Mentat is a broad spectrum ayurvedic medication containing only natural plant extracts. It improves mental function by modulating a process of cholinergic neurotransmission. It is aimed to promote an action of cortical, muscarine and cholinergic receptors. As a result it facilitates brain activity by stimulating memory function and concentration ability. It relives a stress and stimulates stress resistance. It possesses anti-oxidant properties that help to keep brain cell integrity. Mentat lowers the level of trubulin (an endogenous amine oxidase monoinhibitor) that is produced in the state of anxiety. It is a relaxant used to prevent convulsions and insomnia. It improves articulation and eliminates speech defects.
