^ CXV. Artemisia santonica.{22) Santoni- 

 eum. The seeds of this vegetahle, which is well 

 known to apothecaries by tlie name of wormsecd, of 

 semen-coutra, and of zedoary, f Kaempheria rotuw 

 dtifLinn.J are very eflScacious in expelling worms, 

 particularly the lumbricoides. They have a bit- 

 ter and subacrid taste and smell ; all their activity 

 depends on a volatile oil that is easily extracted. 



They are ordered in substance, in infusion, in 

 decoction, and in form of electuary, combined with 

 other remedies., S3) The confections and pastils 

 made of them 34) answer best for those who are 

 nauseated by the odour of medicines. The dose for 

 children is two grains, and for adults a drachm, in 

 powder or electuary. The infusion is made with 

 milk, and for this, two or three drachms of the pul- 

 verized spAYien-contra is requisite. 



§ CXVI. Chenopodium antheltninticum.{25) 

 Jerusalem oak. The seeds of this vegetable, vrhich 

 grows in Pennsylvania, have an agreeable, pretty 

 strong odour, and an aromatic taste ; it is said to 

 be much used in America against worms, especially 

 against the lumbricoides. Chalmers^ who gives the 

 des'cription of it,(^6; affirms that with tlie powder 

 of these seeds only is composed that anthelmintic 

 electuary, so famous in North America. 



which, applied to the skin, excites an almost insupportable pain 

 and irritation. He thinks it may be used as a vesicatory, and 

 perhaps with the advantage of not affecting the bladder like 

 cantharides. F. Trs.
