Studies related to Calmness and Centella asiatica

A Double-blind, Placebo-controlled Study On The Effects Of Gotu Kola (Centella Asiatica) On Acoustic Startle Response In Healthy Subjects

Centella asiatica (12g of the plant) appears to reduce anxiety and fear induced by the acoustic startle response (thus, an increase in calmness due to less reactivity) without significantly affecting cardiovascular parameters or mood state in otherwise healthy persons; these occurred with 30-60 minutes of a single dose.
