Fungal candida will be a part of the imbalance present in the vaginal tissues, but it's usually an imbalance in the bacterial flora. Fungal candida and bacterial flora imbalances go hand-in-hand.
One of the most beneficial species of bacteria for the vaginal tissues are the lactobacillus strains. Candida works to prevent them colonizing tissues once fungal candida develops. This then allows other problematic bacterial species to set up residence.
One of the key issues with fungal candida and bacteria is the tissue pH. Fungal candida and problematic bacteria thrive in a more alkaline pH. Yeast candida and beneficial bacteria thrive in an acidic pH. Restoring acid pH is a key to solving the riddle of vaginal imbalances. This can be accomplished with boric acid suppositories.
