An orangutan in Indonesia has been seen treating a wound with a medicinal plant, the first time this behavior has been observed in a wild animal, German researchers have found.
Biologists from the Max Planck Institute for Animal Behavior and the Universitas Nasional in Indonesia observed a male orangutan named Rakus who had suffered a facial injury.
"The raccoon was observed eating and then repeatedly applying the juice of a vine plant with anti-inflammatory and soothing properties, commonly used in traditional medicine, to his wound. He also covered the entire wound with green plant netting," the amazed biologists pointed out.
Isabelle Laumer of the Max Planck Institute for Animal Behavior said, "The raccoon likely suffered the facial injury during a fight with a nearby male."
"Raku's behavior appeared to be deliberate as he selectively treated the facial wound and no other part of the body with the plant's juice," Laumer pointed out.
"The behavior was repeated several times, not only with the juice of the plant but also later with the stronger plant material, until the wound was completely covered", the biologists pointed out.
The plant, known locally as Akar Kuning, is used medicinally by Indonesians.
It has antibacterial, anti-inflammatory, antifungal, antioxidant and other healing properties.
