TRADITIONAL VIEW, WITH SAFETY LIMITS
Hindi name: Kurchi
What the texts say Kutaja 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.; Use in children without a qualified practitioner.
A traditional classification, not a recommendation. The full safety record is below.
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
| Twak churna | 3–6 g |
| Kwatha | 50–100 ml |
| Beeja churna | 1–3 g |
| Anupana | Takra · Ushnodaka |
| Kala | Adhobhakta |
Takra is the classical anupana in atisara and pravahika. Bark and seed (Indrayava) are distinct drugs.
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 |
Conessine in the bark of Holarrhena pubescens. Wrightia tinctoria is the standing substitute and carries none.
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.

| Prabhava | Kutaja is the dravya the classical literature names first for atisara and pravahika, and the old botanical name antidysenterica records how firmly that association was held. |
| Doshakarma | Kaphapittahara. Being ruksha and sheeta it can increase vata. |
Tikta and kashaya with sheeta virya and katu vipaka — the profile the texts associate with its action on the bowel.
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 anga | Twak (the stem bark) Beeja (the seed), as the separate dravya Indrayava |
| Why it matters | The bark is Kutaja and the seed is Indrayava, and the texts name them separately. A formulation calling for one does not mean the other. |
Kalinga records the country. Girimallika, hill jasmine, describes the white flowers, which is how the tree is spotted on a hillside in the rains.

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.
| Kutajarishta | A fermented preparation named for the dravya. |
| Kutajavaleha | A linctus named for the dravya. |
| Kutaja Ghana Vati | Named for the dravya. |
Wrightia tinctoria is the classic substitute and grows in the same places with similar white flowers and similar long paired pods. The distinction taught in the field is taste: kutaja bark and seed are markedly bitter and Wrightia is not, which is why the Urdu name for the seed is inderjo talkh, the bitter indrayava, against inderjo shirin, the sweet one, which is the substitute.
Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. Holarrhena antidysenterica is a synonym and is the name most Ayurvedic literature uses. The seed, Indrayava, is treated as a separate dravya from the bark.
A WAY TO REMEMBER IT
Holarrhena is holos (whole) + arrhen (male) — the anthers run the whole length. Pubescens means downy. Kutaja means born of a mountain rock.
Kutaja is named in the Charaka Samhita among the dravya used where the bowel is loose, and is described in the Bhavaprakasha Nighantu. That is what the tradition holds and where it is written down, not a finding about what the bark does in a body.
Constituents. The bark and seed carry steroidal alkaloids, of which conessine is the principal one. Alkaloid content is much higher in the bark than in the seed.
| Status | Traditional use is extensive and long recorded. Modern clinical evidence is limited. |
| Suggested | Health 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 established | There 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 gap | Published work often does not separate bark from seed, and their alkaloid content differs several-fold. |
This is a dravya of the Apocynaceae, a family rich in potent alkaloids, and it is not a gentle herb. Conessine in quantity is documented to act on the nervous system. It is used where the bowel is loose, which is a presentation that can itself be serious — dysentery in a child or an older person needs a doctor, and reaching for a herb instead of fluids and diagnosis is the real danger here. Anyone on medication, pregnant, or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.
| Side effects | Digestive upset Constipation Bitterness and nausea |
| Contraindications | Pregnancy. Use in children without a qualified practitioner. |
| Interactions | No specific drug interaction is documented. The conantokin-type alkaloids of the seed have not been studied for interaction, which is a gap and is stated as one. |
| Pregnancy and breastfeeding | Not to be used in pregnancy or breastfeeding. |
| Climate | Tropical, in dry and moist deciduous forest. |
| Soil | Well-drained ground; tolerant of poor and rocky soil. |
| Planting | A small tree or large shrub, raised from the fine silky-tufted seed. |
| Harvest | Bark is taken in strips from part of the trunk so the tree survives. Seed is collected from the long paired pods. |
| What is not stated | This 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. |
