Ashwagandha

Ashwagandha has been a cornerstone in Ayurvedic medicine for over 3,000 years. It is traditionally used as a Rasayana (rejuvenative) herb, believed to promote longevity, enhance energy, and improve overall health. It has been utilized for reducing stress, improving sleep, enhancing strength, and as an aphrodisiac.
