But if you're an animal, they can't just pop down to the nearest Walgreens when they got a tummy ache. So how do they cure what ails them? Well it turns out, some animals have figured out how to self medicate using some pretty weird stuff. [Intro] Anting! Birds have trouble with parasites. I mean, who doesn't? But for birds its really important to stay clean 'cause if you got a bunch of mites gnawing on your feathers you're not gonna be able to do all your fun bird stuff like flyin around. So a lot of them, around 250 species, do this thing called Anting. They hunker down on top of an anthill, and let hundreds of ants swarm all over them! Sounds like fun, right? Well the ants secrete chemicals like Formic Acid, which is the stuff that makes ant bites sting, but it also helps keep mites away, and other pests, and it's even thought to soothe bird's skin that's been irritated by molting. Apparently it even feels so good that sometimes birds will scoop up huge beak fulls of ants and squash them, rubbing the ant mush all over themselves. Corvids, which include Magpies, Jays, and Crows, seem to be especially fond of this. And while the occasional anting can be a healthful and invigorating activity, some birds, get, into it, like, really into it. Some scientists think that bids can actually become anting addicts. Just like other kinds of self medication, some birds carry their anting to the point where it's actually hurting other aspects of their lives and they're basically just sitting in an ant pile all day. It's pitiful, really. Our second example, Passing the Milipede. Non-Human primates have a knack for finding medicine in the wild and much like an anting bird Capuchin Monkeys in South America have discovered the healing powers of poisonous millipedes. Capuchins hunt down a particular species of milipede called O. Dorsovittatus. So they can rub it all over their bodies. They do this because the millipedes are filled with Benzoquinones. An insecticide many times more toxic that any deep woods bug repellent you've ever used. Not only do Benzoquinones pretoect the monkeys during the crazy annual mosquito season they also repel botflies which can lay eggs under a monkey's skin, forming a dangerous festering cyst that will eventually, explode! and maggots will erupt from it. but the problem with this whole scenario is that the Capuchins have to make the millipede mad before it will release it's insecticidal toxins. So the monkeys bite the millipede, which tastes terrible and are obviously really poisonus, and then they rub the angry bugs all over themselves. So a bunch of Capuchins will like, sit in a circle, passing a single milipede around taking, biting it, and then rubbin it on themselves. It's kinda sweet, actually. Our third and final example, Jaguars eating vines. You know how a cat eat some grass when it's tummy's upset and then barf, and feel better? Well in the Amazonian rainforest, Jaguars do the same kinda thing but just a little bit more Intense Jaguars have been known to eat Yage. A common vine in the Amazon that's used by native people to, mostly in religious ceremonies in a drink, called Ayahuasca. So Yage, it turns out contains compounds called Beta Carboline Alkaloids. Which make people barf! And have Diarrhea like crazy! Native people actually refer to Ayahuasca as La Purga or, The Purge. But, the chemicals that cause this purging also cause intense hallucinations! By blocking your brain's ability to reabsorb Serotonin Now nobody knows exactly whether Yage has the same psychoactive effect on jaguars 'cause it turns out it's pretty difficult to study the brain chemistry of a jaguar that's trippin out on drugs But it certainly purges their system of parasites Which im sure Is totally worth it Thank you for self medicating yourself with this episode of SciShow If you want to keep getting smarter with us you can go to youtube.com/scishow and subscribe [Outro]
