Houseleek
Sempervivum tectorum
Long before it had a Latin name, houseleek was a fixture of the European cottage garden, prized less for eating than for having on hand. Its cool, mucilaginous leaf juice made it a household standby for soothing minor burns, scalds, and stings, the kind of everyday remedy a grandmother kept growing by the back step rather than in an apothecary jar. Medieval and folk tradition also planted it thickly on roofs, both for its odd hardiness in thin, dry soil and for the old belief that a living roof of houseleek warded off lightning strikes. That dual role, half practical remedy and half protective charm, made it one of the most widely cultivated plants of the pre-modern European home.

Traditional preparations.
The oldest and simplest use for houseleek, a split leaf pressed straight onto the skin. Cottage gardeners kept it near the kitchen door for exactly this reason.
Pick one fresh leaf, split it lengthwise with a clean knife or your thumbnail, and press the moist inner side directly onto a minor burn, sunburned patch, or insect sting. Hold or tape lightly in place for a few minutes and reapply with a new leaf as needed.
A quick way to spread the plant's cooling juice over a larger area, such as a mild sunburn, without needing a fresh leaf at hand for every inch of skin.
Crush two or three fresh leaves in a small dish to release the gel-like juice, then smooth it gently over the affected skin with clean fingers. Rinse off after 10 to 15 minutes.
Safety.
Houseleek is used topically, not taken internally. Patch test first since some people are sensitive to the sap, and keep it away from the eyes and deep or severe burns.
