Science
Mechanism of Action
This extract exerts its multi-faceted actions through a rich array of phytochemicals, including alkaloids (such as vasicine and vasicinone), saponins, tannins, and flavonoids. Its anti-inflammatory effects are mediated by suppressing pro-inflammatory mediators, like prostaglandins, and inhibiting the MAPK signaling pathway. As an antioxidant, it efficiently scavenges free radicals, while its antimicrobial properties against various bacteria (e.g., E. coli, S. aureus, P. aeruginosa) and some fungi are primarily due to its alkaloid and tannin content. It also promotes wound healing by stimulating collagen synthesis and increasing fibroblast proliferation.

Key findings
- 01 An in vitro study demonstrated that an ethanolic leaf extract, at a concentration of 250 µg/ml, exhibited 86.5% anti-DPPH radical activity, showcasing significant antioxidant power comparable to Vitamin C at elevated concentrations.
- 02 Both in vitro and in vivo models have confirmed the leaf extract's promising anti-inflammatory, analgesic, and antioxidant activities.
- 03 In vivo research indicates that compounds within the extract can mitigate imiquimod-induced skin inflammation by inhibiting the MAPK signaling pathway activation.
- 04 Topical application in experimental models has been observed to accelerate wound healing through enhanced collagen synthesis and fibroblast proliferation.
