Synopsis

Arani (Premna serratifolia / Clerodendrum phlomidis): A Comprehensive Reference

1. Identity and Botanical Classification

1.1 Common Names and Synonyms

"Arani" (Sanskrit: अरणी) is the traditional name applied in Indian medicine to two closely related but botanically distinct plants: Premna serratifolia L. (syn. Premna integrifolia L.) and Clerodendrum phlomidis L.f. Both are known in Ayurveda as Agnimantha, a term meaning "fire-churner," a reference to the ancient use of the wood sticks to generate fire by friction. The name "Agnimantha" is composed of Agni (fire) and mantha (churning), because in ancient times the wood pieces of this plant were used to generate fire when rubbed together.

Premna serratifolia carries the Sanskrit name Agnimantha (अग्निमंथ), the Marathi and Malayalam name Arani (अरणी), the Tagalog name Alagaw, and the Visayan name Kulawin. In the Malay language it is known as malbau, and in English it is often called the "headache tree." Clerodendrum phlomidis, the second botanical source of Arani, carries the Sanskrit synonyms Agnimantha, Jaya, Shriparni, and Ganikarika, the Hindi name Arna, the Gujarati name Arani, the Tamil names Taluddai and Tazhutazhai, and the Telugu name Jayachettu. Other English common names for P. serratifolia include Coastal Premna, Agara, and Vasa.

1.2 Taxonomic Position

Clerodendrum phlomidis is a species of flowering plant in the family Lamiaceae. The plant has been used in Ayurvedic medicine, and some Ayurvedic sources refer to it by the synonym Clerodendrum multiflorum. It is a large shrub native to the Indian subcontinent and Myanmar. Premna serratifolia is likewise a species of small tree or shrub in the family Lamiaceae. The genus Premna was previously classified within the family Verbenaceae but has since been transferred into the family Lamiaceae, subfamily Viticodeae.

1.3 Botanical Debate: Dual Plant Identity

The Ayurvedic literature has long held that Agnimantha/Arani may refer to either of two species, and this ambiguity persists in modern scholarship. Classical Ayurvedic commentator Sodhala mentioned Agnimantha (Tarkari) and Arani as two different varieties, while Bhavamishra mentioned only one variety, Agnimantha, for which Tarkari is the synonym. In the Nighantu Ratnakara, Agnimantha is described as two types: laghu (smaller) and brihat (bigger). Accordingly, modern scholarship recognizes two main types: Laghu Agnimantha (Premna integrifolia) and Brihat Agnimantha (Clerodendrum phlomidis), both of which hold significance in modern and traditional medicine.

1.4 Morphology and Habitat

Premna serratifolia is a large shrub or a small tree up to 9 m in height with yellowish lenticellate bark, spinous large branches and yellowish-brown woody aromatic root; its leaves are simple, opposite, sometimes whorled, elliptic-ovate, and membranous, with 4–6 pairs of primary lateral nerves. It mostly grows in moist sandy soil and scrub jungles along seacoasts and mangrove forests. Clerodendrum phlomidis is a fairly common shrub of arid plains, low hills, and deserts of Sind, Punjab, and Baluchistan, growing 1.5–3 m tall, with ashy-grey stems and velvety branches. Its geographical distribution spans Pakistan, India, Sri Lanka, and Burma.

1.5 Common Forms and Preparations

All parts of the plant — roots, bark, leaves, stems, and flowers — carry medicinal use. The bark, roots, and leaves are used for medicinal purposes. Preparations include:

Decoction (Kadha): root boiled in water and consumed warm; powder (Churna): taken with honey, ghee, or warm water.
Ayurvedic compound preparations combining it with other Dashamoola roots; and external-use herbal pastes applied with oils.
The Ayurvedic liquid tonic Dashmoolarishta and the decoction Dasamula Kvatha, as well as the rejuvenative preparation Chyawanprash Avaleha.

2. Traditional and Historical Use

2.1 Ayurvedic Tradition (India, from the Vedic Period Onward)

Agnimantha/Arani is a very important medicinal plant described in Ayurvedic texts since the Vedic period. It is described as one of the ten herbs of Dashamoola. The Dashamoola (literally "ten roots") is a cornerstone Ayurvedic polyherbal formula. Dashamoola is an Ayurvedic polyherbal formulation prepared from ten different plant roots in equal proportions based on the traditional text Sahasrayogam; the five larger plants, called Valiyapanchamoola, include Premna integrifolia (Agnimantha), along with Stereospermum suaveolens, Aegle marmelos, Gmelina arborea, and Oroxylum indicum.

