It is our unique plant extract obtained from well-selected plants that are processed by our patented PLEESIT technology. Due to its high purification, it is in the shape of crystallization. (Crystallization: just like diamond andgraphite, though of same material, because of the difference of structurearrangement, the final form of the products are different.) This crystallization is the best form of plant nutrition. It has four advantages: more natural, more secured, more convenient, and more efficient.
