This plant, the aya of Dioscorides, has been celebrated 
for its healing powers from very early times, and has further 
been supposed, but on insufficient grounds, to be the Silphium 
of Cyrenaica, where it abounds. It inhabits the whole 
Mediterranean region, from the south of Spain and Morocco 
to Greece, Turkey, Rhodes, and Crete, growing in fields and 
in good soil. The root is used externally asa specific against 
pains of all kinds, and in the reduction of tumours by the 
Moors of N. Africa, where it is known under the name of 
Dreeas; but I am not aware that it has a place in the 
Pharmacopeeia of any civilized people. That it cannot be the 
famous Silphium of the ancients has been demonstrated by 
Oersted of Copenhagen, who shows that the plant represented 
on the coins of Cyrenaica as the Silphium has the remarkable 
character of growth of the true Asafcetida, and wholly differs 
from that of Zhapsia ; whence it follows, either that a plant like 
Asafetida was formerly native of Cyrenaica, but is no 
longer found there, or that the true Asafcetida was cultivated 
there, which seems to me not to be impossible. 
For the opportunity of figuring the Ziapsia I am indebted
