When the exact “spot” is pressed--and a little practice will soon make the finding of this almost automatic--the pressure should be firmly held for several minutes. The throat may feel slightly “lame” afterwards--but this soon passes off. If it does not, pressure brought to bear upon the appropriate thumb or finger will relieve the “lameness.” 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. [Illustration: FIG. 23--Anterior quarter of tongue coated with tincture of iodin--both surfaces.] [Illustration: 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.] If the use of the probe through the nostrils seems too much like a surgical operation, very good--though not so rapid and effective results--will follow the application of firm pressures on the front part of the tongue, and on the floor of the mouth directly under the tongue. Also moderately tight rubber bands should be worn on the thumbs and first fingers of both hands for five or ten minute intervals, several times a day. This might be supplemented also with strong pressure with the finger and thumb over the bridge of the cougher’s nose.
