As medicine
The horsetail plant is used to make a medicinal tea to treat kidney problems, bladder infections or urinary track problems. To treat a bladder infection, a tea is made with the horsetail plant and large amounts of the tea are taken to clear the condition. A cup of the tea is taken two or three times during the night. Cups of horsetail tea are also taken during the day along with spruce pitch tea for three days. Ruth said that a bladder infection could occur when the outside conditions are wet and cold and often during camping trips. She said,

…[drink]the tea from the horsetail and you'll feel comfortable within just a few hours…then [drink] it for a few days. And after three or four days…if you feel the discomfort coming back, [drink] it immediately and go for another three or four days.

Drink the horsetail tea and water throughout the day to flush out the whole system.
