The Kreuznach waters acted so favorably upon several of my patients with unilocular ovarian cysts, that I now always recommend one or two courses of them before advising an operation. Bromides given in 5 to 20-gr. doses two or three times daily, and continued for months, frequently diminish the size of the cyst, and improve the general health. The dose should be varied from time to time, according to circumstances.
