Orangutan Seen Treating Wound with Herbs

Recent findings suggest that orangutans possess a sophisticated understanding of medicinal herbs, as demonstrated by a male Sumatran orangutan observed treating a facial wound with sap and chewed leaves from a plant with known healing properties.

This discovery adds a new dimension to our understanding of orangutan behavior and raises intriguing questions about the origins of human wound care practices. Dr. Caroline Schuppli, the senior author of the research conducted at the Max Planck Institute of Animal Behavior in Germany, emphasizes the significance of this finding in tracing the evolutionary roots of such behaviors.

The study, published in Scientific Reports, recounts the observation of a male Sumatran orangutan named Rakus treating his facial wound. After sustaining the injury, Rakus was observed feeding on the stem and leaves of Fibraurea tinctoria, a plant known for its medicinal properties. Subsequently, Rakus began chewing the leaves and applying the plant juice directly onto his wound, a behavior repeated until the wound was fully covered. Remarkably, within days, the wound had closed, and within weeks, it had healed with only a small scar remaining.

The plant utilized by Rakus contains substances with antibacterial, anti-inflammatory, and pain-relieving properties, among others. This suggests a deliberate selection of medicinal resources by the orangutan, indicative of a sophisticated understanding of the healing properties of plants. While it remains unclear whether Rakus independently discovered this medicinal application or learned it from another orangutan, the observed behavior underscores the cognitive capacities of these primates.

This groundbreaking observation offers valuable insights into the complex cognitive abilities of orangutans and their potential implications for the evolution of human medicine. It highlights the adaptive significance of self-medication in wild animals and underscores the importance of further research into the medicinal practices of non-human primates.
