Ashwagandha has been used for over 3000 years, thus from its mere traditional usage, it has evolved to the modern capsule supplement where people can get it easily, anywhere. Though there are many health benefits of ashwagandha, but some of it does not have a conclusive study finding.
The available scientific data support the conclusion that Ashwagandha is a regenerative tonic, due to its multiple pharmacological actions like anti-stress, neuroprotective, antitumor, anti-arthritic, analgesic and anti-inflammatory.

Ashwagandha and mental health (4,5)
Ashwagandha induced a calming anxiolytic (anti-anxiety) effect that was comparable to the drug Lorazepam in all three standard tests, anxiety tests (the elevated plus-maze), social interaction and the feeding latency in an unfamiliar environment. Moreover, both Ashwagandha and Lorazepam, reduced rat brain levels of tribulin, an (marker of level of anxiety).
Ashwagandha also exhibited an antidepressant effect, comparable with that induced by imipramine, in two standard tests, the forced swim-induced ‘behavioural despair’ and ‘learned helplessness’ tests. The investigations support the use of Ashwagandha as a mood stabilizer in clinical conditions of anxiety and depression.
Another study that was conducted using prospective, randomized controlled double-blind method found that, the group that was given ashwagandha root extract exhibit a significant reduction in hormone cortisol level (stress hormone) as compared to the group that receive placebo.
