Reishi mushroom (Ganoderma lucidum) is classified as an adaptogen, immune-boosting, and anti-inflammatory herb. It has been used for centuries in traditional Chinese medicine to promote overall health and longevity. Reishi is particularly known for its ability to support the immune system by enhancing the body's natural defense mechanisms. It is also used to reduce stress, improve sleep quality, and promote relaxation. Reishi has powerful antioxidant properties that help protect cells from damage and support heart health by promoting healthy blood pressure and cholesterol levels. Additionally, it has been used to improve liver function and support respiratory health. Reishi is typically consumed as a supplement, in tea, or as a tincture.
