Study highlights therapeutic importance of Ganoderma lucidum

Researchers led by Prof. Huang Qing from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences reported for the first time an update and a comprehensive summary on the immunomodulatory therapies and nutritional significance of Ganoderma lucidum (G. lucidum) from 2010 to 2022, confirming that G. lucidum is an essential prebiotic for increasing bacterial flora and a health-promoting agent due to its components, especially its abundant source of polysaccharides, triterpenoids, and polyphenols.

The study was published in Food & Functions.

The researchers 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 their introduction into health care facilities.

With a long history in traditional Chinese medicine, G. lucidum is a mushroom species suggested to improve health and prolong life, and has been shown be effective in the prevention and treatment of various metabolic disorders. Although certain bioactivities and bioactive compounds of G. lucidum have been recently reviewed, to date, none has critically analyzed and summarized their mechanism of action.

The literature reported in this study was mainly collected from PubMed, Scopus databases, Web of Science Core Collection, and Google Scholar from 2010 to 2022, with a focus on the recent advances in the definition of its immunobiological mechanisms, prebiotic benefits for gut health and sleep, and potential application in the nutraceutical, cosmeceutical, food and pharmaceutical industries, as well as the safety and efficacy of G. lucidum bioactive compounds (focus on polysaccharides, triterpenoids and phenolic compounds), as these are essential in the prevention and management of chronic diseases.

In addition, G. lucidum has been shown to promote the balance of the gut microbiota, boosting and regulating the immune system. This activates a number of defense mechanisms that respond rapidly to invading or attacking pathogenic microbes and also play a key role in initiating and maintaining specific immunity. Hence, augmenting the body's natural immunity has a major impact on the body's overall immune function.
