Animal Medication: How Animals Heal Themselves
Two decades ago, Jaap de Roode made a groundbreaking discovery that changed the course of his scientific career. While studying the ecology and evolution of parasites and their hosts, he stumbled upon something truly remarkable: monarch butterflies seemed to be utilizing the medicinal properties of plants to treat themselves and their offspring.
At the time, the idea that insects could self-medicate seemed far-fetched. Fast forward to today, and de Roode is now a world-renowned expert in the field of animal medication, with his own lab at Emory University in Atlanta, Georgia. In a recent interview with New Scientist, he discussed his research, his new book titled “Doctors by Nature: How ants, apes and other animals heal themselves,” and his belief that animals possess valuable medicinal knowledge that could benefit human health.
One of the key moments that ignited de Roode’s interest in animal medication was a chance observation made by Michael Huffman of Kyoto University and Mohamedi Seifu Kalunde, a national parks ranger in Tanzania. While tracking an elderly chimpanzee named Chausiku, they noticed that she was exhibiting unusual behavior – she was withdrawn, napping during the day, and suffering from diarrhea. To their surprise, Chausiku was seen consuming the bark of a plant called Vernonia, also known as bitter leaf, which was not a part of her usual diet.
Seifu, who was also a traditional healer, explained to Huffman that he used Vernonia for its medicinal properties. This observation sparked de Roode’s curiosity and set him on a path to explore the phenomenon of animal self-medication further.
Through his research, de Roode has uncovered various instances of animals using plants and other natural substances to treat ailments and maintain their health. From chimpanzees consuming bitter pith to kill worms to woolly bear caterpillars self-medicating with specific plants, the natural world is full of examples of animals exhibiting medicinal behaviors.
By studying how animals heal themselves, de Roode believes that we can gain valuable insights into potential treatments for human health conditions. The intricate knowledge that animals possess about the medicinal properties of plants could hold the key to developing new therapies and improving our understanding of health and wellness.
In conclusion, the field of animal medication offers a fascinating look into the ways in which nature has equipped animals with the tools to heal themselves. By tapping into this wealth of knowledge, researchers like Jaap de Roode are paving the way for new discoveries that could benefit both animal and human health in the future.
