Yavani

TRADITIONAL VIEW, WITH SAFETY LIMITS

Hindi name: Ajwain

What the texts say Yavani does

• Deepana — kindles digestion (appetiser)
• Pachana — digests ama (digestive)
• Shoolaprashamana — relieves colicky pain
• Krimighna — anthelmintic (against worms)
• Vatanulomana — moves vata downward, relieves wind

What the evidence says. Traditional use is extensive and long recorded. Modern clinical evidence is limited.

Side effects and limits

• Burning sensation and acidity
• Digestive irritation in quantity

Avoid or ask first: Conditions aggravated by ushna and tikshna dravya, including acid dyspepsia and peptic ulcer, in medicinal quantity.; Pregnancy, in medicinal quantity.

A traditional classification, not a recommendation. The full safety record is below.

AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

Thymol-bearing; a gastric irritant at higher quantity. Not the same drug as Ajamoda.

Reported from Sharangadhara Samhita and the Ayurvedic Pharmacopoeia of India. Laisha states what the texts prescribe; it does not recommend. No quantity here is adjusted for a particular person — not for agni, koshtha, bala, age, pregnancy, kidney or liver function, or anything already being taken.

Katu and tikta with ushna virya and katu vipaka.

These are the actions the classical texts record. They are statements about what the tradition holds, and this library does not restate them as findings about a human body.

Deepyaka names the digestive action. Ugragandha, fierce-smelling, is the identifying feature and is shared with vacha, which is a reason to read a paryaya in context rather than alone.

Rasa, guna, virya, vipaka and karma are recorded as the classical texts give them, with the text and section named so a student can open the book and check. Where an exact chapter and verse could not be confirmed, this library names the section rather than inventing a number.

Ajamoda, Apium graveolens, is a different dravya with different properties, and the two names are close enough that shops and even some texts blur them. Bishop's weed seed and other small Apiaceae fruits are bulked in. The smell is the test: thymol is distinctive and a sample that does not carry it strongly is not good yavani.

Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. Carum copticum is a synonym and is the name much Ayurvedic literature uses. Not to be confused with Ajamoda, a separate dravya with a confusingly similar name, discussed below.

A WAY TO REMEMBER IT

Trachyspermum is trachys (rough) + sperma (seed) — the fruit surface is rough. Ammi is an old Greek umbellifer name.

Yavani is described in the Bhavaprakasha Nighantu and is recorded as deepana and as acting on colic. That is what the tradition holds and where it is written down, not a finding about what the fruit does in a body.

Constituents. The fruit carries an essential oil that is largely thymol, which is the source of both its smell and its strength.

Grown as a crop: how to grow ajwain, from sowing to harvest, in Laisha's grow guides.

• This is a study and clinical reference for practitioners and students. The matra and anupana it records are what the classical texts and the Ayurvedic Pharmacopoeia of India PRESCRIBE — Laisha reports them, it does not recommend them. They are not a prescription for any particular person, and they are not adjusted for your age, agni, koshtha, bala, pregnancy, kidney or liver function, or anything else you are already taking. Only a qualified practitioner who has examined you can do that.
• Traditional classification is recorded as what the classical texts say, with the text and the place in it named so it can be checked. It is not restated as a finding about a human body.
• Nothing here replaces a qualified Ayurvedic practitioner or a doctor.
