#Plucheaindica

For centuries, the humble leaves of khlu, known botanically as Pluchea indica (L.) Less., have quietly woven themselves into the tapestry of Thai traditional medicine. Heralded in folklore from Isan to the Southern provinces, this plant—also called หนาดงั่ว, หนวดงิ้ว, เพี้ยฟาน, ขลู, คลู, and ขี้ป้าน, depending on local dialect—has been held as a village remedy for everything from inflamed joints to kidney health. Today, Pluchea indica stands at a fascinating crossroads, with a growing body of research seeking to validate and explain the benefits extolled by generations of healers. How does ancient wisdom surrounding khlu measure up to the scrutiny of modern science, and what should health-conscious Thais know about harnessing its potential responsibly?

Khlú, known scientifically as Pluchea indica, has long been a staple in Thai traditional medicine. Across Isan to the southern provinces, it appears in folk remedies for joint inflammation and urinary concerns, with local names such as หนาดงั่ว, หนวดงิ้ว, เพี้ยฟาน, ขลู, คลู, and ขี้ป้าน. Today, researchers are exploring whether this hardy plant’s age-old wisdom holds up under scientific scrutiny, and what it means for health-conscious Thais.

Khlú thrives in Thailand’s marshes, tidal flats, and roadside ditches. It is more than a weed in Thai households: stems ground for kidney stones, bark used for hemorrhoids, and especially the leaves brewed as a tea to ease inflammation, urinary discomfort, or minor infections. The plant’s enduring presence in rural and peri-urban life highlights a cultural belief in healing drawn from the immediate environment.
