The Side Effects of Ashwagandha

Ashwagandha is an Ayurvedic remedy claimed to be good for many conditions, including stress, fertility, depression and cancer, but there is inadequate data to prove its effectiveness, according to NYU Langone Medical Center. The roots, leaves and fruit of the ashwagandha plant are used medicinally. A typical dosage is 1 to 2 grams three times a day. Ashwagandha is classified as an adaptogenic herb, meaning that it may help restore normal bodily function and resist the damage that stress causes. Consult a healthcare provider before using ashwagandha.
