Note 1248 — Chapter IV

At the present day the best castor comes from Russia, but the greater part of that found in shops is the produce of Canada. It is denominated a stimulant and antispasmodic. Formerly it was much used in spasmodic diseases, as hysteria and epilepsy. It is now considered almost inert, and is seldom employed. After this description, it is scarcely necessary to warn the reader against the vulgar error of confusing castor with castor oil, which is extracted from the seeds of the Ricinus communis or castor oil plant, a shrub growing in the West Indies.
