Berlin, Germany – Orangutans have long been known for their intelligence and practical skills, such as using tools for foraging. However, a new study reveals that these primates may have another surprising ability: treating wounds with medicinal herbs.
Researchers from the Max Planck Institute of Animal Behavior in Germany observed a male Sumatran orangutan using sap and chewed leaves from a plant with anti-inflammatory and pain-relieving properties to treat an open facial wound. This finding marks the first time a wild animal has been seen using a substance with known medicinal properties to heal wounds.
The discovery sheds light on the origins of human wound care, hinting at the cognitive capacities needed to develop such behaviors. The study, published in the journal Scientific Reports, details how the researchers observed the orangutan, named Rakus, treating his wound with the plant in a protected rainforest in Indonesia.
Rakus’s actions were deliberate and intentional, indicating a level of understanding of the plant’s healing properties. The plant used by Rakus is known to have antibacterial, anti-inflammatory, and antioxidant properties, among others. The researchers speculate that this behavior may have been learned or instinctual, as it has not been observed in other orangutans in the area.
The study highlights the intricate relationship between animals and their environment, showcasing the natural healing abilities of these intelligent primates. The researchers hope that this discovery will pave the way for further investigation into animal self-medication and healing practices in the wild.
Overall, the study offers valuable insights into the evolutionary history of wound care and the cognitive capacities of our primate relatives. It underscores the importance of studying wildlife behavior to gain a deeper understanding of our own biological adaptations and capabilities.
