depend on the specific extraction method used.
