Right, I was saying the beavers probably got their salicylic acid from eating the willow trees. I didn't mean that people were getting aspirin from a beaver's behind!
Oh, sorry. Otherwise I was going to say “you first!”
Actually, I shouldn’t have replied to you, but rather to the original post which made it sound like the source of analgesics was beaver butts.
Oddly, I had a beaver make a dam on my property last summer. It was the first time I’d seen one up close. I can see why their fur was so coveted, it looked like deep brown silk. So the anal gland oil is good for something anyway.
