AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

Shodhita kanda30–125 mg, specialist use only
AnupanaGhrita

Colchicine-bearing and among the upavisha. Chiefly external. A classical garbhapatani — absolutely contraindicated in pregnancy.

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 tuber), externally and only after shodhana
Why it mattersThe tuber is the article, used externally, and only after purification. Every part of the plant carries colchicine.

Paryaya

Agnishikha, flame-crest, describes the red and yellow flower. Garbhapatani — that which causes abortion — is the paryaya that records the use and the danger in one word, and it is the one a student must not forget.

Classical references

Sushruta Samhita
Kalpasthana, the chapters on poisons
Langali is described among the plant poisons with the signs of poisoning by it.
Bhavaprakasha Nighantu
Guduchyadi Varga
Gives the rasa, guna, virya and vipaka of langali and names it among the poisons.
Rasatarangini
The chapter on visha dravya
Gives the shodhana procedure for langali before any use.

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

Langalyadi TailaNamed for the dravya, used externally.
Vishagarbha TailaPurified langali is among the dravya, for external use.

Adulterants and substitutes

The tuber is V-shaped and distinctive, but dried and cut it resembles other tubers and has been mistaken for edible yam and for ativisha — both mistakes have killed people. Because colchicine is a commercially valuable compound the plant is also collected heavily for the pharmaceutical trade.

Identity

Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. Classed among the sthavara visha, and among the upavisha. The two answer different questions and are both right: sthavara visha is the ORIGIN — a poison of plant origin, against jangama, of animal origin — while upavisha is the GRADE in Rasashastra, the lesser poisons usable after shodhana, against the mahavisha. Laisha's Rasashastra manual lists it under upavisha for that reason. The state flower of Tamil Nadu and the national flower of Zimbabwe, and one of the most reliably lethal plants in India.

A WAY TO REMEMBER IT

Gloriosa means glorious, for the flame-coloured flower. Superba says it twice. Remember the pairing: the most beautiful name in the materia medica sits on one of the most lethal plants in it.

What the tradition holds

Langali is described in the Sushruta Samhita among the plant poisons and in the Bhavaprakasha Nighantu. That is what the tradition holds and where it is written down, not a finding about what the tuber does in a body.

Constituents. Every part carries colchicine and related alkaloids. Colchicine is a mitotic poison and is also a prescription medicine for gout, with a famously narrow margin between a dose that works and a dose that kills.

What the evidence says

StatusTraditional use is extensive and long recorded. Modern clinical evidence is limited.
SuggestedNo claim of established clinical effect is made here. The modern literature on this plant is almost entirely about poisoning, suicide and accidental ingestion.
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 gapColchicine content varies and is not knowable without assay.

Safety

This plant kills, slowly and without an antidote, and it is among the commonest causes of fatal plant poisoning in southern India and Sri Lanka. A single tuber can kill an adult. Colchicine poisoning is particularly cruel because it is delayed: someone may feel only vomiting and diarrhoea for hours or a day, appear to recover, and then suffer multi-organ failure and bone marrow collapse over the following days. There is no antidote. Deaths from accidental eating, from deliberate self-harm, and from mistaking the tuber for a yam are all recorded. It is used in Ayurveda externally after shodhana and is never a dravya for self-treatment in any form. Suspected poisoning is a hospital emergency even when the person looks well.

Side effectsSevere skin irritation on contact
Vomiting and diarrhoea — in this plant the first phase of poisoning, not a side effect
ContraindicationsInternal use of any kind, by anyone, in any quantity.
Self-treatment, absolutely.
Pregnancy — the paryaya Garbhapatani names why.
Breastfeeding.
Children.
InteractionsAny medicine — colchicine interacts widely and is cleared by pathways many drugs affect.
Statins — the combination raises the risk of muscle damage.
Medicines that affect the liver or kidneys.
Pregnancy and breastfeedingNot to be used in pregnancy or breastfeeding in any quantity or form.
Colchicine poisoning is delayed and usually fatalA single tuber can kill an adult. Symptoms begin as vomiting and diarrhoea, may appear to settle, and are followed over days by multi-organ failure and bone marrow suppression. There is no antidote. It is among the leading causes of fatal plant poisoning in south India and Sri Lanka.
Mistaken for edible tubersThe dried tuber has been mistaken for yam and for ativisha, and both errors have killed people.

Growing it

ClimateTropical; a climbing herb of scrub and hedges.
SoilWell-drained sandy ground.
PlantingGrown from tubers; cultivated commercially for colchicine extraction.
HarvestTubers are lifted with protection and are a poison from the moment they leave the ground.
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.
