Science

This extract exerts its effects through key bioactive compounds such as myristicin and diayangambin. Myristicin plays a role in modulating nitric oxide release, a critical component of the body's natural anti-inflammatory processes, while diayangambin specifically inhibits pro-inflammatory cytokines. The extract has been shown to reduce IL-6 and NF-κB gene expressions in human cell lines. As an antioxidant, it leverages lignans to neutralize free radicals, thereby protecting skin cells from oxidative stress and mitigating signs of premature aging. It also exhibits antimicrobial and antifungal activities, aids in tissue regeneration, supports the skin's moisture barrier, and helps balance sebum production for oily skin types. Traditionally, it is recognized for its analgesic effects and ability to draw out impurities.

Safety

CIR Status
Not reviewed
Sensitization risk Unknown

No specific topical safety assessments from regulatory bodies like CIR, SCCS, or FDA were found. Traditionally, ingested concentrations of its active metabolites are considered well below established toxicity thresholds. While myristicin, a key compound, can induce psychoactive or hepatotoxic effects when consumed in extremely high quantities, its concentrations in typical topical applications or traditional infusions are generally regarded as therapeutic and non-toxic.
