Candida is a pathogenic yeast that causes such things as Thrush in a newborn and a vaginal infection in females. In our society that has been antibioticed to death for every runny nose, we have created an overgrowth of yeast in the body. This yeast grows in the colon and produces toxic waste products that can affect smooth muscle (causing colitis, asthma, headaches, Eustachian tube swelling causing ear infections), the brain (causing hyperactivity, memory issues, sleepiness), skin (causing rashes), mucous membranes (causing an allergic like runny nose, sinusitis) and muscles (myalgias). There are several notable books on yeast with the most popular being the Yeast Connection and the Yeast Syndrome. We test for yeast using skin and blood tests then suggest an appropriate therapy.
