Cimicifuga Racemosa, Black Snake Root, Black Cohosh. It is sometimes called Macrotys.
In large doses CD. S. P. Tr., I to 2 fI; f.e.. 30 I. ; ec. tr., 10 I.) it produces general relaxation, slows the pulse, and is diaphoretic. Sometimes these doses give rise to the cerebral symptoms. (Consult Bartholow.) Large doses are seldom indicated. The ec. tr. and other green root preparations are most active, and their doses are small.
In moderate and small doses cimicifuga is a most valuable remedy. It is employed in the aching and muscular soreness noted in the premonitory stages of fevers, and is usually combined with aconite in this condition. In neuralgia and muscular troubles of the heart, such as pericarditis, it is of value, and is sometimes used in the place of digitalis. Chorea is most markedly benefited by moderate doses. Ellingwood alternates it with small doses of exalgine in chorea. Acute rheumatism and rheumatic fevers involving chiefly the muscles are quite amenable to cimicifuga. Nervous troubles, such as hysteria, menstrual melancholia, and incipient puerperal insanity, are within its range. The female reproductive system is much influenced by it, relieving irregular pains, promoting involution, relieving spasm or congestion of the muscular tissues of the womb during the menstrual epoch, and in rheumatic states of the uterine muscle fibers, bringing about a regular and painless action. Pain in the loins due to gonorrhea or spasmodic stricture is relieved by it. In short, large doses influence the central nervous system somewhat like the bromides, and it acts in harmony with gelsemium, ergot, and bromides. In smaller doses its influence is to relax muscular tissues, and it cooperates with aconite, colchicum, and the salicylates. For the muscular action give f.e., 5 to I0 I. ; ec. tr., 1/4 to 2 I.; U. S. P. Tr., I0 to 20 I. ; @, 5 to 10 I.. Green f.e. same as ec. tr. or slightly more.
