Pharmacology :

Bacoside A assists in release of nitric oxide that allows the relaxation of the aorta and veins, to allow the blood to flow more freely through the body. Therefore Brahmi is revered for strenghtening the immune system, improving vitality and performance and promoting longevity. Bacoside B is a protein valued for nourishing the brain cells, as a result Brahmi improves mental clarity, confidence, intelligence and memory recall. Asiaticosides stimulate the reticuloendothelial system where new blood cells are formed and old ones destroyed, fatty materials are stored, iron is metabolized, and immune responses and inflammation begin. The primary mode of action of Centella appears to be on the various phases of connective tissue development, which are part of the healing process.
