To reduce stress and anxiety
A few studies suggest ashwagandha may be helpful for anxiety and stress.
To treat diabetes
Lab studies suggest that ashwagandha may improve type 2 diabetes. Human studies are needed.
To reduce fatigue
Results from a small study in patients with cancer-related fatigue suggest benefit. Additional studies are needed to confirm this.
To reduce pain
A clinical trial suggests that a standardized extract may help patients with knee joint pain. Mild side effects like nausea and stomach irritation were observed in a few patients.
To treat rheumatoid arthritis
A clinical trial showed that a compound of herbs and minerals containing ashwagandha reduced rheumatoid arthritis pain. Because the formula contained multiple herbs and minerals, whether ashwagandha played a role in observed benefits is unclear.
Although the herbs are natural  and from nature we would still advise to consult with your doctor before taking any of these herbs
