For centuries, the spicy, aromatic vine known as สะค้าน (sakaan)—derived from the species Piper interruptum, Piper ribesioides, and Piper wallichii—has occupied a unique place in Thai and Southeast Asian herbal tradition. Sometimes called ตะค้านเล็ก or ตะค้านหยวก, this plant has been handed down through generations of healers as both a culinary delight and a medicinal powerhouse. Now, as the scientific community shines a modern spotlight on herbal medicine, sakaan invites us to examine its rich cultural tapestry as well as the emerging evidence behind its traditional uses.

For generations, communities across Thailand have celebrated the deep-rooted legacy of มะดูก (Maduk), or Siphonodon celastrineus Griff., integrating it into a rich tapestry of traditional herbal medicine. Local names such as บักดูก (Isan), บักโคก (Khmer), and ยายปลวก (South) reflect its widespread recognition, while the regional moniker ดูกหิน hints at its multifaceted roles in Thai life.

Thailand’s markets come alive with the fragrance of som-o, or pomelo, especially during the cool season when its hefty, grapefruit-like fruits are stacked high. Many Thais relish its sweet-tart segments at temple fairs or New Year merit offerings. Yet, the greatness of the pomelo (Citrus grandis (L.) Osbeck)—known locally by names such as โกรัยตะลอง, มะขุน, มะโอ, ลีมาบาลี, and สังอู—extends far beyond the fruit bowl. For centuries, Thai traditional medicine has harnessed the thick, aromatic peel of som-o for remedies thought to ease coughs, swelling, skin woes, and indigestion. But how much of the old wisdom has stood up to scientific inquiry? Today, with both respect for heritage and a critical eye, we explore what research reveals about pomelo peel’s healing promise—and where prudent caution remains essential.

Tucked away in Thai markets and households is a small, brownish fruit with a gleaming sheen—Makham Dee Khwai (มะคำดีควาย), also known as Sapindus rarak or simply by regional names such as Prakam Dee Khwai, Makham Dee Krabue, Som Poi Thet, Chasae, and Mak Sak. Renowned for its soap-like bubbles and gentle cleansing power, this intriguing fruit has woven itself into Thai daily living, folk remedies, and spiritual heritage for generations. Yet, in recent years, Makham Dee Khwai is stepping out from the shadows of tradition and into the laboratory spotlight, with scientists exploring its true pharmacological potential and what it might really offer modern health seekers.

For centuries, Thais have trusted the hardy, angular vine known locally as “เพชรสังฆาต” (Phet Sangkhat) to treat a range of ailments—from broken bones and swollen joints to hemorrhoids and digestive woes. Today, Cissus quadrangularis is more than a staple of rural herbal gardens and traditional pharmacies; it is also the subject of cutting-edge scientific research that is uncovering the biochemistry behind its healing power and guiding new applications for health-conscious individuals.

Nestled in the heart of Thai forests and markets under local names such as “จอง,” “สำรอง,” and “พุงทะลาย,” the brown, almond-like dried fruit of the Scaphium scaphigerum tree has long held a revered place in Thailand’s herbal medicine chest. For generations, this indigenous botanical—found in everything from refreshing summer drinks to traditional remedies for coughs and constipation—has provided both sustenance and hope for wellness. Now, with a resurgence of scientific inquiry into Southeast Asian folk medicine, Scaphium scaphigerum is gaining new attention at the dynamic crossroads of ancient healing and modern pharmacology.

Across Thailand’s diverse natural landscapes, the climbing lily known as ดองดึง (Gloriosa superba L.) has captured the imagination of traditional healers and villagers for generations. With its striking flame-like petals and many regional nicknames—such as คมขวาน, ว่านก้ามปู, and มะขาโก้ง—ดองดึง holds a storied place in the country’s folk medicine repertoire.

Across Thailand’s dramatic mountain valleys and rainswept forests, one humble herb has thrived for centuries, earning a reputation as unyielding as its Thai name, “โด่ไม่รู้ล้ม”—the plant that “stands tall, refusing to fall.” Known scientifically as Elephantopus scaber Linn. and under many folk names such as “ขี้ไฟนกคุ่ม,” “หญ้าสามสิบสองหาบ,” and “หนาดผา,” this resilient perennial from the Asteraceae family has been woven deeply into the tapestry of local healing traditions. Now, as interest in herbal medicine merges with advances in biomedical research, Elephantopus scaber is stepping into the laboratory spotlight, inviting new respect for the wisdom passed down through generations—and prompting essential questions about its true medicinal potential.

For centuries, krachai, known scientifically as Boesenbergia rotunda and popularly referred to in English as fingerroot or Chinese ginger, has graced Thai kitchens and healing traditions alike. Its gnarled, finger-like rhizomes are instantly recognizable in local markets and essential in dishes such as “khao kluk kapi” and “tom kha pla,” but beneath its culinary fame lies a nuanced medicinal legacy.
