This article's final section opens with the sentence: "Numerous studies of lingzhi, mainly in China, Korea, Japan and the United States, has shown its effectiveness in the treatment of a very wide range of diseases and symptoms." Not one of those studies is cited, and I found no such studies in Google and no mentions of lingzhi (or reishi or ganoderma) on major medical sites. This section should either be sourced or excised. | Keithlaw 18:54, 15 November 2005 (UTC)

I have referenced those and other statements and removed the verification notice. Karen S Vaughan 18:07, 24 May 2007 (UTC)
Scientific studies typically use the scientific (sic) name, Ganoderma Lucidum, rather than the Romanized Japanese or Chinese names Reishi or Lingzhi. There are other closely related species in the Ganoderma family, and the scientific nomenclature is the only consistent and complete way to name and distinguish all of the known species. English does not have a word for Reishi, and Chinese does not have a word for the Oregon polypore. --Turpin (talk) 15:17, 12 May 2009 (UTC)
Modern scientific studies
Definately POV - the section takes an opportunity to defend 'traditional oriental wisdom' from Western conceptions of medicine. That sort of talk should be elsewhere. The bottom line is, many of the traditionally-ascribed properties have not yet been corroborated by science (which is not traditional oriental wisdom, but is the title of the section). I would, at minimum, excise a whole paragraph. 184.108.40.206 20:26, 4 February 2006 (UTC)
The first paragraph currently (May 11, 2009) reads as: Scientific studies of lingzhi, mainly in China, Korea, Japan and the United States, have been conducted to a limited extent, mostly in cell culture and rodents. The studies have not given any explanation of lingzhi's purported diverse effects, because none of the known active components taken alone have produced results comparable to the anecdotal reports surrounding intake of lingzhi itself, raising the question of whether synergy is important or if the testimonial evidence is faulty. For example, reports of lingzhi's effect on stamina, appetite, and other human conditions are largely anecdotal and haven't been studied scientifically. In the absence of scientific validation, lingzhi's "miraculous powers" are most credible from the traditional Chinese medicine point of view.
I Turpin have several issues with this first paragraph. The sentence fragment, "... to a limited extent, mostly in cell culture and rodents", is contradicted by other sources such as  where in vitro studies on human beings are discussed.
The sentence, "The studies have not given any explanation of lingzhi's purported diverse effects, because none of the known active components taken alone have produced results comparable to the anecdotal reports surrounding intake of lingzhi itself, raising the question of whether synergy is important or if the testimonial evidence is faulty," seems to imply that active components taken alone have been studied extensively, without providing any reference to such studies. As far as I know, there are far more in vitro studies on whole extract than on high-purity, one-component extract. Furthermore, lack of effectiveness of single-component formulas does not mean lack of explanation. Many of the compounds in Lingzhi are either known or believed to have specific phramacological properties, and although synergy of multiple compounds may be a significant factor, that is not the same as a lack of explanation.
