CASE II. A lady, about forty-five years of age, mother of a large family and whom I had formerly cured of an uterine tumor, was so troubled with nasal polypi that her life was very distressful; moreover, the polypi had swelled so much that they hung out of the nostrils and compelled the patient to remain within doors. This was notably the case in wet weather. Why not have them removed chirurgically? "Oh, I have had them operated on over and over again, but it's no good; they only come again worse than ever." I have tried many things to cure these polypi, but in vain; they would get temporarily better, but the first rainy weather brought them back worse than ever; hence Dr. Cooper's recommendation of _Lemna_ is very welcome to me. I ordered, as in the last case, with the result that the polypi very greatly diminished in size, and the patient could again take her place in society. I have used _Lemna_ in many other similar cases, and with the like result. In no case is the polypus really cured, but greatly diminished in size, and the patient rendered relatively comfortable. Clearly the _Lemna_ does not either kill, cure or otherwise get rid of the polypi, but it rids them of much of their succulence and thus reduces their volume, and also diminishes the influence of wet weather to which such patients are so prone. And this is no small boon; is itself in every way superior to any operative interference. The tincture I made use of was made by Dr. Alfred Heath. The first prescription only being of Dr. Cooper's own make. Both acted alike well. _86 Wimpole street, June 4, 1894._ From these remarks of Dr. J. H. Clarke and Dr. J. Compton Burnett, as well as from my own, I think there can be no doubt, whatever, that the _Lemna_ exercises a powerful influence upon the Schneiderian mucous membrane. How far it is capable by its specific action of removing large groups of polypi remains, as yet, an open question. My own experience of the treatment of nasal polypi is that we have very few remedies that can at all be depended upon for giving even temporary relief. Even from _Calcarea carbonica_ and _Teucrium marum verum_ I have not had the effects that some practitioners testify to their possessing. _Lemna_ has so far given relief in my hands to cases of nasal polypi and to cases where the nostrils were plugged by swollen turbinates and other causes in a matter far surpassing the effect I have obtained from any other remedy. In saying this I do not at all wish it to be understood that we have in it a specific for all such cases. We must remember that the symptoms in all such obscure diseases must be our guide for the selection of our remedy, and that, therefore, the important point is to work out the specific indications for the drug as we learn them from clinical observation, in the hope that on some future occasion pathogenesis may render these still more certain.
