trodden upon ; it is very efficacious, too, for poisons. In cases 
of head-ache, the head should be rubbed with hellebore, boiled 
and beaten up in olive oil, or oil of roses, or else with peuce- 
danum steeped in olive oil or rose oil, and vinegar. This last 
plant, made lukewarm, is very good also for hemicrania^^ and 
vertigo. It being of a heating nature, the body is rubbed with 
the root as a sudorific. 
CHAP. 90. — PSTLLION, CYNOIDES, CKTSTALLION, SICELICOX, OR 
CYNOMYIA ; SIXTEEN KEMEDIES. THEYSELINTJM : ONE KEMEDY, 
Psyllion,^ cynoi'des, crystallion, sicelicon, or cynomyia, has 
a slender root, of which no use is made, and numerous thin 
branches, with seeds resembling those of the bean, at the ex- 
tremities.^"^ The leaves of it are not unlike a dog's head in 
shape and the seed, which is enclosed in berries, bears a 
resemblance to a flea — whence its name psyllion.'* This plant 
is generally found growing in vineyards, is of a cooling nature, 
and is extremely efficacious as a dispellent. The seed of it is 
the part made use of; for head-ache, it is applied to the fore- 
head and temples with rose oil and vinegar, or else with 
oxycrate ; it is used as a liniment for other purposes also. 
Mixed in the proportion of one acetabulum to one sextarius of 
water, it is left to coagulate and thicken ; after which it is 
beaten up, and the thick solution is used as a liniment for all 
kinds of pains, abscesses, and inflammations. 
Aristolochia is used as a remedy for wounds in the head ; it 
has the property, too, of extracting fractured bones, not only 
from other parts of the body, but the cranium in particular. 
The same, too, with plistolochia. 
Thryselinum^^ is a plant not unlike parsley ; the root of it, 
eaten, carries off pituitous humours from the head. 
^ Or "meagrim." 
^ Identified with the Plantago Psyllium of Linnaeus, our Fleawort, 
rieaseed, or Fleabane. 
^' Nothing, Fee says, can be more absurd than this description of the 
plant. 
2^ Whence its name " cynoides " and " cynomyia." 
29 This plant has not been identified ; Wild water-parsley, perhaps a kind 
of Sium, has been suggested.
