Reishi medicinal

Reishi (Ganoderma lucidum) is a medicinal mushroom widely used in traditional Chinese medicine, known for its immune-modulating and adaptogenic properties.

About this subject

Reishi, scientifically known as Ganoderma lucidum, is a basidiomycete fungus that grows on the trunks of deciduous trees, especially oaks and maples. In traditional Chinese medicine, it is called lingzhi and is regarded as one of the most important adaptogens, used for over two millennia to promote longevity and vitality. Its distinctive appearance includes a shiny, reddish-brown kidney-shaped cap and a woody texture.

In Brazil, reishi cultivation has expanded, particularly in temperate regions such as the South and Southeast. The fungus is sold in capsules, extracts, and teas. Scientific studies indicate that its polysaccharides (beta-glucans) and triterpenes (ganoderic acids) modulate the immune system, have anti-inflammatory effects, and may help control oxidative stress.

Interestingly, reishi is not consumed raw due to its hardness and bitter taste. Traditionally, it is boiled in water to extract active compounds. In 2019, global production of reishi exceeded 50 thousand tons, led by China, Japan, and South Korea. The species is also a focus of integrative oncology research, though clinical trials remain limited.
