Bitter Ginger in Thailand: From Ancient Healer to Modern Science
Bitter ginger, known in Thai as kra-thue, is a storied plant that travels from traditional remedies to contemporary research. Classified as Zingiber zerumbet, this rhizome blends folkloric use with evolving scientific interest, inviting Thais to explore a herbal treasure with long cultural roots.
For generations, kra-thue has been a staple in Thai well-being. Among rural communities from central plains to northern highlands, it carried many names and uses. The knobby rhizome served as a remedy for digestive discomfort and muscle pains and even played a role in protective rituals. A 2011 ethnobotany study found Zingiber zerumbet widely used in ointments for sore muscles, as a carminative for indigestion, and as an appetite booster, reflecting its cross-regional value.
