Lingzhi (Ganoderma lucidum), also known as reishi, is a medicinal mushroom long used in traditional Chinese medicine. Its application for combating free radical damage is primarily supported by scientific studies. Lingzhi is rich in bioactive compounds, such as polysaccharides, triterpenoids, and phenolic compounds, which exhibit antioxidant properties. Laboratory and animal studies have demonstrated that these compounds can scavenge free radicals, reduce oxidative stress, and enhance endogenous antioxidant enzyme activities like superoxide dismutase (SOD) and glutathione peroxidase (GPx). For example, research published in peer-reviewed journals has shown that extracts of Ganoderma lucidum can protect cellular components from oxidative damage and modulate pathways involved in oxidative stress.

However, while in vitro and animal studies are promising, clinical evidence in humans remains limited. Some small-scale human trials suggest potential antioxidant benefits, but larger, well-controlled studies are needed to confirm efficacy and determine optimal dosage. Historically, lingzhi has been used to promote longevity and vitality, which could be attributed, at least in part, to its antioxidative effects. Thus, while scientific evidence supports the antioxidant and free radical scavenging properties of lingzhi, the direct clinical relevance for treating or preventing oxidative stress-related diseases in humans requires further substantiation.