In Ayurvedic theory, Arani is principally a Vatahara (alleviating the Vata dosha, associated with the nervous and musculoskeletal system) and Shothahara (anti-edematous) drug. This herb is described as the best Vatahara and Shothahara according to Acharya Charak. Classically, it is described as treating inflammation, having hot potency, alleviating Kapha and Vata dosha, treating anemia, and having katu (pungent), tikta (bitter), kashaya (astringent), and madhura (sweet) tastes, and increasing digestive fire.

Specific traditional indications recorded in Ayurvedic texts include:

All types of Vata disorders relating to the nervous and musculoskeletal system, inflammatory disorders, neuralgia, rheumatoid arthritis, anemia, piles, constipation, common cold, and loss of appetite.
Edema (Shotha): water boiled, cooled, and mixed with the alkali of Arani (Agnimantha), with intake and local application of this preparation for three days described as alleviating edema in the abdomen.
Freckles (Vyanga): application of the paste of Arani bark pounded with goat's milk.
Anorexia: Agnimantha is described as promoting proper assimilation of food and treating heaviness in the abdomen by its deepana (appetizer and digestive) property. For obesity, it is described as having a hypolipidemic effect, improving fat metabolism, and reducing weight.
Inflammation (Shotha), diabetes (Prameha), fevers (Jwara), gonorrhoea (Upadamsha), and obesity (Sthaulya).

In traditional medicine, roots of P. integrifolia are an important ingredient of Dashmoolarishta, which is well known for reconditioning normal health of postpartum females. The root of P. integrifolia is also broadly utilized in the manufacture of Ayurvedic pharmaceutical products such as Dasamula Kvatha and Chayawanprash Avaleha.

2.2 Use in Other South and Southeast Asian Traditions

In Indo-China, the leaves and roots are used in traditional medicine as a diuretic, stomachic, and febrifuge. On Guam in the Pacific Ocean, a tea made from the boiled bark is used to treat neuralgia. The leaves of P. serratifolia are commonly consumed as a food ingredient in Tentena, Central Sulawesi, Indonesia, where the plant is known as Arogo. Premna serratifolia, known as bebuas, has long been used by the Malay community for both food and traditional medicine.

The leaves, flowers, and roots of P. serratifolia are known for their medicinal qualities in the Ayurveda, Siddha, and Unani systems of medicine. The plant is widely used in traditional medicine, particularly in Southeast Asia and India, where its leaves, roots, and bark are used to treat a variety of ailments.

3. Phytochemistry: Key Constituents and Active Compounds

3.1 Overview of Chemical Diversity

More than 250 compounds have been isolated and identified from Premna species, comprising diterpenoids, iridoid glycosides, and flavonoids as the most common secondary metabolites, followed by sesquiterpenes, lignans, phenylethanoids, megastigmanes, glyceroglycolipids, and ceramides. A 2024 comprehensive review of Clerodendrum phlomidis reported the identification of 283 compounds, including monoterpenes, sesquiterpenes, diterpenoids, flavonoids, and glycosides, which exhibit a wide range of pharmacological activities.

3.2 Diterpenoids

Diterpenoids are among the most structurally diverse and pharmacologically significant classes of compounds in Premna and Clerodendrum. Diterpenoids of the icetexane, abietane, labdane, and pimarane types can serve as useful taxonomic markers for the genus Premna. The root bark has been shown to contain a potent cytotoxic and antioxidant diterpene, 11,12,16-trihydroxy-2-oxo-5-methyl-10-demethyl-abieta-1[10],6,8,11,13-pentene.

3.3 Iridoid Glycosides

Iridoid glycosides are reported abundantly in P. serratifolia, P. subscandens, and P. microphylla. These catalpol derivatives are considered important taxonomic and pharmacological markers. Iridoid glycosides including 4″-hydroxy-E-globularinin, 10-O-trans-p-coumaroylcatalpol, premnosidic acid, and 10-O-trans-p-coumaroyl-6-O-α-l-rhamnopyranosyl catalpol have been evaluated for radical scavenging and ferric reducing antioxidant power; 4″-hydroxy-E-globularinin showed maximum radical scavenging activity, while premnosidic acid showed maximum ferric reducing ability.