The sentences, 'For example, reports of lingzhi's effect on stamina, appetite, and other human conditions are largely anecdotal and haven't been studied scientifically. In the absence of scientific validation, lingzhi's "miraculous powers" are most credible from the traditional Chinese medicine point of view,' are also problematic, because lack of verification resulting from lack of study is not the same as lack of credibility. The anti-allergic and diabetes resistance properties that have been verified are already one possible explanation, and no study has ruled out additional mechanisms for increased stamina. The fact that western science has concentrated on diease-fighting rather than wellness-supporting may have more to do with funding considerations by particular researchers than with credibility. Perhaps some sports medicine researchers ought to study Lingzhi, but lack of evidence is not evidence of absence. - Turpin
I Turpin am considering how best to revise this. Comments are appreciated. -Turpin
- The section in question indeed needs an overhaul. There's a lot of OR in there that needs to be removed or else verified with proper references. Bear in mind though that although several studies support positive effects of Lingzhi on human health, many of them have been published in rather obscure journals. Evidence-based studies published in journals with more exacting standards (eg, J Natural Products and other ACS journals) are beginning to emerge that report results from controlled experiments testing isolated Lingzhi compounds such as ganoderic acids and lucidenic acid, on human or other mammalian cell lines, which suggest some activity of these compounds against cancer or other malignancies. Despite this, we're still way off from a comprehensive overview of the effects of this fungus on human health, and it doesn't help that it has a lot of mystique attached to it that clouds rather than clarifies what its active principles are. I have the entry on my watch list, and will chip in/comment as needed. Malljaja (talk) 19:46, 11 May 2009 (UTC)
One of the problems was, even the sentence that is supported by a reference is outdated information. So I've modified the intro paragraph for modern scientific studies to give it more of a tentative rather than definitive reading. --Turpin (talk) 15:18, 12 May 2009 (UTC)
Is it better known in English as lingzhi or reishi? Badagnani 05:57, 6 August 2006 (UTC)
My question exactly! I thought this mushroom was better known as "reishi".220.127.116.11 07:01, 3 May 2007 (UTC)BeeCier
I think the general public knows it better as Reishi. In Chinese medicine it is better known as Ling zhi. It seems too much trouble to go through and change the references for consistency and to move it. They get redirected here all the same. Karen S Vaughan 18:09, 24 May 2007 (UTC)
It is known almost exclusively as "reishi" in English, and is labeled as such by sellers. The section on languages is misleading, because in English it is called "reishi" as a loan word from the Japanese. That fact is not mentioned.77Mike77 (talk) 12:25, 5 March 2014 (UTC)
I've moved this copyvio from the article to the talk. If anyone cares to include this information without copying wholesale, it is here for your ref. --Rifleman 82 10:05, 20 May 2007 (UTC)

(Quoted from http://www.reishirescue.com/index.cfm?Fuseaction=ArticleDisplay&ArticleID=360) Ganoderma has been recognized traditionally and scientifically as potentially useful in the treatment of cancer, but there is a notable discrepancy with the publics frequent impression that ganoderma may be a cure for cancer and the lack of clinical trials demonstrating such efficacy. We intend to summarize the extent of available theoretical, experimental and clinical data for the use of Ganoderma Supplementation in cancer and outline its indications, especially in the context of clinical results from bioactively similar polysaccharide derived biological response modifiers (BRMs) from other fungi (Mizuno 1996). Experimental Evidence of Ganodermas Potential in Cancer Treatment Ikekawa et al. (1968) first reported on the efficacy of soluble extracts from Ganoderma in inhibiting transplanted sarcoma 180 in mice. This host-dependent anti-tumor activity has been subsequently confirmed to be from the polysaccharide fractions of Ganoderma (Sasaki et al., 1971). Multiple similar studies subsequently confirms this observation and anti-tumor efficacy of Ganoderma has been demonstrated from various species, at different stages of growth and using different solvents for extraction and different routes of administration. Anti-tumor activity has been demonstrated in vitro as well as in syngeneic tumor systems in animals. However, no human trials of Ganoderma against cancer in peer reviewed journals nor any controlled clinical trials in humans have yet been conducted or published.
From a theoretical point of view, it is important to note that other fungal polysaccharides of comparable structure and function as those found in Ganoderma have undergone rigorous clinical trials, including Lentinan, Sizofilan, PSK (Krestin), PSP. Since it is now increasingly clear that immunostimulatory bioactivity from most beta-glucan based compounds function via a similar beta-glucan receptor (Czop 1985), it has been possible to hypothesize that Ganoderma polysaccharides should function similarly (Chang, 1996). Clinical effects of various glucan based BRMs should therefore be comparable. Results from Lentinan, Sizofilan, PSK and PSP human trials demonstrated the efficacy of these glucan BRMs in prolonging survival in recurrent or advanced gastric and colon cancer, lung cancer and gynecological cancers, Data from such bioactively comparable compounds all suggest improved quality of life or survival for cancer patients may be possible with Ganoderma supplementation.
