Health Benefits
**Anti-inflammatory Activity**
The stilbenoid oxyresveratrol and prenylated flavonoids in the bark and heartwood suppress arachidonic acid cascade signaling, reducing pro-inflammatory eicosanoid production relevant to wound healing applications documented in Thai ethnomedicine.
**Antioxidant Defense Upregulation**
Bark and leaf extracts activate the Nrf2 transcription factor at concentrations as low as 5 µg/mL, increasing expression of cytoprotective enzymes NQO1 and HO-1 that neutralize reactive oxygen species.
**Wound Healing Support**
Traditional Thai medicine employs bark and heartwood preparations topically for wound management, a use supported by demonstrated antimicrobial activity against skin-relevant pathogens in laboratory susceptibility testing.
**Anti-melanogenic Properties**
Oxyresveratrol from the heartwood inhibits tyrosinase enzyme activity, the rate-limiting step in melanin biosynthesis, making it relevant to hyperpigmentation management in topical cosmetic formulations.
**Antimicrobial Activity**
Ethanolic and methanolic extracts from multiple plant parts have demonstrated inhibitory activity against bacterial and fungal pathogens in disc-diffusion and MIC assays, with the bark showing particularly broad-spectrum activity.
**Hepatoprotective Potential**
Triterpenoids including lupeol and lupeol acetate identified in the bark are associated with mitochondrial protection and redox modulation, paralleling hepatoprotective mechanisms documented for these compound classes in other botanical sources.
**Nutritional Antioxidant Contribution**: The fruit provides vitamin C (~13
4 mg per 100 g) alongside phenolic compounds, offering modest dietary antioxidant intake when consumed fresh as part of traditional Southeast Asian diets.
Origin & History
Natural habitat
Artocarpus lakoocha Roxb. is native to South and Southeast Asia, distributed across India, Thailand, Myanmar, Malaysia, and parts of Indonesia, where it grows in tropical lowland and monsoon forests up to approximately 1,000 meters elevation. The tree thrives in well-drained, fertile soils with high humidity and is commonly found along riverbanks and in mixed deciduous forests. In Thailand, India, and Myanmar it has been cultivated semi-domestically near villages for both food and medicinal purposes for centuries.
“Artocarpus lakoocha, commonly called monkey jackfruit or Lakoocha, has been documented in Thai, Ayurvedic, and Burmese traditional medicine systems for centuries, where the bark and heartwood were employed as astringents and anti-inflammatory agents for skin wounds, dermatitis, and febrile conditions. In Thai traditional medicine, the heartwood decoction was specifically applied topically for wound healing and as an antifungal preparation, with its reddish heartwood recognized as the medicinally potent part of the tree. The fruit has longstanding culinary use across India, Thailand, and Myanmar, eaten fresh or pickled, and its seeds are occasionally used as food after cooking. Regional vernacular names including 'Lakoocha' (Bengali/Hindi), 'Phak khanun' variations (Thai), and 'Monkey Jack' (English colonial nomenclature) reflect its wide ethnobotanical recognition across diverse cultural systems.”Traditional Medicine
Scientific Research
The available evidence base for Artocarpus lakoocha consists entirely of in vitro phytochemical screening, antioxidant capacity assays (DPPH and CUPRAC methods), antimicrobial susceptibility testing, and cell-based mechanistic studies; no published human clinical trials with defined sample sizes or effect sizes have been identified as of the current literature review. Antioxidant studies quantify bark extract capacity at 7.19±0.10 mg AEAC/g by DPPH and 91.32±3.77 mg AEAC/g by CUPRAC, providing reproducible in vitro benchmarks but not translatable therapeutic doses. Mechanistic cell studies documenting Nrf2, HO-1, and NQO1 expression changes are rigorous at the in vitro level but have not been replicated in animal pharmacology models with full dose-response characterization for most endpoints. The overall evidence quality is preclinical and exploratory, placing this ingredient firmly in a hypothesis-generating phase; well-designed animal studies followed by Phase I human safety trials are needed before any evidence-based clinical recommendation can be issued.
Preparation & Dosage
Traditional preparation
**Traditional Topical Preparation (Bark Poultice)**
Powdered or macerated bark of A. lakoocha applied directly to wounds or inflamed skin as a paste; no standardized concentration or duration established.
