TRADITIONAL VIEW, WITH SAFETY LIMITS

Hindi name: Bidarikand

What the texts say Vidari 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: Hormone-sensitive conditions, in light of the above.

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

Stands in 4 groups

A Samhita can only be read forwards, from the group to its members. This is the same list read backwards.

AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

Kanda churna3–6 g
Swarasa10–20 ml
AnupanaDugdha · Ghrita · Sharkara
KalaPragbhakta

Classical brimhana, vrishya and stanyajanana. Ipomoea digitata is sold as Bhumikushmanda in its place.

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.

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 angaKanda (the tuberous root)
Why it mattersThe large tuber is the dravya, sweet and starchy.

Swadukanda means sweet tuber and Bhumikushmanda means earth-pumpkin: both describe the large sweet root, which is how it is recognised and why it is used as a brimhana dravya.

Classical references

Charaka Samhita
Sutrasthana, chapter 4 (Shadvirechanashatashritiya)
Vidari is named among the dravya that build the body.
Bhavaprakasha Nighantu
Guduchyadi Varga
Gives the rasa, guna, virya and vipaka of vidari.
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

Ipomoea digitata, a Convolvulaceae, is sold as Vidari across much of India and is sometimes distinguished as Kshira Vidari. It is a different family with different chemistry. Because both are large starchy tubers, a dried and cut sample is very hard to tell apart, and the market treats the names as interchangeable when the plants are not.

Identity

Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. Ipomoea digitata is widely sold as Vidari and is an unrelated family; that substitution is set out below.

A WAY TO REMEMBER IT

Pueraria honours Marc Puerari. Tuberosa means bearing a tuber, which is the part used. Vidari means the one that tears, for how the tuber splits the ground.

What the tradition holds

Vidari is described in the Bhavaprakasha Nighantu and is named in the classical literature among the brimhana dravya. That is what the tradition holds and where it is written down, not a finding about what the tuber does in a body.

Constituents. The tuber carries isoflavones including puerarin and daidzein, which are phytoestrogens — plant compounds with oestrogen-like activity. That is the basis of 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 on Pueraria largely concerns Pueraria lobata, a different species used in Chinese medicine, and should not be read across.

Safety

The caution here is hormonal and specific. The tuber carries isoflavones with oestrogen-like activity, so it is not a neutral herb for anyone with a hormone-sensitive condition, and it can interact with hormonal medicines. Someone buying Vidari may well receive Ipomoea digitata instead, which has a different composition entirely. Anyone on medication, pregnant, or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.

Side effectsDigestive heaviness
Loose stool in quantity
ContraindicationsHormone-sensitive conditions, in light of the above.
InteractionsNo specific drug interaction is documented for this dravya. That is the honest state of the evidence, not a statement that none exists — most Ayurvedic dravya have never been studied for interaction. Tell the prescribing doctor it is being taken.
Oestrogen-sensitive conditions — Pueraria species carry isoflavones with oestrogenic activity.
Pregnancy and breastfeedingThere is not enough evidence to establish safety in pregnancy or breastfeeding, and a qualified practitioner should be asked first.
It carries phytoestrogensPuerarin and daidzein have oestrogen-like activity. That makes this dravya a genuine consideration for anyone with a hormone-sensitive condition, including some breast, uterine and ovarian conditions, rather than a neutral tonic.

Growing it

ClimateTropical and subtropical; a woody climber of forest and scrub.
SoilDeep, well-drained ground. A legume, so it fixes its own nitrogen.
PlantingGrown from seed or tuber pieces; needs support to climb.
HarvestTubers lifted from plants of two years or more, sliced and dried.
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.
