Yavani for colic
Antispasmodic, used for cramping abdominal pain in adults and, as a weak water, in infants.
Yavani for indigestion
A sharp Deepana and Pachana drug for poor appetite and heaviness after meals.

Frequently asked questions
What is ajwain used for?
Bloating, trapped wind, colic, indigestion, cough and worms. A teaspoon with a pinch of rock salt followed by warm water is the standard Indian household remedy for wind, and it works reliably.
What is the dose of Yavani?
Seed powder 1–2 g per day, or a teaspoon of seeds chewed with rock salt. As ajwain water, a teaspoon of seeds boiled in a cup of water. Culinary quantities need no limit.
Can ajwain water be given to babies?
A very weak ajwain water is traditionally given for infant colic across India, and a warm ajwain potli applied to the abdomen is the safer external version. Use it weak, and see a doctor for persistent infant crying.
Is ajwain good for acidity?
Only for the kind caused by sluggish digestion and trapped wind. It is heating and can aggravate true hyperacidity and reflux, where cooling demulcents such as Yashtimadhu or Shatavari are the better choice.
Who should avoid ajwain?
Anyone with hyperacidity, peptic ulcer or an inflammatory gut condition, since it is strongly heating. Avoid medicinal doses in pregnancy. Take advice if you are on blood thinners.
What is an ajwain potli?
Seeds dry-roasted, tied in a cloth bundle and applied warm to the abdomen or chest. It is used for colic, period pain and chest congestion, and is a genuinely useful domestic measure that carries none of the cautions of internal use.
What is ajwain called in English?
Carom seed, bishop's weed or ajowan. The botanical name is Trachyspermum ammi. Its sharp thyme-like flavour comes from thymol, which is also the source of its antimicrobial action.