Indications and Evidence Supporting the Use of Ganoderma Supplementation in Cancer
Whilst some efficacy of Ganoderma in cancer is undoubted, it remains important to specify the various indications and cite the evidence to support its use. This can be discussed under four different circumstances:
A. As a supplement during chemotherapy or radiotherapy to reduce side-effects such as fatigue, loss of appetite, hair loss, bone marrow suppression and risk of infection. There are studies demonstrating Ganodermas efficacy against fatigue (Yang 1994), hair loss (Miyamoto et al. 1985), and bone marrow suppression (Jia et al. 1993) and the presence of similar clinical evidence for other glucan BRMs applied in the setting of cancer chemotherapy or radiotherapy (Shi 1993) lends further support to the supplementation of Ganoderma in combination with cytotoxic cancer therapies. The recommended dose should be in the range of five to ten grams of fruiting body or equivalent per day (Chang 1994).
B. As a supplement for cancer patients to enhance survival and reduce likelihood of metastasis. While only anecdotal data exists that ganoderma supplementation may enhance survival of cancer patients, this survival advantage has been demonstrated for a number of comparable glucan BRMs. Specifically, Lentinan use in advanced or recurrent gastric cancer demonstrated a significant life span prolongation advantage at 1, 2, 3 and 4 years in a randomized control trial (Taguchi 1987). Sizolan given together with chemotherapy enhanced survival of cervical cancers irrespective of stage in a prospective randomized controlled trial (Inoue et al. 1993), significantly enhanced survival (P.01) in lung cancer patients (Honma 1982) and improved five year survival of head and neck cancer from 73.4 to 86.7% was noted in another small study (Kimura et al. 1994). More appropriate for comparison to Ganoderma is perhaps PSK or PSP, which are orally administered. Mitomi et al. (1994) found significantly improved survival and disease-free survival (P=0.013) in resected colorectal cancer given PSK supplementation over three years when compared to control in a multi-center randomized controlled trial.
In an animal model, Ganoderma has been demonstrated to effectively prevent metastasis (Lee 1984), and these results are comparable to those of Lentinan (Suga 1994). Other glucan BRMs have been demonstrated to effectively prevent or suppress pulmonary metastasis of methylcholanthrene-induced sarcomas, human prostate cancer DU145M, and lymphatic metastasis of mouse leukemia P388 (Kobayashi et al. 1995). The recommended dose should be five to ten grams or more of fruiting body or equivalent per day, with a linear enhancement in efficacy expected up to 30 grams per day (Chang 1994).
C. As a supplement for cancer patients to improve quality of life. Again, only anecdotal information exists for Ganoderma in this situation but other oral glucan derivatives such as PSP has been found to be useful in improving quality of life in cancer patients (Yao 1993). Significantly, Ganoderma supplementation was noted to decrease pain in cancer patients (Kupin 1994). The recommended dose would be five to ten grams of fruiting body or equivalent per day (Chang 1994).
D. As a supplement for the prevention of occurrence or recurrence of cancer. Since immune stimulation, especially Natural Killer (NK) and Cytotoxic Lymphocyte (CTL) activation may be effective in the immune prevention of cancer by enhanced immune surveillance (Lotzova 1985), and Ganoderma has been demonstrated to enhance NK and CTL activity when administered orally (Won et al. 1989), it is thus a candidate for prevention of the occurrence or recurrence of cancer. Stavinoha et al. demonstrated the efficacy of Ganoderma in preventing the progression of microadenomatous growths in animals (Stavinoha 1993), and the efficacy of other glucan BRMs in primary and secondary cancer prevention have been similarly demonstrated in vitro, in vivo and in clinical trials.
Although Ganoderma and its derivatives are not pharmaceuticals and have not undergone rigorous clinical trials to be tested against cancer, there is abundant use in vitro, animal and indirect clinical evidence to support its supplemental use in cancer. Standardization in bioactive polysaccharide content and dosages will be necessary to assure its rational use, and clinical trials in select cancers with defined endpoints will confirm its efficacy.
Material from the Ganoderma article
The article on Ganoderma was all about Lingzhi, even though Ganoderma is a genus with multiple species.
Some of the information is not in this article, so I am pasting it here so it will not be lost. Feel free to take this text and put it into this article where appropriate.
