For the first time, scientists witnessed a wild animal treating its open wound using a type of medicinal plant. An orangutan named 'Rakus', approximately thirty years old, sustained a large, deep pink wound under its right eyelid during a fight with another male orangutan in a rainforest in Sumatra, Indonesia, in the summer of 2022. After being injured, this Sumatran orangutan began chewing the stem and leaves of a vine plant, which is not part of its usual diet, but humans use it to treat wounds and diseases such as dysentery, diabetes, and malaria. It then continuously applied the ointment obtained from chewing this plant as a balm on its cheek until it was completely covered. After treatment, scientists observed no signs of infection. Its wound closed within five days and was completely healed after a month. Scientists published the results of this astonishing observation in the journal 'Scientific Reports'. This type of vine and its related species are found in the tropical forests of Southeast Asia and are known for their anti-inflammatory, analgesic, and antipyretic effects. Previous analyses of the chemical compounds of this plant indicate the presence of 'furanoditerpenes' and 'protopine alkaloids', which are known for their antimicrobial, anti-inflammatory, antifungal, antioxidant, and other biological activities related to wound healing. This behavior of the orangutan, observed in a protected area of 'Leuser Mountain National Park' in Indonesia, is the first documented case of self-medication for wounds using plant species by a wild animal and opens a new window for scientists on how to care for wounds. Isabel Lamer, a researcher at the Max Planck Institute in Germany, told the Wall Street Journal that it is unclear whether the orangutan learned this treatment from its mother, observed other orangutans, or discovered it on its own. She suggested that the orangutan might have accidentally touched its wound while feeding on the plant, and since this plant has very strong pain-relieving effects, it may have felt better and repeated this behavior several times to alleviate its pain.
Scientists Observe an Orangutan 'Self-Medicating' Its Wound with Medicinal Plant for the First Time
Scientists observed an orangutan named Rakus treating its wound with a medicinal plant for the first time. This behavior suggests wild animals may have knowledge of self-medication, which could impact our understanding of animal behavior and medicinal plant use. The findings were published in 'Scientific Reports'.
👥 Key Players
📰 What Happened
Scientists observed a wild orangutan named Rakus treating its wound with a medicinal plant for the first time, suggesting that animals may possess knowledge of self-medication. This behavior was documented in a protected area of Indonesia.
- Rakus sustained a wound during a fight and used a medicinal plant to treat it.
- The plant has known medicinal properties, including anti-inflammatory and antimicrobial effects.
💡 Why It Matters
📚 Background
Self-medication in animals suggests a level of intelligence and adaptability that can inform conservation strategies. This behavior has been observed in various species but is rare in wild animals.