3.4 Phenylethanoid Glycosides: Acteoside (Verbascoside)

Phenylethanoid glycosides (PhGs) are natural products structurally composed of a glycosidic ester consisting of cinnamic acid and hydroxyl phenylethyl moieties attached to a glycoside residue; their structure may consist of monosaccharides, disaccharides, or trisaccharides, with common glycosides being glucose, rhamnose, xylose, and apiose. They are found in many members of the family Lamiaceae, where acteoside (also called verbascoside) is common. Studies on the root wood of P. serratifolia led to the isolation of acteoside, a glucoside derivative; acteoside has been identified as the active antioxidant principle of Premna serratifolia root wood tissues.

3.5 Alkaloids

A notable alkaloid is premnazole, an isoxazole alkaloid isolated from both Premna integrifolia and Gmelina arborea. Premnazole is an isoxazole alkaloid of Premna integrifolia and Gmelina arborea with demonstrated anti-inflammatory activity. Premnazole in leaves showed significant anti-inflammatory activity in reducing cotton pellet-induced granuloma formation in rats; phytoconstituents including the isoxazole alkaloid premnazole, flavonoid luteolin, and β-sitosterol may be responsible for the observed anti-inflammatory activity profile.

3.6 Flavonoids and Steroids

Flavonoids seem to be well distributed among 16 reported Premna species despite their low number in comparison to other groups. UPLC–Q-TOF–MS/MS analysis of an aqueous root extract confirmed the presence of 12 polyphenolic compounds, including 4-hydroxy-3-methoxycinnamic acid, linarin, peonidin-3,5-O-di-beta-glucopyranoside, diosmin, trans-cinnamic acid, daidzein, saponarin, homoorietin, acacetin, sarsasapogenin, phytol, and sissotrin. Key compounds including quercetin, kaempferol, and stigmasterol exhibit diverse actions including cell cycle arrest, apoptosis induction, inhibition of metastasis, oxidative stress modulation, and autophagy.

3.7 Lignans

Two new furofuran lignans, premnadimer (1) and 4β-hydroxyasarinin-1-O-β-glucopyranoside (2), along with nine known compounds, have been isolated from the stem bark of Premna integrifolia; their chemical structures were elucidated using detailed spectroscopic studies, and their relative configurations were established using NOESY correlations.

3.8 Screening of Root Bark

Preliminary phytochemical screening of the ethanol extract of Premna serratifolia wood revealed the presence of alkaloids, steroids, flavonoids, phenolic compounds, tannins, and glycosides — specifically iridoid glycosides.

4. Scientific Evidence by Area of Use

Important note on evidence levels: All published pharmacological data for Arani/Agnimantha as of this writing derive from in vitro cell studies and in vivo animal models. The bioactive compounds responsible for the bioactivities of most plants in the genus have not been well identified, as the reported in vivo pharmacological studies were mostly carried out on crude extracts. The isolated bioactive components should be further subjected to more preclinical studies and elaborate toxicity studies before clinical trials can be pursued. No human controlled clinical trials have been published specifically on monopreparations of Arani. Evidence for the compound Dashamoola formula in postpartum recovery exists as clinical data but applies to the multi-ingredient preparation, not to Arani alone.

4.1 Anti-Inflammatory Activity

P. serratifolia reportedly possesses pharmaceutically attractive features including anti-coagulant, anti-arthritic, anti-hyperglycemic, cytotoxic, antioxidant, anti-nociceptive, gastroprotective, anti-inflammatory, and anti-microbial properties, associated with the alkaloids, iridoid glycosides, steroids, acteoside, diterpenes, and polyisoprenoids among the phytochemicals in this plant.

A key study isolated a COX-2/5-LOX dual inhibitor from Premna integrifolia extracts through bioassay-guided fractionation. Various in vivo and in vitro studies have shown cardioprotective, anti-inflammatory, immunomodulatory, anti-arthritic, anti-diabetic, anti-cancer, and hepatoprotective effects of P. integrifolia. The anti-inflammatory mechanism has been partially elucidated: premnazole in leaves showed significant anti-inflammatory activity in reducing cotton pellet-induced granuloma formation in rats; the isoxazole alkaloid premnazole, flavonoid luteolin, and β-sitosterol may be responsible for the observed activity. All studies are preclinical (animal/cell-based); no human clinical trials on anti-inflammatory outcomes from isolated Arani preparations have been published.

