Aloes is the inspissated juice of the leaves of the Aloe Socotrina, and contains a bitter precipitate known as aloin, and also a volatile oil, to which its odor is due. Its preparations are purified aloes - aloe purificata; watery Extract of Aloes - Ex-tractum Aloes Aquosum; Tincture of Aloes - Tinctura Aloes; also a number of pilular forms, and a tincture combined with myrrh - Tinctura Aloes et Myrrhae, and wine of aloes - Vinum Aloes. Purified Aloes is in the form of pieces of a dull or reddish-brown color, very brittle and soluble in alcohol, and a very bitter and disagreeable taste.

Medical Properties And Physiological Action

Aloes is a stomachic tonic and purgative, being principally employed for the latter effect. In large doses its action is that of a powerful purgative, and hence it is contraindicated in irritable or inflammatory conditions of the stomach. It stimulates the functions of the liver, and increases the flow of bile as well as the intestinal secretions generally. Its chief effects are on the large intestine, increasing its peristaltic movement, and causing tormina and tenesmus with heat and irritation of the rectum. It also increases the menstrual flow and the blood supply of the pelvic organs. It requires some ten or twelve hours to produce its cathartic effects. A purgative action may be induced by applying it to an exposed surface. In moderate laxative doses the stools are not liquid and but slightly altered in character. It is commonly administered in small doses in combination with nux vomica.

Therapeutic Uses

Aloes is very efficient in constipation dependent on weakness of the muscular layer of the large intestine. It is also employed in jaundice, atonic dyspepsia, hemorrhoids without active pelvic congestion, amenorrhcea dependent upon anaemia, menorrhagia in debilitated conditions, gonorrhoea, catarrh of uterus, etc.
