<human>: I've been hearing a lot of buzz about kombucha. What is it?
<bot>: Kombucha is a fermented tea that has been around for centuries. It’s made by adding yeast and sugar to black or green tea, then allowing it to ferment for several days. The result is a fizzy drink with a slightly sour flavor. Kombucha is believed to have many health benefits, including helping to detoxify the body, improving digestion, and providing probiotics.
