In the heart of the Indonesian rainforest, a fascinating spectacle of nature unfolds. Scientists have observed orangutans, one of our closest primate relatives, using medicinal plants to treat their ailments. This behavior, previously unseen, provides a captivating insight into the natural world and the inherent wisdom of these remarkable creatures.
A Healing Touch in the Wild
In a groundbreaking observation, scientists reported an orangutan named Rakus treating a wound with a tropical plant. Rakus, a wild male Sumatran orangutan residing in Gunung Leuser National Park, Indonesia, was seen plucking and chewing up leaves of a medicinal plant used throughout Southeast Asia. This plant is known for its pain-relieving, anti-inflammatory, and antibacterial properties.
Rakus then applied the plant juices to an injury on his right cheek. In a display of natural intelligence, he pressed the chewed plant to cover the open wound, akin to a makeshift bandage. Within a month, photographs showed the animal’s wound had closed without any complications.
A Glimpse into Our Ancestors’ Pharmacy
This observation offers a new perspective on natural healing methods and behaviors, and where these inclinations may have originated. "We often lose sight of the fact that modern medicine is derived from a very ancient system of knowledge that began millions of years ago in a variety of habitats about which our knowledge is only beginning to expand,” says Mary Ann Raghanti, a biological anthropologist.
The recorded event transpired during the summer of 2022, at the Suaq Balimbing research station within the Gunung Leuser National Park in Sumatra, Indonesia. This rainforest is home to the highest density of Sumatran orangutans on the planet.
More Than Just a Single Observation
While this is a single observation, it is not an isolated incident of great apes using medicinal plants. Bornean orangutans have been observed rubbing themselves with juices from a medicinal plant, possibly to reduce body pains or chase away parasites. Similarly, chimpanzees in multiple locations have been observed chewing on the shoots of bitter-tasting plants to soothe their stomachs.
These observations underscore the intelligence and adaptability of orangutans and other great apes. They also highlight the importance of preserving their natural habitats, which are under threat from deforestation and other human activities. As we continue to learn from these remarkable creatures, we are reminded of the intricate connections between all living beings and the natural world.
In the end, the healing wisdom of the orangutans serves as a testament to the profound mysteries of nature that are yet to be fully understood. It is a gentle reminder that sometimes, the best remedies are found not in a lab, but in the heart of the wild.
