Stonecrop (Sempervivum tectorum L.)
DID YOU KNOW?
Common houseleek is a perennial and evergreen succulent with leaves formed around each other in a rosette, found throughout Europe on sunny rocks and rocky soils. The leaves may have a conspicuous apical spot or may be without any pattern. According to folk belief, Sempervivum growing on the roof deters lightning and as Jupiter is considered the god of lightning, the plant has been called Jupiter's beard since ancient times.
Folk medicine used the sap squeezed from the leaves for treating minor wounds, burns, inflammations and insect bites or mixed in wine for bringing down fever, while its decoction was used for bronchitis, sore throat, aphtha and sore lips.
The beauty industry uses it as a skin conditioner. Due to its active ingredients it is effective for treating sensitive, sunburnt, hyper-pigmented or lentiginous skin. Skin care products containing sempervivum have keratoplastic, astringent, regenerating, soothing and bleaching effects.