4.2 Anti-Arthritic Activity

A dedicated animal study published in PMC evaluated the anti-arthritic activity of ethanol extract of P. serratifolia wood using the Freund's adjuvant-induced arthritis model. The results concluded that the ethanol extract of Premna serratifolia wood at the dose of 300 mg/kg body weight displays significant anti-arthritic activity, which may be due to the presence of phytoconstituents such as alkaloids, steroids, flavonoids, phenolic compounds, and glycosides, specifically iridoid glycosides. In the indigenous system of medicine, wood of Premna serratifolia is reported to be useful in the treatment of arthritis. This is preclinical evidence only.

4.3 Antioxidant Activity

A PMC-indexed study evaluated the free radical scavenging activity of Premna serratifolia leaf; the methanolic extract was obtained by Soxhlet extraction, and superoxide radical scavenging, nitric oxide radical, hydroxyl radical, DPPH radical, ABTS radical scavenging activity, and lipid peroxidation were determined. A separate 2020 study (PMC7532407) of leaf extracts investigated antioxidant (reducing power and DNA protective) activities and enzyme inhibitory properties of water and ethanol extracts. Antioxidant activity was demonstrated for the leaves and stem bark of P. serratifolia in multiple studies. The principal antioxidant compound identified is acteoside: studies on the root wood of P. serratifolia led to the isolation of acteoside, identified as the active antioxidant principle of Premna serratifolia root wood tissues. Evidence is entirely preclinical (in vitro).

4.4 Antidiabetic / Hypoglycemic Activity

The methanolic extract of Premna integrifolia bark was subjected to antidiabetic activity investigation through oral glucose tolerance test (OGTT), normoglycemic test, and alloxan-induced diabetic test. Continuous post-treatment for 120 min showed potential hypoglycemic activity in OGTT and normoglycemic rats. At a dose of 300 mg/kg, a considerable drop in elevated blood glucose level was observed in the alloxan-induced diabetic rat after 7 days (p<0.05).

An Indonesian study (Pharmacognosy Journal, 2018) assessed the alpha-glucosidase inhibitory activity of leaf preparations. The study aimed to evaluate the α-glucosidase inhibitory and antioxidant activities of infusion and decoction of P. serratifolia leaves. In Ayurvedic traditional claims, the Agnimantha plant is described as exhibiting hypoglycemic activity and as being helpful for patients with diabetes. All antidiabetic evidence is currently preclinical; no human trials have been conducted.

4.5 Cardioprotective Activity

Extracts of P. serratifolia were found to provide protection to the heart through several mechanisms: decreasing injured cardiac marker enzymes, blood glucose, heart tissue protein, and heart tissue nucleic acids, while maintaining ECG pattern and hemodynamic changes, increasing myocardial glycogen, and restoring antioxidant status. Further investigation ruled out cardiac stimulant activities by significantly supporting positive inotropic and negative chronotropic actions similar to a β-adrenergic effect, decreasing membrane Na⁺K⁺ATPase and Mg²⁺ATPase, and increasing Ca²⁺ATPase. These are all animal-model findings. Recent laboratory research has been undertaken into the possible cardiac stimulant activity of bark and wood extracts.

4.6 Gastroprotective Activity

There was only one study reporting the gastroprotective activity of P. serratifolia leaves, conducted on aspirin-induced ulcer rats. The evaluation was carried out at doses of 200 and 400 mg/kg by looking at several parameters: lesion index, total- and free-acidity, and percentage of ulceration. This remains a single preclinical study.

4.7 Antimicrobial Activity

Several studies have shown antimicrobial properties of the ethanol extract of P. integrifolia leaves. Diterpenoids isolated from the genus have also been evaluated for antibacterial activity. Evidence is in vitro only, with no clinical antimicrobial trials published for isolated Arani preparations.

