Hypocholesterolemic activity of nut shell extract of Semecarpus anacardium (Bhilawa) in cholesterol fed rabbits.

Administration of S. anacardium nut shell extract to cholesterol fed rabbits resulted in a significant reduction in serum cholesterol (-73.3%) and serum LDL-Chol. (-80%). The extract feeding also prevented the accumulation of cholesterol/triglycerides in liver, heart muscle and aorta and caused a regression of plaques (75.3-83.5%). These results indicate that S. anacardium is hypocholesterolemic in action and prevents cholesterol induced atheroma. Possible mechanism of action is discussed.
