This seems to be an exciting finding. Other animals, their lives, and discoveries must also have contributed to our understanding of nature.
“Even though there is evidence of certain self-medication behaviors in animals, so far it has never been known that animals treat their wounds with healing plants. Now, biologists from the Max Planck Institute of Animal Behavior, Germany and Universitas Nasional, Indonesia have observed this in a male Sumatran orangutan who sustained a facial wound. He ate and repeatedly applied sap from a climbing plant with anti-inflammatory and pain-relieving properties commonly used in traditional medicine. He also covered the entire wound with the green plant mesh. Thus, medical wound treatment may have arisen in a common ancestor shared by humans and orangutans.”
