For a few years, rosin-weed became popular and was widely commented on in the eclectic journals; but it soon dropped out of sight and is not to be found in any eclectic text books to-day.
Rosin-Weed among the Homœopaths. Rosin-weed comes into the homœopathic school through "the indefatigable Dr. Hale," as Richard Hughes calls him. The homœopathic school owes much to Dr. E. M. Hale, who enriched our materia medica with many American plants, most of them drawn from the eclectic school and, be it noted, Dr. Hale gives full credit to that school from which the new medicines came. Dr. Hale did masterly work in proving the new remedies and verifying the observations of the eclectic physicians and published his Characteristics of New Remedies in 1864. In 1868, Dr. Garrison published his paper on the use of rosin-weed in asthma and Dr. Hale, in his third edition of 1873, included rosin-weed under the name silphium laciniatum, as follows:
