Ashwagandha: what it is and who should be careful

For information only. Products do not replace diagnosis, treatment or a varied diet. Seek professional advice for symptoms, pregnancy and use by children.

Ashwagandha (Withania somnifera) is a plant from Ayurvedic tradition sold as a dietary supplement, often described as an adaptogen. The word adaptogen is not medical proof of an effect. It helps to know what is known and what is not.

What the official source says

NCCIH states that short-term use, up to about three months, may be safe, but long-term safety has not been established. Drowsiness, stomach upset and diarrhea are possible. Rare cases of liver injury have also been reported.

Who needs to be careful

Pregnant and breastfeeding women should not take ashwagandha. It is not recommended for people with thyroid disorders or autoimmune diseases. It may interact with medicines for blood sugar, blood pressure, thyroid, sedatives and medicines that affect the immune system. Ask a doctor before any surgery as well.

What you can do

1. Write down what bothers you: stress, tiredness or poor sleep, and for how long.
2. If you have a diagnosis or take medicines, ask your doctor or pharmacist before a supplement.
3. Improve the basics: regular sleep, walking, meals and breaks during the day.
4. If you still decide to try it, choose a product with a clear label and watch how you feel.
5. Stop and contact a doctor if you notice yellow skin, strong fatigue or dark urine.

If you still consider a supplement, bring the label to a doctor or pharmacist and ask whether thyroid and liver tests should be checked. Note the start date. Before planned surgery, ask your doctor when to stop using it.
