When I was in the hospital, they gave me a big bracelet that said ALLERGY, but like. I'm allergic to bees. Were they going to prescribe me bees in there.
So there's a medication called hyaluronidase. It's used to make other medications absorb better, because it makes the cell wall more permeable.
One common usage is to make local anesthetic more effective during surgery, for instance. It's used in a number of injected medications.
Bee stings contain an enzyme very similar to this medication, so sometimes, people with bee allergies have an allergic reaction to hyaluronidase.
This is called cross-reactivity, where your body mistakes something for the thing it's actually allergic to, and has an allergic reaction anyway. For instance, sometimes people with latex allergies also are allergic to bananas and other fruits. They don't actually contain latex, but there are some similar proteins.
Apparently, hyraluronidase used in humans is derived from one of four sources: sheep testicles, cow testicles, cow testicles again, and GMO hamster ovaries.
tl;dr: They won't inject you with bees, but they might inject you with purified cow testicle juice, and your body might say 'eh, cow balls are BASICALLY bees' and try to kill you anyway.
The world is full of such beauty and wonder. Thank you for that sentence.
