Aloe vera refers to the gel in the centre of the leaf of Aloe vera plants. However some preparations may be homogenized whole leaf extracts, which also contain aloes, the laxative substance found in the bitter, yellow juice which is also contained in the leaf.
Studies have found the gel to be effective against first- and second-degree burns, radiation burns, skin ulcers and peptic ulcers.
