Introduction
Ailanthus malabarica, often overlooked in favor of its more widely known cousins, quietly holds a niche of its own in Ayurvedic tradition and regional herbal medicine. Native to select regions of India, this lesser-known tree has been used for centuries—primarily for its bark and gum—in treating chronic fevers, digestive disturbances, and even parasitic infections. But it’s not just some random bark off a tree. There’s something intriguingly specific about the way this plant interacts with the body’s systems, particularly in older formulations passed down in palm-leaf manuscripts and regional vaidyas’ handwritten notes. In this article, we’ll walk through the botany, the actual historic records, the chemical fingerprints, and even the modern studies (limited but growing). From how the bark smells after rain to debates over its safety in long-term use, let’s look at Ailanthus malabarica as more than a name in a herb list.
Botanical Description and Taxonomy
Ailanthus malabarica, also known by local names such as "Simarouba of Malabar" or "Chhalka," is a deciduous tree that thrives in the moist, tropical slopes of the Western Ghats. Taxonomically, it falls under the family Simaroubaceae. The tree grows rapidly, reaching heights of 20 to 25 meters, and features large, compound leaves—each extending up to a meter—with 10 to 30 leaflets per frond. It bears small greenish-yellow flowers arranged in panicles, and its fruit resembles a flattened samara with a single wing, often tinged red when mature. Unlike its cousin Ailanthus excelsa, A. malabarica has thicker bark and a unique resinous aroma when bruised. Traditionally in Ayurveda, the stem bark and gum resin are the primary parts used. Compounds such as ailantone and quassinoids have been preliminarily identified in this species, though detailed phytochemical profiling remains sparse and ongoing.
Historical Context and Traditional Use
This plant's journey through Indian healing traditions is quiet but consistent. While it might not star in the Charaka Samhita or Sushruta Samhita by name, it appears more vividly in later southern compilations like the “Chikitsa Ratnakara” and Tamil palm-leaf manuscripts dating from the 18th century. In coastal Kerala, traditional vaidyas often prescribed a decoction of A. malabarica bark to treat intermittent fevers—particularly those suspected to be due to “vishamajvara” (irregular fevers akin to malaria). Interestingly, during British colonial times, botanists working under the East India Company collected samples and noted its similarity in use to Cinchona bark, the famous anti-malarial. This likely fueled some of the earlier chemical investigations into the plant.
In tribal communities of Karnataka and Maharashtra, the gum exudate is applied to snakebite wounds or consumed in minute doses for expelling intestinal worms. Unlike Ailanthus excelsa, which has been more documented in Unani and folk texts, A. malabarica is generally considered a more “restricted” remedy—used by experienced hands rather than commonly sold over the counter. It’s also been used externally, mashed with turmeric and applied to chronic skin eruptions or fungal spots, particularly during monsoon when infections peak. So, while not globally famous, this plant has sat quietly in the shadows—serving small but crucial roles.
Active Compounds and Mechanisms of Action
While research into Ailanthus malabarica isn’t yet as expansive as some better-known herbs, the chemical trail is beginning to take shape. Preliminary studies have isolated ailanthone, a bioactive quassinoid, from its bark, which shows strong antiplasmodial activity. Other compounds like malabarolides (specific to this species) and minor amounts of betulinic acid and flavonoids have also been noted. These constituents seem to exert bitter tonic effects—what Ayurvedic texts sometimes refer to as tikta rasa properties with deepana (digestive stimulant) and krimighna (anti-parasitic) effects.
Modern pharmacological analysis suggests possible anti-inflammatory and antimicrobial actions, though human trials remain extremely limited. The bitter principles might interfere with parasitic enzyme systems or act as antifeedants. Some speculation exists about its selective action on the liver and spleen, though this remains more folklore than firmly established science. Even so, its strong bitterness and bioactivity have made it a candidate for inclusion in traditional fever mixes in southern India.
Therapeutic Effects and Health Benefits
Now here’s where it gets interesting—and a bit muddy. Let’s start with the most widely accepted use: fever. Across Tamil Nadu and coastal Karnataka, the decoction of bark (boiled down with black pepper and ginger) is used for fevers that keep coming back—especially those not responding to simple remedies. This matches the ancient categorization of “vishama jwara.” The bitterness and cleansing properties also explain its use in intestinal parasitic infections—especially in children and livestock in rural areas.
