Identification
Morphology
Strophanthus sarmentosus is a distinctive plant characterized by its shrub-like growth form. It possesses an obligatory climbing habit, meaning it relies on external structures to ascend toward the light. While it can reach impressive heights of up to 25 meters, it frequently settles at a more modest maximum of approximately 6.1 meters. This versatile climber plays a dynamic role in its natural ecosystem through its climbing nature.

Biological Activities
Compounds
Conditions
Strophanthus sarmentosus extracts demonstrate significant efficacy in treating the venom produced by Echis ocellatus. These plant extracts provide vital anti-hemolytic and anti-hemorrhagic activities that help mitigate the damage caused by snakebite. Research shows that the plant effectively treats envenomation by providing protective effects comparable to or better than antivenom. Furthermore, Strophanthus sarmentosus assists in the digestion of the vasoactive neuropeptide bradykinin by inhibiting snake venom metalloproteinases. This ability to inhibit venom-induced processes supports the traditional medicinal use of the plant as a first aid treatment.
Preparations
Strophanthus sarmentosus is prepared as various extracts for medicinal research and traditional applications. Specifically, the plant is processed into methanol and ethylacetate extracts derived from its leaves and roots. These specific preparations are used to investigate the plant's efficacy against snake venom. The methanol and ethylacetate extracts have demonstrated significant anti-hemorrhagic and anti-hemolytic activities. Through these extraction methods, the bioactive components of the plant are isolated to study their inhibitory effects on venom proteases.
