We observed a wild male Sumatran orangutan (Pongo abelii) applying chewed leaves from Akar Kuning (Fibraurea tinctoria) — a climbing plant used in traditional medicine to treat conditions such as malaria and has known antibacterial, anti-inflammatory and pain-relieving biological activities of relevance to wound healing — to a wound on his cheek. The findings, which are published in Scientific Reports, represent the first report of wound treatment by a wild animal using a plant with known medicinal properties. Videos show the male orangutan Rakus emitting a long call on the day the wound was first observed. His wound on his right flange and inside his mouth are visible.
