Ophiocordyceps sinensis has traditionally been used to treat respiratory disorders including asthma and serum markers of airway inflammation were seen to be reduced in patients with mild asthma given O. sinensis capsules1. O. sinensis also improved lung function in sensitized guinea pigs and reduced airway inflammation in sensitized rats2. An in vitro study on human airway epithelial cells showed O. sinensis and its components to alter ion transport and regulate Th1/Th2 balance3-5.
Ganoderma lucidum has also traditionally been used to treat asthma and its triterpenoid components are known to have strong anti-inflammatory and anti-histamine activity. Research on a closely related species, Ganoderma tsugae, in murine models of allergic asthma shows that triterpenoid extracts reduce bronchoalveolar inflammation and attenuate Th2 responses without overall immunosuppressive effects6,7. In addition, mushroom polysaccharide extracts are known to shift immune balance away from Th2 dominance and towards Th1 dominance and have been shown to help correct a skewed Th1/Th2 balance in an animal asthma model, indicating their potential in the management of this condition, as well as other allergic disorders8.
O. sinensis mycelial biomass combines well with triterpene-rich or triterpene/polysaccharide extracts from G. lucidum to treat a wide range of lung disorders. 3g/day O. sinensis mycelial biomass with 1-3g/day G. lucidum extract.
