According to the research published in Food & Functions recently, a team led by Prof. Huang Qing at the Institute of Intelligent Machines, Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), reported for the first time an update and a comprehensive summary of the studies on the immunomodulatory therapies and nutritional significance of Ganoderma lucidum (G. lucidum) from 2010 to 2022, and confirmed that G. lucidum is an essential prebiotic for increasing bacterial flora and a health encouraging agent because of its components, primarily its abundant source of polysaccharides, triterpenoids, and polyphenols.
The study concluded that, the adoption of standard pharmaceutical methods for the safety assessment, quality assurance, and efficacy testing of G. lucidum-derived compounds will be the gateway to bringing them into health establishments.
With a long history in traditional Chinese medicine, G. lucidum is a mushroom species suggested to improve health and extend life, and is evidenced to be effective in the prevention and treatment of various metabolic disorders. Although certain bioactivities and bioactive compounds of G. lucidum have been recently reviewed, till date, none has critically analyzed and collated their mechanism of actions.
The literature reported in this study was mainly collated from PubMed, Scopus databases, Web of Science Core Collection, and Google Scholar from 2010-2022, with the focus on the recent advances in defining its immunobiological mechanisms, prebiotic merits for gut health and sleep, and possible application in the nutraceuticals, cosmeceuticals, food and pharmaceutical industries as well as the safety and efficacy of G. lucidum bioactive compounds (emphasis on polysaccharides, triterpenoids and phenolic compounds), since these are essential in the prevention and management of chronic diseases.
Furthermore, G. lucidum was found to encourage the balance of the gut microbiota, boost and regulate the immune system. This activates a set of defense mechanisms that responds swiftly to invading or attacking pathogenic microbes and also played a key role in initiating and maintaining specific immunity. Hence, augmenting the body's natural immunity greatly impacts the body's overall immune function.
