Despite the current preoccupation with synthetic chemistry as a vehicle to find or discover and manufacture drugs, the contribution of plants to health treatment and prevention is still enormous and many more. Even at the beginning of 21st century, 11% of the 252 drugs considered as basic and fundamental by the WHO were exclusively of flowering plant origin.
