These disorders are grouped under a general heading because there are a few fundamental laws that affect them all alike. Capillary congestion is a common cause in all these disorders, and anything that will produce this condition will cause, or at least augment catarrh, hay fever, asthma, influenza, and colds. As overeating is the primary cause of congestion throughout the capillary system, it, rather than exposure, is the most common cause of all these disorders. The treatment that will remove or prevent this form of congestion will, therefore, remove a primary cause, when such remedial measures may be employed as each case demands.
