TRADITIONAL VIEW, WITH SAFETY LIMITS

Hindi name: Makoy

What the texts say Kakamachi 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: Unripe green fruit, in any quantity.; Pregnancy, in medicinal quantity.

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

Stands in 1 group

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 swarasa10–20 ml
Kwatha50–100 ml
AnupanaUshnodaka
KalaAdhobhakta

The classical yakrit and shotha drug. Unripe berries have caused poisoning.

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 angaPanchanga (the whole plant)
Phala (the fruit)
Patra (the leaf)
Why it mattersThe leaf is eaten as a vegetable across India and the ripe fruit is eaten. The unripe green fruit is a different matter, as the safety section explains.

Paryaya

Kaka means crow and machi a fly: the small black fruits were read as crow-berries. Rasayani is the paryaya that records its standing as a rejuvenative despite being a common weed.

Classical references

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

Adulterants and substitutes

The Solanum nigrum complex contains several closely related species and they are not reliably distinguished in the field or the market. This matters because glycoalkaloid content differs between them and with ripeness, so a plant eaten safely in one district may not be the same plant in another.

Identity

Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. The Solanum nigrum complex is a group of closely related and much-confused species, and that is directly relevant to the safety of this plant.

A WAY TO REMEMBER IT

Solanum, solace. Nigrum means black, for the ripe berry. Kaka-machi means crow's grape — the same berry, named by who eats it.

What the tradition holds

Kakamachi is described in the Bhavaprakasha Nighantu and named in the classical literature as a rasayana. 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 solanine and solasonine, highest in the unripe green fruit and lowest in the ripe fruit and cooked leaf.

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 identifies which member of the species complex was used.

Safety

This plant is eaten as a vegetable by millions of people and has also poisoned people, and both facts are true because ripeness and cooking decide which. The unripe green fruit carries solanine, the compound responsible for green-potato poisoning, and children eating green berries is a recorded cause of poisoning with vomiting, drowsiness and confusion. Ripe fruit and cooked leaf carry far less. Traditional practice — cooking the leaf, eating only fully ripe fruit — is not superstition but the safety procedure. Anyone on medication, pregnant, or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.

Side effectsDigestive upset
Drowsiness
ContraindicationsUnripe green fruit, in any quantity.
Pregnancy, in medicinal quantity.
InteractionsDigoxin and cardiac glycosides — Solanum nigrum contains solanine-type glycoalkaloids and unripe berries have caused poisoning; anything affecting cardiac conduction compounds it.
Sedatives — additive CNS depression reported.
The RIPE berry is the edible one. Unripe berries are the reported poisonings.
Pregnancy and breastfeedingThe cooked leaf as food is long established. Medicinal quantities are not used in pregnancy without a qualified practitioner.
Unripe green berries poison childrenThe green unripe fruit carries solanine, the glycoalkaloid responsible for green-potato poisoning. Poisoning of children who ate green berries is recorded, with vomiting, drowsiness and confusion. Ripe fruit and cooked leaf carry far less, which is what makes the traditional preparation a safety measure rather than a custom.

Growing it

ClimateTropical and temperate; a weed of cultivated ground everywhere.
SoilAlmost any, particularly rich cultivated soil.
PlantingNot planted. It self-sows in every vegetable garden.
HarvestLeaf picked young and cooked. Fruit collected only when fully ripe and black.
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.
