hi grizzly-bear-official! i have a question that is kinda gross, but i hope it's not super weird. anyways, i was wondering: can bears vomit? i'm just curious because i know bears can and will eat anything they can get their paws on, no matter how rancid or rotten it is, but what if it makes them sick? do they vomit to purge the toxins out, or do they seek out and eat something that they know will help, like rats?
yes, bears are capable of throwing up. a bear that ate something bad (garbage it couldn't digest, poison berries, etc) would most likely do so to prevent itself from getting sick.
however, there have also been reported instances of bears self-medicating with medicinal plants, though these instances are not widely studied.
the phenomena of animals utilizing natural medicinal resources to their advantage is known as zoopharmacognosy (zoo: animal, pharma: medicine, cognos: to know). there are a bunch of animals that do this other than bears, but it's been most widely studied in primates.
The most notable usage of medicinal plants by bears is their use of Oshá root (translated literally to bear root). Brown bears coming out of hibernation will often seek it out - both to eat it and to chew it into a paste to rub on their bodies. The Oshá root helps stimulate their digestion and appetite.
(I am not very knowledgeable about this, but as a sidenote: Oshá root has been widely used by Indigenous North American tribes for generations. If anyone who knows more about this or has better resources would like to add onto this post, please feel free to.)
