According to recent commentary in Journal of Intensive Care Medicine about the popular Kombucha (mushroom) Tea, touted to have medicinal properties, toxicity is a real and present danger.
"Kombucha tea is black tea fermented in a yeast-bacteria medium. Several case reports exist of serious, and sometimes fatal, hepatic dysfunction and lactic acidosis within close proximity to ingestion. While Kombucha tea is considered a healthy elixir, the limited evidence currently available raises considerable concern that it may pose serious health risks. Consumption of this tea should be discouraged, as it may be associated with life-threatening lactic acidosis."
