What causes thunderstorms? Thunderstorms form when an air mass becomes so unstable that it overturns (convects) violently. Unstable means that the air in the lowest layers is unusually warm and humid, or that the upper layers are unusually cool, or oftentimes, both.
Aloe is the name of a plant genus that contains more than 300 species. Most of the aloe species are native to Africa, Madagascar and the Arabian Peninsula. In addition to the familiar cactus-like plant called aloe vera that many people use to soothe sunburns and other skin ailments, this genus has plants that range from grassy succulents to large trees.
Aloe is a plant originally from Africa. The long, green leaves contain aloe gel and a sticky yellow residue called latex. The gel is the part of the aloe plant used most commonly, both topically and orally. Aloe latex (also known as drug aloe) contains anthraquinone gycosides, constituents that have strong laxative effects, so it is rarely found in commercial laxative products.
