Ashwagandha (Withania somnifera) is a popular herb in the Ayurvedic system of medicine. It is a small shrub that belongs to the Solanaceae family. It might be useful for different diseases and mostly as a nervine tonic (has a soothing effect on nerves). Ashwagandha is commonly called Indian Ginseng or Indian winter cherry. Ashwagandha is known for its rasayana (tonic) property. Rasayana is a herbal or metallic formulation that stimulates a youthful physical and mental state of health as well as happiness1.
Ashwagandha is cultivated in dry regions of South Asia, Africa, and Central Asia. More than 50 chemical constituents have been isolated from different parts of the ashwagandha plant1.

Ashwagandha is also called an ‘adaptogenic’ herb or a ‘royal’ herb since it helps reduce stress and helps your body adapt to changes. It rejuvenates various body systems like the immune, reproductive and endocrine systems9.

The potential uses of ashwagandha for human health are as follows:
Ashwagandha might have anxiolytic (anxiety-relieving) properties that are similar to that of the drug lorazepam. Both ashwagandha and lorazepam showed to help reduce anxiety in animal models. Ashwagandha might also exhibit potential antidepressant properties. This indicates that Ashwagandha might help with depression and anxiety1. However, more research is required. Anxiety and depression may need serious attention and one should seek medical help from a professional for it.
Ashwagandha might have potential anti-arthritic properties that may be widely accepted and reported. Ashwagandha might help relieve pain by soothing the nervous system. In an experimental study6, patients were given a formula containing ashwagandha. This herbal formulation showed the potential to reduce the severity of pain and disability1,4. However, arthritis is a serious condition and must be diagnosed and treated by a doctor.
Ashwagandha is a popular Ayurvedic rasayana and belongs to medhyarasayanas, a subgroup of rasayanas. Medhya means mental/intellectual ability. Ashwagandha might help enhance memory and intelligence. This potential of ashwagandha for cognition was seen in children with compromised memory and old age as anecdotal evidence1. However, such claims lack scientific backup. Therefore, more research is required.
The circulatory system and cardiovascular health are adversely affected due to mental stress. Stress also affects the body’s antioxidant defence system7. Ashwagandha might help the body adapt to stress. It may also be effective in improving mental and physical health5. However, more research is required to ascertain such claims.
In a study8, treatment with an aqueous extract of ashwagandha showed potential to increase the pain threshold (a point beyond which a trigger produces pain) compared to that of placebo, showing that ashwagandha might be an analgesic agent. However, further research is required to state these as concrete facts.
Ashwagandha might help deal with problems related to sleep and may contain sleep-inducing properties. It might also help one fall asleep faster and have an improved sleep quality7.
Though there are studies that show the potential uses of ashwagandha in various conditions, these are insufficient and there is a need for further studies to establish the true extent of the benefits of ashwagandha on human health.
Ashwagandha may be helpful in combating hair loss and promoting hair growth. Hair loss usually occurs due to stress. The lactones present in ashwagandha can reduce the levels of cortisol hormone in the body, which relieves stress10.

Ashwagandha is derived from two words: ashwa, meaning ‘horse’ and gandha, meaning ‘smell’. It is named so because the fresh roots of ashwagandha emit the smell of a horse. It is believed to boost vitality and strength in your body, comparable to a horse11.

While ashwagandha is generally not associated with weight gain, some studies suggest it may support weight management by reducing stress-related overeating and regulating cortisol levels. However, individual responses may vary, and it’s advisable to consult with a healthcare provider before incorporating ashwagandha into a weight management regimen.
Ashwagandha has been studied for its potential to increase testosterone levels in men with low levels or infertility issues, attributed to its ability to reduce stress and improve overall hormonal balance. While research shows promising results, individual responses may vary, and consulting with a healthcare professional is advisable before using ashwagandha for this purpose.
