There is no obvious incompatibility between loquat leaf and Fritillaria cirrhosa. Both of them have good effects of moistening lung, resolving phlegm and relieving cough, so they are often used together. It's definitely no problem to cook together, but mulberry bark is generally not made of Chinese herbal medicine, so it's hard to say whether it can be used with Eriobotrya leaf and Fritillaria cirrhosa, and it's no problem if it's mulberry leaf or mulberry bark.
