Houttuynia Cordata Extract(30,000 Ppm)
Houttuynia cordata extract is derived from the herb Houttuynia cordata (Saururaceae), a flowering plant native to Southeast Asia with a long history of use in traditional Chinese medicine. Its main active components are polyphenolic flavonoids — including quercetin, quercitrin, hyperoside, and rutin — which exhibit anti-inflammatory, antioxidant, and antibacterial properties. The extract also contains polysaccharides composed of various sugar units that function as humectants. The flavonoid content can vary depending on whether the extract is taken from roots or leaves, and whether water or alcohol extraction is used.
The flavonoids in the extract provide antioxidant, anti-inflammatory, and antibacterial benefits, while quercitrin has been shown to help decrease UVB-induced skin damage. The polysaccharide fraction acts as a humectant, helping skin retain moisture. An in-vitro study also suggests the extract may have strong anti-allergic effects, potentially beneficial for conditions such as atopic dermatitis.
Flavonoid content and efficacy may vary significantly depending on the plant part (root vs. leaf) and extraction method (water vs. alcohol) used, which can affect consistency across formulations.