**Ethanolic Bark Extract (Research Grade)**
Laboratory studies employ 70–95% ethanol extraction; no standardized human supplemental dose has been established from clinical data.
**Methanolic Leaf Extract**
Used in antimicrobial and antioxidant assays at test concentrations of 1–20 µg/mL in cell studies; direct translation to oral or topical human doses is not yet validated.
**Fresh Fruit (Dietary)**
4 mg vitamin C per 100 g and dietary fiber (~2
Consumed fresh in Southeast Asian diets; nutritional contribution includes ~13..47%), but no therapeutic dosing applies.
**Cosmetic/Topical Oxyresveratrol Standardized Extract**
Emerging use in skin-lightening formulations; oxyresveratrol concentrations used in cosmetic research typically range from 0.1–1% w/v in topical vehicles, though no regulatory standardization exists.
**Dosage Note**
No evidence-based supplemental dose range, bioavailability parameter, or standardization percentage (e.g., % oxyresveratrol) has been established for oral human use; all dose extrapolation from in vitro data remains speculative.
Nutritional Profile
The fruit of A. lakoocha contains approximately 75.5% moisture, 0.24% protein, 0.63% fat, and 2.47% crude dietary fiber per 100 g fresh weight, making it a low-calorie fruit with modest macronutrient density. Vitamin C content is approximately 13.4 mg per 100 g, providing a minor but meaningful dietary antioxidant contribution. The bark is the richest source of total phenols (10.14±0.72 g GAE per 100 g), while leaves carry the highest flavonoid content (17.13±1.77 g QE per 100 g), concentrations that far exceed the fruit and reflect the medicinal parts' phytochemical density. Key identified phytochemicals include oxyresveratrol, artocarpesin, catechin, moracin, cyclocommunin, lakoochanone, lakoochanosides, lupeol, and lupeol acetate; bioavailability of these compounds from oral consumption has not been characterized in human pharmacokinetic studies, and the matrix effects of traditional preparation methods on compound stability and absorption remain unknown.
How It Works
Mechanism of Action
Oxyresveratrol (ORV), the predominant stilbenoid in the heartwood, exerts anti-inflammatory effects by inhibiting cyclooxygenase and lipoxygenase enzymes within the arachidonic acid pathway, reducing prostaglandin and leukotriene synthesis. Concurrently, A. lakoocha extracts activate the Nrf2-Keap1 signaling axis: at 5 µg/mL, Nrf2 protein expression increases, driving transcription of phase-II antioxidant enzymes including NQO1 (upregulated across 1–20 µg/mL) and HO-1 (upregulated from 10 µg/mL), which collectively detoxify electrophiles and reduce oxidative stress burden. Oxyresveratrol additionally inhibits tyrosinase through competitive or mixed-mode enzyme inhibition, blocking the hydroxylation of L-tyrosine to L-DOPA and subsequent melanin polymerization. Lupeol and lupeol acetate triterpenoids contribute mitochondrial membrane stabilization and redox modulation, potentially synergizing with the stilbenoid fraction to produce the observed cytoprotective phenotype in cell-based assays.
Clinical Evidence
No human clinical trials investigating Artocarpus lakoocha as a therapeutic or nutraceutical intervention have been published in the peer-reviewed literature available to date. All mechanistic and efficacy data derive from in vitro cell culture experiments and phytochemical characterization studies, which, while methodologically sound, cannot establish human pharmacokinetics, effective doses, or clinical outcomes. The absence of animal pharmacology studies with full ADME profiling represents an additional evidence gap that precedes any ethical pathway to human trials. Confidence in clinical benefit claims must therefore be rated as low; traditional ethnomedicinal use in Thai and South Asian contexts provides contextual plausibility but does not substitute for controlled clinical evidence.
