Plant Part Used



Coleus is a relatively new medicinal herb in the United States, although it has been extensively researched in India over the last twenty years. Scientists are currently looking into the plant’s possible function as an anti-hypertensive, or hypotensive agent for blood pressure control. Additionally, many of the components of the whole plant may act in concert to improve the activity of coleus within the body. A standardized extract is derived from the leaf of this plant.
