Historical romance

[rachelwantstoread]

So I read this book last year or the year before and I can't remember the name, author or name of hero. I do remember that the heroines name was either Claire or catherine. The book is a historical romance book and its about this girl that is into some type of botonical cures and the guy is scarred and he has eczema. They meet and she makes him a few bags of oats to help his condition, and some coconut oil as well, and she helps him put it on his neck. I think the girl is supposed to be finding a husband or something like that. He starts to fall in love with her and she likes him too. And he lewaves for America, or at le eat he's going to because he doesn't think she likes him and he doesn't want to get between her and her quest to find a husband. But she goes and stops him before he leaves. I can't remember much else but ifd anyone knows the title or author I would really appreciate it!!
