Tulsi

Tulsi is a variety of basil, however, the flavor is rather different than usual culinary basil. The leaves have a surprisingly fruity scent, which is mirrored in flavor when drank as a tea. Typically used in tea.

Tulsi is associated with potentially normalizing glucose, blood pressure and lipid profiles, and dealing with psycological and immunological stress.
