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 trying to self-medicate in different methods. Gorillas, chimpanzees and bonobos, for instance, typically swallow complete leaves from Aspilia vegetation to eliminate intestinal parasites. In 2022, a neighborhood 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, dwelling in Gunung Leuser Nationwide Park in Indonesia.
“Rakus was injured, probably in a combat with a neighbouring male,” says Laumer.
Round three days after the combat, the workforce 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 a substitute smeared the chewed-up plant throughout his open wound.
“This went on for 7 minutes,” says Laumer. “He repeatedly put the plant exactly onto the wound, and no different physique components, after which continued feeding on it for half an hour.”
After 4 days, the wound had closed up. “It was actually quick,” she says.
In only a month, Rakus’s cheek was fully healed, forsaking a faint scar.

The therapeutic course of was in all probability accelerated by the plant, says Laumer, which has been discovered to have antibacterial, anti-inflammatory, anti-fungal and antioxidant properties. Additionally it is generally utilized by native folks to deal with situations resembling malaria and jaundice.
“To our data, that is the primary report of a wild animal exactly treating his wound with fairly a potent, medical plant,” says Laumer.
“That is actually fantastic to see,” says Simone Pika at Osnabrück College in Germany. “After all, it’s just one case. So, there are nonetheless so many questions: Is that this a behaviour he would do once more? Is that this a behaviour different people of his group would do?”
