Well she isn't a lycan so she doesn't have any specific lycan weaknesses. Her regeneration allows her to regenerate almost instantly, so small wounds will be gone in about half a minute. Larger and deeper wounds will take longer, at least two to five minutes. If she has numerous wounds it will take a whole lot longer, as her regeneration targets all wounds at once. 
Not sure what other weaknesses I can add actually, it's an existing mythical creature, but there isn't much info on it >.<
