Description

Sempervivum caucasicum is a species of plant from the houseleek genus (Sempervivum) in the succulent family (Crassulaceae). Sempervivum is a genus of about 40 species of flowering plants in the family Crassulaceae, commonly known as houseleeks. Other common names include liveforever (the source of the taxonomical designation Sempervivum, literally "always/forever alive") and hen and chicks, a name shared with plants of other genera as well. They are succulent perennials forming mats composed of tufted leaves in rosettes. In favourable conditions they spread rapidly via offsets, and several species are valued in cultivation as groundcover for dry, sunny locations. Houseleeks exist from Morocco to Iran, through the mountains of Iberia, the Alps, Carpathians, Balkan mountains, Turkey, the Armenian mountains, in the northeastern part of the Sahara Desert, and the Caucasus. Their ability to store water in their thick leaves allows them to live on sunny rocks and stony places in the mountain, subalpine and alpine belts. Most are hardy to US zone 4, and will handle warm climates to about zone 9. It has been used historically and is used presently for purported health benefits. It has no known side effects (aside from being an emetic in large doses) or drug interactions. Common herbal uses are stopping bad cases of diarrhea by drinking the juice of the leaf or eating the leaves directly, and the juice is commonly applied directly to the skin for many of the same uses as aloe vera such as burns, warts and insect bites. It is furthermore said to bring relief in cases of swellings and water retention. The famous English herbalist Culpepper says 'Our ordinary Houseleek is good for all inward heats, as well as outward, and in the eyes or other parts of the body: a posset made of the juice is singularly good in all hot agues, for it cooleth and tempereth the blood and spirits and quencheth the thirst; and is also good to stay all deflection or sharp and salt rheums in the eyes, the juice being dropped into them. If the juice be dropped into the ears, it easeth pain. It cooleth and restraineth all hot inflammations St. Anthony's fire (Erysipelas), scaldings and burnings, the shingles, fretting ulcers, ringworms and the like; and much easeth the pain and the gout.
