In the treatment of migraine I have been in the habit of prescribing the chlorid of ammonium with belladonna. A recent writer advises a combination of ammonium chlorid and gelsemium—the proportions are about as follows: ammonium chlorid, 20 grains; tincture of gelsemium, 15 drops, with enough cinnamon water to make an ounce. This is given in dram doses every three hours. With the tincture of gelsemium I should feel as if better results could be accomplished with this prescription by giving half dram doses every half hour or hour. I believe it would be useful in neuralgic headache also.
