I'll check with my daughter in law... she is Chinese. They have all kinds of weird (and sometimes slimy looking) stuff in their fridge. Being the good sport that I am I politely tried some fish fins... When her mother comes to visit she sometimes brings her medicinal herbs and I remember seeing a package of dehydrated lily scales. It looked like just the tips were cut off and dried. I think she said they were beneficial to eyesight. My guess is they make a tea out of them.
