In rural Thailand, a stately tree known as Ngiew (Bombax anceps) has long underpinned local healing practices. Also called นุ่นป่า, งิ้วป่า, งิ้วขาว, and ไกร, it has carried generations of medicinal knowledge within communities. Today, scientific inquiry is rediscovering Ngiew’s potential, highlighting a meaningful link between Thai heritage and contemporary pharmacology.
Traditional healers have long valued Bombax anceps for its diverse healing properties. Parts of the tree—the wood, bark, roots, and flowers—have been used to treat fevers, wounds, digestive issues, and more. As Thailand modernizes, this botanical knowledge faces risks. New studies aim to preserve and validate Ngiew’s healing legacy, offering a pathway that respects tradition while embracing science.
For Thai readers and neighbors in Asia, Ngiew is more than folklore. It reflects the resilience of local wisdom and the growing embrace of nature-based medicine within evidence-based healthcare.
The Ngiew story is rooted in Southeast Asia’s Theravada Buddhist cultural landscape, where trees often frame temple grounds and appear in proverbs and festival lore. In Isan, Bombax anceps grows in mixed deciduous and dry dipterocarp forests, and its fiber has historically served practical roles—from pillows to life jackets—while its symbolic significance remains strong in rural life.
In healing traditions, Ngiew’s wood and bark have been decocted for fevers, and its roots ground for digestive ailments. The tree’s various parts are often included in multi-herb tonics that support vitality and recovery after childbirth. These practices remain central to community health, particularly among the Phu Tai people of northeastern Thailand, who rely on a rich ethnobotanical heritage.
A landmark ethnobotanical study in Roi Et province documented 162 medicinal plant species used by four veteran healers. Bombax anceps ranked highly for its therapeutic value. Decoction emerged as the most common preparation method, aligning with preservation of bioactive compounds.
Among these traditional uses, Ngiew’s roots and bark target tonic symptoms, fevers, and digestive issues. Remedies for jaundice, in particular, highlighted the bark’s prominence. The consensus among healers around these uses suggests deep-rooted knowledge and long-standing observations of efficacy.
As modern medicine advances, researchers are exploring whether Ngiew’s claimed benefits hold under scientific scrutiny. Phytochemical analyses reveal bioactive compounds such as flavonoids, sterols, and phenolics in the roots and bark. These substances are associated with anti-inflammatory, antimicrobial, and antioxidant activities, supporting the plant’s traditional roles in wound healing and overall vitality.
In 2016, a Thai study screened Bombax anceps among medicinal plants for anticancer properties using ethanol twig extracts. The extracts showed moderate cytotoxicity against liver cancer cells, with a selectivity index indicating a preference for cancer cells over normal cells. The research also suggested the extracts could induce apoptosis, a controlled cell-killing process, though strength varied compared with other plants. Possible active ingredients include fatty acids that may interact with the body’s regulatory systems.
Beyond cancer, related compounds in Bombax species have demonstrated antioxidant effects that support skin healing and immune modulation. While most studies focus on Bombax ceiba, findings align with Ngiew’s traditional uses, reinforcing the value of Thai ethnobotany.
Why this matters for Thai communities today: traditional healers remain frontline health resources for many rural families. Data shows thousands of traditional practitioners across northeastern Thailand, underscoring the enduring role of local plant knowledge in everyday healthcare. However, deforestation and agricultural changes threaten the forests that sustain Ngiew and similar medicinal plants. Preserving intergenerational knowledge is equally urgent, as younger generations seek different career paths.
Historically, Bombax anceps also provided durable fibers used in pillows, ceremonial decorations, and protective gear, reinforcing its cultural prominence. The tree’s striking trunk and delicate flowers have become symbols of rural life and regional art, linking ecological health with cultural identity.
Thailand’s policymakers and educators can help by fostering sustainable harvesting, documenting traditional knowledge responsibly, and supporting research into Thai-centric medicinal plants. While laboratory results are encouraging, dosage, preparation, and individual health conditions influence outcomes. Caution is advised, particularly for children, pregnant women, and those with chronic illnesses, and medical advice should guide any use of traditional remedies.
Looking ahead, advancing Ngiew’s role in health and culture involves clinical studies to determine safe dosages and mechanisms. Phytochemical discoveries may yield new therapeutic agents or inspire gentle integrative approaches for inflammation, wound healing, and metabolic wellness. Community-led conservation and ethnobotanical documentation—done with respect for local wisdom and scientific rigor—will ensure Ngiew’s legacy endures.
Practical recommendations for Thai readers:
- Consult qualified health professionals before using traditional remedies that contain Bombax anceps, especially if you have medical conditions or take other medicines.
- Support forest conservation to protect medicinal plants and biodiversity.
- Encourage careful transmission and documentation of traditional knowledge to safeguard cultural heritage.
- Stay informed about new research from credible health authorities and academic institutions.

In sum, Ngiew stands as a bridge between ancient herbal wisdom and contemporary scientific understanding. Its journey from forest to clinic underscores the potential of Thailand’s medicinal heritage to contribute to future health solutions. Ongoing collaboration among healers, scientists, conservationists, and communities will be essential to realizing Ngiew’s full promise.
