Matra and anupana

AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

Twak churna3–6 g
Kwatha50–100 ml
Beeja churna1–3 g
AnupanaTakra · Ushnodaka
KalaAdhobhakta

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.

Pharmacopoeial standard

Ayurvedic Pharmacopoeia of India, Part I

MarkerConessine and the related steroidal alkaloids
Assay
Total ash
Acid-insoluble ash
Alcohol-soluble extractive
Water-soluble extractive
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.

Why it mattersThe bark is Kutaja and the seed is Indrayava, and the texts name them separately. A formulation calling for one does not mean the other.

Classical references

Charaka Samhita
Chikitsasthana, the chapter on atisara
Kutaja is named among the principal dravya where the bowel is loose.
Bhavaprakasha Nighantu
Guduchyadi Varga
Gives the rasa, guna, virya and vipaka of kutaja and names the seed separately.
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.

Adulterants and substitutes

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.

Identity

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.

What the tradition holds

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.

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 often does not separate bark from seed, and their alkaloid content differs several-fold.

Safety

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 effectsDigestive upset
Constipation
Bitterness and nausea
ContraindicationsPregnancy.
Use in children without a qualified practitioner.
InteractionsNo 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 breastfeedingNot to be used in pregnancy or breastfeeding.
Loose bowel is a presentation, not a diagnosisThe condition this dravya is traditionally used for can be caused by infections that require medical treatment and by fluid loss that can be dangerous quickly, particularly in children and older people. Using any herb in place of assessment and rehydration is the hazard worth naming.

Growing it

ClimateTropical, in dry and moist deciduous forest.
SoilWell-drained ground; tolerant of poor and rocky soil.
PlantingA small tree or large shrub, raised from the fine silky-tufted seed.
HarvestBark is taken in strips from part of the trunk so the tree survives. Seed is collected from the long paired pods.
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.
