Horsetail (Shavegrass) Powder

Horsetail (shavegrass) has found many uses through the ages, most of which can be traced in some way to its very high silica content. The epidermis contains so much silica that bunches of the stem have been sold for polishing metal and used to be imported from Holland for the purpose. Its high mineral content, astringency and effect on the urinary and circulatory systems gained it high regard among the old herbalists as a wound healing herb.
