Medicinal Uses
Astringent; Foot care; Hypotensive; Laxative; Rubefacient; Vermifuge; Vulnerary.

The herb is astringent, hypotensive, laxative, rubefacient, vermifuge and vulnerary[4, 7, 9, 13, 46]. It is considered to be a useful medicinal plant by some herbalists, though others do not use it because of the violence of its operation when taken internally[4, 7]. One of its best uses is as an effective and harmless corn-remover, it can also be used to bring boils to a head, though this can also cause some local irritation[7]. The bruised fresh plant is applied as a poultice to wounds and minor burns[9], though some care should be exercised because the plant can cause blisters or skin irritations[244]. The herb is difficult to dry and so is best used when fresh, it can be gathered at any time during the spring and summer[7].

A homeopathic remedy is made from the plant[9]. It is used in the treatment of piles and anal irritations[9].

The active principle of Sedum acre is an alkaloid, of which easy decomposibility has prevented chemical analysis.
     Jungst has investigated the action of the hydrochlorate and sulphate of the alkaloid, the freshly expressed juice and the alcoholic extract. The extract and the plant have no specific pharmacological properties. Cats are more sensitive to the alkaloid than dogs. The symptoms of an acute poisoning are: After a preceding stage of choking and vomiting, increasing anaesthesia and stupefaction appear; the voluntary movements of the [skeletal] muscles decrease progressively; the respiration becomes forced and superficial, the respirations decrease more and more in number; spasmodic movements of the extremities, with dyspnoea appear. Death takes place from cessation of respiration, the heart beating after the cessation. In cats, there were distinct mydraisis and photophobia, together with violent distortion of the bulb, outwards and upwards. The activity of the salivary glands, as well as that of the digestive tract, is excited. Applied locally, the freshly-expressed juice of the plant causes distinct and increasing burning, with a growing redness of the skin; the alcoholic extract is inactive in this direction. Upon man, there resulted violent headache, together with gastric disturbance [nausea, anorexia, etc.].
