- The plants are both empirically and scientifically used as antiinflammatory, antidiabetic, antimalarial, antiviral, antihypertensive, hypolipidemic, antioxidant, antitumor and anticancer.
- esults of the molecular docking simulation of chemical content of these plants could potentially provide an anticancer effect
- Roots are basically used as treatment of snake bites. Take a piece of the root the size a thumb, chew and swallow the liquid while the residue is applied over the bites.
