The following is a satisfactory formula for a tragacanth dressing:
℞ Tragacanth, ...................................... gr. lxxv
Glycerini, ....................................... ♏ xxx
Ac. carbolici, ................................... gr. x-xx
Zinci oxidi, ..................................... ʒiss-ʒiiss. M.
This is painted over the parts and allowed to dry, and a mild dusting powder sprinkled over. It cannot be used in warm weather or in folds, as it is apt to get sticky. The following is a bassorin paste which may be variously medicated.
℞ Bassorin, ........................................ ʒx
Dextrin, ......................................... ʒvj
Glycerini, ....................................... ℥ij.
Aquæ, ................................... q.s. ad. ℥iij.
It should be prepared cold.
Another “drying dressing” which may be used in cool weather is:
℞ Zinci oxidi, ..................................... ℥j
Glycerini, ....................................... ℥ss
Mucilag. acaciæ, ................................. ℥ii-℥iv.
It may be variously medicated.
The plaster-mull is used in all types, especially the acute; the gelatin dressing, and the gutta-percha plaster, in the subacute and chronic; and the rubber plaster in chronic, sluggish patches only. Acacia, tragacanth, bassorin and plasment applications are used in cases of a subacute and chronic character.
