In a groundbreaking observation, a Sumatran orangutan named Rakus was seen using a medicinal plant to treat a facial wound. This remarkable behavior provides new insights into the self-medicating practices of animals and raises intriguing questions about the evolution of medicinal knowledge in the animal kingdom.
Rakus’ Unique Self-Medication

Rakus, a male Sumatran orangutan, was observed in Gunung Leuser National Park, Indonesia, using leaves from the plant Fibraurea tinctoria, known locally as Akar Kuning, to treat a wound on his cheek. This plant is traditionally used by humans in Southeast Asia for its pain-relieving and anti-inflammatory properties. Rakus chewed the leaves, applied the juices to his wound, and used the chewed plant as a makeshift bandage.
A Significant Discovery in Animal Behavior

This is the first recorded instance of a wild animal applying a medicinal plant directly to a wound. The behavior was documented in a study published in Scientific Reports. Researchers from the Max Planck Institute of Animal Behaviour were astonished by this discovery, as it suggests a deeper understanding of medicinal properties among orangutans than previously thought.

Akar Kuning is known for its antibacterial, anti-inflammatory, and antifungal properties. Rakus’ wound healed within a month, showing no signs of infection, demonstrating the effectiveness of the plant. This observation highlights the potential for animals to use natural remedies for healing, a behavior that could have deep evolutionary roots.
Implications for Understanding Medicinal Practices

The observation of Rakus using a medicinal plant opens up new avenues for understanding the origins of self-medication in animals and humans. It suggests that the knowledge of medicinal plants may be more widespread in the animal kingdom than previously believed. This behavior could offer clues about the early development of medicinal practices in human ancestors.
Comparing Primate Self-Medication Practices

Previous research has documented other primates, such as chimpanzees and bonobos, using plants to treat ailments. However, Rakus’ behavior is unique because it involves the direct application of a medicinal plant to an external wound. This contrasts with other documented behaviors, such as chimpanzees chewing bitter plants to soothe stomachaches or rubbing themselves with chewed plants to alleviate muscle pain.
The Role of Observational Learning

Scientists speculate that Rakus may have learned this behavior from observing other orangutans or through trial and error. The possibility that such knowledge is passed down through generations or learned from peers is an exciting area for further research. Understanding how these practices are acquired and transmitted can provide insights into the social learning processes in primates.
The Evolutionary Roots of Self-Medication

The fact that self-medication behaviors are observed in some of our closest living relatives suggests that these practices have deep evolutionary roots. This behavior could date back to a common ancestor of humans and great apes, highlighting the long history of medicinal plant use. The discovery underscores the importance of preserving natural habitats where such behaviors can be observed and studied.
Future Research and Conservation Implications

This groundbreaking observation underscores the need for further research into the self-medicating behaviors of animals. It also highlights the importance of conservation efforts to protect endangered species like the Sumatran orangutan. By preserving their habitats, we can continue to learn from these incredible creatures and gain insights into the natural history of medicine.
The discovery of Rakus’ self-medication behavior is a testament to the complex and intelligent behaviors exhibited by orangutans. It provides a fascinating glimpse into the world of animal self-care and the evolutionary roots of medicinal practices.
