In botanical language it is known as Negundium Americanum. The common name is "box elder." It is a native of Kansas. It is a distant relative of the Acer family. I had just fairly begun to test its value when I left Kansas for California, and not finding it here, except as a shade tree on the sidewalks, I cannot get any of the root bark, which is the part used. From the short experience I had with it I conclude it is the best internal remedy we have for hemorrhoids. I have used _Colinsonia_ and _Æsculus_ without ever being impressed with their prompt action. But _Negundo_ goes at it as _Colocynth_ does in its specialty, so that the victim who has been writhing with an engorged rectum "will arise up and call you blessed." So you see this is not only a single remedy, but a "fundamental" one. The bark of the root in the yearling plants is what I prefer. Recent cases of hemorrhoids can be completely cured in this way, and the old hard cases temporarily relieved. So, gentlemen of the medical profession, I hereby introduce to you my friend _Negundo_. ONOSMODIUM VIRGINIANUM. NAT. ORD., Borraginaceæ. COMMON NAME, False Cromwell. PREPARATION.--The entire plant with root is macerated in twice its weight of alcohol. (This paper was prepared by Dr. W. A. Vingling for the Kansas State Homoeopathic Society, and reprinted in _Homoeopathic Physician_ for July, 1893). To the homoeopathic physician a new remedy, well proven, is an acquisition of greater importance than honor or wealth, for his sole duty being to relieve the sufferings of humanity, he acquires a new tool with which to accomplish his work. To the degree that the new remedy has peculiar characteristics its value is enhanced, to the extent that the pathogenetic effects are different from every other drug its usefulness becomes the more apparent. Generalities constitute a poor basis upon which to prescribe. Peculiarities, the unusual symptoms, give certainly an assurance in every prescription. We have in _Onosmodium_ a remedy with some peculiarities, and occupying a sphere unique, a curative range differing from that of every other drug. The remedy holds within its grasp the power to restore peace to the disrupted family, and to prevent the truant husband seeking the sweets of "stolen waters" by restoring the wife to the enjoyable performance of her wifely functions, and thus gratifying the dissatisfied husband. This generation of one-child families, Malthusian, with the long train of misery entailed upon the licensed family, adultery consequent upon preventive measures, _malum in se_, has its remedy in _Onosmodium_ to a very large extent. We pass to consider the more important pathogenesis of the remedy in regular course. A great part of this paper is necessarily based upon the notes of the original author, Dr. W. E. Green, with some isolated symptoms from the journals and my own experience.
