Chinese: Ling Zhi

Japanese: Reishi

About Reishi

Reishi (Glossy Ganoderma, Ganoderma lucidum, Ling zhi) is a non-poisonous but inedible wood-decay fungus. It is inedible only due to its hard consistency and relatively bitter and pungent taste. Reishi grows mainly on damaged trees or stumps. It draws nutrients from the wood. Its Czech name is derived from its appearance. The cap is reddish-brown to dark brown and very shiny, giving the impression that it is varnished; it is sessile and semicircular.

Reishi originates from Asia, but today it can be found all over the world, partly because it is artificially cultivated, as it no longer occurs much in the wild and the demand for it is enormous. During artificial cultivation, it is also possible to slightly change the composition of the mushroom according to the substrate on which it is grown; moreover, it is possible to harvest mycelium or fruiting bodies of different ages. Each developmental phase has a slightly different composition of active substances. Reishi grown on oak trunks and harvested after 6-9 months has an optimal composition.

If we wanted to look into history to see when Reishi began to be cultivated, we would have to go very deep. Reishi has been known for about 2000 years and is described in many Chinese herbals, including the most famous one, Shen Nong Ben Cao Jing, which dates back to before our era, i.e., 206 BC. Even then, Reishi was highly valued; it was attributed with life-prolonging and strength-giving effects, and it was even stated that it brings the dead back to life. It is no wonder that it has the nickname the mushroom/elixir of immortality. The popularity of Reishi in ancient China was enormous, and so it also began to be cultivated.

It was different in the so-called Western world. The mushroom was not described until 1781 by the biologist William Curtis. For a long time, Reishi was not given attention, but reports of its effectiveness originating from traditional Chinese medicine prompted scientists to research it. Now we know the composition of Reishi, and some of its effects are verified by studies, including clinical ones with volunteers.

Characteristics according to traditional Chinese medicine

Si Qi (nature): neutral

Wu Wei (taste): sweet and slightly bitter

Gui Jing (tropism): heart, liver, lungs (according to some sources, it also has tropism to the kidneys)

Main effects according to traditional Chinese medicine

  • replenishes Qi and nourishes blood/yin
  • calms the Shen spirit
  • transforms phlegm and stops coughing
  • relieves shortness of breath
  • strengthens kidney essence

Effects according to traditional Chinese medicine in more detail:

1, Fatigue states

  • along with Cordyceps, it is probably the most used mushroom for fatigue states
  • it is used for both mental and physical fatigue
  • it is typically used for states that traditional Chinese medicine calls Qi energy deficiency
  • it helps with the restoration of strength during or after long-term illnesses, but also, for example, before and after surgeries
  • Reishi is a 2-in-1. It can simultaneously replenish Qi and blood, which according to Chinese medicine are two basic substances of our organism. It is the fuel thanks to which we can function.
  • this is used for various states, typically for imbalances after childbirth, during the weakening of the organism during chronic illnesses, for anaemia, etc.

2, Strengthens kidney essence Jing

  • it can strengthen Jing essence, however, Cordyceps is significantly stronger in this effect

4, Strengthens Wei Qi

5, Supports Zheng Qi

  • Zheng Qi could be translated as our vitality or our life force
  • we are healthy if we are full of Zheng Qi, then Xie Qi will not penetrate us
  • Reishi is probably the best vital mushroom for supporting Zheng Qi

6, Adaptogenic effect

  • Reishi is an excellent adaptogen. It supports the functions of the organism to adapt to changing external conditions. This effect is also used as support during stress loads.

7, Allergies

  • Reishi is excellent for various allergic problems
  • it helps with histamine-mediated allergic reactions, which does not have to be just hay fever, but perhaps also reactions to various foods
  • triterpenes contained in Reishi participate in this reaction
  • Reishi does not act purely on acute allergic states (for example, in states of sneezing and runny nose as reactions to pollen), but is rather for long-term preventive use. For hay fever, I recommend using Reishi at least three months before the start of the pollen season.
  • for year-round allergic rhinitis, it is possible to use Reishi long-term throughout the year
  • if we use Reishi to alleviate allergic reactions, it is good to increase vitamin C intake very significantly
  • if I use Reishi before the pollen season, I sometimes combine it with the Agaricus mushroom
  • for food allergies, I often combine Reishi with the Enoki mushroom or with the Hericium mushroom

8, Asthma

  • Reishi has tropism to the lungs and can strengthen their functions
  • it is therefore used for asthma, COPD, pulmonary emphysema, etc.
  • for asthma, it is often combined with the Cordyceps mushroom, or possibly the Coriolus mushroom
  • for asthma, the effects of Reishi, such as supporting lung Qi and the ability to transform phlegm, complement each other beautifully

9, Cough

  • Reishi strengthens lung Qi, and therefore it is suitable for coughs from lung weakness. It is therefore mainly about chronic coughs.

