Antimicrobial activity and cytotoxic effects of stachytarpheta jamaicensis (L.) vahl crude plant extracts

Medicinal plants are known for their ability to treat diseases due to the presence of bioactive constituents such as alkaloids, phenolic compounds, saponin, tannins and terpenoids. They can be used as anti-inflammation, antioxidants, antibiotics and anti infection drugs. Stachytarpheta jamaicensis (...
