Patent ID: 7494657

Claim:
A method for treating a human infected with human immunodeficiency virus (HIV), comprising: (a) inoculating Lentinus edodes fungus in a solid culture medium comprising 90 parts by weight of bagasse and 10 parts by weight of rice bran to yield proliferated mycelium; (b) disentangling the solid culture medium containing the proliferated mycelium so that the amount of the bagasse of 12-in mesh is not more than 30% by weight and adding thereto 1 to 10 kg of water and 0.5 to 5 g of at least one enzyme selected from the group consisting of cellulase, protease and glucosidase based on 1 kg of the disentangled solid culture medium, while keeping the solid culture medium at 30 to 50° C., to give a bagasse-containing mixture; (c) grinding and milling the bagasse-containing mixture so that the amount of the bagasse of 12-in mesh is not less than 70% by weight; (d) heating the ground and milled bagasse-containing mixture to a temperature of 75 to 95° C. to inactivate the enzyme; (e) filtering the resultant mixture through a filter cloth of 50 to 120-in mesh to thereby obtain a purified, concentrated pharmaceutical Lentinus edodes mycelium extract; and (f) administering orally at least one effective dose of said purified, concentrated extract to said human, wherein said extract weakens HIV activity and inhibits HIV proliferation in said human.
