Action and Therapy. Fucus, once exploited as a remedy for obesity, is no longer relied upon for that purpose. It has, however, alterative properties, probably due to the haloid elements it contains, and deserves study for its influence upon waste and nutrition. It is somewhat diuretic, and is believed to give tone to lax muscular fibers. Fatty degeneration of the heart has been benefited by it, and it relieves irritation and chronic inflammation of the bladder. Its power of lessening irritation and congestion has led to its successful use in acute desquamative nephritis. From 5 to 20 drops should be taken every 3 or 4 hours.
Therapy. This agent is, used for the specific purpose of reducing unhealthy fat in excessive adiposity. If given in doses of from one-half to two drams, three or four times daily, it has reduced excessively fat patients in a satisfactory manner without interfering in any way with the normal health functions.
Action and Uses. Laminaria was brought forward as a substitute for sponge tents for the dilatation of such parts as the uterine os, urethra, etc. Being of smaller size, and of greater rigidity, they are more easily introduced into small apertures and tortuous canals than sponge tents, while, on the other hand, their very rigidity renders them more liable to produce hemorrhage when organic changes occur in the uterus, or when such growths as polypi occlude the os.
