Acupuncture can stimulate and balance the immune system. Billions of B cells are on guard. Each recognizes only one specific invader or antigen. B cells catch the antigen or invader and engulf it. Helper T cells come to help and attach to the B cells releasing interleukins.
Interleukins are chemicals that make the B cells become an antibody factory.
Antibody factories are called plasma cells. Latch onto toxic substances that bacteria produce and inactivate these toxic substances. Coat the bacteria. This action attracts other immune cells to destroy the invaders. Latch onto a virus so the virus cannot infect the body's cells.
