Bioassays of inflammation pathways from combination of moringa oleifera, capsaicin and menthol

Moringa oleifera is a multi-purpose plant native to Africa and Asia. Many studies have shown the medicinal value of its edible leaves, pods and seeds in treating inflammation and various diseases. The leaf is the most investigated part of this plant for its rich secondary metabolites, vitamins and m...
