Linh Chi, also known as Reishi mushroom or Ganoderma lucidum, is a medicinal fungus prized in traditional medicine, particularly in Chinese medicine. It is recognized for its potential health benefits, including boosting the immune system, reducing stress, and promoting longevity. The mushroom has a distinctive glossy appearance and is often found growing on decaying wood. Linh Chi is typically consumed in various forms, such as powders, teas, or capsules. Its active compounds, including triterpenes and polysaccharides, are believed to contribute to its therapeutic properties. While many people use it for wellness, scientific research is ongoing to fully understand its effects.