For over 2000 years, Reishi Mushrooms (Ganoderma lucidum) have been considered by the Chinese to be a high quality herbal medicine. In the traditional Chinese medical theory, Reishi or Lingzhi is among the highest ranking. It can improve overall health, increase the body's healing ability, promote longevity and it does not bring along any side effects even taken a long period of time. According to Dr. ShiJean Lee, the most famous Chinese Medical Doctor of the Ming Dynasty, long term consumption of Reishi will build a strong, healthy body and assure a long life. Modern medical research also proves that Reishi has a wide range of medical effects.
Its main function is to promote blood circulation and increase the metabolic activities of cells (detoxification) and also help the proper functioning of all internal organs (balance the body functions).
Lingzhi can be taken daily, for long periods, with out any adverse side effects. Long term use of lingzhi can help normalize body function and empower the immune system to fight disease. It is not merely a medicinal mushroom that heals a particular disease, but is considered to be an adaptogen, that is it helps to regulate and mobilize all bodily functions.
To achieve the highest ranking, a herbal medicine must satisfy the following conditions: It should be non toxic( have no side effects), Its effects should not be limited to a specific part, or organ of the body, - It should be able to normalize all of the body's functions.
4 Basic Principles in Ganotherapy
- Illness is caused by 2 sources; toxins in our body and disharmony in body functions.
- Ganoderma does not cure illness but it can help balance up our body system and improve immunity against diseases.
- Any reaction that takes place is caused by our body system and not by the intake of Ganoderma.
- The Dosage of Ganoderma taken is irrelevant to diseases.
The Power of Reishi
RG ( Reishi Gano ) is a kind of mushroom essence ( Ganoderma lucidum ) widely known as "King of Herbs". It contains more than 300 active elements which can be divided into three categories including 30% of water-soluble elements, 65% of organic-soluble elements, and 5% of volatile elements. The main active elements are: Polysaccharides, Organic germanium, Adenosine, Ganoderic essence, Triterpenoids, Protein, and Fibre.
Strength of GL :
- Strengthens body resistance
- Cleanses toxins out of the body
- Provides full range of vitamins and minerals
- Helps to maintain a healthy gastric and renal system
Important Elements found in Reishi
Through modern scientific analysis, there are more than 200 active elements found in Reishi. The main active elements are :
Polysaccharides stimulate or modulate the immune system by activating the immune cells such as macrophage and helper Tcells as well as increase the levels of immunoglobulin (antibodies) in fighting the unwanted foreign cells such as bacteria, viruses etc. It helps to cleanse toxic deposits from body, strengthen the natural healing ability of the body, convert abnormal cells into normal cells, strengthening the resistance of the body and thus improve overall health. Experiments at the Drug Research Institute in Toyama, Japan :confirmed that polysaccharides in reishi are responsible for the immune enhancement. In Japan, Reishi extract has been reported to be effective in treating patients with liver failure.
Triterpenoids are responsible for Reishi's bitter taste and several of its medicinal properties. It is the component, which responsible in improving blood pressure and blood lipid. Triterpenoids have a kind of harmonizing effect on the body especially on the immune system as well as the circulatory system. It gives Reishi an adaptogenic quality, providing the person with protection. from a wide range of biological, environmental and social stresses.
Adenosine improves blood circulation by inhibiting blood platelet aggregation. An earlier study done by a team of researcher from Beijing College of Traditional Chinese Medicine found that Reishi improves the function of red blood cells in transferring oxygen. They related this result to the adenosine in Reishi. Adenosine is also helpful in lowering the cholesterol level and regulating the metabolism and hence promoting vigour and vitality.
The content of organic germanium in reishi is very high compared to any other herb in the world. The following are some of the functions of organic germanium in our body.
- Increases oxygen supply to the blood stream
- Revives cell tissues by increasing oxygen supply to body organs.
- Increases body's metabolic rate.
- Eliminates electric energy around abnormal cells and turn abnormal cells in to normal cells.
- Relieves fatigue.
