I haven’t used this herb yet, but have heard good things about it pertaining to memory retention and recall. Although, those people were also taking gingko, panax ginseng, and guto kola. Ayurvedic uses have this herb in many of their formulas.
“This plant is a member of the Solanaceae family and has over 4,000 years of traditional use in its native India, Pakistan and Sri Lanka. It is a Medharasayan which is the Ayurvedic category of foods and nutrients that promote learning and memory retrieval. It is sometimes referred to as “Indian Ginseng” as it is traditionally used in conditions of debility, emaciation, impotence and premature aging. It is also sometimes referred to as Winter Cherry. The translation of Ashwagandha is roughly, “the smell and strength of a horse”, alluding to its aphrodisiac properties. This plant is a Tonic and an Adaptogen. In the Middle East it is used to help promote normal sleep patterns and encourage a healthy inflammatory response.
Adaptogens support the ability of an organism to cope with stress and thereby conserve energy. Ashwagandha rejuvenates and tonifies the entire system, especially the endocrine and immune systems. …”
