Ashwaghanda Summary:

Ashwaganda (Withania somnifera) is commonly referred to as Indian ginseng. Although it's used very similarly to Panax ginseng, it isn't as stimulating, and completely different chemical profile to ginseng.

Ashwaghanda is slightly sedative, which makes it perfect for anybody weak from over stimulation. This can include things like exhaustion due to overwork, ADHD, stress induced weakness, and hyperactive thyroid conditions. It's a perfect herb to take on a daily basis for these types of conditions, and as a general tonic for people who are naturally a bit anxious or overstimulated. 

In the Ayurvedic medical system, where ashwaghanda is well used, it's mainly indicated for impotence and age related conditions. It is considered a rasayana, which is a tonic herb thought to have a high level of safety and efficacy, especially with long term use. 

Ashwaghanda can be made into a decoction, taken as a tincture or liquid extract, or powdered and mixed in with smoothies or packed into capsules.

Traditional uses

Ashwaganda is an improtant Ayurvedic herb for conditions involving debility, emanciation, impotence, bronchitis, wasting (children), insomnia, leukoderma, lumbago arthritis, rheumatism, lumbar pains, to promote conception, and premature aging. It was also used as a nutrient for pregnant women, and to improve energy for any constitutional diseases. [1, 2]. 


Botanical Description

Ashwaganda is a member of the Solanaceae (nightshade) family. This is the same family as such plants as tomato, and eggplant. This perennial shrub grows to about 1.5 m in height [1].

Harvesting Collection, and Preparation:

Still compiling research. 



Ashwaganda contains lactones (withaferin A, sitoindoside IX, X), and acylsteryl glucosides, as well as alkaloids (tropane) including tropine, pseudotropine, and other alkaloids such as isopelletierine and anaferine. [1, 2]. 

Alkaloids, steroid lactones (withanolides and withaferins), iron. 


Pharmacology and Medical Research:

+ Adaptogen

Adaptogens increase the bodies ability to recover from and resist stress. There have been a number of studies investigating the adaptogenic activities of ashwaganda. Many of these studies have found evidence of this action in various forms of stress induced damage. [1].

+ Anxiety

In a double blind, placebo controlled trial consisting of 39 patients diagnosed with generalised anxiety disroder, patients treated with Ashwagandha extract (1000mg/day representing about 6-8g of root for 6 weeks) noted a significant benefit in comparison to the placebo group. Both groups in this study showed improvement. [11].

+ Blood Glucose Regulation

An open label trial involving a Withania somnifera extract and 6 type two diabetics demonstrated a 12% reduction in blood glucose levels. [12].

+ Cancer

Ashwaganda has been demonstrated to produce an antitumoral activity using a few different mechanisms: [1, 2, 4-7]

  1. Regulation of cell cycle proliferation [1, 7-9]
  2. Increased tumor apoptosis [1, 4, 6, 7]
  3. Inhibition of angiogenesis [1]
  4. Suppression of NF-kB [1, 2]
  5. Increased immune activity [1] Much of the scientific research in this area has been on withaferin A, which is generally regarded as the most significant component in this area [1, 2, 7].

+ Inflamation

Withaferin A was shown to inhibit IL-1beta production in the dendritic cells through regulation of Nf-kB and NLRP3 inflammasome activation induced by H. pylori. This has significance in the prevention of H. pylori induced gastric cancer development. [2].



Ashwaganda has a very high level of safety, with no reported side effects. [10].  



Due to recent worries involving lead contamination in parts of India, caution is advised for herbs such as withania that have been grown in India.
