Physiological Action—In its influence it is a tonic and mild nerve stimulant and sedative. Gaurelle, who first called attention to it, mentioned it as a most useful tonic in protracted convalescence. He had great confidence in it in persistent diarrheas, especially those of phthisis. Others have used it successfully in chronic diarrheas.

Therapy-The fluid extract of this agent, given in doses of from ten to thirty minims, has been used specifically in the treatment of headaches, other than those due to actual disease of the stomach, as from catarrh or ulceration or cancer. In many forms of headache, and especially the form due to functional gastric derangement, known as "sick headache" it is certainly a serviceable agent.
