I've read a lot about foods that may help protect hermit crabs against infections and help heal current infections. I'm very interested in this and am wondering what all foods do this. I know about chamomile (I just bought some, yay!) and I am pretty sure calendula and clover do the same thing, but was not positive. Also, on a side note: my local co-op didn't have dandelion roots but they did have comfrey root. It was only something like $0.25 for a little bit, so I got some, not positive on whether or not they're safe. So, are they? I need more sources of cellulose, they must be bored with just cork bark.
