Ganoderma lucidum shows excellent results in the management of allergic rhinitis, its polysaccharides suppressing the pro-inflammatory, Th2-mediated immune state responsible for the hypersensitivity to the particular allergen(s) while several of its triterpenoid ganoderic and lucidenic acids have direct anti-inflammatory and anti-histamine action1-6. It thus addresses both the symptoms and the underlying imbalance of the condition and can be used in either a prophylactic or therapeutic mode.
Biomass is often effective in mild cases while triterpene-rich extracts have stronger anti-histamine activity for more severe cases (1-3g/day).
