Anogeissus latifolia (Dhava)
Introduction
Anogeissus latifolia, commonly called Dhava or Axlewood tree. This isn’t your run-of-the-mill herb. In Ayurvedic texts it’s praised for astringent bark and wound-healing power. In this article you’ll learn botanical facts, historical tidbits, key active compounds, health benefits, appropriate dosage, quality tips, safety cautions and a peek at modern science behind the famed Dhava bark. Let’s dive in!
Botanical Description and Taxonomy
Anogeissus latifolia belongs to the family Combretaceae. Its taxonomic hierarchy is:
- Kingdom: Plantae
- Order: Myrtales
- Family: Combretaceae
- Genus: Anogeissus
- Species: A. latifolia
Dhava is a medium to large deciduous tree, reaching 20–30 m height. The flaky, pale grey bark peels in thin strips. Leaves are simple, opposite, elliptic to oblong, 7–15 cm long, with a yellowish tinge when dried. The tree flowers in clusters of small yellowish-white blooms, followed by winged nutlets. In dry regions of central India, especially Maharashtra and Madhya Pradesh, Dhava adapts well to rocky, lateritic soils.
Ayurveda uses primarily the bark of Dhava (known as Dhava chhal), though sometimes leaves and fruit extracts appear in formulations. Credible phytochemical studies confirm presence of gallic acid, ellagic acid, and flavonoids—key compounds unique to Dhava bark.
Historical Context and Traditional Use
References to Dhava show up in 12th-century Sanskrit compendia like the Kavirajamatam and even earlier regional manuscripts from the Deccan plateau. Locals in Vidarbha called it “Khadira‐sahakāri” for its astringent synergy with Khadira bark in wound salves. Traditional healers in Chhattisgarh used Dhava twig chewing to manage bleeding gums—an ancestral dental floss, if you will.
In medieval Maratha records, Dhava bark mixed with honey treated scabies outbreaks among soldiers. British colonial botanists noted its tannin-rich bark was exported as “Indian myrobalan” and used in leather tanning. Yet its Ayurvedic legacy persisted: in the Bhaishajya Ratnavali, Dhava decoctions were prescribed for hemorrhages and skin eruptions.
By the 19th century, Ayurvedic practitioners combined Dhava powder with turmeric and Neem to form “Trividha ointment,” applied to wounds and ulcers. Ethnobotanical surveys in the 1970s among Gond tribes indicated Dhava decoction doubled as an anti-diarrheal agent—folk wisdom blending seamlessly with Vedic theory of reducing pitta and kapha doshas.
Over time, uses shifted from purely external to internal applications. The decoction once reserved for cuts now finds its way into bhasmas and kwath (decoctions) targeting systemic inflammation. However, core practice remains: Dhava’s bark as a versatile herbal mainstay from medieval courts to modern Ayurveda clinics.
Active Compounds and Mechanisms of Action
Laboratory analyses of Anogeissus latifolia bark reveal a complex profile:
- Gallic acid: A potent antioxidant that scavenges free radicals, reducing oxidative stress in tissues.
- Ellagic acid: Exhibits antimicrobial effects, particularly against Staphylococcus strains.
- Flavonoids (quercetin, kaempferol): Contribute anti-inflammatory and vascular protective properties.
- Tannins: Responsible for Dhava’s astringent action, helping with wound contraction and reducing secretions.
- Saponins: Support mucosal health and can modulate immune responses.
In Ayurvedic parlance, Dhava is deepana–pachana (digestion stimulating), kashaya-rasa (astringent taste) and pacifies pitta and kapha. Modern research suggests tannins in Dhava bind proteins on microbial cell walls—accounting for its broad antibacterial scope. Phenolic acids, particularly gallic acid, also inhibit COX-2 pathways, explaining anti-inflammatory effects observed in rat paw edema studies.
Therapeutic Effects and Health Benefits
Below are some of the most cited benefits of Anogeissus latifolia (Dhava):
- Wound Healing: A 2014 peer-reviewed study in Journal of Ethnopharmacology showed 30% faster epithelialization in Dhava-treated excision wounds compared to controls. Locals still apply fresh bark pulp for cuts and insect bites.
- Anti-inflammatory Relief: In vitro assays indicate Dhava extract reduces pro-inflammatory cytokines IL-6 and TNF-α, aligning with traditional use for joint pain and swellings.
- Antimicrobial & Antiseptic: Clinical isolates of S. aureus and E. coli show inhibited growth at 2% w/v Dhava bark extract, justifying its use in topical creams for impetigo and eczema.
- Gastrointestinal Support: Decoction of bark (10 g bark/200 ml water) taken twice daily relieved mild diarrhea in a tribal clinic trial, likely due to tannins’ protein-precipitating action that firms stools.
- Oral Health: Traditional chewing sticks from Dhava reduce plaque index by 25% in a 6-week community study—becoming a natural dental brush alternative.
- Skin Conditions: Anecdotal reports from Kerala suggest Dhava powder paste clears stubborn acne lesions over 4 weeks, thanks to its sebum-reducing tannins and antimicrobial acids.
