I’d start with Plasma Protocol to completely repair organs, especially when you’re not sure which organs (or what about them) need healing. Plasma Protocol will do that for you.
If you wanted to go all out, you might want to throw in BoL and the various anti-aging fields (Search will help you find those).
BTW, what did the doctor say? (A yellow tongue is sure to have provoked a comment from them, yes?)
Feel better.
