Re: subclinical mastitis
It sounds like you're doing everything right. I would not do cabbage leaves if I were you (never heard of raw potato), it will dry your supply right up.
I've heard taking soy lecithin supplements is supposed to help with plugged ducts, but I'm not sure if it's more a preventative measure or if it would help with one you already have. Maybe someone else can chime in on that.
