About

Stemona root powder, a traditional herbal ingredient used in East Asian skincare for its soothing and protective skin properties.

Stemona sessifolia contains Stemona alkaloids (stenine, stemonidine, sessiline) which are potent respiratory toxicants. The primary concern is the use of Stemona-containing products in topical applications where inhalation exposure is possible (e.g., sprays, powders). These alkaloids are classified as potentially carcinogenic and have been associated with severe respiratory and neurological effects in occupational settings. EU regulatory authorities have expressed concern about Stemona-containing ingredients, placing this ingredient in the restricted-use category rather than freely permitted cosmetic use.

Skin benefits

  • Traditional use for cough and respiratory conditions; not a skin-care traditional use
  • Anti-parasitic properties; not applicable to cosmetic formulation

Known concerns

  • Stemona alkaloids are potent respiratory toxicants; inhalation hazard in spray/powder applications
  • Classified as potentially carcinogenic; EU import and use highly restricted
  • Not recommended for use in any cosmetic product category due to toxicity profile
