In this manner one of the most potent and logical modern factors in the healing of disease would be conveniently consigned to the back ground in company with other simple _but unremunerative_ truths, but for the timely intervention of the new and enlightened school of independent medicine of which the Biological or Hygienic Dietetic Method of Healing is the outcome. The wonderful efficacy of natural Vinegar upon the organism and its employment in the form of Vinegar Packs and compresses dates back probably to the early traditions of the healing art, but scientific analysis of its subtle operation upon the system through the vital fluid has been left for the scientific research of today to determine. To those of the public--or the profession--therefore, who are not conversant with the subject the following notes may be valuable as descriptive of the why and wherefore of the use of Vinegar. It will be admitted, I think, that one of the most prolific sources of disease, in innumerable forms, is that of congestion of blood. The greatest danger of such congestion is inflammation. Should inflammation occur in or near a vital organ and fail to be promptly reduced and its cause (coagulation) removed, the result is decomposition--and decomposition, if not arrested means death. The most valuable--I might almost say infallible--remedy known, even to the greatest accepted authorities of physiology, for the prevention of inflammation is acetic acid in diluted form, or, in a word, Vinegar, as a restorer of the fluidity of the blood. Inflammation is the result of coagulation of the blood-albumen; congestion is its sequal, inflammation and decomposition of the tissues its climax. The last is nearly always fatal. _The manifest object therefore to be achieved in all such cases is to restore the normal fluidity and circulation of the blood_ without unduly taxing any vital organ. Thus, for instance, hot packs on the feet draw the blood towards the feet, where no vital organs exist. Hot packs act as an absorbent, by suction; cold packs, on the affected place, act in inverse ratio as an expelling force. The two operating conjointly promote full circulation and extend the absorbing tendency to the whole system. Ice, on the other hand, though not infrequently prescribed, is too strong a force. It contracts the blood vessels, arrests normal circulation, and in many cases is the direct cause of death. This is attested by the teaching of physiological law which maintains that any part of the human system which is not fed by fresh oxygenous blood _must decompose_.
