For candidiasis localised on the lips only has been recognised and termed by medical professions apparently as cheilo-candidiasis...? normally cleared up by some fungicide topical treatment..
there was one guy here here who sat applying "the yeasts" worst enemy SALT in poultice form to his lips over a weekend and cleared it up..?
The fact that this fungicide topical cream hasn't worked for others suggests that the root cause and reasons for others lip disorders go far deeper...and maybe systematic ie arising from the result of various variables and a more complexed process....
internal overpopulation of candidiasis if present possibly a contributing factor..so this needs to be ruled out....from the beginning which even if it isn't a root cause...is something that if identified is worth finding out as i've heard it can really impact on all other areas of health..
And is advised from one other Exfoliative cheilatis site...that tests fpr candida and ph of the blood is recommended at the outset!?
