redelle,

Sheep sorrel is a not homeopathic -- so you might want to ask about that on a herbal type of bulletin board. If that's the route you wish to take...

But I would still caution you not to focus on JUST the lumps because you're missing or forgetting that the lumps are only a visible manifestation of the underlying problem. If you cut them out, or suppress them with other means of 'medicating' her, then the disturbance that caused the lumps in the first place WILL find an outlet - whether it's in the form of lumps again or something worse.

Why not get her treated by a homeopath?
