In an experience with several hundred cases of whooping cough we have not yet seen a failure from the proper application of zone therapy. This, I believe, is more than can be truly said of any other form of treatment.

A very few treatments only are necessary to relieve even the most aggravated case of whooping cough—or any cough which originates in the respiratory passage in that zone.

In other words, a tubercular cough, which has its cause in a lesion on the extreme right or left of the lung would not respond to pressures in the middle zones. Likewise a cough which was reflected from a congested liver, or from some other organ not in the first and second zones, would fail to respond to pressures made as here described. Any intelligent man or woman can apply these pressures—and with almost the same success as would attend the effort of the most famous specialist.

It sometimes assists very materially if the tongue, for about a third way back, is thoroly painted above and below with tincture of iodin. The mild irritation from the iodin tends to stimulate the normal function of all those zones interested in keeping up the cough.

Fig. 24—Four minutes after complete absorption of the iodin (see Fig. [23]) has taken place. The patient is indicating the sensation of heat or reaction over several zones in the chest where it is most pronounced. Few patients experience these sensations, but all patients experience the benefit. This reaction does, as a matter of fact, extend over the entire body. It is easily demon­strated that the tongue, when firmly com­pressed by the teeth, will often produce relaxation of the entire body, for the mouth is also divided into ten zones. These illustrations indicate the possibility of the speedy absorption of toxins from inner surfaces of neglected teeth and gums.
