Reishi Fruiting Body Extract

Also known as: Ganoderma lucidum (Leysser ex Fr.) Karst, Reishi, Lingzhi, Ling chih, Ling zhi, Spirit plant, Ganoderma lucidum

Overview

Ganoderma lucidum, commonly known as Reishi, is a fungus native to Asia with a long history of use in traditional medicine. It is recognized for its potential health-promoting properties and has been used for centuries to support overall well-being and longevity. Reishi contains a variety of bioactive compounds, including polysaccharides and triterpenoids, which are believed to contribute to its therapeutic effects. It is available in various forms, such as whole mushroom, extracts, and powders. While research into Reishi's pharmacological effects is ongoing, it is primarily used for its potential to support the immune system, reduce stress, and improve overall health. The quality of available evidence is variable, with some studies showing promise, but more rigorous clinical trials are needed to confirm its benefits.

Benefits

Reishi mushroom has potential anticancer and immunostimulatory effects, primarily attributed to its polysaccharide content. Some studies suggest it may reduce fatigue and improve antioxidant status, although results are mixed. Secondary benefits may include cardiovascular support, liver protection, and antiviral activity. While traditionally used for general health, evidence for specific populations is limited. Clinical significance and effect sizes are not well-quantified due to variability in study designs and outcomes. More research is needed to fully understand the extent and reliability of these benefits.

How it works

Reishi's mechanism of action involves immune modulation, antioxidant activity, and potential anti-inflammatory pathways. It interacts with the immune system, liver, and cardiovascular system. Polysaccharides and triterpenoids are key bioactive compounds that may influence these pathways. However, the precise molecular targets and mechanisms are not fully elucidated. Limited data exists on the absorption and bioavailability of Reishi's active compounds, making it difficult to fully understand how it works within the body.

Side effects

Reishi mushroom is generally considered safe, but some side effects have been reported. Common side effects (occurring in more than 5% of users) include dizziness, gastrointestinal upset, and skin irritation. Uncommon side effects (1-5%) are not well documented. Rare side effects (less than 1%) are infrequent, with few reports of toxicity. Reishi may enhance the effects of anticoagulants and antiplatelet agents, increasing the risk of bleeding. Caution is advised for individuals with bleeding disorders. Limited data exists on the safety of Reishi during pregnancy and lactation. It is important to consult with a healthcare provider before using Reishi, especially if taking medications or with pre-existing health conditions.

Dosage

Optimal dosage ranges for Reishi mushroom are not well-established. Typical dosages range from 1.5 to 9 grams per day for whole mushroom, with extracts used at lower doses. The minimum effective dose and maximum safe dose are not well defined. There are no specific timing recommendations for Reishi consumption. Dried extracts are commonly used. Limited data is available on absorption factors and required cofactors. Due to the lack of comprehensive data, it is important to consult with a healthcare provider to determine an appropriate dosage.
