Indications
Trachyspermum ammi is ajwain (carom seed), a common kitchen spice and medicinal plant. In Unani and Ayurvedic medicine, ajwain and its distilled water (arq) are traditionally used for indigestion, wind and bloating, stomach cramps, colic, loss of appetite and mild diarrhoea, and sometimes for coughs and colds. Scientific evidence for these uses is limited.
How It Works
Ajwain seeds contain an aromatic oil rich in thymol. Thymol relaxes the smooth muscle of the gut, easing cramps and helping trapped gas pass (a carminative effect), and may increase digestive juices. Thymol also has antiseptic properties against some bacteria and fungi in laboratory studies.
Dosage and Administration
Take by mouth as directed on the label or by a registered practitioner. Distilled waters (arq) are usually taken after meals. Do not exceed the stated dose. For children, use only a dose advised on the label or by a practitioner.
Interactions
- Ajwain may slow blood clotting slightly; use with care with Warfarin, Aspirin, Clopidogrel and other blood thinners.
- It may lower blood sugar slightly; people taking diabetes medicines should monitor their sugar.
Contraindications
Do not use if allergic to ajwain or related plants (such as cumin, fennel, coriander or celery). Avoid medicinal doses if you have stomach ulcers, severe acidity or liver disease, unless a doctor advises it.
Side Effects
Usually well tolerated in normal amounts. Large amounts may cause heartburn, nausea or a burning feeling in the stomach. Rarely, skin rash or sensitivity to sunlight may occur.
Get urgent medical help if you have severe stomach pain, vomiting blood, black stools, or signs of an allergic reaction such as swelling of the face or difficulty breathing.
Pregnancy and Lactation
Ajwain used as a spice in food is considered safe. Medicinal doses are not recommended in pregnancy, as large amounts have traditionally been linked to effects on the womb. Ask a doctor before using medicinal amounts while breastfeeding.
Precautions and Warnings
- See a doctor if diarrhoea lasts more than 2 days, or if stomach pain is severe, keeps coming back, or comes with fever or blood in the stool.
- For babies with colic, ask a doctor before giving any herbal product.
- Stop 2 weeks before planned surgery.
Overdose
Large amounts, especially of ajwain oil, may cause nausea, vomiting, dizziness and stomach pain. Get medical help if a large amount has been taken, especially by a child.