Ganoderic essence is a rare ingredient found in herbs. This is the element which gives reishi the shining property. Ganoderic essence can beautify the skin and it is helpful in treating skin related diseases. Because of Ganoderic essence, reishi can be used externally for skin related problems and for small cuts and wounds. Studies conducted by various researchers reveal that, continuous usage of Ganoderic essence can retard ageing.
In today's world, large proportion of the population is constantly in the state of 'preillness' due to environmental pollution, stresses and unhealthy lifestyle such as consuming diet which is high in fats, cholesterol, sugar, salt and with the abundant supply of frozen and processed foods compounded by chemical additives. Under these circumstances, it is wise to prevent any deterioration in health rather than seek a cure after illness prevails. As recorded in the oldest Chinese medical text, Reishi is to be used for preventive measures rather than a cure. Therefore, Reishi is the best solution for modern day sickness because it is the nature's best gift for mankind.

Independent Reishi Research link The following link: Independent Research Database on Reishi Medicinal Properties (http://www.vermontmushrooms.com/herbmed_gmm.php?HerbID=3) is hosted by my company (Green Mountain Mycosystems, LLC), and the research database is created and maintained by HerbMed which is a non-profit dedicated to providing independent scientific information on traditional herbs which offers memberships for a modest fee to cover the costs of maintaining the database. In the case of Reishi, Maitake, Shiitake, and Cordyceps, my business leases this information from them (dynamically provided from their site to ours every time a person is viewing a database entry) to make it publicly available for free instead of having people need to purchase a membership to view this important information. The link to this databased historically in the ling zhi article goes straight to the database, which complements the ling zhi entry and provides up to date research on reishi which is entirely independent from the financial interests of my business. I started my business out of my passion for medicinal mushrooms and fail to understand how a link to a free database on reishi's medicinal properties can be considered spam simply because a known spammer complained about another business having a link (who I will not mention, but you can look at the history to know who I refer to if you want to). Any feedback on reasons for or against removal of this link would be greatly appreciated. Thank you, David Demarest ReishiDave —The preceding unsigned comment was added by Reishidave (talk • contribs) 07:05:31, August 19, 2007 (UTC).
- I can see your point. However, there's obviously some complexity to this issue that will likely get missed, as not all readers and contributors read the talk page. So it is very likely that inclusion of your link will lead again to notions of "if this link is in there, mine might very well be in there too", placing the onus on admins and other contributors to sort out what is commercial spam and what is not. Ideally the information given in the HerbMed database should filter through into the wiki entry--as you have access to this information, I can see one possible solution in that you include to the article any new info as it becomes available. This may seem arduous, but it's in fact easier to do with a curated database to which you have access than trying to gather info from many different sources, as most other contributors have to do. While I see the value of having direct access to a Lingzhi database, the linking via your commercial enterprise in my opinion precludes inclusion of your link. Malljaja 09:24, 19 August 2007 (UTC)
I am happy to add upon the wiki entry applicable information on reishi and definitely do so as my schedule allows; however the sheer volume of research available in the database would create an very long winded reishi entry or a relative lack of organized scientific research in my opinion. I can't help but think that items 3 and 4 of "Links Normally to be Avoided"(http://en.wikipedia.org/wiki/WP:EL#Restrictions_on_linking) are the only applicable reasons to delete the Independent Reishi Database link but that they do not preclude a commercial business being linked to if the link is actually providing useful independent information instead of primarily attempting to promote or sell products. Just my additional 2 cents, David Demarest ReishiDave —The preceding unsigned comment was added by Reishidave (talk • contribs) 00:18, August 20, 2007 (UTC).
- Move to Reishi. More commonly used English name for this plant. Badagnani (talk) 20:44, 9 December 2007 (UTC)
I have moved this side effect paragraph to the discussion because it has no citation, and because I corrected it with citations earlier but my edits were deleted.
It has been shown in some studies that long term use of lingzhi can result in some mild side effects, including dryness of the nasal passages, mouth and throat, as well as stomach upset and nosebleed.
