Along the banks of lush Thai rivers and deep within the traditions of herbal wisdom, the tree known as Artocarpus lakoocha—or in local parlance, มะหาด (“mahat”)—stands tall as a symbol of healing heritage. Its storied extract, called Puag Haad (ปวกหาด), is a time-honored remedy in Thai medicine, celebrated for purifying the system and fighting parasites. Today, as a bridge between tradition and science takes shape, researchers are unraveling its secrets and exploring how the revered heartwood of this tropical tree may offer real benefits for modern ailments, from intestinal infections to diabetes and skin concerns.
Puag Haad’s re-emergence is more than a nostalgia-fueled return to roots; it is fueled by both recent pharmacological exploration and a resurgence of interest in natural therapies. For centuries, healers have relied on the foam—dried and powdered—created by simmering the five-year-old heartwood of the mahad tree. Used as a deworming agent, skin poultice, and even food coloring, this powder’s “hidden ingredient” has become a scientific talking point: oxyresveratrol, a powerful polyphenol now credited with some formidable biological properties (Wikipedia).
For Thai readers exploring herbal options, understanding the intersection of tradition, chemistry, and clinical research is crucial—not only to appreciate the cultural backdrop of Puag Haad but to navigate its modern use safely and effectively.
A Legacy Rooted in Thai Folk Medicine
The story of Artocarpus lakoocha is woven tightly into the cultural fabric of Thailand and neighboring Southeast Asian nations. The tree is as versatile in its gifts as it is grand in stature: beyond its potent medicinal uses, its fruit is relished for food, its wood forms the musical “pong lang,” and its leaves and latex enrich local farming economies (Growables.org).
Traditionally, the powdered extract called Puag Haad has played several roles:
- Anthelmintic medicine: Used to expel parasitic worms (mainly tapeworm and fluke species) in traditional therapies.
- Skin remedy: When mixed into poultices, it has been applied to soothe skin ailments and wounds.
- Digestive aid: Sometimes given for purgative effects.
- Dye and coloring: The vibrant powder is also employed in food and textiles.
The Thai Pharmacopoeia records Puag Haad as a primary ingredient in several compound remedies, while village healers often recount generations-old tales of its effectiveness for deworming and child health. Some even recall its use during monsoon seasons when parasitic infections were more common (PMC Article).
Breaking Down the Science: From Oxyresveratrol to Clinical Trials
What gives Puag Haad its potency in folk medicine? The answer, modern science suggests, is a cocktail of polyphenolic compounds, with oxyresveratrol at the forefront. This phytochemical shares structural similarities with the celebrated resveratrol found in grapes, but research indicates it may exhibit even stronger biological activity.
Recent pharmacological investigations have explored several promising actions of Artocarpus lakoocha extract, including:
- Anti-parasitic properties: Early clinical research in Thailand found that an aqueous extract of the wood was effective against intestinal tapeworms. A historic clinical study treated 39 patients with taeniasis (tapeworm infection) using five grams of crude Puag Haad; a significant majority expelled the tapeworms successfully, and side effects were mostly limited to mild gastrointestinal discomfort (PubMed).
- Anti-inflammatory and antioxidant effects: Laboratory studies highlight robust antioxidant activity, potentially helping to neutralize free radicals implicated in chronic disease and cellular aging (Wikipedia).
- Blood sugar control: Research indicates Puag Haad and its key compound oxyresveratrol may inhibit enzymes responsible for starch digestion, slowing the release of glucose into the bloodstream after meals. This effect could help mitigate post-meal spikes in blood sugar—a promising application for those at risk of diabetes (PMC Article).
- Skin health: Oxyresveratrol’s inhibition of the enzyme tyrosinase reduces melanin production, supporting its popular use in skin-whitening products and suggesting potential in treating hyperpigmentation (Taxonomic study; Wikipedia).
- Antiviral and antimicrobial activities: Some laboratory evidence suggests potential activity against viruses and bacteria, warranting further investigation.
Perspectives from Experts and Traditional Healers
Enthusiasm for Artocarpus lakoocha runs high among Thai herbalists, many of whom emphasize a respectful blend of old and new knowledge. According to a government herbal pharmacopeia reviewer, “Mahat represents the wisdom of generations—its efficacy in worm infections is recognized by both village healers and doctors interested in traditional integrative practice. We also see interest in its purified extracts for new drug development.” (PMC7154811)
A pharmacognosy researcher at a Thai university shares, “Oxyresveratrol isolated from Puag Haad has shown promising results in enzyme inhibition studies for diabetes and pigmentation. We are now testing it for broader metabolic benefits.” (PMC7056649)
Traditional practitioners, meanwhile, encourage caution and context. “It is important,” suggests a folk healer, “to use Puag Haad as our ancestors did—in moderate doses, as part of a holistic treatment, and always checked for quality. Not all brown powders are real Puag Haad.” Their message aligns with concerns about product adulteration and the need for species authentication in the modern herbal trade.
Thailand’s Place in the Herbal Revival: Tradition Meets Regulation
Thailand sits at the center of this herbal renaissance, with Artocarpus lakoocha featured in both popular markets and regulated products. The Thai Food and Drug Administration now requires quality-testing and genetic identification when Puag Haad is used as a raw material, as cross-contamination with similar species is common (PMC7154811).
With rising interest, researchers aim to standardize the oxyresveratrol content in commercial extracts and develop safer, more reliable protocols for use. This push mirrors national efforts to integrate traditional knowledge into evidence-based medical practice, honoring local culture while protecting public safety (Growables.org).
Historical and Cultural Layers: From Ancient Texts to Everyday Life
The story of Artocarpus lakoocha goes beyond healthcare. It is woven into ritual, livelihoods, and seasonal rhythms:
- Music: The tree’s wood is carved into folk instruments.
- Rural livelihoods: Its fruits, leaves, and latex have long been bartered or sold in local markets, contributing to food security.
- Scriptural mentions: The tree is cited in ancient Indian works such as the Arthashastra—a sign of its longstanding value across borders (Wikipedia).
- Environmental stewardship: Grown along riverbanks and forest farms, the tree’s presence helps combat erosion and support biodiversity.
Culturally, the process of collecting, boiling, and preparing Puag Haad is a family affair in many rural communities—an act that links the present generation with those who came before.
Looking Ahead: Questions, Challenges, and Promise
As Puag Haad rises in popularity and research pace accelerates, several trends and concerns are emerging:
- Standardization and quality: Ensuring consistent, high-oxyresveratrol content in herbal products remains a priority for both researchers and regulators.
- Potential side effects and safety: While traditional use is generally considered safe when properly prepared and dosed, scientific reviews caution about possible gastrointestinal upset and the risks of unverified commercial products. Studies on long-term effects are limited.
- Sustainability: With greater demand comes concern about over-harvesting and genetic diversity. Conservation-minded cultivation and community-based efforts are needed to secure both plant populations and local prosperity.
