The simple forms of inflammation are those caused by the toxins generated by the influence of organized ferments on carbohydrate foods. When no more food is taken than can be utilized by the body--than can be fitted for assimilation by the unorganized ferments (enzymes)--the body in all its parts remains in a state of health called normal. Secretions and excretions are nearly enough balanced to insure health.

If, by mental or physical habits, nerve energy is lowered--if enervation is pronounced--secretion and excretion sink below the normal; this lowers enzymic production and increases the amount of waste products circulating in the fluids of the body. If the usual amount of food is eaten. digestion will not be perfectly carried out. A certain amount will be left over and above this amount that can be digested. This left-over material must undergo microbic fermentation.

If the organism is abused by overeating, overclothing, or living in too hot houses, or when the body is especially enervated, and is then exposed to low temperatures, or passing from hot houses, hot beds, to cold air--winter --temperature--irritation of the mucous membranes of all exposed canals results, until catarrhal inflammations become a constant state of the most exposed of these membranes.

Catarrhal inflammation of mucous membranes may be considered an index of the state of digestion and assimilation. The catarrhal sign means an oversupply of food--in some cases an oversupply of food and improper food. as well as improper combinations.

This catarrhal state is general and is the culture-medium for the development of all sorts of affections which we call disease.

For children to develop the affection known as diphtheria, all they need, in addition to their general catarrhal state, is a sudden change in clothes, weather, environment, and other influences, which brings on enervation; then add to these influences an unusual meal, or an unusual amount of meat, sugar, and rich cooking, such as served on holidays.

A child may be very enervated from whatever the cause, but it will not develop diphtheria unless it is poisoned by an oversupply of animal proteid.