I have moved a portion from the section on Preparation to the paragraph below for dicussion on its merits. It lacks citations to support it, and its main motive seems to be to disparage scientific studies and non-traditional, modern, Western, or mass-production preparation methods regardless of whether or not they have medicinal effects simply because they are non-traditional. The explanation of what the traditional preparation method are also needs more citation, however I am leaving it in the article because it serves to inform rather than to bias.
Because mushrooms contain chitin which locks up medicinal components, preparations of lingzhi are unlikely to be medicinally active, unless there has been a prolonged hot water extraction.  Simply tincturing the mushroom in ethanol or powdering it and encapsulating it makes preparations that are essentially inert and may account for some of the inconsistency in research results. Additionally, mushrooms traditionally incorporate or transform constituents from their host trees and mycelial fractions grown in sawdust or other substrate may differ appreciably from the whole fungus.
Structure, wording, and references
I've just taken out the entire section Modern scientific studies and incorporated some usable bits into Scientific studies and therapeutic usage. There were several issues with the MSS section: one, it was a raw mush of factual or fictious content in prose that had little coherence or logical direction; second, much of the info was already given in the preceding sections; and third, few if any references were provided. I've also removed the numbered citations at the bottom of the page, because they are useless in a dynamically changing editing environment. I apologise if I deleted any references of value, but at least part of the blame has to be placed onto those who've ignored the guidelines for citing sources. Malljaja (talk) 19:36, 10 July 2009 (UTC)
References and research
I agree with Malljaja, this section of the article can be improved. However, deleting interesting research (like Reishi enzyme kinetics experiments) and calling them "pointless", is not the way to do it. Jatlas (talk) 04:59, 28 August 2009 (UTC)
- This figure is pointless, simply because it doesn't provide meaningful information. It is entirely unclear what the activity of this enzyme does (even in the original entry), and why, therefore, it is a good thing that Ganoderma depresses its activity. Also, there's a reduction by ~50%—what does this mean? Fifty percent of what, and is this decrease biological significant? Have these findings been replicated in other studies and what were the controls the authors used? This is very primary research data without any context, so this does not really belong here. The same goes for the large number of studies given in the in-line citations, which seem merely aimed at a WOW! effect, until closer inspection reveals that most of them have been published in obscure journals, mainly using in animal models, or in vitro. This article needs a serious overhaul, because Ganoderma is an interesting group of fungi that make an interesting variety of compounds. I've started on this by developing a prose for the major findings to makes this entry more conform with WP:MoS. More is to come. Malljaja (talk) 13:45, 28 August 2009 (UTC)
I agree with you Malljaja, well said. I would like to expand some of this research in the current form (not going back to bullet points). The research you have outlined and summarized looks good, although it has been skimmed down to the essentials. In regards to the enzyme research, I believe this deserves to be mentioned, although it should be presented differently this time. Research with 5-alpha-reductase (which synthesizes dihydrotestosterone) is analogous to research you posted already like information about the inhibition of the enzyme "lanosterol 14α-demethylase" (with synthesizes cholesterol). Looking forward to working on this article with you. Jatlas (talk) 15:11, 28 August 2009 (UTC)
- That sounds good to me—I fully agree that the research section deserves some expansion and also some critical evaluation. The recent review by Paterson (cited in the entry) may be one source that could be helpful, as it discusses some of the shortcomings of the empirical and anecdotal research that has a dominated the Ganoderma literature vs the relatively new development of evidence-based studies on these species. We can kick around some ideas on how to incorporate this. By the way, I very much like the gallery pictures you have added. Thanks. Malljaja (talk) 15:51, 28 August 2009 (UTC)
Citation on frequency of growth?
Reishi spores posses same beneficial properties of the mushroom and are way more concentrated?
The spores of the mushroom are sixty times more potent still, but the cell walls of the spores must be "cracked" before they are bioavailable to us. Once cracked though, the spore will deteriorate, and the common practice is to combine them into oil for preservation. Dragon Herbs has an awesome cracked reishi spore oil. Cracked reishi spores will be almost impossible to find, so one should jump at the chance to take some if available, especially if one is dealing with an immune deficiency issue.
