Flora Florasil - Vegetable silica is beneficial for healthy hair, nails, teeth, and for the maintenance of skin elasticity. Vegetable silica is also beneficial in the production and maintenance of strong bones, joints, muscles and organs. Modern food processing reduces the availability of silica in our diets. Extracted from the Spring Horsetail, known for its high vegetable silica content, Florasil contains high quality vegetable silica, rich in bioflavonoids and other minerals, which are essential for proper absorption and utilization of silica in our bodies.
