Kombucha is a fermented tea containing live organisms, and Candida is a family of yeasts that are sometimes included among the cultures in kombucha, states Food Renegade. Kombucha has ancient roots as a health beverage in Eastern Europe and Asia.
Body Ecology reports that "wild ferments" or unregulated microorganisms found in some kombucha starters may contain Candida albicans, the yeast responsible for Candidiasis, a yeast infection. Kombucha including Candida strains along with beneficial yeasts may be intolerable for individuals with Candidiasis, small intestine bacterial overgrowth and irritable bowel disease. Kombucha starters don't always contain Candida; in fact, regulated kombucha starters contain only beneficial organisms and exclude pathogenic yeasts such as Candida albicans.
Regular consumers of kombucha use it as a supplement to boost immune function, improve joint health and detoxify the body, Food Renegade reports. Claims of kombucha's health benefits are based on thousands of years of empirical evidence rather than a breadth of scientific research. Kombucha, known as "immortal health elixir" in Ancient China, was investigated by Russian and German scientists as a possible cure for cancer in the first half of the 20th century, but research was suspended with the onset of the Cold War, according to Food Renegade. Regardless of the lack of scientific proof on kombucha's worth as a health supplement, the drink contains a large amount of B vitamins, antioxidants and glucaric acid.
