Science
Mechanism of Action
This extract contains alkaloids that primarily exert anti-inflammatory effects by modulating inflammatory pathways and inhibiting the release of allergic mediators, which can visibly reduce skin redness. Furthermore, it acts as an antioxidant, actively scavenging free radicals to protect skin cells from oxidative stress and thereby supporting healthy skin function. Its conditioning properties contribute to maintaining a soft, smooth texture, while animal studies suggest its potential to temper overactive immune responses and its astringent qualities can assist in firming the skin.

Safety
Safety Profile
Generally considered safe for topical cosmetic application, with a low irritancy and comedogenicity profile according to INCIDecoder. However, due to the potential for skin irritation, redness, or allergic reactions in sensitive individuals, a preliminary patch test is recommended prior to widespread application. For oral consumption, this ingredient carries a higher risk, with reports of kidney and liver toxicity at large doses or long-term use. Concerns also exist regarding potential misidentification with herbs containing nephrotoxic aristolochic acids, and oral use is contraindicated during pregnancy, lactation, or in cases of severe liver or kidney impairment.
