Could be fungal - could be just a die-off symptom. I would recommend the Candida Cleanse followed by the Organ Cleansers. I don't know about the Candex product - but all of my formulas are designed to work well together.
All of the products except for the Hu-Mana-Tea, the HUMACLEANSE Colon Cleanser and the cream can be stored in the freezer for up to 2 years.
