I absolutely adore drinking Kombucha Tea. First, it's very energizing. If you are having one of those days where you feel horrible and tired, or have a hangover type of feeling, and can hit on some Kombucha somewhere, certainly it's one of your best choices! It is a fermented tea that has super healing and health properties; too many for me to remember here, but there is quite a bit of information online. You can get it at health food stores or make your own. It's great anytime, but if you are feeling tired, it can improve you to about as good as you are going to get. If you are tired it also will help you to look more alive and feel more vibrant that day. It's a balancer, so it won't give you more stimulation than you can handle. In fact, I often choose it at bars when it's available, instead of drinking alcohol, and can still sleep well.
