Disclosed are a pharmaceutical grade polysaccharide and a pharmaceutical composition thereof for use in the treatment of medical conditions associated with inflammation and fibrosis, and cancer associated with abnormal expression or increased expression of galectin protein. An arbitrary number of side chains, for example, mainly 1,4-β-D-galactose (the backbone is mainly a 1,4-linked galacturonic acid (GalA) moiety and fewer backbone components). Gal) and 1,5-α-L-arabinose (Ara) residues, alternatively consisting of alternating 1,4-linked (GalA) moieties and 1,2-linked rhamnose (Rha) A depolymerized composition comprising branched galactoarabino-rhamnogalacturonate.
