Cantharis vesicatoria (blister beetle) is used in Chinese medicine and has been categorized as highly toxic in the Chinese pharmacopeia. In Europe, Cantharis patches have been used since ages to treat various skin-related diseases. We investigated the cytotoxicity of the Cantharis ingredient, cantharidin, in 41 tumor cell lines (Oncotest panel) and compared the results with those of 60 cell lines of the National Cancer Institute, USA.
Cantharis is a homeopathic remedy that contains a toxic substance called cantharidin from the insect Lytta vesicatoria, commonly known as the Spanish fly or blister beetle. People use cantharis topically to heal burns and blisters, and orally to treat bladder inflammation (cystitis). Although homeopathic remedies are greatly diluted and generally not associated with side effects, high concentrations of cantharis are poisonous. People should only buy cantharis from a reputable homeopathic practitioner and should not use higher-strength concentrations than those provided in the standard homeopathic remedy.
