Bacopa monnieri, commonly known as water hyssop, is an herb often used in Ayurveda.
Supplementing Bacopa monnieri has been shown to improve cognition, by means of reducing anxiety. It is also reliable for improving memory formation. Though effects of this nature are usually studied in the elderly, Bacopa monnieri appears to affect young people as well, making it a useful nootropic.
Since Bacopa monnieri is also an adaptogen, a relaxed person might experience a lack of motivation to work after supplementation. Theoretically, pairing Bacopa monnieri with a stimulant would ward off malaise, but this combination has not been tested.
Bacopa monnieri interacts with the dopamine and serotonergic systems, but its main mechanism concerns promoting neuron communication. It does this by enhancing the rate at which the nervous system can communicate by increasing the growth of nerve endings, also called dendrites. Bacopa monnieri is also an antioxidant.
Taking Bacopa monnieri on an empty stomach may cause nausea, cramping, bloating, and diarrhea.
