PHA is a strong mitogenic source, it can activate the transformation of small lymphocytes into lymphoblasts, followed by division and proliferation, release of lymphokines; can increase the phagocytic function of macrophages; promote bone marrow hematopoiesis, increase the number of white blood cells; the virus attack The cells have killing effect and induce interferon effect; lectin can also agglutinate cancer cells and inhibit some
