Jatamansi (Nardostachys jatamansi) is a herb traditionally used in Ayurvedic and Unani medicine for its calming, neuroprotective, and adaptogenic properties. Its use in relation to the dopamine system is largely based on traditional claims that it helps balance "nervous system disorders," improve cognition, and act as a mood stabilizer. Practitioners historically have recommended jatamansi for conditions associated with anxiety, depression, and insomnia—states now sometimes associated with dopaminergic dysfunction in modern neurobiology.

Scientific studies on jatamansi are limited, especially with respect to its direct effects on dopamine pathways in humans. Some in vitro and animal studies suggest neuroprotective and antioxidant effects, and a few have indicated that extracts may influence monoamine neurotransmitters, including dopamine, but these findings are preliminary and not robustly replicated. There is insufficient clinical evidence to firmly establish its efficacy or mechanism in modulating dopamine in humans.

In summary, while jatamansi is traditionally used to support mental health and the nervous system—which may overlap with dopaminergic activity—the direct scientific validation for its specific action on the "dopamine body system" is weak. Its use in this context remains grounded more in historical practice than in solid modern evidence.
