Agnimantha: Traditional Uses, Evidence & Safety

TL;DR

Two plants, one name, and no human trial of the herb on its own. Two small trials have tested formulations containing it for obesity; nothing for arthritis, fever, or digestion. Agnimantha is an Ayurvedic drug name applied to Premna integrifolia and Clerodendrum phlomidis, and one of the ten roots of the classical Dashamoola group. Traditional texts reach for the root and leaves for inflammation, fever, and digestive complaints. Animal studies show genuine anti-inflammatory effects. None of it is proven in people.

What it is

Agnimantha means "fire-churner," from agni (fire) and mantha (churning): its wood was rubbed to kindle fire. A lovely etymology, and then the botany gets messy.

Classical texts recognize two types. Laghu (small) agnimantha is identified as Premna integrifolia Linn. (syn. Premna serratifolia); brihat (large) agnimantha is Clerodendrum phlomidis Linn.f. Both sit in the Lamiaceae family (Rabb review, 2022). Here is where it stops being clean. The two official references disagree with each other: the Ayurvedic Pharmacopoeia of India recognizes Clerodendrum phlomidis as Agnimantha, while the Ayurvedic Formulary of India recognizes Premna integrifolia as Agnimantha and lists C. phlomidis and Premna mucronata as its botanical substitutes (Ancient Science of Life). The confusion runs deep enough that different studies reverse the laghu and brihat labels between the two species (same study). When a label on a bottle says "agnimantha," you cannot be sure which plant is inside. I wish that were not true. It is.

Agnimantha is one of the ten roots of Dashamoola, the classical ten-root formulation group (Rabb review, 2022). Roots and leaves are the most used parts. Reported constituents include β-sitosterol and clerodin (phytochemical study), and iridoid glycosides have been reported in the wood (Rajendran & Krishnakumar).

Traditional use

Ayurveda describes the root as astringent, stimulant, carminative, and laxative, and credits it as a liver tonic and antibacterial. The indications recorded in the review literature run long: inflammation and swelling (shotha), fever, urticaria and skin eruptions, asthma, haemorrhoids, digestive weakness, worms. Leaf infusion with pepper is used for cold and fever; leaf sap for headache (Rabb review, 2022). Folk-medicine records add skin disorders, neuralgia, gonorrhoea, hyperacidity, cough, anaemia, and constipation, with warm leaf poultices applied to swellings (phytochemical study).

I will say what I say throughout this site: these are traditional claims, not clinical proof. The research record is examined separately below, and the two are not the same thing.

What modern research says

Arthritis and inflammation (animal studies)

The most direct preclinical study tested an ethanol extract of Premna serratifolia wood in rats with adjuvant-induced arthritis, a standard animal model of rheumatoid-like joint disease. The extract inhibited paw edema by 68.32% after 21 days, against 74.87% for the standard drug indomethacin, and it normalized arthritis-elevated blood markers (WBC count, ESR) (Rajendran & Krishnakumar).

That is a serious result in an animal model. My caveat is the usual one, and it matters more than the result: rats are not people, and no human trial has followed it up. The same study found no toxic symptoms or deaths in rats at acute doses up to 2000 mg/kg. An animal finding, not a human safety statement.

A comparative laboratory study of both botanical entities (root bark, roots, leaves, and flowers) reported anti-inflammatory activity for each in enzyme assays (COX-1, COX-2, 5-LOX) and in mouse macrophage cell culture (Ancient Science of Life). Separately, an alkaloid isolate (fraction F.3) from Premna serratifolia leaves showed anti-inflammatory activity in white rats with an ED50 of 5.45 mg/kg body weight (Jurnal Teknologi Laboratorium study). Consistent signals across labs. Still animals.

What the evidence does not support (yet)

No human clinical trials of agnimantha alone (for arthritis, fever, digestion, or any other indication) were identified. The only human data are two small obesity trials of multi-herb formulations containing it (see Voices). The anti-inflammatory and anti-arthritic signals come entirely from rodent studies of Premna species extracts. And the nomenclature split means some studies of "agnimantha" used Clerodendrum phlomidis material while others used Premna material, so the literature is not even always testing the same plant.

Safety & contraindications

No human safety data for agnimantha were identified. The one animal study above found no acute toxicity in rats at single doses up to 2000 mg/kg of the wood extract. An animal finding, not human safety evidence (Rajendran & Krishnakumar). There are no data on pregnancy, breastfeeding, or drug interactions. And given the botanical-identity confusion, products sold as "agnimantha" may contain either Premna or Clerodendrum material, so composition is uncertain without standardization. I do not soften any of that.

FAQs

What is agnimantha?

Agnimantha is an Ayurvedic drug name applied to two shrubs in the mint family (Lamiaceae): Premna integrifolia (laghu agnimantha) and Clerodendrum phlomidis (brihat agnimantha). It is one of the ten roots of the classical Dashamoola group (Rabb review, 2022). Buy it and you may be getting either species.

