#Orchidaceae

Nestled beneath the lush canopies of Southeast Asian forests thrives Wan Ron Thong—known to botanists as Ludisia discolor and cherished in Thai herbal lore as “ว่านร่อนทอง” or “Jewel Orchid.” This unassuming ground orchid, with its velvety dark leaves etched in golden veins, is far more than an ornamental plant. Across generations, its rhizome has figured prominently in folk remedies intended to soothe a range of ailments, from mysterious abdominal discomforts to urgent wounds. Modern science, armed with phytochemical analysis and laboratory models, is gradually illuminating the truths behind this legend, sparking new questions and fueling the ongoing dance between tradition and evidence-based medicine.

Wan Ron Thong, botanists’ Ludisia discolor, is known in Thai herbal lore as “ว่านร่อนทอง” or Jewel Orchid. This unassuming ground orchid hides a powerful story: its rhizome has long been used in folk remedies for abdominal discomfort, wounds, and other ailments. Modern science is starting to clarify which compounds might underlie these traditional claims, while raising new questions about safety and efficacy.

The plant thrives in the highlands of Thailand and neighboring regions, with small white blossoms that belie its deeper value in ethnomedicine. In northern Thailand, dried rhizomes have traditionally been decocted to “chase away wind,” alleviate pain, or strengthen internal organs. In China, Ludisia discolor has been described as supporting kidney function, moistening the lungs, and “clearing heat.” Such complementary medicine concepts reflect distinct cultural frameworks but share an emphasis on balance and overall system health. Thai researchers at the College of Pharmacy, Ubon Ratchathani University, highlight the plant’s role in rural healing traditions, while analyses in global literature point to similar uses across East Asia.
