Orangutans eat medicinal plants in patterns that suggest self-medication

Orangutans seek out plants with antimicrobial, anti-inflammatory and wound-healing properties, new research shows. Based on 20 years of observations of orangutans in Indonesian Borneo, scientists assessed how often the animals ate plants with known medicinal benefits. The findings, published in Scientific Reports, suggest orangutans eat combinations of plants in specific sequences—consistent with "self-medication" seen in other species.
