RESEARCH SUMMARY: Reishi Mushroom
KEY FINDINGS:
Cardiovascular Risk Factors in Metabolic Syndrome
- A 16-week double-blind, randomized, placebo-controlled trial assessed the efficacy of Ganoderma lucidum in treating hyperglycemia and other cardiovascular risk factors in individuals with type 2 diabetes mellitus and metabolic syndrome.
- 84 participants were divided into three groups: Ganoderma lucidum, Ganoderma lucidum with Cordyceps sinensis, or placebo, receiving 3 g/day of the respective treatments.
- The study found no significant effects of Ganoderma lucidum on primary outcomes (HbA1c and fasting plasma glucose) or secondary outcomes (blood pressure, triglycerides, waist circumference, BMI, etc.).
- No overall increased risk of adverse events was observed with Ganoderma lucidum treatment.

Quality of Life in Non–Small Cell Lung Cancer Patients Undergoing Chemotherapy
- A phase II randomized, double-blind, placebo-controlled clinical trial evaluated the preliminary efficacy and safety of Reishi & Privet Formula (RPF) in maintaining quality of life among patients with non–small cell lung cancer (NSCLC) undergoing chemotherapy.
- 82 participants were randomly assigned to receive either RPF (3.36 g/day) or placebo daily for 6 weeks.
- The RPF group showed a non-statistically significant trend towards higher quality of life scores compared to the placebo group, with better general health and emotional well-being.
- Adverse event rates did not differ between the RPF and placebo groups.

Lower Urinary Tract Symptoms in Men
- A double-blind, placebo-controlled, randomized, dose-ranging study evaluated the safety and efficacy of an ethanol extract of Ganoderma lucidum in men with slight-to-moderate lower urinary tract symptoms (LUTS).
- 88 men over the age of 49 were randomly assigned to receive either 6 mg of Ganoderma lucidum extract or placebo once daily for 12 weeks.
- The Ganoderma lucidum group showed a significant improvement in the International Prostate Symptom Score (IPSS) compared to the placebo group, with a mean difference of -1.18 points.
- No significant changes were observed in quality of life scores, peak urinary flow, mean urinary flow, residual urine, prostate volume, serum prostate-specific antigen, or testosterone levels.
- The treatment was well tolerated with no severe adverse effects reported.

RESEARCH QUALITY ASSESSMENT:
- All three studies were randomized, double-blind, placebo-controlled trials, which are considered the gold standard in clinical research.
- Sample sizes varied, with the largest study including 88 participants, which may limit the generalizability of the findings.
- While the studies were well-designed, some reported non-statistically significant trends, indicating the need for larger, more adequately powered trials to confirm efficacy.
- Future research should focus on larger sample sizes and longer follow-up periods to better assess the long-term effects and safety of Ganoderma lucidum.
