Is hops hard on the liver?

I'm curious, is it true that consuming hops, a key ingredient in beer, can be hard on the liver? I've heard some people claim that the bitterness of hops may cause stress on the liver, leading to potential health issues. But I'm also aware that moderate alcohol consumption, including beer, is generally considered SAFE for most adults. So, is there any scientific evidence to support the idea that hops specifically can harm the liver, or is this just a myth?
