A hypochloric - or as it is more frequently designated, a dechlorinated - diet is of great value in many diseased conditions, but notably so in epilepsy. In this malady it is most useful for increasing the effects of the bromides, bromine being able to replace chlorine in the fluids and tissues, and indeed rapidly hasten its excretion from the body. This is proved by the fact that in experiments on animals the administration of bromine is followed by a marked decrease of chlorine in most of the organs. Chlorine and bromine mutually displace each other in the tissues, and Laudenheimer found that after the administration of 70 grams of NaBr in seven days, 36 grams were retained, and 26 grams of sodium chloride were liberated and excreted. In the treatment of epilepsy it is not necessary to exclude all the chlorides from the diet, but it is always wise to refrain from adding chloride of sodium to bread, replacing it by bromide of sodium in the proportion of 11/2 to 2 drachms to the pound. Ordinary bread contains from 5 to 6 grams per kilogram (about half a drachm to the pound), while in dechlorinated bread not more than 10 centigrams per kilogram should be found.
