     Animalia; Arachnida; Araneae - Spiders; Theridiidae
 It is unknown which spider K.Hering used for his remedy "Theridion". We know that they were found on Curacao and preserved in rum, probably a kind of Widow-Spider of the genus of Latrodectus. It is also unknown, whether "Theridion" is a species of its own or a variety of L. mactans, as Leeser states. lee, KH 39, Nr.5, S.197ff



Original proving

History and authority: First proved and introduced by Hearing in 1832; Hering: Guiding Symptoms, Vol. X, 296; Allen: Encyc'op. Mat. Med., Vol IX, 592.

Description of the substance

A spider about the size of a cherry stone and is found on orange trees. When young, it is velvety - black in appearance, marked with antero - posterior lines composed of white dots; the females are marked with similar strips, only larger, yellow above the anus; both sexes have square, yellow spot, notched on the edges, covering nearly whole belly. At the posterior part of the body there are three orange - red spots, the largest of them placed just below the anus, while upon the belly there is a large square, yellow spot. The thorax is black and the feet also, the latter being covered, with short, stiff hairs.

Hughes C RW Lib F:
Dr. Ozanam points out that the theridions are ordinarily innocuous, and Hering admits that his "theridion curassavicum" is very similar in many respects to the aranea tredecim-guttate, by which name Fabricius has designated the latrodectus malmignattus of Volterra and other places. It is probably, therefore, a member of the genus "latrodectus" instead of the genus "theridion" and its pathogenesis may be studied in connection with the records of the bite of the malmignatte. EDS.]
