Reishi mushroom (Ganoderma lucidum) has been used in traditional East Asian medicine for centuries and continues to attract modern scientific interest. Research suggests that its bioactive compounds, particularly triterpenes and polysaccharides, may support immune function by modulating the activity of white blood cells, while also offering antioxidant and anti-inflammatory properties. Studies indicate potential benefits for liver health, stress relief, and sleep quality, with some preliminary research exploring its role in cancer risk reduction through immune-enhancing pathways. Commonly available as fruiting body extracts, spore powders, or dual extracts standardized to key active compounds, reishi is widely regarded as an adaptogenic supplement, though the strength of evidence varies across its studied uses and further clinical trials are needed to fully understand its effects.
