Accessory Chains
Between the last two steps above, or following the last, are often introduced one or more of the following accessory chains which modify or increase the final effect and are themselves made possible by the first four steps in the direct chain.
Pathogenic germ.
Poisonous excretions from germs.
Tissue destruction by chemical action of such toxins.
Reflex muscular tension tending to increase subluxation and thus augment nerve impingement and its effects.
Or
Dietetic error.
Abnormal chemical action.
Tissue destruction or nerve irritation by chemical poisons.
Reflex motor disturbances which further limit digestive power.
Or
Abnormal mental condition.
Waste of nerve energy with production of toxins.
General metabolic disturbance.
Increased disease wherever disease previously existed.
These are offered merely as illustrations. There are many accessory chains which aid in the production or development of disease and act as secondary causes.
