I’ve used both marshmallow and mallow for interchangeably on serious pre-gangrene cases. I haven’t tried the hollyhock because I always have the other two within reach. If it’s all I had, I’d sure use it. Make sure to harvest hollyhock root in the fall of the first year or spring of the second because it’s a biennial. The other two are perennial (which is the other reason I prefer them).
Don't use herbs or combine herbs with medications or use them during lactation or pregnancy without talking with your healthcare provider.
