ABSTRACT OF THE DISCLOSURE A process is described for extracting a pharmaceutically active polysaccharidic substance from the aloe plant. The process involves obtaining aloe juice having solubilized matter; adjusting the pH of the aloe juice to a range from about 3 to about 3.5; adding a water soluble, lower aliphatic polar solvent to the aloe juice to precipitate the active chemical substance. The water soluble, lower aliphatic polar solvent with the solubilized matter is removed and the precipitated active chemical substance is isolated. The pharmaceutically active polysaccharidic substance and its characteristic properties are described.
