Composition and method of treating cancer

Abstract

A pharmaceutical composition including tannic acid and tannin complexes, and a method of treating cancer with tannic acid and tannin complexes.

We claim:  
     
         1 . A pharmaceutical composition for the treatment of cancer comprising an effective amount of tannic acid or tannin complexes from the sap of a plant of the Musaceas Family and a pharmaceutically acceptable carrier.  
     
     
         2 . A pharmaceutical composition according to  claim 1 , wherein said plant of the Musaceas Family is selected from the group consisting of  Musa paradisiaca  (plantain);  Musa Cavendish Enano  (banana), varieties and mixtures thereof.  
     
     
         3 . A pharmaceutical composition according to  claim 1 , further comprising 30% honey.  
     
     
         4 . A pharmaceutical composition according to  claim 1 , wherein said composition comprises about 5-20% tannic acid.  
     
     
         5 . A pharmaceutical composition according to  claim 4 , wherein said composition comprises about 10% tannic acid.  
     
     
         6 . A pharmaceutical composition according to  claim 1 , wherein said effective amount of said pharmaceutical composition can strip N-acetyl neuraminic acid from a cancer cell surface allowing recognition of said cancer cell by the immune system in vivo comprising contacting said cancer cell with tannic acid or tannin complexes.  
     
     
         7 . A method of treating cancer comprising administering an effective amount of a pharmaceutical composition comprising tannic acid or tannin complexes from natural or synthetic sources.  
     
     
         8 . A method of treating cancer according to  claim 7 , wherein said tannic acid or tannin complexes from natural sources are extracted from the sap of a plant of the Musaceas Family.  
     
     
         9 . A method of treating cancer according to  claim 8 , wherein said plant of the Musaceas Family is selected from the group consisting of  Musa paradisiaca  (plantain);  Musa Cavendish Enano  (banana), varieties and mixtures thereof.  
     
     
         10 . A method of treating cancer according to  claim 7 , wherein said pharmaceutical composition comprises about 5-20% tannic acid.  
     
     
         11 . A method of treating cancer according to  claim 7 , wherein said pharmaceutical composition comprises about 10% tannic acid.  
     
     
         12 . A method of treating cancer according to  claim 7 , wherein said pharmaceutical composition is administered at least once daily.  
     
     
         13 . A method of treating cancer according to  claim 12 , wherein said pharmaceutical composition is administered four times daily.  
     
     
         14 . A method of treating cancer according to  claim 7 , wherein said cancer is selected from the group consisting of bladder, breast, kidney, leukemia, myeloma, liposarcoma, lymphoma, colon, penis, tongue, prostate and uterus cancers.  
     
     
         15 . A method of stripping N-acetyl neuraminic acid from a cancer cell surface allowing recognition of said cancer cell by the immune system in vivo comprising contacting said cancer cell with tannic acid or tannin complexes.  
     
     
         16 . A pharmaceutical composition according to  claim 1 , comprising 10% tannic acid, Sorbitol 70% Solution (20.9588%), Cremophor RH40 (partially hydrogenated castor oil)(8.8401%), Potassium sorbate (0.15%), Methylparaben (0.038%), and Propylparaben (0.013%) w/w.
