Double-blinded Randomized Controlled Trial For Immunomodulatory Effects Of Tulsi (Ocimum Sanctum Linn.) Leaf Extract On Healthy Volunteers
Notes for this study:
|Number of Subjects
300mg of an ethanolic extract of Tulsi leaves was able to increase the levels of IFN-y, IL-4 and T-helper cells (cells and cytokines of the immune system) after 4 weeks, but this increase went back to baseline after the group using Tulsi ceased usage. NK cell activity also increased.
Only side effects were nausea in one subject and loose stools in another.
