Stress is one of the factors which affect aging. Cortisol is the body’s stress hormone, and it leads to muscle loss and wrinkles, even cognitive impairment. But Ashwagandha slows down the aging process by putting the production of cortisol to a halt. Similarly for someone looking to boost sexual stamina, Ashwagandha can work wonders. The mystical herb enhances vitality by increasing blood flow and reducing body tension. Alternately, this acts as the perfect libido enhancer and has even been mentioned in Kama Sutra, one of the oldest surviving texts on human sexuality.
