Ashwagandha, an exotic Indian herb, has remarkable stress-relieving properties comparable to those of powerful drugs used to treat depression and anxiety. In addition to its excellent protective effects on the nervous system, ashwagandha may be a promising alternative treatment for a variety of degenerative diseases such as Alzheimer’s and Parkinson’s. Ashwagandha has powerful antioxidant properties that seek and destroy the free radicals that have been implicated in aging and numerous disease states. Even more remarkable, emerging evidence suggests that ashwagandha has anti-cancer benefits as well.
Scientists speculate that some of ashwagandha’s benefits stem from its antioxidant properties and ability to scavenge free radicals.
Two main classes of compounds—steroidal alkaloids and steroidal lactones—may account for its broad range of beneficial effects. Steroidal lactones comprise a class of constituents called withanolides. To date, scientists have identified and studied at least 12 alkaloids and 35 withanolides. Much of ashwagandha’s pharmacological activity has been attributed to two primary withanolides, withaferin A and withanolide
Other studies reveal that ashwagandha has antimicrobial properties, with antibacterial activity against potentially dangerous bacteria, including Salmonella, an organism associated with food poisoning. This activity was demonstrated in cell cultures as well as in infected laboratory animals.
Additional studies show that ashwagandha root extract enhances the ability of macrophage immune cells to “eat” pathogens, as compared to macrophages from a control group that did not receive ashwagandha
