A flurry of new research from around the world on Ashwagandha is proving the medicinal effects of this ancient Ayurvedic herbal remedy are more than just anecdotal.

The past year has been banner year for Ashwagandha research. Numerous studies confirmed its healing properties in a variety of conditions, including stress, toxicity, heart disease, Alzheimer’s disease, diabetes, Parkinson’s, skin cancer, tuberculosis, liver toxicity and many others. Following is a summary of some of the findings of the over fifty different human, laboratory and animal studies conducted using Ashwaghanda published during 2012 and early 2013:

  • Scientists from the Indian Institute of Technology found further evidence of Ashwagandha’s neuroprotective effects, in its ability to withanolide A to inhibit acetylcholinesterase.
  • Research from the Council of Scientific and Industrial Research Center found that Ashwagandha significantly stimulates the immune system.

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 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.
