Aloes are succulents that have been used for centuries to soothe skin and treat a variety of ailments. They are known for their thick, fleshy leaves and their ability to store water in arid climates. Aloes are native to Africa, Madagascar, and the Arabian Peninsula, but they can now be found in many parts of the world. The gel from the leaves is often used topically to treat burns, cuts, and other skin irritations. It can also be taken orally to help with digestion and boost the immune system.
