Usage of herbs and spices for enhancing immunity and to suppress mental depression are not new. Among these, ‘Ashwagandha’ finds its importance as a household remedy, especially its root powder as the best nerve tonic for old people and children and aphrodisiac for the young. It has been a prized top notch adaptogenic (to resist all kinds of stress) tonic for centuries in India. It is also known as Indian Ginseng as it compares well with Siberian and Panax Ginseng  in its stress-relieving properties. Even the Ministry of Health has recommended ‘Ashwagandha’ to strengthen the immune system and mental well-being of patients recovered from Corona illness as one of the AYUSH medicines.

The name ‘Ashwagandha’ is derived from Sanskrit word ‘Ashva,’ meaning horse and ‘gandh’ denoting smell referring to the horse-like odour emanating from its root. Its scientific name is Withania somnifera, a plant in the Solanaceae (Tomato family). Withania is named after Henry Witham, an English palaeobotanist of the early 19th century. The species name somnifera denotes “sleep-inducing” in Latin.
