Shavegrass Powder, Equisetum hyemale also known as horsetail, the juice from the plant is good for anemia as it promotes coagulation of the blood. A tea made from shavegrass has been recommended for stomach and leg ulcers, urinary tract problems, water retention, excessive menstrual flow and leucorrhea. Externally, the tea makes a good wash for wounds, sores, skin problems, and mouth and gum inflammations. Use it in bath teas and body wraps to alleviate arthritic stiffness and swelling from broken bones. Horsetail absorbs gold dissolved in water better than most plants, as much as 4 ounces per ton of fresh stalks. Of course, the amount of gold in a cup of horsetail tea is quite small, but small amounts of gold are used to treat rheumatoid arthritis.
