CHAP. 91. (12.) REMEDIES FOR DISEASES OP THE EYES. 
It is generally thought that the greater centaury strengthens 
the sight, if the eyes are fomented with it steeped in water ; 
and that by employing the juice of the smaller kind, in com- 
bination with honey, films and cloudiness may be dispersed, 
marks obliterated, and small flies removed which have got 
into the eye. It is thought also that sideritis is curative of 
albugo in beasts of burden. As to chelidonia,^^ it is marvel- 
lously good for all the affections above mentioned. Eoot of 
panaces^^ is applied, with polenta, to defluxions of the eyes ; 
and for the purpose of keeping them down, henbane- seed is 
taken, in doses of one obolus, with an equal proportion of 
opium, in wine. Juice, too, of gentian is used as a lini- 
ment, and it sometimes forms an ingredient in the more ac- 
tive eyesalves,^* as a substitute for meconium. Euphorbia,^^ 
applied in the form of a liniment, improves the eyesight, 
and for ophthalmia juice of plantago^^ is injected into the 
eyes. 
Aristolochia disperses films upon the eyes; and iberis,^* 
attached to the head with cinquefoil, is curative of defluxions 
and other diseases of the eyes. Yerbascum^^ is applied topi- 
cally to defluxions of the eyes, and vervain is used for a 
similar purpose, with rose oil and vinegar. For the treat- 
ment of cataract and dimness of sight, cyclaminos is reduced 
to a pulp and divided into lozenges. Juice, too, of peu- 
cedanum, as already mentioned,^^ mixed with meconium and oil 
of roses, is good for the sight, and disperses films upon the 
eyes. Psyllion,^^ applied to the forehead, arrests defluxions of 
the eyes.
