The immune system serves as a form of defense against the invasion from any foreign bodies. Any alteration in the form of infection, allergies and other immune diseases impairs the system making the body more susceptible to serious and even deadly diseases. Immunologic disorders are just some of the diseases that require sophisticated and complex treatment procedures. The EGCG in green tea has been highlighted in a medical journal to prevent various kinds of infection, particularly a virus that causes HIV. The EGCG exerts its inhibitory effect by competing with viruses that binds to CD4 T-cell receptors. HIV viruses are known to depress the CD4 T-cell count, making the HIV fall into AIDS or Acquired Immunodeficiency Syndrome, which is characterized by comprehensive dysfunction of the immune system. The competition between EGCG in green tea and HIV virus prevents the HIV glycoprotein envelope from binding to CD4 molecule, protecting CD4 T-cells from lowering down. A study conducted in Tokyo, Japan offered detailed information as to the use of EGCG for clinical application as an anti –HIV drug. An Egyptian study concluded that EGCG potentiates the effects of antibiotic as it has a synergistic effect on the drug. Currently, additional studies are being conducted to determine possible preventive effects of EGCG for HIV infection and they open a new perspective for HIV treatment. Many of these studies offer promising results.
Multiple Sclerosis (MS) is an autoimmune disease that affects the myelin sheath in the brain and in the spinal cord. An autoimmune disease is a condition wherein the own soldiers of the body fights and destroys the normal body cells because of its inability to recognize the normal form the abnormal ones. Multiple sclerosis is characterized by remission and exacerbation and comprehensive treatment must be employed to augment the individuals physical functioning. Complementary as well as alternative therapies are also suggested to be included in the treatment plan. The diet of the person with MS should be rich in antioxidants, like fruits, green leafy vegetables and of course green tea as a beverage. People suffering from MS, may benefit from EGCG in green tea by preventing permanent tissue damage and disability. EGCG has both neuroprotective and anti-inflammatory property, characteristics that are needed to achieve best therapeutic result from multiple sclerosis. The recommended dosage is a standardized extract of 250-500 mg of green tea daily. Multiple Sclerosis is common to genetically predisposed individuals and dietary factors like inclusion of green tea in the diet greatly reduces the risk for manifesting the disease.
