In 1885 a 45-year-old Belgian mine official (his work was office-work) consulted me on account of sleeplessness and pain in the back. The patient had no other complaints, only he carelessly added it sometimes took him a long time to urinate, because of want of the necessary pressure. He considered this weakness as the result of gonorrhoea, from which he had suffered years ago. The sleeplessness, for which he had tried all remedies possible, would make itself known from the time he went to bed until 3 o'clock in the morning, at which time he could get sleep, but not a refreshing one, and on arising he would feel very tired, especially in the upper part of the thighs, and then would commence the pain in the back, which extended to the loins, and lasted until he went to bed in the evening, without being prompted by external influences (warmth, cold, rest, motion). Also sleeplessness nights, pain in the back daytimes. At first I considered _Nux vom._ proper, and I prescribed the same for the patient, in the 3d decimal potency, four drops twice a day. At the same time I requested the patient to bring a sample of his urine at his next visit. After some time he came back with the sample, and declared that the prescribed remedy had not shown the least effect. The urine was dark and slimy, reddish, slightly acid, and had at the bottom of the bottle brick-dust settlings. Heat did not show albumen, but by heating it the dark urine became clearer, and contained also salts of uric acid. I examined the kidneys of the patient, found them sensitive against pressure, and the diagnosis pointed to chronic catarrh of the kidneys. Sleeplessness, pain in the back and the tired feeling in the upper parts of the thigh were additional symptoms of this malady, and I determined to use _Virga-aurea_. The patient took this for three months three times a day, after which he wrote me that he was entirely well. About a year afterwards he had a relapse, but not in the form of former symptoms, but in the form of ischias, against which disease Golden Rod proved itself beneficial. In conclusion, may be mentioned a double case of the curative power of _Virga-aurea_, which also contributes to the heredity of disease. Some time ago, the wife of a farmer, 53 years old, asked me for a prescription for a trouble which she had had for twenty-six years, since her first confinement. The patient, a stout and fresh-looking person, made the following statement: After the confinement, which was very laborious, and which was followed by prolapsus uteri, the latter still existing, her legs began to swell, and an itching rash broke out by degrees. Menstruation had always come at the proper time, but suddenly stopped six months ago.
