Candida albicans and its many varieties are always with us, in our bodies from before we are born. This otherwise harmless fungus lives in our digestive tract and on our skin, and even, in small quantities, in our mouths. This fungus is well regulated by the host’s immune system, and so this fungus, which is the cause of many nasty infections, is usually kept under control and aids us in our lives. But when the immune system weakens or fails to respond to an outbreak of candida albicans, things can get ugly. From the notoriously well-known yeast infections that over 75% of women have to deal with from time to time, to the oral thrush of infants, many skin diseases and other conditions are caused by candida.
