TRADITIONAL VIEW, WITH SAFETY LIMITS

Hindi name: Saunf

What the texts say Mishreya does

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

Side effects and limits

Avoid or ask first: Children under four, as regards medicinal preparations rather than a seed chewed after a meal.; Hormone-sensitive conditions, given anethole's oestrogen-like activity.; Known allergy to plants of the Apiaceae family.

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

AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

Churna1–3 g
Phanta50–100 ml
AnupanaSharkara · Ushnodaka
KalaAdhobhakta

Foeniculum vulgare. Shatapushpa is dill, a different plant, and the names are interchanged.

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.

PrabhavaThe texts treat mishreya as deepana while being sheeta, an uncommon combination, and name it for thirst and for burning as well as for digestion.

Madhura with tikta and katu, and — the examinable detail — sheeta virya despite an ushna reputation, with madhura vipaka. That is why fennel cools where ajwain heats.

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.

Upayukta angaPhala (the fruit)
Why it mattersThe dried fruit is the dravya, and it is one of the few in this library that is also chewed plain at the end of a meal across the whole country.

Paryaya

MadhurikaShatapushpaMisiShaleyaChhatra

Madhurika, the sweet one, is the paryaya that separates fennel from dill in practice — and the paryaya Shatapushpa appearing here too is exactly the source of the confusion. Shatapushpa and Mishreya are genuinely interchanged in the nighantus and in practice, and the two plants are not the same: Mishreya is Foeniculum vulgare (fennel, saunf) and Shatapushpa is Anethum graveolens (dill, soya). Both carry the paryaya Misi. This is not a tidy-up Laisha can do on the texts' behalf — it is a live ambiguity, and it matters clinically: Shatapushpa in medicinal quantity is contraindicated in pregnancy, and a reader who follows that name to the wrong plant has followed it to a different drug. Check which species a prescription or a supplier means.

Classical references

Gives the rasa, guna, virya and vipaka of mishreya.
Charaka Samhita
Sutrasthana, chapter 4 (Shadvirechanashatashritiya)

Sushruta Samhita
Sutrasthana, chapter 38 (Dravyasangrahaniya)
Included among the dravya grouped by action.

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.

Adulterants and substitutes

Dill fruit is sold as fennel and the reverse; fennel is longer, paler and sweeter. Old fruit that has lost its oil is bulked in, and coloured fennel — the bright green mouth-freshener — is dyed, sometimes with colours not permitted in food. Anise, Pimpinella anisum, is also confused with it by smell.

Identity

Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. Constantly confused with Shatapushpa, dill — the fruits look alike, and fennel is the longer, sweeter one.

A WAY TO REMEMBER IT

Foeniculum is little hay, from foenum — the dried plant smells of it. Vulgare means common.

What the tradition holds

Mishreya is described in the Bhavaprakasha Nighantu and is named among the digestive dravya. 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 anethole, which is what gives it its sweetness and is also the reason for the caution below.

What the evidence says

StatusTraditional use is extensive and long recorded. Modern clinical evidence is limited.
SuggestedHealth Canada publishes monographs covering Ayurvedic ingredients and permits specific traditional-use claims, which reflects a regulator accepting a documented tradition rather than a body of clinical trial evidence.
Not establishedThere is not enough good clinical evidence to establish an effect on any named health condition. Long traditional use is not a substitute for that evidence, and this library does not present it as one.
The honest gapPublished work uses oil or extract far more often than the fruit as chewed or infused.

Safety

Eaten daily across India with no serious harm documented at culinary use. The caution is about concentration and about infants. Fennel oil contains estragole, which regulators have assessed as genotoxic and carcinogenic in animal studies, and European regulators have restricted fennel-based preparations for young children on that basis. Fennel tea given to babies for colic is a widespread practice that the European Medicines Agency has advised against for children under four. Anethole also has oestrogen-like activity. Anyone on medication, pregnant, or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.

Side effectsAllergic reaction in those sensitive to Apiaceae
Increased sensitivity of skin to sunlight
ContraindicationsChildren under four, as regards medicinal preparations rather than a seed chewed after a meal.
Hormone-sensitive conditions, given anethole's oestrogen-like activity.
Known allergy to plants of the Apiaceae family.
InteractionsOestrogen-sensitive conditions and hormone therapy — anethole has weak oestrogenic activity.
Ciprofloxacin — fennel reduced its absorption in a study; separate the doses.
Confirm the species before acting on a prescription reading Shatapushpa or Misi: fennel and dill share those names.
Pregnancy and breastfeedingOrdinary culinary use is long established. Medicinal quantities in pregnancy or breastfeeding should be discussed with a qualified practitioner first.
Estragole, and fennel preparations for babiesFennel oil contains estragole, assessed as genotoxic and carcinogenic in animal studies. European regulators have advised against fennel-based herbal preparations in children under four. Giving fennel water to an infant for colic is common practice and is specifically what that advice concerns.

Growing it

ClimateCool season; grown through the Indian winter, chiefly in Gujarat and Rajasthan.
SoilWell-drained loam.
PlantingSown direct or transplanted.
HarvestUmbels cut as the fruit sets and turns pale green, then dried in shade so the colour and oil are kept.
What is not statedThis library has not verified region-specific spacing, variety and yield figures against a named agricultural authority for every growing country, and does not state them rather than guessing.