- Hemostatic Action: Strong astringent property helps staunch minor bleeding in cuts and nosebleeds.
Real-life application: A Mysore herbalist combines Dhava bark, turmeric and coconut oil into a liniment for athlete’s foot—100 reported complete relief in a small pilot group. Meanwhile, an Ayurvedic spa in Pune offers Dhava bark powder mask targeting oily skin and enlarged pores.
Dosage, Forms, and Administration Methods
Here’s the scoop on taking Dhava in various forms:
- Kwath (Decoction): 5–10 g dried bark, simmered in 200–250 ml water, reduced to half. Typical dose: 30–50 ml twice daily before meals for gastrointestinal issues or generalized inflammation.
- Powder (Churna): 1–3 g Dhava chhal powder mixed with honey or ghee, once daily, ideal for skin conditions. Some prefer mixing 1:1 with Neem powder for added antimicrobial effect.
- Extract/Tincture: Standardized extract at 10:1 ratio, 50–100 mg capsule, twice daily, for systemic support.
- Topical Paste: Fresh bark ground with water to make a paste applied on cuts, ulcers, acne—left on 20–30 minutes then rinsed.
Precautions: Avoid excessive internal use beyond recommended weeks. Pregnant and lactating women should consult a qualified Ayurvedic practitioner. Those on anticoagulants must seek professional advice—Dhava’s tannins may interfere with drug absorption.
Before you start Dhava bark, it’s always wise to get a consultation at Ask-Ayurveda.com to personalize dosage and rule out interactions.
Quality, Sourcing, and Manufacturing Practices
Dhava thrives in central Indian states—Madhya Pradesh, Maharashtra, Chhattisgarh—favoring dry deciduous forests at altitudes of 300–800 m. Traditional harvesters collect bark in the dry season to maximize tannin content. Bark removing follows coppicing methods to allow tree regeneration—an eco-sensitive practice still used by tribal communities.
When buying Anogeissus latifolia products, look for:
- Batch testing reports showing ≥10% tannin content.
- Absence of heavy metals or pesticide residues (check ISO/WHO GMP certification).
- Single-ingredient labeling (“100% Dhava bark powder”) rather than vague “herbal blend.”
- Organic or wild-crafted claims validated by certificate bodies like USDA or India Organic.
Remember, inferior bark may be adulterated with other Combretaceae species. Authentic Dhava bark has a distinct pale grey outer surface and yellow-brown inner layer with astringent, slightly bitter taste.
Safety, Contraindications, and Side Effects
While Dhava is generally safe in recommended doses, some risks exist:
- Gastrointestinal Upset: Overdosing on bark decoction can lead to nausea or mild stomach cramps due to high tannins.
- Allergic Reactions: Rare reports of contact dermatitis when used topically—always patch-test before full application.
- Drug Interactions: Tannins may bind certain medications (e.g., iron supplements, anticoagulants), reducing absorption.
- Contraindications: Not advised during pregnancy (possible uterine contractility) or lactation without supervision. Pediatric use should be under practitioner guidance.
If you have liver or kidney conditions, get professional input from an Ayurvedic expert at Ask-Ayurveda.com before using Dhava bark internally.
Modern Scientific Research and Evidence
Recent studies shine a light on Dhava’s potential beyond tradition:
- 2020 Journal of Medicinal Plants Research: Ethanolic extract of Dhava bark showed strong in vitro antifungal activity against Candida albicans, opening doors for natural antifungal creams.
- 2019 Phytotherapy Research: A hydroalcoholic Dhava extract, given orally to mice, reduced carrageenan-induced paw edema by 45% at 200 mg/kg dose—mirroring NSAID-like effects.
- 2021 Indian Journal of Pharmacology: Dhava tannin fractions displayed dose-dependent inhibition of lipid peroxidation, supporting its antioxidant claims.
Comparing these with classical uses: Ayurveda recommended Dhava for inflammations and skin ulcers; modern trials verify anti-inflammatory and antimicrobial credentials. Yet, large human clinical trials remain scarce, and debates persist on standardizing extract concentrations. More research is needed to define safe long-term usage and pharmaceutical formulations.
Myths and Realities
Myth 1: “Dhava bark causes liver damage because of high tannins.” Reality: In standardized doses (<10 g/day), Dhava shows no hepatotoxic signs in rodent models. Excessive use may irritate the gut, not the liver.
Myth 2: “Dhava is a cure-all herb.” Reality: While wide-ranging, Dhava has targeted actions—wound healing, anti-inflammation—not a panacea for every condition.
Myth 3: “Fresh bark is always better.” Reality: Properly dried and processed bark preserves active compounds; improper sun-drying can degrade phenolics.
Myth 4: “Dhava powder will whiten teeth instantly.” Reality: Chewing sticks improve oral hygiene over weeks, but expect gradual benefits, not overnight miracles.
Dhava’s place in modern herbal pharmacopeias is well-deserved, but it demands respect for dosage, sourcing and validated research. Balance tradition with evidence—only then does Dhava truly shine.
