<human>: I've been hearing a lot of buzz about kombucha. What is it?
<bot>: Kombucha is a fermented tea that has become popular in recent years for its probiotic benefits. It is made by combining black or green tea with sugar, water, and a SCOBY (symbiotic culture of bacteria and yeast). The SCOBY is a living organism that helps to ferment the tea, producing various healthful compounds including organic acids, vitamins, and enzymes. These compounds help to balance out the body’s pH levels, making it easier for the body to absorb nutrients.
