Medicine: Chlorin

Newspapers of some months ago contained numerous accounts of the beneficial effects to be derived in the treatment of colds and diseases of the lungs in general by inhaling chlorin. Now The Journal of the American Medical Association offers an authentic opinion as to the present status of this method of treatment. “Chlorin inhalations,” it says, “will not produce bacterial sterilization of the mucous membranes, although they seem to reduce to a considerable extent the number of bacteria found on the tissues. The length of an adequate treatment, the optimal concentration of gas to be used and the method by which the gas is to be produced have not yet been thoroughly worked out. The method must, therefore, be considered as still in the experimental stage.”
