Verdict

Contains hydroxystilbenes with selective ERβ agonist activity demonstrating potent estrogenic effects in vitro; endocrine disruption potential must be assessed. As a skin-bleaching agent, monitor for hydroquinone-like effects and ensure compliance with EU restrictions on skin-lightening claims. Batch-to-batch consistency of active constituents (rhaponticin, desoxyrhaponticin, rhapontigenin) must be controlled.

US Note

Not restricted by FDA; botanical extracts must comply with labeling requirements
