Rating (out of 5): 2

Ganoderma lucidum, also known as Reishi mushroom or Lingzhi, has a long history of use in traditional Chinese medicine (TCM) for supporting immune function and combating a variety of ailments, including respiratory infections and the common cold. Historical texts and TCM practitioners have recommended Ganoderma as a general tonic to strengthen the body's resistance to illness, and it is often included in herbal formulations intended to help with colds and flu-like symptoms.

From a scientific perspective, Ganoderma contains bioactive compounds such as polysaccharides, triterpenoids, and peptidoglycans, which have demonstrated immune-modulating and potential antiviral effects in vitro and in animal models. Some laboratory studies have suggested that extracts from Ganoderma can inhibit the replication of certain viruses and enhance the activity of immune cells, such as macrophages and natural killer cells. However, robust clinical trials in humans specifically evaluating its effectiveness for preventing or treating the common cold are lacking.

Therefore, while there is a strong traditional basis for using Ganoderma to support the body during colds, and some preliminary scientific rationale, the direct evidence for its efficacy in treating or preventing colds in humans remains limited. More rigorous human studies are needed to confirm its antiviral benefits in this context.
