Wild chimpanzees actively seek out plants with medicinal properties to treat themselves for specific ailments,a new study has found. While most animals consume foods with medicinal properties as part of their routine diet, few species have been shown to engage in self-medication in a way that suggests they have basic awareness of the healing properties of the plants they’re feeding on. Until now, the challenge has been to distinguish between normal consumption of food that has medicinal value, on the one hand, and ingesting such foods for the purpose of treating a condition, on the other. “Self-medication has been studied for years, but it has been historically difficult to push the field forward, as the burden of proof is very high when attempting to prove that a resource is used as a medicine,” Elodie Freymann, a scientist at the University of Oxford in the U.K. and lead author of the study, told Mongabay in an email. To deal with the challenge, the study adopted a multidisciplinary approach, combining behavioral data, health monitoring, and pharmacological testing of a variety of plant materials chimpanzees feed on. It pooled together 13 researchers comprising primatologists, ethnopharmacologists, parasitologists, ecologists and botanists.

According to the study, pharmacological data interpreted on its own is important for establishing the presence of medicinal resources in chimpanzee diets. However, this study also relied…This article was originally published on Mongabay