4.8 Hepatoprotective Activity

One study evaluated the hepatoprotective role of ethanol extract of P. integrifolia leaves (EEPL) on aflatoxin B1 (AFB1)-induced toxicity in mice. In silico work has helped identify candidate hepatoprotective compounds: the major compounds identified in spectrometry analysis were subjected to in silico docking against the liver enzyme alanine aminotransaminase; docking analysis validates the presence of two hepatoprotective lead compounds, stigmasterol and campesterol, which satisfy drug-likeness criteria with good absorption, distribution, metabolism, and toxicity properties. This is preclinical and computational evidence only.

4.9 Cytotoxic / Anticancer Activity

The genus Premna (Lamiaceae) is renowned for its ethnomedicinal applications including antitumor properties; despite these promising uses, the current body of literature relies predominantly on in vitro evidence, with limited knowledge regarding in vivo validation, metabolism, and bioavailability.

Preliminary cytotoxic activity of P. serratifolia leaf methanol extract has been evaluated against liver (HepG2), lung (A549), and breast (MCF7) cancer cell lines by MTT assay; alcoholic extract of leaf also exhibited significant in vitro cytotoxic activity against Ehrlich ascites carcinoma cell lines. A PMC study (PMC7865065) evaluated the cytotoxic potential of an aqueous root extract against human hepatoblastoma cancer cells (HepG2): the cytotoxic potential of aqueous extract of root of P. serratifolia against the HepG2 cell line was analysed by MTT assay, which exhibits an IC₅₀ value of 1000 µg/mL after 48 h incubation; Hoechst and AO/EtBr staining, ROS measurement, mitochondrial membrane potential, clonogenic, and wound healing assays also confirmed cytotoxic efficacy in a dose- and time-dependent manner.

Bioactivity-guided fractionation of Premna serratifolia leaves succeeded in the isolation of two terpenoids and one steroid compound with significant cytotoxic activity, representing isolation of these cytotoxic terpenoids/steroids from this plant for the first time. All cytotoxic/anticancer evidence is currently in vitro; no animal or clinical cancer studies have been published.

4.10 Anti-Obesity and Hypolipidemic Activity

Several animal studies have investigated these effects. Anti-obesity activity of a chloroform-methanol extract of Premna integrifolia in mice fed with a cafeteria diet was reported in the Journal of Pharmacy and Bioallied Sciences (2013). Hypolipidemic activity of Premna integrifolia in rats was reported in Fitoterapia (1991). All evidence is from animal models.

4.11 Enzyme Inhibition and Metabolic Potential

Different parts of P. serratifolia, including fruit, roots, bark, and leaves, have been used in folk medicine for the treatment of stomach disorders, diabetes, cough, rheumatism, inflammation, and cardiovascular disorder; pharmacological studies conducted so far confirm the ethnomedicinal uses including antioxidant, antiarthritis, antiparasitic, and cardio- and gastroprotective activities. Studies have extended investigation to antioxidant (reducing power and DNA protective) activities and enzyme (α-glucosidase, α-amylase, xanthine oxidase, and protease) inhibitory properties of water and ethanol extracts. This has direct implications for type 2 diabetes and gouty arthritis as inhibiting these enzymes is a recognized clinical approach, but all results are in vitro.

5. Body Systems and Health Areas of Association

Based on the traditional Ayurvedic literature and the available preclinical research, Arani is associated with the following body systems and health areas:

Musculoskeletal system: anti-arthritic, anti-inflammatory, analgesic; used for rheumatoid arthritis, joint pain, and Vata disorders.
Cardiovascular system: cardioprotective, cardiotonic, hypolipidemic, anti-atherosclerotic.
Metabolic/Endocrine: antidiabetic, hypoglycemic, anti-obesity.
Gastrointestinal system: gastroprotective, digestive stimulant (deepana), carminative, used for constipation, piles, and dyspepsia.
Hepatic system: hepatoprotective.
Immune system: immunomodulatory; used for infections, fever, and lymphadenitis.
Respiratory system: various parts of the plant have been employed to treat fever, inflammation, digestive disorders, and respiratory conditions.
Urinary system: Ayurvedic uses include Mutrakruccha (difficult urination) and Mutraghata (urinary retention).
Nervous system / Skin: treatment of neuralgia, headache (English common name "headache tree"), and freckles.
Oncology (preclinical only): cytotoxic activity in cell lines for liver, lung, and breast cancers.

