1700s Rare Welsh Science Medical Book TE2-BB

I don't know the exact date of this book but the type of paper and printing look to me like late 1700s, maybe early 1800s. Not sure the exact title or nature of this book - translate seems to think it is "Every Man his Fisherman his bun.", but basically all the pages I have checked seem to do with health/medicine etc - it starts with what looks like a remedy for bad breath. This is an old piece - may have small blemishes, etc that come with age. They may also have small tears, etc around the edges. See pics for condition.
