Trichosanthes Kirilowii Root Extract

Trichosanthes kirilowii root extract (Tian Hua Fen) is derived from the starchy root of the Chinese snake gourd, used in TCM for its cooling and fluid-promoting properties. The cosmetic extract provides humectant moisture-binding and mild anti-inflammatory benefits from its polysaccharide and sterol fractions. Properly processed cosmetic extracts are not expected to retain biologically active trichosanthin.

humectantanti-inflammatorymoisturizingskin-conditioning
High polysaccharide content delivers strong humectant activity, drawing moisture into the skin and improving supplenessSterols and polysaccharide fractions exert anti-inflammatory effects, helping calm irritated or sensitized skinStarch-rich, emollient character contributes skin-conditioning and softening properties consistent with its traditional use as a skin treatment in TCM
The crude plant root contains trichosanthin, a ribosome-inactivating protein (RIP) with cytotoxic properties when injected — cosmetic-grade aqueous extracts undergo processing that effectively removes this protein; finished products are not expected to carry the RIP hazardPregnant individuals should avoid as a precaution given the plant's traditional associations, though topical exposure risk from a processed extract is negligible

Tuberose Polysaccharide
POLIANTHES TUBEROSA POLYSACCHARIDE

A polysaccharide derived from tuberose (Polianthes tuberosa). Functions as a humectant and film-former, providing intense moisturization and a silky skin feel. Used in premium Kanebo formulations.