10, Eczemas

  • Reishi is excellent for atopic eczema, especially in children
  • it is often combined with the Agaricus mushroom in these cases
  • if the eczema is weeping, the Polyporus mushroom is added

11, Cancer

  • Reishi is used for its anti-tumour action as complementary treatment for oncological states
  • Reishi supports the production of NK cells. These are responsible for "cleaning" the organism by liquidating cancer cells.
  • Reishi supports the formation of white blood cells that have an anti-tumour effect
  • in most cases, it is combined with other vital mushrooms, most often with Coriolus. A typical combination, for example for breast cancer, is Reishi + Coriolus + Maitake.
  • Reishi supports a person's vitality so that they can better handle conventional treatment such as chemotherapy or radiotherapy. With its properties, Reishi can reduce the negative impact of conventional treatment on the human organism.
  • it is recommended to use Reishi just like other mushrooms throughout the entire duration of conventional treatment plus another 2 months after it. After recovery, it is recommended to do one to two-month cures 1-2 times a year using Reishi in combination with other vital mushrooms.
  • Reishi is often used for tumours with the Coriolus mushroom. Both have anti-tumour effects. However, Reishi is more vitalising, whereas Coriolus is a bigger "killer" of cancer cells.

12, Menopause

  • Thanks to its ability to nourish Yin and liver blood and simultaneously harmonise the psyche, Reishi is used for menopausal problems, such as hot flushes and sweating or mental imbalances
  • it is mostly used in combination with Cordyceps. Cordyceps is then administered in the morning and Reishi in the evening. This combination balances Yin and Yang in the organism, in other words, it balances hormonal imbalances.

13, Hair loss

  • thanks to the ability to nourish liver blood, Reishi is used for problems with hair loss
  • it is used not only for hair loss, but also improves their quality if they are dry, dull, or split
  • according to the same mechanism, Reishi also strengthens the quality of nails

14, Nutrition of tendons and ligaments

  • traditionally, Reishi is also used to strengthen and nourish tendons, ligaments, joints, and bones, which is related to its nourishing function and influence on the kidneys and liver

15,

16, Autoimmune problems

  • Reishi can suppress the immune system if it reacts disproportionately to its own healthy cells
  • these problems are called autoimmune reactions and include: rheumatoid arthritis, lupus, autoimmune thyroiditis, type I diabetes, Sjögren's syndrome, etc. Reishi can be used for all these problems.

17, Supports the cardiovascular system

  • thanks to its tropism to the heart, Reishi supports the functions of the cardiovascular system and the heart itself
  • it is used for states of heart weakness, arrhythmias, tendencies to thrombosis, etc.
  • it is also suitable after a heart attack or stroke
  • Reishi has mild anticoagulant effects, so it is used as prevention against coronary diseases
  • in these cases, Reishi is often combined with the Auricularia mushroom. However, one must be careful because Auricularia must not be used concurrently with blood-thinning medication.

18, Harmonises cholesterol

  • Reishi can harmonise the level of cholesterol in the blood

19, Harmonises blood pressure

  • thanks to the ability to nourish the liver, Reishi can harmonise blood pressure
  • in these cases, there is no need to worry that Reishi would lower pressure too much and tip it into low pressure

20, Hyperthyroidism

  • Reishi helps with hyperthyroidism

21, Insomnia

  • sleep problems are, according to traditional Chinese medicine, most often associated with a deficiency of heart and liver blood
  • thanks to its ability to nourish liver and heart blood and its An Shen effect (the ability to harmonise the psyche), Reishi works excellently for insomnia states

