For generations, lemongrass—locally known as ตะไคร้แกง or ตะไคร้บ้าน—has enjoyed a treasured status in kitchens and clinics across Thailand. Its unmistakable citrus fragrance infuses classic Thai curries, soups, and teas, while ancient healers and modern folk alike have praised its medicinal powers. Today, scientific studies are beginning to unlock the reasons behind the enduring reverence for this remarkable plant, illuminating the complex chemistry underpinning its traditional uses and raising fresh questions about its future role in natural health.

Nestled in the lush landscapes of Thailand, Cambodia, and Vietnam, a distinctive hardwood known locally as “จันทน์ขาว” (chandan khao, or white sandalwood) has quietly served generations as a cornerstone of traditional healing. The botanical hero of this story, Tarenna hoaensis Pit., holds a place not only in herbal lore but also on the threshold of contemporary scientific curiosity. While ancient practitioners revered its aromatic wood and heartwood extracts as cooling agents, fever reducers, and components of ceremonial offerings, today’s researchers are beginning to unlock its deeper biochemical secrets, exploring the very real possibility that chandan khao holds pharmacological promise fit for modern times.

Deep in the heart of Southeast Asia, along the forested trails of Thailand and neighboring countries, grows a humble shrub known by many names—Jetaphangki, Chettaphangki, and a host of local monikers such as “plao ngam” and “tawng ta phran.” For centuries, the roots and leaves of Cladogynos orientalis, or Jetaphangki, have been prized in traditional Thai medicine cabinets, used to soothe stomach troubles, restore harmony, and invigorate the body. Today, scientists and health seekers alike are rediscovering this botanical treasure, probing its traditional roots while putting its ancient claims to the test.

For generations, the robust trees of Knema angustifolia—known in Thai as กำลังเลือดม้า (gamlang lueat ma) or sometimes as ประดงเลือด, and in English by its scientific name—have quietly offered their bark to folk healers across Thailand’s countryside. Local herbalists, passed down wisdom through word of mouth, have prized its blood-red sap for its reputed power to invigorate blood, fortify the body in times of weakness, and ease various ailments. Today, as the world looks anew at traditional remedies, a new chapter is being written for this storied botanical, reaching from Lanna village clinics to the cutting-edge labs of modern phytochemistry and pharmacology.

Long revered in sacred temples and in homes across Asia, the herbal medicine known as โกฐชฎามังสี, or “spikenard,” continues to spark curiosity among both traditional healers and modern scientists. Known scientifically as Nardostachys grandiflora DC. and often referred to by its synonym Nardostachys jatamansi, spikenard stands at the intersection of centuries-old wisdom and contemporary pharmacological research. Buried deep within Thai traditional medicine and world pharmacopoeias, its story is one of healing, ritual, and the ever-evolving quest to understand nature’s remedies in today’s world.

When it comes to traditional Thai medicine, few remedies evoke as much curiosity and reverence as โกฐก้านพร้าว (Neopicrorhiza scrophulariiflora), a rare alpine herb whose story weaves through the misty foothills of the eastern Himalayas and the centuries-old apothecaries of Southeast Asia. Known to Thai herbalists as both โกฐก้านพร้าว and by a host of evocative regional names—including กะฎุกะ and กฏุโรหินี—this plant’s dried rhizome remains a prized ingredient in classic medicine cabinets, Buddhist rituals, and even modern-day scientific investigations (phar.ubu.ac.th; Disthai.com).

In a world seeking natural remedies for complex ailments, the story of “โกฐเขมา” (Atractylodes lancea)—known regionally as “โกฐหอม,” “ซังตุ๊ก,” and “ชางจู๋”—is capturing renewed attention. Once relegated to apothecary cabinets and temple herb gardens, this humble rhizome has emerged as a protagonist in new scientific investigations. From helping with fevers and digestive troubles in Thai and Chinese traditional recipes to featuring in modern cancer research, Atractylodes lancea stands at a unique crossroads of heritage and discovery. So how does this storied plant bridge ancient 知慧 (ฉลาด) with today’s evidence-based care, and what should Thai readers know about its renaissance?

Amid a global resurgence of interest in natural and traditional remedies, one ancient Thai herbal medicine, Goṭh Phung Pla (โกฐพุงปลา), has remained a quiet but powerful staple in the nation’s pharmacopeia. Harvested from the unusual galls that form on the leaves and young shoots of the chebulic myrobalan tree (Terminalia chebula Retz. var. chebula), this remedy occupies a storied place in Thai traditional medicine, revered as both a healing talisman and a source of potent therapeutic compounds. While its efficacy has been praised for centuries in herbal manuscripts and folk culture, today’s scientists are now rigorously exploring its vast pharmacological potential, forging new links between the healing wisdom of the past and the evidence-based medicine of the present.

Among Thailand’s lush forests, hidden beneath the embrace of tangled vines and sturdy trunks, grows a climbing shrub with a storied past and promising future: กำแพงเจ็ดชั้น, or Salacia chinensis. Known by myriad regional names such as ตะลุ่มนก, ตาไก้, ขอบกระด้ง, and หลุมนก, this plant has been treasured in traditional Thai and Southeast Asian medicine for centuries. Today, as researchers peel back the layers of its traditional use, they’re uncovering scientific evidence that validates (and in some cases, challenges) the age-old practices of herbalists and healers.

Known locally as “กระวานไทย” and scientifically as Amomum krervanh Pierre ex Gagnep, Thai cardamom has held a revered place in Southeast Asian kitchens and apothecaries for centuries. With a pungent aroma and a lineage traced to the Zingiberaceae, or ginger family, this modest spice has been at the core of both Thai culinary arts and traditional medicine. Researchers are now looking beyond its fragrance, finding that ancient Thai wisdom may be holding new answers for 21st-century health challenges. What is the truth behind the folklore, and which claims stand up to rigorous scientific inquiry?
