Yunzhi has been used in traditional Chinese medicine for centuries to strengthen the body's immune system.

More recent scientific researches and clinical trials have proven that Yunzhi extract helps stimulate the immune system so that the body is better able to defend against the serious illness.

Yunzhi is an effective complementary treatment option for people with serious illness at various stages.

The main effects of Yunzhi (Coriolus Versicolor) published in research reports include:

1. Activation of immune cells such as: T-lymphocytes, B-lymphocytes, monocytes, macrophages, bone marrow cells, natural killer cells and lymphokine- activated cells.
2. Increase of antibodies and a variety of cytokines such as: interleukin -2, interleukin -6, interferon and TNF.
3. Restore immunological response depression derived from serious illness treatment back to normal level.
4. Enhance the body’s immunity to reduce chance of infection.
5. Reduce the side effects of the treatment of serious illness, improve patient’s mental and health status.
6. Inhibit mutated cells proliferation.
7. Increase the survival rate of patients.
