Iridium is a rare metal of the Platinum group found in platinum ore. It is one of the heaviest substances known. A. J. Tafel took gr. xx. of 3rd trituration. He experienced a number of symptoms, all within two hours of taking the dose. Prominent among them were: A sensation of numbness; in ears and throughout the body. A feeling as if the eyes were being affected from below upward. A feeling as of a triangle on face, the base formed by the two malar-bones, the apex in the vertex. The numbness, and a cramp-like contraction in right calf, show a resemblance to the action of Plat. Irid. needs and deserves a fuller proving. The majority of symptoms appeared on the left side. In the Revue Hom. Française of February, 1892 (translated New York Med. Times, November, 1892), M. Laboucher gave an account of this remedy and compared it with others. He does not mention how the symptoms were obtained. They will be found in the Schema marked with "(L)" after each. Those unmarked are Tafel's. Laboucher says it is "admirable in all cases of anæmia"; is better than China for the aged and persons exhausted by disease; for puny, weak-limbed children, and those who grow too fast. He mentions a peculiar alternation of symptoms or reaction. Painful weakness of lower limbs and renal region, followed by a favourable reaction─self-confidence and facilitated mental labour. It shares with Osmium, Palladium, and Platinum a place in the treatment of rheumatism and gout. Laboucher gave Irid. in the 4th attenuation, Pallad. in the 3rd, Plat. in 2nd, and Osm. in the 1st.

Compare: In uterine diseases, Aur. and Aur. mur. (Laboucher says Irid. is superior to both and to Osm. in uterine tumours). In exhaustion after disease, Chi.
