In order to have good blood, we must breathe well. Full, deep inspirations of pure air which fill the lungs with oxygen, purify the blood. They impart to it a bright color, and send it, a life-giving current, to every part of the body. A good respiration soothes the nerves; it stimulates the appetite and renders digestion more perfect; and it induces sound, refreshing sleep.—The Ministry of Healing, 272 (1905). CH 59.2