6. Dosage Forms and Reported Dosages in Studies

No standardized clinical dosage for Arani monopreparations has been established through human trials. The following dosages appear in cited preclinical studies and traditional preparations:

Anti-arthritic study (rat model): Ethanol extract of Premna serratifolia wood at the dose of 300 mg/kg body weight displayed significant anti-arthritic activity.
Antidiabetic study (rat model): At a dose of 300 mg/kg, the methanolic extract of P. integrifolia bark produced a considerable drop in elevated blood glucose level in alloxan-induced diabetic rats after 7 days (p<0.05).
Anti-inflammatory study (rat model): Gastroprotective evaluation of leaf extract in aspirin-induced ulcer rats was carried out at doses of 200 and 400 mg/kg.
Cytotoxic study (cell line, in vitro): Aqueous root extract of P. serratifolia exhibited an IC₅₀ value of 1000 µg/mL against HepG2 hepatoblastoma cancer cells after 48 h incubation.
Anti-inflammatory study (leaf decoction, rat): Test drugs were administered orally at the dose of 9 ml/kg in a study comparing leaf decoctions of two Premna species against carrageenan-induced paw edema.
Traditional powder preparation: In traditional Ayurvedic use, the powdered root (Churna) is taken with honey, ghee, or warm water.

7. Safety Considerations

7.1 Preclinical Toxicity Data

In acute toxicity studies, the ethanol extract of Premna serratifolia did not produce any toxic symptoms or mortality up to the dose level of 2000 mg/kg body weight in rats; the extract was considered to be safe and non-toxic for further pharmacological screening.

A dedicated toxicity profiling study of the ethyl acetate extract of P. integrifolia leaves published in ScienceDirect (2021) found: single different doses (300–5000 mg/kg body weight) of extract did not show any mortality of mice; the LD₅₀ of the extract was determined to be higher than 5000 mg/kg. A separate aqueous leaf extract study yielded similar findings: the aqueous leaf extract of P. integrifolia did not show any toxicity signs at a single dose of acute toxicity up to 5000 mg/kg body weight, or at a daily dose for 28 days of sub-acute toxicity up to 1000 mg/kg body weight.

The ethyl acetate extract obtained from P. integrifolia leaves was evaluated for phenolic content and antioxidant activity; acute and subacute toxicity of the extract was studied in mice of both sexes to determine the LD₅₀ value and assess its safety profile before application as a protective agent against toxicities induced by xenobiotics.

7.2 Known Hazards

Key uses of Premna serratifolia include edible leaves and use in traditional medicine; known hazards are described as none known by Kew Garden documentation. The plant is not known to be toxic to pets or humans.

7.3 Evidence Gaps and Limitations

Many in vitro and in vivo studies have been conducted to evaluate the biological and pharmacological properties of extracts and isolated compounds of Premna species, with antimicrobial, antioxidant, anti-inflammatory, immunomodulatory, antihyperglycaemia, and cytotoxic activities demonstrated. However, the bioactive compounds responsible for the bioactivities of most plants have not been well identified, as the reported in vivo pharmacological studies were mostly carried out on crude extracts. The isolated bioactive components should be further subjected to more preclinical studies and elaborate toxicity studies before clinical trials can be pursued.

Despite promising ethnomedicinal applications, the current body of literature for the Premna serratifolia group relies predominantly on in vitro evidence, with limited knowledge regarding in vivo validation, metabolism, and bioavailability. No drug interactions have been formally characterized in human pharmacological studies. No formal reproductive toxicity, genotoxicity, or long-term chronic toxicity data have been published for isolated Arani preparations. Some plants in the same family contain iridoid glycosides and diterpenes that could theoretically modulate cytochrome P450 enzymes, but no study specific to Arani has quantified this risk in humans.

7.4 Botanical Adulteration and Substitution

The dual botanical identity of "Arani" (referring in different regions and texts to either P. serratifolia/P. integrifolia or C. phlomidis) creates a quality and identity challenge. Various source plants from the genus Clerodendrum and Premna are used in different regions of the country as Agnimantha. Pharmacognostical standardization studies have been conducted to help distinguish these species: pharmacognostical standardization on the roots of Agnimantha (Premna serratifolia L., syn. P. integrifolia L.) belonging to the family Verbenaceae — an important medicinal plant used in many Ayurvedic formulations — has been carried out in accordance with the Ayurvedic Pharmacopoeia of India protocols.
