What Is Ashwagandha?

Uses For Ashwagandha

Overall Health:

Withanolides are key constituents of this herb and play an important role in ashwagandha’s overall ability to promote physical and mental health. In animal studies, ashwagandha has been shown to support the activity of lymphocytes and macrophages, moderate occasional stress, enhance memory and cognitive function, provide neuroprotection by scavenging free radicals, and support thyroid function. A small human clinical trial demonstrated the ability of ashwagandha to support healthy glucose and lipid metabolism. In a double blind, placebo-controlled clinical trial involving 42 volunteers, a formulation including ashwagandha indicated its potential to help promote joint comfort, which may involve modulation of cyclooxygenase enzyme activity. Other research suggests that it may promote relaxation and maintain healthy cortisol and C-reactive protein levels.*
