If you indeed have candida it means you have a dirty terrain to sustain it - Antibiotic usage and wrong diet may have have allowed candida to take the upper hand in your gut but it only survives because your dirty terrain allows it. That means an underperforming digestive system due to mucous build up and nutrient deficiency (which prevents immune system from properly react to infection). It would make no sense to attempt destroy candida when you have a dirty digestive system, because it will come back (parasites, candida, bad bacteria).
A thourogh Bowel Cleanse can do wonders as it gets rid of the gunk that is sustaining the pathogens and blocking nutrient absorption (2 for 1 deal). By eating the right foods for your body you then kickstart the immune system and it will be able to act accordingly. Certainly Liver Flushes and short term digestive aids may be necessary to correct digestion like enzymes, probiotics, HCl.
