Indications
Aswagandha (also spelled Ashwagandha, Withania somnifera) is a root used in Ayurvedic medicine. It is traditionally used as a general tonic to improve energy, strength and wellbeing, to help the body cope with stress, to support sleep and as part of tonic preparations such as Chyawanprash. Some small studies suggest it may reduce stress and improve sleep, but scientific evidence is limited and it is not a cure for any disease.
How It Works
Aswagandha contains natural compounds called withanolides. It is described as an “adaptogen”, meaning it is believed to help the body adjust to physical and mental stress, partly by lowering the stress hormone Cortisol. It may also have a mild calming effect.
Dosage and Administration
Take as directed on the label or by a registered Ayurvedic practitioner. Tonic pastes such as Chyawanprash are usually taken by the spoonful once or twice daily, often with milk. Do not exceed the recommended amount, and avoid long-term use without advice.
Interactions
Aswagandha may add to the effect of sedatives and sleeping medicines (such as Diazepam), medicines for diabetes (blood sugar may fall too low), medicines for high blood pressure and thyroid medicines such as Levothyroxine. It may reduce the effect of medicines that suppress the immune system. Tell your doctor about all medicines you take.
Contraindications
Do not use in pregnancy, if you are allergic to the plant, or if you have an overactive thyroid. Avoid if you have an autoimmune disease (such as lupus or rheumatoid arthritis) unless a doctor agrees, and stop at least 2 weeks before planned surgery.
Side Effects
- Stomach upset, diarrhoea or nausea
- Drowsiness
- Headache
- Rarely, liver injury has been reported
Get urgent medical help if you notice yellowing of the skin or eyes, dark urine, severe tummy pain, or signs of a serious allergic reaction such as swelling of the face or difficulty breathing.
Pregnancy and Lactation
Do not use Aswagandha during pregnancy, as it has been linked to a risk of miscarriage. Avoid while breastfeeding because safety has not been established. Many tonic pastes also contain sugar and several herbs, so ask a doctor first.
Precautions and Warnings
Use with care if you have diabetes, low or high blood pressure, thyroid disease or liver disease. It may cause drowsiness, so be careful when driving. Do not give to children without advice. Herbal products can vary in strength and quality, so buy from a reliable source.
Overdose
Large amounts may cause severe stomach upset, vomiting and diarrhoea. Seek medical advice if a large amount has been taken.
