Dhava: Benefits, Evidence & Safety

TL;DR

Dhava (Anogeissus latifolia) is an Ayurvedic tree whose tannin-rich bark is traditionally used for wounds, urinary disorders, piles, skin conditions, and diabetes. Animal studies suggest kidney-protective, liver-protective, and wound-healing effects, but no human trials exist. Its gum (ghatti gum) is a widely used food and pharmaceutical excipient. Evidence for medicinal benefits is preliminary: traditional use is not clinical proof.

What it is

Dhava (also called Dhaura or axle-wood tree) is Anogeissus latifolia (Roxb. ex DC.) Wall., a medium to large deciduous tree in the Combretaceae family found across India's deciduous forests. The stem bark, rich in tannins, ellagic acid, gallic acid, and flavonoids, is the principal medicinal part, while the tree's exuded gum, known as ghatti gum (Indian gum), is used commercially as an emulsifier and binding agent in foods and pharmaceuticals.

Traditional use

Dhava has deep classical roots: Sushruta groups it in the Salasaradi and Muskakadi ganas, Vagbhata in the Asanadi gana, and later nighantus (Bhavaprakasha, Kaiyadeva, Raja Nighantu) classify it among astringent, wound-healing drugs. (Botanical, chemical and pharmacological review of Dhava, IJPR Applications, 2025) The stem bark is traditionally used for asmari (urinary calculus), arsa (piles), mutrakrcchra (dysuria), kustha (skin diseases), prameha (urinary/metabolic disorders), pandu (anemia), wounds and ulcers, diarrhea, and bleeding disorders. (Nephroprotective study introduction, Journal of Ethnopharmacology, 2021) Externally, bark paste is applied to wounds and localized swelling. These are traditional uses, not clinical proof of efficacy.

What modern research says

Published pharmacological work on Anogeissus latifolia is preclinical: animal or laboratory studies, with no human randomized trials found.

Kidney protection (animal studies)

An ethanolic extract of A. latifolia stem bark was evaluated against gentamicin-induced nephrotoxicity in rats, a standard animal model of drug-induced kidney injury, based on the bark's traditional use in urinary and kidney disorders. (Nephroprotective potential of Anogeissus latifolia, Journal of Ethnopharmacology, 2021) The finding is animal-only and does not establish kidney benefits in humans.

Liver protection, antioxidant, and anti-ulcer effects (animal and laboratory studies)

Prior studies summarized in the peer-reviewed literature report hepatoprotective, antioxidant, anti-ulcer, and antibacterial activities of the stem bark in animal and in-vitro models. (Nephroprotective study introduction, Journal of Ethnopharmacology, 2021; Discover Plants review, Springer, 2025)

Wound healing (traditional and preclinical)

Dhava bark is traditionally applied as a paste to wounds and ulcers, and pharmacological reviews note wound-healing potential among its reported activities: attributed in part to its high tannin content, which is astringent and antimicrobial in the laboratory. (Dhava botanical/chemical/pharmacological review, IJPR Applications, 2025) Clinical evidence for wound healing in humans is lacking.

Blood sugar effects (animal studies)

Some animal studies suggest the plant's extracts may help manage blood glucose, but the evidence is preliminary and inconsistent. (Dhava botanical/chemical/pharmacological review, IJPR Applications, 2025) There is no human evidence supporting Dhava for diabetes.

Safety & contraindications

No human safety trials of Dhava bark were found in the peer-reviewed literature, so safety data is limited: talk to a clinician before use. One reassuring context point: the tree's gum (ghatti gum) is an established food and pharmaceutical excipient, but that says nothing about the safety of concentrated bark extracts or decoctions. Because the bark is strongly astringent (tannin-rich), traditional sources advise care in people prone to constipation, and internal use during pregnancy or alongside regular medicines should only happen under qualified guidance.

FAQs

What is Dhava?

Dhava is Anogeissus latifolia (Roxb. ex DC.) Wall., a deciduous tree of the Combretaceae family native to Indian forests, known in English as axle-wood or the ghatti tree. Its tannin-rich stem bark is the main Ayurvedic drug, and its exuded gum, ghatti gum, is used in the food and pharmaceutical industries. (Discover Plants review, Springer, 2025)

What is Dhava used for in Ayurveda?

Classically, the bark is used for urinary disorders (including stones and painful urination), piles, skin diseases, wounds and ulcers, diarrhea, bleeding disorders, anemia, and diabetes-related conditions. (Journal of Ethnopharmacology, 2021) These are traditional indications: modern evidence for them is limited to animal and laboratory studies.

Does research support Dhava for kidney health?

Only in animals. An ethanolic bark extract was tested against gentamicin-induced kidney injury in rats, motivated by the bark's traditional use in urinary disorders. (Journal of Ethnopharmacology, 2021) No human studies exist, so this cannot be taken as evidence that Dhava protects or treats kidneys in people.

What is ghatti gum?

Ghatti gum (Indian gum) is the natural exudate of the Dhava tree: a high-molecular-weight polysaccharide used as an emulsifier, stabilizer, and binding agent in foods, confectionery, and pharmaceutical preparations, often as an alternative to gum arabic. (Discover Plants review, Springer, 2025) It is distinct from the medicinal bark preparations.

Can Dhava help with diabetes?

There is no human evidence. A few animal studies suggest possible blood-glucose effects, but the data are preliminary and inconsistent. (Dhava review, IJPR Applications, 2025) Dhava should not be used as a diabetes treatment or as a substitute for prescribed medication.

Is Dhava safe?

Safety data is limited: talk to a clinician. No published human safety trials were found. While its gum is a common food additive, concentrated bark extracts have not been safety-tested in people. Traditional sources advise caution in constipation (the bark is strongly astringent), and pregnant or medicated individuals should seek qualified guidance before use.
