I have found that the ordinary solution of menthol and eucalyptol and thymol in liquid albolene will relieve hay fever if applied to a certain spot a certain number of times a day. At this point I can see the reader's face assuming an expression of pained surprise. What is there wonderful about that? Is there not a bottle of this solution on the table of every doctor in the country and does not every modern textbook on the Nose and Throat advise inhaling vapor of such a solution to relieve hay fever? True. Note that I did not say that simply spraying this solution in the nose and throat will cure hay fever. I said that it must be applied to a certain spot a certain number of times a day. It is a case of the technique being more important than the remedy; for I have no doubt that there are other medicines than ichthyol and menthol that will relieve if put on the right spot. The reason that every doctor has not discovered for himself the full value of this commonly used solution is that he did not put it on the right spot and he did not use it often enough. =The Right Spot=, as related in the chapter on Ichthyol, is either the vault of the pharynx or the upper surface of the soft palate. =Frequency.= Once or twice a day is insignificant. It must be used every hour or oftener when the symptoms are acute. Here I borrow an idea from the dermatologist who learned long ago from Unna that when an ointment rubbed on twice a day fails to cure an eczema, it may be cured by keeping the same ointment constantly applied to the part, day and night. The naso-pharynx of the hay fever patient requires the same continual application of the cure and we come as near as possible to a continual application by applying the solution every hour or two. Such frequent applications are impracticable as office treatments, but must be carried on at home or at business by the patient or a member of the family. If an expert hand is available to spray the naso-pharynx, the tip of the atomizer should be pointed forward so that the spray is directed into the posterior nares and the posterior surface of the soft palate as well as the vault of the pharynx. An adroit patient may learn to do this, but even an adroit patient, unfamiliar with the anatomy of the throat, may spray only the front of the palate and fail to get the solution correctly applied. To avoid these mistakes and insure the oil getting on the right spot, the patient should be taught the following simple technique.
