"But it makes a lot of sense especially when you think about how traditional healers and shamans have worked, they haven't felt that separation from nature like Western medics do. And so to rely on the knowledge of other species actually makes a lot of sense. It's probably a lot more than we know at the moment." - Jaap de Roode

Jaap de Roode is a biology professor at Emory University, and he is the author of an astonishing new book called Doctors by Nature How Ants, Apes, and Other Animals Heal Themselves. I say astonishing because I had no idea about so much of what he explores in his book. It never occurred to me to consider that other species use medicine and have been healing themselves forever.

Jaap tells stories of animals across nature, from bumblebees to chimpanzees, how they use plants and natural substances to treat infections, to ward off parasites, to self-medicate. There's so much that we have learned from them, and there's so much more that we still can.
