An orangutan has been seen making use of the leaves of a plant generally utilized in conventional drugs to a minimize on its face, seemingly to hasten therapeutic. It’s the first case within the scientific file of a non-human animal utilizing a plant with confirmed therapeutic properties on an open wound.
There have been a number of earlier experiences of nice apes making an attempt to self-medicate in different methods. Gorillas, chimpanzees and bonobos, for instance, typically swallow entire leaves from Aspilia crops to do away with intestinal parasites. In 2022, a group of chimpanzees in Gabon was seen placing bugs onto their open wounds, doubtlessly as a type of first support.
Within the newest examine, Isabelle Laumer on the Max Planck Institute of Animal Behaviour, Germany, and her colleagues seen a contemporary gash on the cheek of a male Sumatran orangutan (Pongo abelii) referred to as Rakus, residing in Gunung Leuser Nationwide Park in Indonesia.
“Rakus was injured, most likely in a fight with a neighbouring male,” says Laumer.
Round three days after the combat, the crew noticed Rakus chewing on the stem and leaves of an evergreen climbing plant referred to as akar kuning (Fibraurea tinctoria) and swallowing them. However after 13 minutes of feeding, the ape stopped consuming and as an alternative smeared the chewed-up plant throughout his open wound.
“This went on for 7 minutes,” says Laumer. “He repeatedly put the plant precisely onto the wound, and no other body parts, and then continued feeding on it for half an hour.”
After 4 days, the wound had closed up. “It was really fast,” she says.
In only a month, Rakus’s cheek was fully healed, forsaking a faint scar.

The therapeutic course of was most likely accelerated by the plant, says Laumer, which has been discovered to have antibacterial, anti-inflammatory, anti-fungal and antioxidant properties. It is usually generally utilized by native individuals to deal with circumstances akin to malaria and jaundice.
“To our knowledge, this is the first report of a wild animal precisely treating his wound with quite a potent, medical plant,” says Laumer.
“This is really wonderful to see,” says Simone Pika at Osnabrück College in Germany. “Of course, it’s only one case. So, there are still so many questions: Is this a behaviour he would do again? Is this a behaviour other individuals of his group would do?”
