on every part of the system, stimulating the glands to 

 a healthy action. Its most beneficial action is obtained 

 by the use of small doses frequently given, as large ones 

 cause violent evacuations and debility. In all chronic 

 venereal, scrofulous, and dyspeptic complaints it is 

 highly valuable ; also in dropsy, biliousness, and liver 

 disorders. 



Preparations of the root are to be preferred to those 

 of the resin. This is one of the many illustrations of 

 the fact that isolated principles do not act so well as in 

 their natural position where they are associated with

Preparations Powdered root : Dose, 5-30 grains. 

 Solid extract : Dose, 1-5 grains. Fluid extract : Dose, 

 5-30 drops. Tincture, root: Dose, 15-30 drops. Tincture, 

 resin B.P. : Dose, 5-15 drops. Podophyllin, resin:

Distinctive character The rhizome is of a reddish

 whitish, showing 20-40 yellow wood bundles enclosing 

 a central pith. This drug must be carefully distinguished 

 from English Mandrake (see Bryonia dioica).
