Common Name: Ashwagandha
Scientific name: Withania somniferum
Synonyms: Indian ginseng, winter cherry
Overview:
Ashwagandha is in the same family as tomatoes, peppers and
potatoes. It is a small, evergreen shrub native to the frost free
regions of India, northern Africa, the Mediterranean and the Middle
East. Ashwagandha stands 2-3ft in heights with oval leaves and yellow
flowers resembling those of the tomato. It has small red fruit about
the size of a raisin. Every part of the plant is used in traditional
medicines in its native regions.
Ashwagandha is considered to be an adaptogen. It helps the body
recover from stressful situations. It has been used for over 2,500
years in India as a general tonic to rejuvenate, strengthen and calm
the nervous system. The active constituents in Ashwagandha are called
withanolides. These withanolides are steroidal in nature and are what
gives this herb its ability to heal and restore.
Benefits
Although research into the benefits of this herb are just beginning,
Ashwagandha is a very important herb in the traditional Ayurveda
medicine of India. Indian healers use Ashwagandha not only as a general
tonic but use it to treat a variety of ailments.
This herb is used to:
- Strengthen and tone the body.
- Help correct memory problems by modifying the way the brain uses acetylcholine (a neurotransmitter).
- Animal
studies have confirmed that the active ingredients in ashwagandha are a
more potent treatment for the pain and swollen joints of arthritis than
synthetic steroids without the immune depressing side affects. Unlike
long term use of aspirin to relieve the symptoms of arthritis, the
active compounds in Ashwagandha do not cause gastro intestinal
bleeding.
- Increase red and white blood cell counts after
treatment with cyclophosphamide, used in the treatment of Hodgkin’s
lymphoma, azathioprine, used to prevent organ rejection and prednisone
used in the treatment of autoimmune diseases like lupus.
- Increase
platelet counts as well as red and white cell counts after
chemotherapy. Studies in India have shown that ashwagandha also makes
cancer cells more susceptible to radiation therapy.
- Relieve stress and promote restful sleep. Ashwagandha has GABA-like compounds that help calm the nerves and encourage sleep.
- In traditional Indian medicine, ashwagandha is used as a “grounding: herb. It increases libido and increases sexual stamina.
