Bacopa monnieri, or water hyssop, is a creeping marsh plant commonly used in Ayurvedic medicine. It is often taken to improve cognitive function and memory, relieve stress and anxiety, and enhance general mood and vitality.[1] Bacopa monnieri likely interacts with the dopamine, serotonin, and cholinergic systems, and it may promote neuronal communication by increasing the growth of dendrites (branches off of neurons). Bacopa monnieri also has antioxidant and anti-inflammatory properties.[2]
