Traditional uses

  • Memory and concentration
  • Anxiety and restlessness
  • Sleep
  • Supportive care in epilepsy (Apasmara) — never instead of anti-seizure medicine

These are uses described in Ayurvedic practice; they are not all supported by clinical research.

What research shows

Several randomised trials, mostly in healthy older adults, show small improvements in memory and attention after about 12 weeks. Evidence for anxiety is limited.

Safety

Avoid or ask a doctor first if you have:
  • Slow heart rate
  • Pregnancy and breastfeeding
  • Stomach ulcers

Possible interactions

  • Sedatives, sleeping pills, antidepressants — added drowsiness
  • Thyroid medicines
  • Medicines that slow the heart

Side effects

Nausea, stomach cramps, loose stools and tiredness are the most common side effects; taking it with food helps.

Stop and seek medical advice if you develop yellow eyes or skin, dark urine, a rash, or feel unwell after starting any herbal product.

Buying safely

  • Buy licensed products whose label shows the manufacturer's name and address, an AYUSH licence number, batch number and expiry date.
  • Prefer products that name the botanical species and the part used.
  • Be wary of products promising cures, “no side effects”, or rapid results — some have been found to contain hidden steroids or other drugs.
  • Tell every doctor and pharmacist about all the herbal products you take.
  • Report side effects through the Ministry of Ayush pharmacovigilance programme. See our Ayurvedic medicine safety guide.
