Brahmi is an incredible herb which has been a mainstay of ayurvedic medicine. The western world refers to brahmi as water hyssop. However, it should not be confused with gotu kola (Centella asiatica). Here are the incredible benefits of brahmi. Brahmi is well-tolerated by many individuals. However, those with low blood pressure and a reduced rate of heartbeat tend to faint, experience dizziness and headache after consuming brahmi powder or supplements and it is hence recommended that such individuals avoid this herb.
