I tried calendula ointment last year for like a 1 - 2 months and wouldn't recommend it. It did a great job keeping the scabs from coming back, but it did irritate my lips (it caused a tingling burning sensation) and i think all irritation should be avoided. After i stopped taking it the scabs came back with a vengeance. IF you have to use anything using coconut oil would be first choice for me it seemed to cause the least irritation, then maybe aquaphor. Just thought I'd say my experience with it before you use it for months.
