One name, more than one plant
Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. Premna integrifolia and Premna obtusifolia are treated as synonyms. In parts of India Clerodendrum phlomidis is used under this name, and that is set out below. One of the ten roots of Dashamoola, counted among the five great roots.
TRADITIONAL VIEW, WITH SAFETY LIMITS
Hindi name: Arni
What the texts say Agnimantha 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
| Kwatha | 50–100 ml |
| Churna | 3–6 g |
| Anupana | Ushnodaka |
| Kala | Adhobhakta |
One of the Dashamoola; the root bark is the part used.
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.

Premna serratifolia and Clerodendrum phlomidis are both used as Agnimantha with regional authority. The species must be named before a figure means anything.
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 | TiktaKatuKashayaMadhura |
| Guna | LaghuRuksha |
| Virya | Ushna |
| Vipaka | Katu |
| Prabhava | The texts treat it as shothahara, acting on swelling, and it is named in that connection more than any other member of the great five. |
| Doshakarma | Kaphavatahara. Being ushna it increases pitta. |
Four rasa, with ushna virya and katu vipaka.
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) |
| Why it matters | The root is what Dashamoola calls for. |
Agnimantha means fire-churner: the wood was used as the drill for kindling the sacrificial fire, and the name records a use that has nothing to do with medicine. Vahnimantha says the same thing another way.

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. |
| Dashamoola Taila | One of the ten roots. |
| Chyawanprash | Among the dravya of the formulation. |
Two plants are used as Agnimantha across India: Premna serratifolia and Clerodendrum phlomidis, which the texts and later commentators distinguish as the large and the small kind. Both usages are old and neither is a fraud. As with Prishniparni, a Dashamoola preparation from one region may not contain the same plant as one from another, and a student is expected to know that rather than be surprised by it.
Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. Premna integrifolia and Premna obtusifolia are treated as synonyms.

A WAY TO REMEMBER IT
Premna from Greek premnon, a tree stump — the genus was named for its short, thick trunk. Serratifolia is serrated leaf. Agnimantha means fire-churner: its wood was used to make the ritual fire by friction.
Agnimantha is counted among the Brihat Panchamoola in the Sushruta Samhita and is recorded as shothahara. 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 root and bark carry iridoid glycosides and alkaloids including premnine. Composition differs between the two plants used under this name.
| 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 frequently does not say which of the two plants was used. |
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 ushna and aggravates pitta, and 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 Burning sensation in those of pitta constitution |
| 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, including coastal scrub. |
| Soil | Wide range, tolerant of poor and saline ground. |
| Planting | A shrub or small tree, grown from seed or cuttings. |
| Harvest | Roots lifted from established plants, washed, cut and dried in shade. |
| What is not stated | Most supply is collected from the wild and Dashamoola demand is heavy, which is a pressure on wild stands. |
