Fibraurea tinctoria is a species of flowering plant in the family Menispermaceae . [2] [3] It is native to Assam, Borneo, Cambodia, India, Java, Laos, Malaysia, Myanmar, the Nicobar Islands, the Philippines, Sulawesi, Sumatra, Thailand, and Vietnam, where it grows in wet tropical areas. [1] It is considered locally common. [4] It fruits in April and May, producing yellow-orange drupes. [4] Common names for this plant include yellow root (East Kalimantan), akar palo[ what language is this? ] (Aceh), and akar kuning (Indonesian) (Central Kalimantan). [5]
The plant is used in Indonesian traditional medicine, primarily because it contains berberine, an isoquinoline alkaloid under preliminary research to identify its possible properties. [6] [ better source needed ]
During a field observation, a male Sumatran orangutan, known to researchers as Rakus, chewed vine leaves and applied the masticated plant material to an open wound on his face. [5] According to primatologists who had been observing Rakus at a nature preserve, "Five days later the facial wound was closed, while within a few weeks it had healed, leaving only a small scar."
