Ganoderma lucidum (Reishi or Ling-zhi), a popular medicinal mushroom, is regarded by the Chinese as “mushroom of immortality”. It is believed that regular consumption of Ganoderma lucidum in the form of tea or mushroom powder can preserve the human vitality and promote longevity1. Scientific investigations have been conducted to show its anti-cancer, hypoglycemic and immuno-modulating effects. Its bioactive components comprise of triterpenes, polysaccharides and immune-modulatory proteins.
Anti-tumour activities are mediated through stimulation of spleen-cell proliferation and expression of cytokines such as interleukins Iand IIand IFN γ. 2
Β-D-glucan polysaccharides stimulate or modulate the immune system by activation of macrophages and helper T-cells, as well as increase the immunoglobin levels to produce a heightened response to foreign cells. 3
Possible mechanism may be due to stimulation of insulin release from the islets directly, through facilitation of Ca2+ inflow to the pancreatic cells.4
Enhanced innate immunity by promoting function of macrophages, B and T lymphocytes, and dendritic cells.5
