Cantharides

Definition and stakes

1911 Encyclopædia Britannica (1911)

“ Cantharides owe their value to the presence of a peculiar chemical principle, to which the name cantharidin has been given. It is most abundant in large full-grown insects, while in very young specimens no cantharidin at all has been found. From about one-fourth to rather more than one-half per cent, of cantharidin has been obtained from different samples; and it has been ascertained that the elytra or wing-sheaths of the insect, which alone are used in pharmacy, contain more of the active principle than the soft parts taken together ”

“ The true blistering beetle has complete wings and wing cases; its body is long and narrow, varying in size, but in general about nine lines long and two or three lines wide. It is of a rich green and golden colour, very shining and delicately tinctured, with the antennæ black, except the first joint.
“The cantharis is one of those insects which have been most anciently and most universally known. Physicians, who were the first natural philosophers, and the first observers of nature, have made mention of the cantharides in the remotest times.

Anonymous,  Insect manufactures (1847)

“ In using cantharides they are reduced to powder, mixed with some fatty substance, and applied in the form of a plaster to the surface of the body: it begins to act immediately, and separates the outer skin from the dermis with great rapidity. ”
