Aloe is a genus of succulent perennial plants in the Liliaceae family characterized by fleshy green leaves arranged in a rosette formation along the stem. Aloe vera (synonym: Aloe barbadensis Mill.) is a species of the genus Aloe, alongside other species such as Aloe ferox (bitter aloe) and Aloe arborescens.[3]
Commercially, Aloe vera is available in three main forms: Aloe vera gel, Aloe vera latex, and Aloe vera juice (or whole leaf extract). The latter of these contains both the gel and the latex and should not be confused with Aloe vera beverages sold in stores, which typically contain Aloe vera diluted in water or juice (e.g., grapefruit).[3] While it is widely recognized for its topical application to alleviate pain from burns, Aloe vera is also used in cosmetic, food, and pharmaceutical products.[3]
