#BixaOrellana

Annatto seeds, known locally as คำเงาะ, have colored Thai tea, temple robes, and folk remedies for generations. Today, researchers are exploring its health potential and safety for Thai families and travelers, linking culture to modern science.

In Thai kitchens and markets, คำเงาะ provides the vivid orange-red hue seen in curries, desserts, and especially Thai iced tea. In temples and rural homes, the seeds and leaves are part of traditional healing and cosmetic practices, with stories about wound care and fever relief passing through communities. Across Southeast Asia, color and symbolism around annatto reflect a broader belief that color offers protection and renewal.

In Thailand’s lush landscapes, the scarlet hue of kham ngeo—also known as annatto or Bixa orellana—has colored foods, fabrics, and healing practices for generations. Today, researchers and health-minded Thais are revisiting kham ngeo to explore its true potential, weaving ancestral knowledge with contemporary science.

As natural remedies gain traction, kham ngells dual roles as a dye and folk medicine gain renewed relevance. Thai consumers increasingly seek safe, plant-based options, and kham ngeo sits at the crossroads of culture and innovation. What science reveals about its traditional uses offers practical insights for daily well-being.

In the vivid palette of Southeast Asian tradition, few plants are as striking—visually, culturally, and medicinally—as คำเงาะ, a botanical treasure whose ruby-red seeds have journeyed from indigenous ceremonies to modern scientific scrutiny. Often seen as the secret behind the iconic orange hue of Thai tea and Buddhist monk robes, คำเงาะ (Bixa orellana), known globally as annatto, is much more than a natural coloring. For centuries, it has occupied a central role in folk medicine, cuisine, and ritual, and is now finding renewed interest as researchers probe its potential health benefits and safety. As Thailand’s wellness movement embraces ancient herbal wisdom, the story of คำเงาะ reveals how tradition and modern science intersect in profoundly colorful ways.
