Kill bacteria
As said earlier, acetic acid is produced during the fermentation process of kombucha. Similar to polyphenols in tea, this substance can get rid of many possibly harmful microorganisms in the body. Kombucha produced from green tea or black tea seems to have powerful antibacterial properties, especially against Candida yeasts and infection-causing bacteria. While those antimicrobial effects can suppress the development of undesirable yeasts and bacteria, they don’t affect good bacteria that aid in digestion and other body functions. [3]
