Key findings

  1. 01 Sanguinarine and chelerythrine showed antimicrobial activity against Mycobacterium aurum (IC50 values of 9.61 µg/mL and 7.30 µg/mL respectively).
  2. 02 Extracts and alkaloids exhibited cytotoxic activity against human melanoma cell lines in vitro (extracts 0.88-10.96 µg/mL, alkaloids below 0.55 µg/mL).

Transparency

Not commonly dusted

Given severe toxicity and controversial historical use in oral products and 'black salves', the issue is outright safety rather than ineffective low-dose inclusion in cosmetics. Its unpredictable effects preclude safe cosmetic application.
