Latrodectus Katipo | Materia Medica by John Henry Clarke

Latrodectus Katipo. N. O. Arachnida. Tincture of living spider.

Clinical : Chorea. Faintness. Heart, slow. Nettle-rash. Å’dema.

Characteristics : Katipo is a venomous spider found in New Zealand and some parts of California. The symptoms recorded are the effects of bites. The seat of a bite becomes immediately painful and swelling occurs. In some cases the swelling does not come on until some days after the bite. In one case, five days after the bite, a scarlet papulous rash appeared on both extremities, burning like fire. Lassitude, faintness, twitchings, and in one case trismus were noted. The symptoms were somewhat slow in evolution, and in a fatal case, that of a girl bitten on the abdomen, death did not occur until six weeks after the bite.

Relations : Compare: Lat. mact., Tarent., Mygale., Aranea, Apis, Vespa, and serpent poisons.
