Bio-Strath is an herbal yeast plasmolysate fortifying supplement that is 100% naturally sourced. Using a unique process, a special variety of yeast, Saccharomyces cerevisiae, (the same species of yeast that nutritional, engevita and brewer’s yeast comes from!) the yeast is cultivated on the following wild herbs: angelica, balm, basil, caraway, chamomile, cinnamon, elder, fennel, horseradish, hyssop, lavender, licorice, parsley, peppermint, sage and thyme. This continues for many days, until the yeast cells absorb all herbal properties. By the process of fermentation, without the use of heat and chemicals, yeast cells burst open releasing their valuable contents. This special process, called plasmolysis, supplies the body with a readily available form of nutrients.
