CALENDULA 



MARIGOLD, calendula officinalis. Official U. S. P., 

 Eighth Rev., but in no other country. Deleted 

 from ninth revision and incorporated in the Na- 

 tional Formulary. The tincture is used externally 

 much as is arnica; but it is superior to arnica as a 

 wet dressing in cases where without such applica- 

 tions a cicatrix would form too rapidly. It may be 

 used in most any strength, diluted with water. A 

 good dressing is calendulated boric acid, and a good 

 wet dressing is saturated boric acid solution to which 

 tr. or fl. calendula is added. Open wounds and burns 

 may be so dressed. The fl. is also combined with 

 solution of boroglycerid. The stimulation of calen- 

 dula makes it available in the local treatment of 

 various chronic lesions. In my hands calendula has 

 been satisfactory as a minor olressing, but not when 

 used alone. It stains yellow, which is an objection. 



CALUMBA 



COLUMBO, jateorhiza palmata. Official in all na- 

 tions except Serbia. 



Calumba is a valuable tannin-free bitter contain- 

 ing berberine, as well as its own essential bitter, 

 columbin.

 and "Hydrastis." The therapeutics need not be 

 repeated here. Dose: fl. 10 to 30 minims.
