Kombucha Tea Side Effects

Kombucha tea is made by fermenting several species of yeasts and bacteria along with sugar in black tea. The colony of yeast and bacteria is called a kombucha mushroom, although it is not actually a mushroom. The resulting tea has been promoted as a panacea for serious conditions such as cancer, autoimmune disorders and aging, however there is no scientific evidence for these claims. There is, however, evidence for serious side effects of kombucha tea, including death.

Acidosis

There have been many reports of severe acidosis, which is a life-threatening condition caused by an abnormally high amount of acid in the body, in people who had recently consumed kombucha tea. The Centers for Disease Control, along with the American Cancer Society, reported that in 1995 two women were hospitalized with severe acidosis after drinking kombucha tea that they had made daily for two months. One of the women died, and the other's heart stopped but she recovered. In 2009 the case of a 22-year-old HIV-positive male, who presented with lactic acidosis and died within 15 hours of drinking kombucha, was documented in the study "A Case of Kombucha Tea Toxicity" in the Journal of Intensive Care Medicine.

Liver Damage

Liver damage is another side-effect associated with drinking kombucha. Although complete liver failure resulting in death is rare, it is not impossible. The 22-year-old who developed acidosis and died shortly after consuming kombucha tea also went into liver failure. More commonly, according to the American Cancer Society, liver damage occurs in kombucha drinkers as jaundice. Jaundice manifests itself as your body starts to turn yellow. Skin, eyes and nails are usually the parts of your body that begin to look most jaundiced.

Lead Poisoning

Lead poisoning is another risk of kombucha consumption, because of the way the tea is often made. According to the American Cancer Society and Dr. Brent A. Bauer of the Mayo Clinic, if the tea is brewed in a pot containing ceramic, lead crystal or paint, the acidic tea will absorb toxic lead from the pot. Lead poisoning has a wide variety of symptoms and is difficult to diagnose, so you should contact a physician immediately if you suspect you may have been exposed to lead.
