The Crawley is a very scarce article, and in the market commands a high price. When the practitioner can obtain it and prepare it himself, he will find it one of the most valuable of the Materia Medica. It possesses decided sedative properties, and may be employed for this purpose, but its principal use is to establish waste and secretion. Following or associated with Veratrum or Aconite, there is no remedy that will more quickly and certainly establish secretion from skin and kidneys. It is probable that other uses will be developed by experiment.
