be not ulcerated ; taken in wine, it is curative of pleurisy 

 also. 



CHAP. 55. THE CALLITHRIX: ONE REMEDY. THE PERPRESSA : 

 ONE REMEDY. THE CHRYSANTHEMUM I ONE REMEDY. THE 

 ANTHEMIS I ONE REMEDY. 



Callithrix, 58 beaten up with cummin seed, and administered 

 in white wine, is useful also for diseases of the bladder. 

 Leaves of vervain, boiled down to one third, or root of vervain, 

 in warm honied wine, expel calculi of the bladder. 



Perpressa, 59 a plant which grows in the vicinity of Arretium 

 and in Illyricum, is boiled down to one third in three heminse 

 of water, and the decoction taken in drink : the same too with 

 trefoil, 60 which is administered in wine ; and the same with 

 the chrysanthemum. 61 The anthemis 62 also is an expellent of 

 calculi. It is a plant with five small leaves running from the 

 root, two long stems, and a flower like a rose. The roots of 

 it are pounded and administered alone, in the same way as 

 raw laver. 63 



CHAP. 56. SILAUS : ONE REMEDY. 



Silaus 64 is a plant which grows in running streams with 

 a gravelly bed. It bears some resemblance to parsley, and is 

 a cubit in height. It is cooked in the same manner as the 

 acid vegetables, 85 and is of great utility for affections of the 

 bladder. In cases where that organ is affected with eruptions, 66 

 it is used in combination with root of panaces, 67 a plant 

 which is otherwise bad for the bladder. 



* 8 See B. xxii. c. 30, and B. xxv. c. 86. 



59 This plant has not been identified. Anguillara says that it is the same 

 as the " repressa," a plant given to horses by the people at Rome, when 

 suffering from dysuria. What this plant is, no one seems to know. 



60 See B. xxi. c. 30. 



ftl The same as the Helichrysos of B. xx. cc. 38 and 96. It is identified 

 with the Chrysanthemum segetum of Linnaeus, the Corn marygold. 



62 Fee identifies it with the Eranthemis of B. xxii. c. 26, which he con- 

 siders to be the Anthemis rosea of Linnaeus, the Hose camomile. 



63 See c. 32 of this Book. 



64 Hardouin thinks that it is the Apium graveolens of Linnaeus, Smallage ; 

 but at the present day it is generally identified with the Peucedanum silaus 

 of Linnaeus, the Meadow sulphur- wort, or saxifrage. 



65 Sorrel, for instance. 66 " Scabiem." 

 67 See B. xxv. c. 11.
