The Jeffersonia is a stimulant to mucous membranes, increasing their circulation, and checking profuse secretion. It may be employed in any case where these influences are desirable, and will give satisfaction. It exerts a feebly stimulant influence upon the skin, sufficient, however, to make it useful in chronic skin diseases. It is also claimed to be diuretic and anti-rheumatic. The remedy requires study, and may develop valuable properties.
