In this context, it means "the one who gives". While the general impression is that such giving is voluntary, it's not an absolute requirement of the definition.
This is a normal usage of language and not some attempt to wiggle around meaning. If this somehow makes you uncomfortable, you should remember that, if you eat meat, or otherwise consume any sort of animal product, or if you have ever done so, then aforementioned animal was straight up killed, humanely or sometimes inhumanely, to make that product.
We domesticate animals to make our lives easier through the usage of their byproducts and this is just one of those usages. Yes, an animal died, but it wasn't killed without reason or justification.
We don't live in a Star Trek world where one can wave some sort of device and the person is magically healed. People are working to get there and maybe someday they will succeed, but until then, imperfect means are all we have.
It's either that or dead humans. Which do you prefer?
