Aloin, also called barbaloin, is a yellow-brown or light yellow green powder with a bitter taste, is mainly used for improving immunity, inhibiting bacteria, protecting the liver and skin.  Aloin powder is easily soluble in organic solvent and slightly soluble in water. Aloin powder is produced from fresh aloe leaves through juicing, colloid milling, centrifugal filtration, concentration, enzymolysis and purification.
Rhein powder soluble in an organic solvent but insoluble in water has antibacterial, anti-inflammatory and anticancer properties.
