Kombucha is not eaten, but is brewed into a strong antiviral and antibacterial tea after it has been left to ferment for a week or more in a mixture of spring or filtered water, organic sugar, and organic green or black tea. Kombucha Tea is widely used to help fight immune related disease and greatly helps to boost the immune system to fight swine flu, fight influenza and other viruses with out any ill effects.
Not all Kombucha is created equal. Look for Organic Raw or Organic Unpasteurized Kombucha Tea which is in the refrigeration section the store. I make tea at home both plain and flavored which is very inexpensive. I also buy the GTS Synergy brand Kombucha Tea which is high quality, Raw, and come in flavors as well.
Well I drink Kombucha daily for about a year now and I tend to drink about a wine glass size 3 times a day before or at meals. If you have never had this tea, It is best to start out with about 2oz day for a week then increase to 2oz a day 3 times a day for about another week or so. After that drink it as much as you like but its best to divided up you Kombucha consumption throughout the day.
It is not recommended to give children under 13 years old Kombucha Tea. Not enough study has been done to determine whether or not this tea is safe for pregnant or nursing mothers.
