Various parts of this mushroom, namely the mycelia, spores, and fruit body possess medicinal properties. The major physiologically active constituents in G. lucidum are polysaccharides, peptidoglycans, and triterpenes. Periodontitis is a disease that affects the tooth-supporting tissues and is characterized by a loss of periodontal attachment including the alveolar bone. The etiology of the disease is multifactorial and bacterial deposits play an essential role in the pathogenesis. The bacteria comprises predominantly of Gram-negative anaerobic rods.
