Melianthus major
Striking South African shrub with toxic foliage historically applied externally for rheumatism, wounds, and inflammation despite its dangerous systemic toxicity.
Melianthus major is a highly toxic South African shrub traditionally used externally for rheumatism, wounds, and snake bites. Its primary bioactive constituents include melianthus toxins, cardiac glycosides, and terpenoids, which confer both anti-inflammatory and cardiotoxic properties. Due to its severe systemic toxicity, it is strictly limited to topical application under professional guidance.
The cardiac glycosides in Melianthus major inhibit the Na+/K+-ATPase pump in cardiac myocytes, increasing intracellular calcium and enhancing contractility, which can lead to arrhythmias and toxicity upon systemic absorption. Terpenoid compounds exhibit anti-inflammatory activity by modulating cyclooxygenase (COX) and lipoxygenase (LOX) pathways, reducing prostaglandin and leukotriene synthesis. The plant's toxins also disrupt cell membrane integrity, contributing to its wound-healing effects through controlled local irritation and immune modulation.
