All the green tea in the world will not prevent or stop the HIV virus.
In Vitro ( test tube) experiments DO NOT equal human studies. What can be accomplished in a lab is very often NOT achievable outside. This is a very simplistic explanation.
Once HIV is in your bloodstream and makes it's way to your lymphnodes( about 72) hrs.,it CAN NOT be eliminated for the body. It survives, reproduces and bonds with White Blood Cells destroying them.
