Reishi is a woody fungus that has been used in traditional Asian medicine for centuries, and it's increasingly available in Western supplements and wellness products. You'll find it sold as capsules, powders, teas, and extracts, often with claims about stress relief, sleep, and immune function. This category explores what reishi actually is, what the research shows about how it works in the body, and where the evidence is strongest versus where questions remain.
The articles here address practical questions: what compounds in reishi are thought to be active, what human studies have found compared to animal research, how it's typically used, and what you should know about quality and safety. You'll learn the difference between established effects supported by clinical trials and emerging claims that need more investigation.
