Medicinal plants have been a major source of medications since antiquity. The important thing to remember is that there are numerous life-saving drugs available, either directly as extracts or in modified synthetic form. Calotropis gigantea is a massive shrub with several branches that is gregarious. Its younger branches produce milky latex and cottony, white hairs. Often called "milkweed," this plant is found almost everywhere in the world and is native to China, Malaysia, and India. The Siddha, Ayurvedic, and Unani medical systems have long used it. This medicinal plant has a broad variety of isolated compounds, including alkaloids, tannins, resins, flavonoids, terpenoids, cardiac glycosides, and certain chemical compounds including giganteol, α and β calotropeol, β-amyrin, giganteol, and isogiganteol. In addition to these chemical compounds, C. gigantea has some pharmacological action, including anti-asthmatic, antioxidant, antibacterial, antiviral, wound healing, anti-inflammatory, anti-diarrheal, hepatoprotective, and hypoglycemic properties.
