discharge. The root of A. serpentaria is said to be the substance which the Egyptian snake-jugglers chew, for 
the purpose of stupifying the snakes by the introduction of their saliva into the reptiles' mouths. A. clematitis 
(from xXvifx,ot, a young shoot of the vine, in allusion to its appearance) is a species which furnishes one of the 
roots employed m European medicine. It is stimulant, stomachic, and emmenagogue ; use has been made of 
It for various purposes, as for paleness of the countenance, fistula, sarcoma, &c. A. pistolochia is also employed 
for the same purposes. It grows upon the dry stony places of Languedoc and Provence. It is used in cases ot 
obstructed perspiration, and in disorders of the lungs. The roots should be chosen of a plump texture, and a 
yellowish color. They should be newly dried, and possess an aromatic flavor and a bitter taste. 
Aristolochia trilobata and odoratissima have strong smelling roots, which are looked upon in Jamaica as 
powertul medicines, and used as stomachics by the slaves. The first species is called Contrayerva of the north 
side, from its growing in that part of the island ; and the other Contrayerva of the south side, for a correspond- 
ing reason. The root of A. serpentaria retains a place in the Materia Medica. The dried root is imported 
into this country from North America; it has an aromatic odor, not unlike that of Valerian: and a sharp, 
warm, bitter, pungent taste, resembling in some degree that of camphor. Medicinally, it is stimulating, 
diaphoretic, and tonic.