Next up, skin. Some traditional healers use a paste made from the bark mixed with neem oil or turmeric for chronic eczema and scabies. It’s said to “dry out” the lesions—though it stings a bit when applied. There are anecdotal reports of its use in piles and rectal fissures, especially when combined with Triphala in decoction. In rare, more experimental practices, it’s even been tried in bronchial conditions when the cough is thick and sluggish, although most practitioners are cautious with internal use due to its intensity.
Liver support? Possibly. Some 20th-century Ayurvedic physicians noted mild improvement in jaundice symptoms when A. malabarica was used alongside Katuki or Bhumyamalaki. The rationale? Its bitter nature and ability to cleanse. There’s also talk among a few herbalists about its use in menstrual irregularities—especially where sluggish digestion is thought to be the root. But again, evidence here is patchy. It's also worth noting that practitioners often caution against long-term use due to concerns over potency, especially in weak patients. That said, in strong constitutions and with careful dosing, the herb can be quite impactful.
Dosage, Forms, and Administration Methods
Traditional use of Ailanthus malabarica is usually bark-focused, with preparations mostly limited to decoctions (kashayam), powders (churna), and occasionally semi-solid pastes (lepa) for topical application. The standard dosage for a bark decoction is around 50–75 ml per day, split into two doses, generally taken after meals. Preparation involves boiling 5–10 grams of coarse bark in 200 ml of water until it reduces to one-fourth. Some practitioners enhance the decoction’s potency with ginger or long pepper, especially for fever-related complaints.
Powdered bark is less commonly used but may be given in doses of 250–500 mg, once or twice daily, often mixed with honey or ghee depending on the patient’s prakriti. External paste preparations usually mix fresh bark with turmeric or neem extract and are applied once daily for skin disorders.
For children or elderly patients, dosage should be adjusted cautiously—usually halved—and only under close supervision. Pregnant or lactating women are advised to avoid Ailanthus malabarica altogether due to the bitter and potentially emmenagogue nature of its compounds. It's also best avoided in debilitated individuals unless explicitly recommended.

Quality, Sourcing, and Manufacturing Practices
Ailanthus malabarica is primarily found in the Western Ghats, particularly in the Malabar, Coorg, and Konkan regions, where the climate—warm, humid, and monsoon-heavy—supports its optimal growth. Traditionally, bark is harvested from mature trees aged 8–12 years during late winter, when the plant sap is stable and bioactive content is said to peak.
While there’s no widespread commercial cultivation, some small-scale forest cooperatives in Kerala and Karnataka harvest it sustainably. Authenticity can be tricky, as it's sometimes confused with Ailanthus excelsa or even Simarouba glauca. Buyers should look for a deep reddish-brown bark with a bitter taste and mild resinous smell—distinct markers of A. malabarica.
When purchasing, check for batch-wise certifications, ethnobotanical source details, and absence of contaminants or heavy metals. Opt for trusted Ayurvedic pharmacies or verified online sellers with proper labelling.
Safety, Contraindications, and Side Effects
Despite its efficacy, Ailanthus malabarica is not without risk. Due to its strong bitterness and complex phytochemistry, gastrointestinal irritation (nausea, cramping) can occur if overdosed. Individuals with ulcers, IBS, or sensitive digestion should avoid it. Traditional texts also hint at its tikshna (sharp) quality—suggesting that it can aggravate pitta when misused.
Documented contraindications include:
-
Pregnancy and lactation
-
Children under 5
-
Patients with liver failure or autoimmune conditions
-
Concurrent use of strong anticoagulants or corticosteroids
There’s some anecdotal mention of allergic rashes when the paste is applied topically—usually in those with hypersensitive skin. Always do a patch test if applying externally.
And just to reiterate: consult a qualified practitioner. This isn’t a “self-care” herb—it demands supervision and respect.
Modern Scientific Research and Evidence
Unfortunately, robust modern studies on Ailanthus malabarica are limited. A handful of pharmacognostic studies published between 2005 and 2019 in journals like Ancient Science of Life and Pharmacognosy Research highlight its antimicrobial and antiparasitic potential—particularly against Plasmodium falciparum and Staphylococcus aureus. These findings correlate with its traditional use in malaria and skin infections.
A 2011 study from the University of Kerala suggested the presence of quassinoids with promising cytotoxic activity, although this has not progressed to clinical trials. Another lab-based investigation hinted at hepatoprotective potential when used in polyherbal combinations, though the data remains inconclusive.
There’s growing interest in comparing its effects to more widely studied Simarouba species, especially since both share bitter principles. However, data is patchy, and many assumptions about its efficacy are still drawn from field experience rather than formal trials.
Still, it's a plant to watch—there’s room for discovery, and traditional healers seem to know more than the labs have caught up with yet.
