Sapium salicifolium (glandulosum) - Yerba de la flecha
"CONSTITUENTS: -
PREPARATIONS: Powdered Root. Dose: from one-half to one grain. Fluid Extract. Dose: from one to five minims. Infusion. Two ounces of the root to one pint of water. Dose: from twenty to thirty minims.
Therapy: In bilious colic caused by presence of calculous matter, sapium salicifolium combined with mono-bromated camphor promptly dislodges the gravel, calms the nervous system and quiets the distressed stomach.
The principal advantage the drug has over other cathartics and diuretics is its superior efficacy, its pleasing taste, besides its antilithic properties; the agent is not widely known. The small and pleasant dose and kindly action will give it a place as an efficient cathartic, if the above statements are confirmed."
