Overview

Aloe, a plant, produces two substances used in health care products — clear gel and yellow latex.

People primarily use aloe's clear gel topically in creams and ointments to treat burns, the skin condition psoriasis and even acne. Some also take the gel orally to treat certain conditions. Aloe latex, a laxative, has been taken orally to treat constipation.

While aloe gel is generally safe when used as recommended, oral use of aloe latex poses safety concerns. In fact, taking 1 gram a day of aloe latex for several days can cause kidney damage and might be fatal.
