TRADITIONAL VIEW, WITH SAFETY LIMITS

Hindi name: Kateli

What the texts say Kantakari 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: Pregnancy.; Conditions aggravated by ushna and tikshna dravya, including acid dyspepsia.

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

Stands in 9 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

Panchanga churna3–6 g
Kwatha50–100 ml
AnupanaMadhu · Ushnodaka
KalaAdhobhakta

One of the Dashamoola; the classical kasahara of the pair with Brihati.

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.

Foreign matter

Solanum virginianum. The related Solanum species in the Brihati group carry differing alkaloid content, which is why the pair is examined together.

These are the marker and the identity test for this dravya, and they are not a test Laisha has run on anything. Laisha does not state the numeric limits here: the assay, ash and extractive figures must be read from the current edition of the Ayurvedic Pharmacopoeia of India, because a wrong limit printed here is a number a laboratory would act on. The entries in this library that DO carry figures carry them because each one was checked.

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 angaMula (the root)
Panchanga
Phala (the fruit)
Why it mattersThe root is what Dashamoola calls for. This is a Solanaceae, so the green fruit carries glycoalkaloids and that is dealt with in the safety section rather than passed over.

Paryaya

NidigdhikaKshudraVyaghriDuhsparshaKantalikaKantakarika

Kantakari means the thorny one and Duhsparsha means hard to touch: both name the prickles that cover stem and leaf. Kshudra, the small one, distinguishes it from Brihati, the large one, and the pair is always taught together.

Classical references

Sushruta Samhita
Sutrasthana, chapter 38 (Dravyasangrahaniya)
Counted among the Laghu Panchamoola, the five lesser roots of Dashamoola.
Charaka Samhita
Sutrasthana, chapter 4 (Shadvirechanashatashritiya)
Named among the dravya acting on cough and on the breath.
Bhavaprakasha Nighantu
Guduchyadi Varga
Gives the rasa, guna, virya and vipaka of kantakari.

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.

Formulations it appears in

DashamoolarishtaOne of the ten roots.
Dashamoola KwathaOne of the ten roots.
Kantakari AvalehaA linctus named for the dravya.
Vyaghri HaritakiKantakari is a principal dravya.

Adulterants and substitutes

Solanum nigrum and other small solanums are collected with it. The confusion that matters for an examination is with Brihati, Solanum indicum, which is the large one of the pair — and Brihati has its own naming problem, set out in its entry. Once roots are dried and cut the two are hard to separate, and they are in any case both in Dashamoola, so the error is usually harmless in that formulation and not harmless anywhere else.

Identity

Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. Solanum xanthocarpum and Solanum surattense are synonyms of this species and both names are common in Ayurvedic literature; they are not separate plants. One of the ten roots of Dashamoola.

A WAY TO REMEMBER IT

Solanum, solace. Virginianum is a naming accident — it is not from Virginia. Kantakari means the thorny one, which is the honest description.

What the tradition holds

Kantakari is counted among the Laghu Panchamoola and is recorded throughout the classical literature as kasahara and shwasahara. That is what the tradition holds and where it is written down, not a finding about what the plant does in a body.

Constituents. The plant carries steroidal glycoalkaloids including solasodine, along with steroidal saponins. Alkaloid content is highest in the unripe fruit.

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 rarely records which part was used, and root and fruit differ markedly in alkaloid content.

Safety

This is a nightshade and the green unripe fruit carries glycoalkaloids, which are the compounds responsible for poisoning from green potatoes. Traditional preparation uses specified parts in specified ways for that reason. It is also ushna and tikshna, so it aggravates pitta. Anyone on medication, pregnant, or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.

Side effectsBurning sensation
Digestive upset
Mouth and throat irritation
ContraindicationsPregnancy.
Conditions aggravated by ushna and tikshna dravya, including acid dyspepsia.
InteractionsAntidiabetic medicines — additive lowering reported for Solanum species.
Solasodine-type glycoalkaloids are present; the unripe fruit in quantity is a gastrointestinal irritant.
Pregnancy and breastfeedingNot to be used in pregnancy. There is not enough evidence to establish safety in breastfeeding.
Glycoalkaloids in the unripe fruitSolanum species carry steroidal glycoalkaloids, the class of compound responsible for poisoning from green potatoes. The unripe fruit carries the most. This is a property of the plant family and is stated here because a student should meet it from us.

Growing it

ClimateDry and hot; a weed of waste ground and roadsides.
SoilPoor, dry, well-drained ground.
PlantingSelf-sows from seed.
HarvestRoots lifted after fruiting, washed and dried. Fruit collected ripe where fruit is wanted.
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.
