HEMLOCK. 391 



The British colleges order an extract, a tincture, an ointment, 

 and a cataplasm. 



EXTRACT OF HEMLOCK*. 



Take of fresh Hemlock leaves a pound. 



Bruise them in a stone mortar, having sprinkled a little water upon 

 them, then express the juice, and without suffering the dregs to subside 

 evaporate it to a proper consistence. 



The extract is apt to vary very much in strength ; by com- 

 mencing, however, with a small dose, its power is soon ascer- 

 tained. Four or five grains for an adult, and one grain for a 

 child, three or four times a day, gradually increased as the pa- 

 tient can bear it. It may be given either in the form of pill or 

 in solution. The extract from the seeds is said to be more 

 powerfully narcotic than the preceding. 



TINCTURE OF HEMLOCK •!-. 



Take of dried leaves of Hemlock one ounce; 



Cardamom seeds bruised half an ounce ; 



Proof spirit sixteen ounces. 



Digest for seven days and filter through paper. 



Dose from six to twenty drops. 



Externally, the powder mixed with a bread-and-water poul- 

 tice, is the usual method of applying it, but the fresh herb is 

 preferable when it can be obtained.