Why do sources disagree about which plant agnimantha is?

Because the two official references say different things. The Ayurvedic Pharmacopoeia of India recognizes Clerodendrum phlomidis as Agnimantha, while the Ayurvedic Formulary of India recognizes Premna integrifolia and treats C. phlomidis as a substitute. It is an unresolved nomenclature split, documented in the peer-reviewed literature, not a mistake you can clear up by reading more (Ancient Science of Life).

What is agnimantha used for in Ayurveda?

Traditional texts use the root and leaves for inflammation and swelling, fever, skin eruptions, asthma, haemorrhoids, digestive complaints, and worms (Rabb review, 2022). Traditional uses, not clinically proven effects. I keep that distinction on every page.

Does research support agnimantha for arthritis?

Only in animals. An ethanol extract of Premna serratifolia wood reduced joint swelling in arthritic rats comparably to indomethacin (Rajendran & Krishnakumar). No human trials of agnimantha for arthritis exist. That is the entire honest answer.

Is agnimantha safe?

Human safety data are lacking. One animal study found no acute toxicity at high doses, but that does not establish safety in people. Product identity is also uncertain because the name covers two different species. I would not treat either uncertainty lightly.

No established human dose exists. Without pharmacopoeial or clinical-trial dosing, no recommendation can be made. Anyone who gives you one is improvising.

The classical texts

Charaka Samhita knows agnimantha by many names: Jaya, Sriparni, Ganikarika, Jayanti, Tarkari, Nadeyi, Vaijayanti (Charak Samhita wiki entry). In Sutra Sthana chapter 4, Charaka enrolls it in two of his fifty medicinal groups: the Anuvasanopaga group (4/9(26)), which supports unctuous enema therapy, and the Shothahara group (4/9(38)), the swelling-reducers. The same entry records it as an Asthapana drug (Sutra Sthana 2/11), names it in the management of sthaulya, obesity (Sutra Sthana 21/24), and in Chikitsa Sthana 17/105 records Dashamoola kwatha (with agnimantha as one of the ten roots) for trishna, thirst, in patients of hikka-shvasa.

The nomenclature argument is itself classical. A peer-reviewed review in Ancient Science of Life notes that Charaka describes tarkari and agnimantha as distinct entities, the basis for the scholarly view that agnimantha is the Premna species and tarkari the Clerodendrum one, and confirms that Sushruta's Dashamoola group includes the name Agnimantha (full text). The split the ancients hinted at is the split the pharmacopoeias still live with.

The modern clinic

The closest thing agnimantha has to human data comes from two obesity trials at Gujarat Ayurved University, Jamnagar, published in AYU. In 2011, Ravikant Goyal, Mandip Kaur, and H. M. Chandola tested an Agnimanthadi compound (agnimantha, mustaka, and eranda patra kshara, potentiated with seven cow-urine bhavanas) against placebo in 83 enrolled obese patients (68 completed) over seven weeks. The compound group got better relief of sthaulya symptoms and statistically significant weight and BMI reduction (PMC3296348). The paper carries one line of clinical-practice honesty worth quoting: "In clinical practice it is observed that Agnimantha produces burning sensation." That is why they paired it with eranda patra kshara.

A second Jamnagar team, Ranjan K. Pattonder, H. M. Chandola, and S. N. Vyas, gave 66 registered obese patients (53 completed the course) shilajatu triturated seven times in fresh agnimantha leaf juice for ten weeks; the completers lost a mean 5.09 kg and 2.06 BMI points (P<0.001), with no adverse effects reported (PMC3361929). Small, single-center, and with no control group: interesting, not conclusive.

One caution I hold on both studies: they tested formulations, not agnimantha alone, so the herb's individual contribution cannot be isolated, and neither study touches arthritis, fever, or the other traditional indications. They are the modern voice here, and they speak to obesity, nothing more.

Sources

The botanical-identity story rests on Rabb's 2022 critical review, "Critical review on Agnimantha (Premna integrifolia Linn and Clerodendrum phlomidis Linn)," Int J Multidisciplinary Res Growth Eval. 3(4):292–298 (full text). The nomenclature split between the Ayurvedic Pharmacopoeia and the Ayurvedic Formulary is documented in the Ancient Science of Life paper on the anti-inflammatory profile of different plant parts (Ovid full text), which also reports the COX-1, COX-2, and 5-LOX assay work. The arthritis trial in rats is Rajendran and Krishnakumar's "Anti-Arthritic Activity of Premna serratifolia Linn., Wood against Adjuvant Induced Arthritis," the source of the 68.32% versus 74.87% paw-edema numbers and the 2000 mg/kg acute-toxicity finding (PMC3558150). The alkaloid-fraction ED50 of 5.45 mg/kg comes from the Jurnal Teknologi Laboratorium study on Premna serratifolia leaves (link). Folk-medicine uses and the phytochemical survey (β-sitosterol, clerodin) come from the J Chem Pharm Res investigation of Clerodendrum phlomidis root (PDF).