Safety & Interactions
Comprehensive human safety data, including adverse effect profiles, maximum tolerated doses, and formal drug interaction studies, are absent from the published literature for Artocarpus lakoocha in any form. No regulatory body has established an acceptable daily intake or tolerable upper limit for bark, leaf, or heartwood extracts; consumption of the fresh fruit at normal dietary quantities is generally regarded as safe based on longstanding traditional use across multiple Asian populations without documented reports of acute toxicity. Given that oxyresveratrol shares structural similarity with resveratrol, theoretical interactions with CYP450 enzymes (particularly CYP1A2 and CYP3A4) and anticoagulant medications cannot be excluded, though no empirical interaction data exist for this specific compound from A. lakoocha sources. Pregnancy and lactation safety is entirely unstudied; in the absence of safety data, use of concentrated extracts (bark, heartwood, or standardized oxyresveratrol) beyond normal dietary fruit consumption is not advisable during pregnancy or breastfeeding.

Frequently Asked Questions
What is Artocarpus lakoocha used for in traditional medicine?
In Thai and South Asian traditional medicine, Artocarpus lakoocha bark and heartwood have been used primarily as topical anti-inflammatory and wound-healing agents, as well as antifungal preparations. The reddish heartwood, rich in oxyresveratrol and prenylated flavonoids, is considered the most medicinally active part of the tree in Thai ethnomedicine.
What is oxyresveratrol and why is it important in Artocarpus lakoocha?
Oxyresveratrol is a stilbenoid polyphenol concentrated in the heartwood of Artocarpus lakoocha and is considered its primary bioactive compound. It inhibits tyrosinase enzyme activity (relevant to skin lightening), suppresses arachidonic acid-derived inflammatory mediators, and activates Nrf2-dependent antioxidant gene expression including HO-1 and NQO1 in cell-based studies.
Is there clinical trial evidence supporting Artocarpus lakoocha health claims?
No human clinical trials have been published for Artocarpus lakoocha in any therapeutic indication as of the current literature. All available evidence is limited to in vitro phytochemical assays, antioxidant capacity measurements, and cell-based mechanistic studies, meaning clinical benefit claims cannot yet be substantiated with controlled human data.
What parts of the Artocarpus lakoocha tree have the highest medicinal compound concentration?
The bark contains the highest total phenol content at 10.14±0.72 g GAE per 100 g, while leaves show the highest flavonoid concentration at 17.13±1.77 g QE per 100 g. The heartwood is the primary source of oxyresveratrol and triterpenoids such as lupeol, making it the part most commonly targeted for medicinal and cosmetic extract production.
Is Artocarpus lakoocha safe to consume or apply topically?
The fresh fruit has a long history of safe dietary consumption across Southeast Asia and India without documented toxicity reports. However, no formal safety studies, maximum dose thresholds, or drug interaction data exist for concentrated bark or heartwood extracts; use of such extracts during pregnancy or breastfeeding is not recommended due to a complete absence of safety evidence.
What is the difference between Artocarpus lakoocha bark extract and leaf extract in terms of bioavailability?
Artocarpus lakoocha bark contains higher concentrations of oxyresveratrol and prenylated flavonoids compared to leaf extracts, making bark-derived supplements potentially more potent for anti-inflammatory and antioxidant effects. However, leaf extracts still activate the Nrf2 antioxidant defense pathway, though typically at lower efficacy levels. The choice between forms depends on whether maximum compound concentration or broader phytochemical diversity is prioritized.
Does Artocarpus lakoocha interact with NSAIDs or other anti-inflammatory medications?
Artocarpus lakoocha's anti-inflammatory mechanism through arachidonic acid cascade suppression suggests potential additive effects with NSAIDs like ibuprofen or naproxen, which could increase the risk of gastrointestinal side effects or bleeding. Individuals taking prescription anti-inflammatory or anticoagulant medications should consult a healthcare provider before combining them with Artocarpus lakoocha supplements. The stilbenoid compounds may also interact with drugs metabolized by cytochrome P450 enzymes, affecting medication efficacy.
Who would benefit most from Artocarpus lakoocha supplementation—athletes, older adults, or individuals with inflammatory conditions?
Individuals with chronic inflammatory conditions such as arthritis, inflammatory bowel disease, or wound healing issues may benefit most from Artocarpus lakoocha due to its documented arachidonic acid pathway inhibition and traditional use in wound care. Older adults experiencing age-related oxidative stress could also benefit from the Nrf2 activation, which supports cellular antioxidant defense. Athletes may find value for post-exercise inflammation management, though research specifically in athletic populations remains limited.
