RICHARDSON-BOEDLER, reviewed (29 references) data and literature on the source of the homeopathic remedy Tarentulal hispanica and found evidence to indicate that the 'official medicinal source' is incorrect.


The European wolf spider Lycosa tarentula is said to have caused the historical phenomenon of 'tarantism' and is the official medicinal source of the homeopathic remedy Tarentula hispanica . However, scientific evidence links the spider's venomous effects with mild necrotic and minor systemic effects, which contrast with the proving symptoms of Tarentula hispanica, which display a cerebral and neural component.



A comparative investigation using toxicological and clinical findings, supported by modern and antique biological texts as well as the Homeopathic Materia Medica, traced the source of the remedy Tarentula hispanica to the Mediterranean widow spider Latrodectus tredecimguttatus, warranting a reevaluation of pharmacological preparation.
