In true epilepsy it has, like most other nerve-tonics, been used and commended, but evidence of its really preventing the attacks is contradictory. Broadbent found it useful in epileptiform vertigo (Practitioner, viii.-x.), and Anstie observed it relieve the depression of epileptics and improve their temper and power of control (Medical Times, i., 1862). In the early period of the disease, when dependent upon sexual abuse, I have known phosphorus prove very beneficial. I remember especially the cases of two men, aged nineteen and twenty-three, whose attacks began soon after puberty, and who had taken large doses of potassium bromide without evident relief, and who became quite freed from their attacks during a course of phosphorus, and have continued free from them during the four and six years that have since elapsed. The dose was only 1/100 gr. three times daily, which was continued (irregularly) for twelve or fifteen months.
