Ganoderma is a genus of fungi known for its distinctive shiny, reddish-brown caps and woody texture. Commonly referred to as reishi or lingzhi, these mushrooms have been used in traditional medicine for centuries, particularly in Chinese medicine. They are often found growing on decaying wood and are recognized for their potential health benefits. Research suggests that Ganoderma may have immune-boosting properties and could help reduce stress and improve sleep quality. The mushrooms contain bioactive compounds, including triterpenes and polysaccharides, which are believed to contribute to their therapeutic effects. However, more studies are needed to fully understand their benefits.
