Dossier Reishi: Libido

Zelfs het libido schijnt bij mannen omhoog te gaan, zo’n 1-2 uur na inname van 1-2 Reishi Sporen olie capsules, een opmerkelijke ervaring!

Notabene een op leeftijd zijnde man van 93 meldt dat hij weer erecties kreeg!

Toelichting Ganoderma lucidum (Reishi) werd getest in mannen met lichte-tot-matige problemen van de urine-wegen.

Een vooraanstaand instituut in Amerika zegt hierover:

Lower Urinary Tract Symptoms (LUTS)
LUTS is common in older men and usually involves problems with bladder filling or voiding. In a randomized, placebo-controlled clinical study, 88 men with slight-to-moderate LUTS were given a Reishi extract (6 mg daily) or placebo for 12 weeks. Reishi extracts more greatly improved LUTS than the placebo. Also, no severe adverse effects were reported. Larger, long-term studies are needed to see if Reishi extracts can improve urinary flow in men with more severe LUTS.

Literature Summary and Critique

Noguchi M, et al. Randomized clinical trial of an ethanol extract of Ganoderma lucidum in men with lower urinary tract symptoms. Asian J Androl. Sep 2008;10(5):777-785.
Because G. lucidum extracts have shown variable 5 alpha-reductase inhibition, 88 men with slight-to-moderate lower urinary tract symptoms (LUTS) were given the G. lucidum extract (6 mg daily) that maximally inhibited 5 alpha-reductase or placebo for 12 weeks. Improvements in LUTS as assessed by the International Prostate Symptom Score (IPSS) and urine flow variables were determined. In addition, prostate volume, residual urinary volume after voiding, and adverse effects were also measured. Participants who received the G. lucidum extract had improved IPSS as compared to the placebo group. In addition, no severe adverse effects were reported. Larger, long-term studies are required to determine if G. lucidum extracts could further improve LUTS as well as urinary flow in men with more severe LUTS.

Reishi (Ganoderma lucidum):

Red reishi, commonly known as LingZhi in Chinese, is a mushroom thought to have many health benefits. In a re­search study exploring the anti-androgenic effects of 20 species of mushrooms, reishi mushrooms had the stron­gest action in inhibiting testosterone (Ref. Fujita et al, 2005). That study found that reishi mushrooms significantly reduced lev­els of 5-alpha reductase, preventing conversion of tes­tosterone into the more potent DHT. High levels of DHT are a risk factor for conditions such as benign prostatatic hypertrophy (BPH), acne, and baldness.
