What can you say about tibicos or water kefir crystals as a preventive and curative herbal medicine?

My wife and I started using tibicos more than a year ago. We have 5 kids and they all love it.

Some benefits we have experienced:

- colds and coughing disappear in a day or two; phlegm easily dissolves;

- regulates menstruation, solution to menopausal dryness;

- cuts down (to zero, for us) consumption of softdrinks and tetrapacked juice drinks;

- effective relaxant;

- many of the elderly who have tried it report relief from arthritic pains;

- diabetics even report lower blood sugar
