Science
Mechanism of Action
This extract leverages a complex profile of bioactive constituents, including Leucepthalide (a diterpenoid), Luteolin (a flavonoid), and Ursolic acid (a triterpene). Leucepthalide primarily inhibits COX-2 expression, contributing to its anti-inflammatory effects. Luteolin acts as a powerful antioxidant, neutralizing free radicals and modulating the NF-κB pathway to reduce inflammatory responses. Ursolic acid supports cellular membrane integrity and offers mild antimicrobial benefits. Collectively, these compounds inhibit pro-inflammatory mediators such as nitric oxide (NO), tumor necrosis factor (TNF)-α, and interleukin (IL)-1β, while also promoting wound healing and antiseptic conditions within the skin.

Key findings
- 01 Accelerated re-epithelialization by 30% in rat models, demonstrating significant wound healing capabilities.
- 02 Standardized extract reduced paw edema by 45% in rodents via COX-2 inhibition, indicating robust anti-inflammatory action.
- 03 Isolated oleanolic and laballenic acids inhibited LPS-induced nitric oxide, TNF-α, and IL-1β production in macrophage cell lines (IC50 17.12 to 57.20 μM).
- 04 A sub-fraction (LCD-F1) inhibited LPS-induced nitric oxide, TNF-α, and IL-1β production in macrophage cell lines (IC50 15.56 to 31.71 μg/mL).
- 05 Dichloromethane extract (LCD) significantly reduced LPS-induced TNF-α and IL-1β production in Sprague Dawley rats at concentrations of 50, 100, and 400 mg/Kg.
- 06 Crude methanolic extract exhibited antioxidant activity, scavenging DPPH radicals with an IC50 of 421.3 µg/ml.

Safety Profile
While generally well-tolerated, topical application may induce an allergic skin rash in sensitive individuals. Overuse or high concentrations may also lead to an increased burning sensation. Formal safety assessments by regulatory bodies such as CIR, SCCS, or FDA for its use as a cosmetic ingredient are not currently available.
