Botanical Name: Cassia senna

Purgative. Its action being chiefly on the lower bowel.. It increases the peristaltic movements of the colon by its local action upon the intestinal wall.
Senna is a relaxing and stimulating cathartic, expending its power chiefly upon the alvine canal, acting with considerable promptness, procuring rather free and loose discharges. It first creates a somewhat nauseating impression on the stomach, and relaxation of the pulse; but subsequently there are griping, flatulence, moderate excitement of the pulse, and excitement with engorgement of the abdominal and pelvic vessels. It leaves no tonic impression. Its main action seems to be on the smaller intestines; it is absorbed, and will affect nursing children by being given to the mother. It is best suited for cases requiring a prompt cathartic action, and when the abdominal and pelvic viscera are sluggish.
It is a popular physic in treating worms, in recent colds, etc. It is very efficient, but not drastic nor unsafe. Its use is contra-indicated whenever there is any inflammation, irritation, or congestion of the abdominal viscera; in hemorrhoids, and in irritation of the womb and menorrhagia. It is not at all so violent as aloes, yet is not a suitable agent in the cases named. Its griping effect is often very unpleasant to nervous temperaments; but this may be nearly obviated by combining it with the aromatics, as ginger or the spices, or with bitartrate of potassa. Its purgative effect is considerably increased when combined with the laxative tonics, as boneset, gentian, balmony, etc.
