Aloe emodin

Aloe emodin (1,8-dihydroxy-3-(hydroxymethyl)anthraquinone) is an anthraquinone and a variety of emodin present in aloe latex, an exudate from the aloe plant. It has a strong stimulant-laxative action.[1] Aloe emodin is not carcinogenic when applied to the skin, although it may increase the carcinogenicity of some kind of radiation.[2][3]
