A myriad of constituents

Ashwagandha (Withania somnifera) contains a myriad of constituents, including withanolides named withanolide A, withanolide B, withaferin A, and withanone, along with 12-deoxy withastramonolide, withanoside V, withanoside IV. Other complex molecules include trihydroxy-oxowitha-trienolide compounds.

These compounds have been found to act synergistically to enable changes in gene expression within the cell – producing a variety of medicinal effects in addition to antioxidant effects. While some research is striving to isolate and extract that one constituent to be synthetically produced in a lab to make a patented drug, the research above and others over the past year testify that this Ayurvedic powerhouse herb is best used in its whole or whole extract form.
