One name, more than one plant

TRADITIONAL VIEW, WITH SAFETY LIMITS

What the texts say Karanja does

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

AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

Beeja churna1–3 g
Twak kwatha50–100 ml
AnupanaUshnodaka · Takra
KalaAdhobhakta

Chiefly external in kushtha; the oil is the usual form and is not for internal use.

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 angaBeeja (the seed)
Beeja taila (the seed oil)
Mula twak (the root bark)
Patra (the leaf)
Why it mattersThe seed oil is the dravya most used and is applied externally. The oil is bitter and foul-smelling, which is not a fault but the article.

Naktamala means night-garland, from the dense flowering. Chirabilva records that it grows along water, like bilva.

Classical references

Charaka Samhita
Sutrasthana, chapter 4 (Shadvirechanashatashritiya)
Karanja is named among the dravya of the chapter.
Bhavaprakasha Nighantu
Guduchyadi Varga
Gives the rasa, guna, virya and vipaka of karanja.
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.

Formulations it appears in

Karanja TailaAn oil named for the dravya, used externally.
Kaishora GugguluAmong the dravya of the formulation.
Karanjadi KwathaNamed for the dravya.

Adulterants and substitutes

Karanja oil is now a commodity for biodiesel and for soap, and industrial-grade oil — extracted with solvent rather than pressed — is sold where the medicinal grade is meant. Caesalpinia bonduc is called Lata Karanja and Holoptelea integrifolia is called Chirabilva, both of which share paryaya with this tree and are different plants.

Identity

Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. Pongamia pinnata and Derris indica are synonyms, and Pongamia is the name most Ayurvedic and most agricultural literature uses. The same tree is now grown widely for biodiesel.

A WAY TO REMEMBER IT

Millettia honours Charles Millett. Pinnata means the leaf is pinnate, in pairs along a stalk.

What the tradition holds

Karanja is described in the Bhavaprakasha Nighantu and is named among the dravya for the skin. That is what the tradition holds and where it is written down, not a finding about what the oil does in a body.

Constituents. The seed carries flavonoids including karanjin and pongamol, and a fixed oil that is bitter and non-edible.

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 mostly concerns the oil as a fuel or a pesticide rather than as the tradition uses it.

Safety

The oil is used externally and that is how the tradition uses it. It is not an edible oil and should not be treated as one — it is bitter, it is used as a pesticide, and karanjin is toxic to fish and insects. Taken internally without direction it causes vomiting and digestive upset, and poisoning from the seed is recorded. Solvent-extracted industrial oil is a different article from cold-pressed and is not intended for the body. Anyone on medication, pregnant, or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.

Side effectsSkin irritation on external use in some people
Nausea and vomiting if swallowed
ContraindicationsInternal use without a qualified practitioner.
Pregnancy and breastfeeding.
Children.
InteractionsNo specific interaction is documented here. Anyone on regular medication should still tell their doctor what they are taking.
Pregnancy and breastfeedingNot to be used in pregnancy or breastfeeding.
It is not an edible oilKaranja oil is non-edible, is used as a pesticide, and poisoning from the seed is recorded with vomiting and gastrointestinal upset. It is used externally in the tradition and internal use belongs only with a qualified practitioner.

Growing it

ClimateTropical; common along watercourses and planted as an avenue tree.
SoilWide range including saline and waterlogged ground. A legume, so it fixes nitrogen.
PlantingA tree, raised from seed. Now planted at scale for biodiesel.
HarvestPods collected when ripe and the seed pressed for oil.
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.
