Desert Harvest grows their aloe organically and then uses the whole aloe leaf. Proprietary processes dissolve the cellulose, eliminate contaminants, and remove the anthraquinones, which can cause diarrhea. A patented freeze-drying process is used to remove excess water without altering or destroying the polysaccharides, vitamins, minerals, amino acids, and enzymes present in the plant. No artificial ingredients and no acid additives are used in the final product.
