(This rather famous drug first came to notice as "Meyers' Blood Purifier;" the proprietor did not know the name of the drug used and sent a whole plant to Professors King and Lloyd, of Cincinnati, who identified it as _Echinacea angustifolia_, commonly known as "cone flower," "black Sampson," "nigger head," etc. If we may believe all that has been printed about it the remedy is a veritable cure-all. The following, however, is a safe guide; it is taken from the paper by Dr. J. Willis Candee in Transactions, 1898, of the Homoeopathic Medical Society of the State of New York, and credited by Dr. Candee to Dr. J. C. Fahnstock): He (Dr. Fahnstock) refers to the clinical application of _Echinacea_, from personal experience, substantially as follows: Cases of shifting pains in rheumatism, for which _Puls._ had been unsuccessfully prescribed, rapidly disappeared under _Echin._ Several cases of acne resembling that caused by _Bromide of Potassium_, cured. "A great remedy." When boils progress to the stage where they appear about to "point" then stop and do not suppurate, _Echinacea_ is the remedy. "In carbuncles with similar symptoms, a bluish-red color and intense pain, it will in a few hours make your patient grateful to you." It is of great value in very fetid ozæna. Beneficial in some cases of leucorrhoea with discharge bright yellow, as from a suppurating surface. Very serviceable in gangrene, where it may be classed with _Rhus_ and _Arsenicum_, perhaps ranking between them. Has attributed to it unusually good results in a case of tuberculous disease of hip and in an old, well-dosed case of destructive syphilis of throat. "In suppurative processes _Echin._ is to be thought of." In typhoid fever, diphtheria and appendicitis he has failed to substantiate the claims of other admirers of this remedy. These clinical hints have been given place as naturally following report of the proving and also because of their coming from a closely observant homoeopathist. It is unnecessary at this time to review in detail the alleged field of usefulness of _Echinacea_. All are familiar with the published testimonials and indications, some of which would lead one to think that little else is to be desired with which to combat degenerative processes in mankind. On the other hand are those, who, having tried the drug without satisfactory results, are willing to cast it aside as worthless. To such it may be well to make these suggestions: 1, to ascertain whether they have used a reliable preparation, and 2, to refrain from hasty judgment until guides for prescribing, more accurate than perchance the label on a bottle, shall have been found and consulted. My own limited experience would throw no particular light on the subject. It has, however, served to impress me with confidence in the remedy and its future. The gist of trustworthy clinical findings may be stated in two words, antiseptic and alterative.
