There are different strains of candida-- im sure different strains do different functions. The pathogenic strains that produce harmful metabolites that cause the issues. When candida converts to its fungal form is when it becomes even more difficult because of its resielient cell wall and its ability to adapt.
Try pine nut oil/mastic gum for the H pylori. A lot of good feedback on the Siberian pine nut oil website for H Pylori. You could even give Black seed oil a try. This seems very effective for pathogens.
Have you tried coconut milk/oil or undecenoic acid for candida?
