Red Reishi Mushroom Extract
Also known as: Reishi, Lingzhi, Ling chih, Ling zhi, Spirit plant, Ganoderma lucidum
Overview
Ganoderma lucidum, commonly known as Reishi or Lingzhi, is a fungus native to Asia celebrated in traditional medicine for its potential health benefits. It contains bioactive compounds such as polysaccharides and triterpenoids, which are believed to contribute to its health-promoting properties. Traditionally used for immune system support, cancer treatment, and cardiovascular health, the body of research reveals numerous studies; however, many have methodological flaws, limiting the quality and reliability of evidence supporting these claims. The extract is available in various forms, including capsules and fluid extracts, and its use has gained popularity as a dietary supplement, although more extensive clinical trials are necessary to substantiate its efficacy.
Benefits
Reishi may enhance immune function by increasing T-cell percentages (CD3, CD4, CD8) and has been associated with improved quality of life in cancer patients undergoing conventional treatment. Its adjunctive effects for cancer therapy have been observed, though evidence largely stems from small studies. Additionally, it might offer benefits for other conditions, such as chronic fatigue syndrome and lower urinary tract symptoms, as reported in limited research. Overall, while some benefits are suggested, the low quality of evidence restricts definitive conclusions and calls for further investigation into its clinical significance.
How it works
Reishi's bioactive compounds, particularly polysaccharides and triterpenoids, are thought to modulate immune responses and exhibit antioxidant properties. These compounds can interact with the immune system and potentially influence the cardiovascular and nervous systems. However, specific molecular targets and detailed pathways of action are yet to be fully elucidated, and data on absorption and bioavailability is limited.
Side effects
Ganoderma lucidum is generally regarded as safe, with mild side effects reported. Common adverse effects occurring in over 5% of users include dizziness, gastrointestinal upset, and skin irritation. Uncommon side effects affecting 1-5% of users may include dry mouth, nosebleed, and bone pain. There are rare reports of liver injury in less than 1% of users. Precaution is advised when used in combination with anticoagulants and antiplatelet drugs due to potential interactions. While no specific contraindications have been identified, its safety in pregnant and lactating women is unproven, warranting caution in these populations.
Dosage
While the minimum effective dose of Reishi has not been established, optimal dosages typically range from 6 to 12 grams of extract per day. There are no defined maximum safe doses, but patients should consider individual health conditions and responses. No specific timing for administration is recommended, and Reishi is available in various forms, which may impact absorption. Due to the limited understanding of its pharmacokinetics, users should be cautious and mindful of individual health status.
