_Arsen. brom._ is also a powerful remedy in diabetes mellitus and insipidus, for I cured cases with it where the patient had already been reduced from 138 pounds to 98, and where the urine could be condensed, by boiling, into syrupy consistency. Mixed diet may be allowed, though I insist upon large quantities of fresh meat during treatment with _Bromide of arsenic_. Let the patient take three drops thrice daily in a glass of water, and after a week the insatiable burning thirst will be quenched, and these doses must be continued till the quantity of sugar in the urine is reduced, when the drug might be taken twice a day and continued for a long time. A diabetic patient needs fresh pure air if he wishes to get well; confinement in a room or in the office prevents the action of any treatment, for it needs ozone to reduce the sugar of the blood into carbonic acid and water. ASPIDOSPERMINE.[B] [B] _Aspidospermine_ or _Quebrachine_ is derived from the Chilian "white Quebracho" (_Aspidospermia Quebracho_). At Santigo de Chile the bark is used as a substitute for Cinchona as a febrifuge. The alkaloid forms salts with Citric, Hydrochloric and Sulphuric acids. PREPARATION.--Trituration of the alkaloid. (Dr. Edwin M. Hale communicated the following concerning this alkaloid to the _Homoeopathic Recorder_ for 1889): _Dyspnoea._--This alkaloid is from the South American tree--_Quebracho_. The maximum dose, according to Merck, is 1/10th grain. I use the 1/500th trituration, which I find most efficient in doses of 2 to 5 grains. CASE I.--A boy of ten. The attacks of spasmodic dyspnoea were a sequel of hay fever. The aggravation was at night, when lying down, or sleep was impossible. I tried _Ipecac_ and _Arsenic_, but with no effect. _Aralia_, also. (I never had any curative or palliative effects from _Aralia_.) Prescribed _Aspidospermine_, 1/500th trituration, 2 grains every two hours, all day. The night was comfortable, could lie down and sleep. Continued the remedy for four days, when he was so much better that the medicine was suspended. CASE II.--Cardiac dyspnoea in a man of 60. Valvular disease, hypertrophy with dilatation. Distressing difficulty of breathing from the slightest exertion; had to sit upright day and night. Face livid from venous stasis. _Strophanthus_ regulated and strengthened the heart's action, but only slightly benefited the dyspnoea. Five grains of _Aspidospermine_, 1/500th trituration, every two hours effected a marvellous change. He could walk about the house and out to his carriage with but little discomfort. He has now continued it three weeks. Observes no unpleasant symptoms. Can lie on his back and right side and is very grateful for the relief. It seems to act as well as an aid to _Digitalis_, or _Strophanthus_, in cardiac dyspnoea. AURUM MURIATICUM NATRONATUM. COMMON NAME.--Chloride of Gold and Sodium.
