Science
Mechanism of Action
This extract exerts its therapeutic effects through a rich profile of bioactive constituents. Coumarin is believed to inhibit inflammatory pathways, specifically COX-2, thereby reducing skin inflammation. Beta-carotene contributes to the skin's antioxidant defenses and supports overall skin health, while a blend of flavonoids, including quercetin and apigenin, actively scavenges free radicals, neutralizing oxidative stress in skin cells. This combined action helps to soothe irritation, diminish swelling, and promote skin rejuvenation.

Stability
No specific optimal pH range for the extract's stability in cosmetic formulations has been definitively identified. However, the Hierochloe Odorata plant naturally tolerates mildly acidic, neutral, and mildly alkaline soil conditions, suggesting a broad pH compatibility for its extract.
Safety
Safety Profile
Hierochloe Odorata extract is generally considered safe for topical application. While coumarin, a component of sweetgrass, has known internal toxicity concerns (e.g., liver injury in doses exceeding 4 mg daily when ingested), these risks are primarily associated with high internal consumption and are not typically relevant to topical cosmetic use. Rare instances of mild dermatitis from skin contact or inhalation have been noted. There is currently no specific CIR, SCCS, or FDA regulatory status or defined maximum concentration for its use in cosmetics.
