castoreum

From the strength of the castoreum, the Siberians infer that other parts of the animal must possess peculiar virtues.

Castoreum has done good in this as in spasmodic dysmenorrhea.

Another time a beaver, passing over a trap to get the castoreum, had his hind-leg broken.

At length an Indian tried whether a male might not be caught by adding some of the castoreum.

When genuine and unadulterated, castoreum will preserve its flavour for ten years.
