Ashwagandha is an adaptogen working on the endocrine system and the Hypo-Pituitary-Axis (HPA)*. The Sanskrit implies it gives the user the strength and stamina of a horse- with some doctors saying that taking it in the morning will allow you to run 20 miles while taking it at night will allow you to sleep like a baby. In clinical practice doctors find it especially useful in patients under increased stress, or with sleep problems, cognition issues and/or various neurological imbalances.*
