The chemical composition of propolis from stingless bees is affected by several factors including vegetation type and species. In Kenya, we have diverse landscape vegetation and over 12 stingless bee species. Lifestyle diseases are affecting more people due to unhealthy diets and exposure to harmful chemicals, which lead to oxidation in cells. This led to the production of super radicals, which cannot be neutralized only by the endogenous antioxidants in the body.
