Galangal, known in Thai as kha, is more than a fragrant addition to tom yum and curries. Classified as Alpinia galanga, this fiery rhizome has long sat at the crossroads of food and medicine in Thai, Chinese, Ayurvedic, and Unani traditions. Today, modern science is uncovering why galangal has endured as a trusted remedy in Southeast Asia and beyond.

In Thai culture, galangal embodies the close bond between cooking and healing. Traditions passed from master to apprentice and mother to child describe its use to warm the body, improve appetite, settle the stomach, and boost immunity. In Ayurvedic practice, galangal is considered a hot herb, believed to balance bodily energies. In rural households, it remains a practical remedy for aches, coughs, nausea, fever, and minor infections. It has historically been used in poultices for bruises, as a post-meal digestif, and even as a preventive tonic during the rainy season when respiratory and stomach ailments are common.

Few plants hold as esteemed a place in Thailand’s culture and kitchens as ข่า (kha), known in English as galangal and classified scientifically as Alpinia galanga (L.) Willd. Beyond its unmistakable aroma infusing tom yum soup and curries, galangal’s gnarled rhizome has, for centuries, played a starring role in Thai, Chinese, Ayurvedic, and Unani medical traditions. Today, science is shining new light on why this fiery root has endured in the apothecaries of Southeast Asia and around the world.

Plao Noi, known scientifically as Croton fluviatilis Esser, is a small, evergreen shrub long valued in Thai folk medicine. Its leaves have been used for generations to ease stomach troubles, soothe ulcers, and aid wound healing. In rural Thailand, Plao Noi tea and poultices have been handed down as practical first aid, especially in Isaan and central regions. This living tradition sits at the crossroads of ancient knowledge and contemporary science, reflecting Thailand’s dynamic approach to health.

Tucked away in the diverse pharmacopoeia of traditional Thai medicine lies Plao Noi (เปล้าน้อย), scientifically known as Croton fluviatilis Esser, a humble herb whose leaves have been revered for centuries for their healing properties. With roots that reach deep into the natural and cultural landscapes of Thailand, Plao Noi exemplifies the nation’s dynamic interplay between time-honored folk remedies and the growing integration of scientific research. Today’s revival of interest in herbal medicine among health-conscious Thais is shining a new light on Plao Noi, inviting renewed appreciation of its historical roles—and prompting fresh investigation into whether its ancient reputation stands up to modern scrutiny.

Centuries before pharmacy shelves brimmed with modern medicine, Thailand’s rural communities turned to the earth for healing. Among the greenery that thrived along streams and in deciduous forests, the shrub known as เจตพังคี—Jetaphangkee—offered roots lauded for their potent effects. Today, Jetaphangkee (Cladogynos orientalis) is reclaiming its spotlight, as modern science begins to shine its lens on this fascinating herbal medicine, bridging ancient wisdom with contemporary research.

Jetaphangkee’s story is woven through the daily lives and cultural history of Thailand’s regions. Known by an array of local names—ใบหลังขาว, เปล้าน้ำเงิน, ตองตาพราน, among others—Jetaphangkee is not just an herbal remedy, but a living marker of regional identity and knowledge. For generations, communities across the North and Northeast have called on Jetaphangkee, particularly its roots, to treat ailments from digestive upset to fevers and mysterious “wind” symptoms (called lom in Thai healing traditions). In Thai folk medicine, roots are typically boiled into decoctions, alone or as part of multifaceted herbal blends, demonstrating the intricate layering of Thai pharmacopeia Medthai.com, Ubon Ratchathani University Herb Database.

Today, researchers are reexamining this remedy, connecting ancient practice with modern science to understand its potential benefits.

Jetaphangkee stories thread through Thai culture. The plant carries many regional names, reflecting its role as a living symbol of local knowledge and identity. In the north and northeast, communities have used the plant’s roots to ease digestive upset, fevers, and other ailments described in local healing traditions as “wind.” Roots are commonly boiled into decoctions or blended into multi-herbal formulas, illustrating the depth of Thai herbal practice. In daily life, such remedies reflect a pragmatic approach to health in areas where access to modern care can be limited.
