Blood root is an old domestic remedy. A great many eastern farmers' wives will not go into the winter without blood root in the house. In the cold winter days, when the coryzas come on, a "cold" in the head, throat and chest, then they get the blood root ready and make a tea of it. With them it is a routine remedy for "colds." They give it to combat all complaints, and there is no doubt but that even in this crude form it does break up "colds," because the provings show its relation to chest troubles and "colds" that go to the chest.
