The most well known medicine for Candida might be Nystatin. According to the PDR, no detectable blood levels are found following oral administration of the drug at recommended doses. It is, therefore, effective at reducing localized vaginal or intestinal yeast growth, but cannot travel through the blood stream to handle the infections in other areas. Another drug, Nizoral, impairs the productions of ergosterol, a vitamin D like substance, which is vital to the integrity of the yeast cell membranes. This drug is difficult for Candidiasis patients to absorb because proper stomach acid is required to absorb it.
Most patients are deficient in stomach acid.
Yeast infections sometimes produce symptoms that make people believe they have excess acid. Recent evidence shows this drug may cause serious liver damage or even fatal reactions. In the natural health field many substances have bean promoted as being able to reduce yeast Infection. I have found that they do create a reduction in symptoms, but cannot destroy a yeast overgrowth in a systemic case. Both undecylenic and caprylic acid are poorly absorbed into the blood stream making them ineffective in systemic cases.
