TRADITIONAL VIEW, WITH SAFETY LIMITS
What the texts say Gambhari 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: No absolute contraindication is documented here. This is written deliberately rather than left blank.
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 kwatha | 50–100 ml |
| Churna | 3–6 g |
| Anupana | Ushnodaka · Madhu |
| Kala | Adhobhakta |
One of the Dashamoola.
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 |
Gmelina arborea root. One of the Dashamula and among the more reliably supplied of them.
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.
| Rasa | TiktaKashayaMadhura |
| Guna | Guru |
| Virya | Ushna |
| Vipaka | Katu |
| Prabhava | The texts single out the fruit as a rasayana and as hridya, and treat the root and the fruit as almost separate dravya. |
| Doshakarma | Tridoshahara. |
Tikta and kashaya with madhura, ushna virya and katu vipaka. The fruit is madhura with sheeta virya and is treated separately.
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 | Mula (the root) Mula twak (the root bark) Phala (the fruit) |
| Why it matters | The root is what Dashamoola calls for. The ripe fruit is a separate dravya and is described in the texts as madhura and sheeta, quite unlike the root. |
Kashmari and Shriparni are the paryaya most used in the texts. Madhuparnika, sweet-leaved, points to the fruit rather than the root, and a student should notice that the paryaya of this dravya do not all describe the same part.

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.
| Dashamoolarishta | One of the ten roots. |
| Dashamoola Kwatha | One of the ten roots. |
| Chyawanprash | Among the dravya of the formulation. |
| Dashamoola Taila | One of the ten roots. |
Because the tree is planted commercially for timber, root material is more often genuine than for the other great roots. The substitution that occurs is stem bark or wood in place of root, since a timber plantation produces those in quantity and the root only when a tree is grubbed out.
Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. One of the ten roots of Dashamoola, counted among the five great roots. The same tree is planted widely as a fast-growing timber crop, which is why it is easier to get honestly than most Dashamoola members.
A WAY TO REMEMBER IT
Gmelina honours Johann Georg Gmelin. Arborea simply means tree-like.
Gambhari is counted among the Brihat Panchamoola in the Sushruta Samhita and the fruit is recorded as a rasayana. That is what the tradition holds and where it is written down, not a finding about what the tree does in a body.
Constituents. The root and bark carry lignans including gmelinol, along with iridoid glycosides. Content differs between root, bark and fruit.
| 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 rarely separates root from bark or fruit, and the tradition treats them as different dravya. |
No serious harm is documented for this dravya at traditional use, which is a statement about the absence of records and not a guarantee. It is almost always used as one of ten roots rather than alone. Anyone on medication, pregnant, or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.
| Side effects | Digestive upset |
| Contraindications | No absolute contraindication is documented here. This is written deliberately rather than left blank. |
| Interactions | No specific interaction is documented here. Anyone on regular medication should still tell their doctor what they are taking. |
| Pregnancy and breastfeeding | There is not enough evidence to establish safety in pregnancy or breastfeeding, and a qualified practitioner should be asked first. |
| Climate | Tropical, in moist deciduous forest; also planted widely as a timber crop. |
| Soil | Deep, well-drained, moist ground. Grows fast where it is suited. |
| Planting | A tree, raised from seed or by stump planting. Among the fastest-growing hardwoods in India. |
| Harvest | Root and root bark are taken when trees are grubbed out, which is the honest source. Fruit is collected ripe. |
| 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. |
