Great quality product

Marci WicksOctober 26, 2023

I first ordered the Reishi through the manufacturer's website but saw that I could have it delivered sooner through Amazon. This is my second bottle I ordered along with Lions Mane from Host Defense. I have noticed that I am calmer, my mind is functioning better and my mental health has improved so I am going to stick with this. I also bought these both for my father who is struggling with cognition and hoping it will help improve his health. On a side note, I do work for a vitamin company so I am cautious where I purchase supplements from due to my knowledge of working in quality supply side of the industry. Read more

Red Reishi for Speech delays

MizmeltApril 27, 2015

This little wonder mushroom is awesome! it was recommended to me for speech delays. I cant start to tell on the improvement of quality of life this has offered to my child on the Autism spectrum... First, when he began to take it, he hardly spoke, he barely slept at night, and was quite sickly considering he's in daycare and gets germs from his little classmates. After 2 weeks of daily use, he began to expand his vocabulary, now after about 4 months of use he's almost fully verbal, with that his temper has improved as he doesn't get as frustrated as before because he can verbally express his needs and wants. His sleep has increased as well, for 3 years he would normally wake up 2-3 times at night and struggle with falling asleep... being that I'm a single mommy, it was tiring because I work full time, but now, he is able to fall asleep much faster, and stay asleep, the thing I thought would never happen with me. And as far as his health, I can tell you that my oldest son gets sick, I have been sick, and I'm sure his little classmates have brought to daycare quite the cocktail of germs and viruses, but he has been clear of any illnesses. I'm super happy to have found out about reishi and would recommend it to anyone. I was told to use half the capsule on a drink, but he was still taking a bottle at the time, so I used the whole capsule on his night bottle, because a good amount of it didn't come out through the nipple, and he perhaps got about 3/4ths at most. For some children it may take up to a month to see results, as everyone is different. I began to see results in 2 weeks. Read more

Wiki info...

Zoe WintersApril 13, 2013

Research and therapeutic usage: Lingzhi may possess anti-tumor, immunomodulatory and immunotherapeutic activities, supported by studies on polysaccharides, terpenes, and other bioactive compounds isolated from fruiting bodies and mycelia of this fungus (reviewed by R. R. Paterson[17] and Lindequist et al.[43]). It has also been found to inhibit platelet aggregation, and to lower blood pressure (via inhibition of angiotensin-converting enzyme[44]), cholesterol, and blood sugar.[45] Laboratory studies have shown anti-neoplastic effects of fungal extracts or isolated compounds against some types of cancer, including epithelial ovarian cancer.[46] In an animal model, Ganoderma has been reported to prevent cancer metastasis,[47] with potency comparable to Lentinan from Shiitake mushrooms.[48] The mechanisms by which Ganoderma lucidum may affect cancer are unknown and they may target different stages of cancer development: inhibition of angiogenesis (formation of new, tumor-induced blood vessels, created to supply nutrients to the tumor) mediated by cytokines, cytoxicity, inhibiting migration of the cancer cells and metastasis, and inducing and enhancing apoptosis of tumor cells.[17] Nevertheless, Ganoderma lucidum extracts are already used in commercial pharmaceuticals such as MC-S for suppressing cancer cell proliferation and migration. Additional studies indicate that ganoderic acid has some protective effects against liver injury by viruses and other toxic agents in mice, suggesting a potential benefit of this compound in the treatment of liver diseases in humans,[49] and Ganoderma-derived sterols inhibit lanosterol 14α-demethylase activity in the biosynthesis of cholesterol .[50] Ganoderma lucidum compounds inhibit 5-alpha reductase activity in the biosynthesis of dihydrotestosterone.[44] Besides effects on mammalian physiology, Ganoderma lucidum is reported to have anti-bacterial and anti-viral activities.[51][52] Ganoderma lucidum is reported to exhibit direct anti-viral with the following viruses; HSV-1, HSV-2, influenza virus, vesicular stomatitis. Ganoderma lucidum mushrooms are reported to exhibit direct anti-microbial properties with the following organisms; Aspergillus niger, Bacillus cereus, Candida albicans, and Escherichia coli. Other benefits were studied such as the effect of lowering hypertension, cholesterol, and anti-inflammatory benefits through the ganoderic acid properties. Read more
