Science
Mechanism of Action
This extract operates via multiple synergistic pathways within the skin. Its robust antioxidant action stems from a diverse profile of phytochemicals including flavonoids, alkaloids, tannins, and phenols, which effectively scavenge free radicals. Anti-inflammatory effects are mediated by flavonoid compounds that regulate arachidonic acid metabolism through the inhibition of cyclooxygenase (COX) and lipooxygenase activities. Furthermore, it demonstrates antityrosinase activity, a crucial step in inhibiting melanin synthesis to improve skin luminosity and reduce hyperpigmentation. Its antibacterial properties are effective against key acne-contributing bacteria, specifically Propionibacterium acne and Staphylococcus epidermidis.

Stability
The active compounds within the extract are sensitive to both temperature and light, exhibiting multiple absorption peaks across the ultraviolet and visible regions. To maintain compound integrity and efficacy, crude extracts are typically stored at 4°C.
Safety
Safety Profile
Formal safety assessments by regulatory bodies such as CIR, SCCS, or FDA are not readily available. In vitro studies have indicated moderate to high cytotoxicity at elevated concentrations (e.g., LC50 of 29.65 μg/mL in brine shrimp; moderately toxic at 1000 ppm and highly toxic at 4000 ppm in HepG2 cells). Conversely, acute oral toxicity tests in rats showed an LD50 exceeding 5000 mg/kg with no fatalities, suggesting low acute systemic toxicity via this route. Notably, a topical cream formulation containing the extract was reported not to cause skin irritation.
