Lingzhi, also known as Reishi mushroom, is a medicinal fungus that has been used in traditional Chinese medicine for thousands of years. It is known for its potential health benefits, including boosting the immune system, reducing stress, and improving sleep quality. The mushroom typically has a glossy, reddish-brown appearance and grows on decaying wood. Lingzhi contains bioactive compounds such as triterpenes and polysaccharides, which are believed to contribute to its health-promoting properties. It is often consumed in the form of teas, extracts, or capsules. While many people use it for wellness, scientific research is ongoing to fully understand its effects.