22, Mental imbalances

  • Reishi nourishes heart blood, and the Shen spirit, which is responsible for our psyche, our emotions, thinking, etc., resides in the heart.
  • Reishi has an AnShen effect, so it calms and harmonises the Shen spirit
  • for this reason, Reishi is used for states such as insomnia, then various mental imbalances, mental instability, mental restlessness, easy excitability, depression, anxiety, etc.
  • with long-term use, Reishi increases resistance to emotional stress
  • it also supports memory and mental functions, the ability to concentrate, the ability to learn – in these cases, it is combined with the Hericium mushroom
  • Reishi also helps with palpitations, arrhythmias, especially if they are dependent on emotions
  • Taoist monks used Reishi before meditation because it improved their concentration and ability for mental harmonisation

23, Neuro problems

  • in combination with the Hericium mushroom, Reishi is administered for states such as Parkinson's disease, Alzheimer's disease, senile dementia, multiple sclerosis, or neuropathy

24, Athletes

  • Reishi improves the absorption of oxygen by tissues, which athletes use in both the preparatory and performance phases
  • Reishi supports strength and performance and shortens the regeneration phase

25, Protects the liver

  • just like most other vital mushrooms, Reishi can protect and regenerate liver cells
  • it is therefore used for chronic hepatitis – triterpenes contained in Reishi contribute a lot to this effect
  • Reishi also helps to regenerate the liver if it is burdened by excessive alcohol consumption or, for example, long-term use of Western medication

26, Diabetes

  • Reishi can regulate and stabilise blood sugar, improves the responsiveness of tissues to insulin, it is therefore suitable for type II diabetes, where I often combine it with the Maitake mushroom and/or Coprinus

27, Anti-ageing effects

  • Reishi is called the mushroom of immortality
  • mainly because of its ability to replenish kidney essence, it is used to slow down ageing

28, Support of organism detoxification

  • Reishi strengthens the kidneys and liver and supports them so that they get rid of various substances undesirable for our organism better, various toxins, metabolites, it can remove heavy metals from the body (vaccination), etc.

Less frequent use of Reishi:

  • protection against radiation
  • DNA
  • regulates blood fats
  • antioxidant effects
  • anorexia
  • neurasthenia
  • overweight
  • arthrosis

Dosage:

  • mushrooms can be used in various forms. Most often, the form of hot-water extracts with 30% polysaccharides is used for health problems.
  • just like with other mushrooms, I recommend using them for 5 days and taking a 2-day break, especially if solving problems related to the immune system (even secondarily, i.e., I use this rule almost always)
  • you can learn more about using vital mushrooms here

a, Mushrooms in the form of extracts (recommended form of use)

If you use mushrooms in the form of 30% extracts, I recommend:

Preventive use

  • 1 g of mushroom extract per day (of all mushrooms combined)

For milder health problems

  • 2 g of mushroom extract per day (of all mushrooms combined)

For more serious health problems

  • 3-5 g of mushroom extract per day (of all mushrooms combined)

b, Mushrooms in tincture

  • dose the tincture according to weight
  • usually, as many drops are given as a person weighs
  • this daily dose is divided in half, half is used in the morning and half at noon

c, Mushrooms in the form of powder (biomass)

  • usually 2-3 times a day a teaspoon of mushroom powder mixed in water
  • this is more for preventive use

d, Dried mushrooms

  • 20-100 g per day
  • either they are added to food, or decoctions are made from them
  • you prepare a decoction by taking 100 g of mushrooms and putting them into about half a litre of cold water and boiling for half an hour on a low flame. Some mushrooms can be eaten even with the decoction (e.g., Hericium), some are too woody to eat (like Reishi).

Contraindications and known drug interactions:

  • it is probably the only one of the mushrooms that I commonly give during pregnancy

Pharmacological effect:

  • anti-tumour action
  • anti-diabetic effects / reduction of glycaemia
  • reduction of fats
  • prevention of cardiovascular diseases
  • protection and regeneration of the liver
  • protection of the nervous system
  • improvement of mood
  • strengthening of physical condition
  • against osteoporosis
  • against pain and for healing

What we find in Reishi

Like every mushroom, Reishi is also made mainly of water, i.e., up to 90%. The remaining part, the dry matter, is however packed with bioactive substances that have a positive influence on the organism. We will mention the most significant components in the following text.

1, Terpene compounds:

With other mushrooms, we started with polysaccharides, but with Reishi, we will start with terpene compounds. They are exactly what give Reishi its bitterness and pungency and also many effects for which it excels.

Terpenes have the ability to destroy tumour cells and oxidative stress and blood fat values.

More than 50 triterpenes have been successfully extracted from Reishi, among which belong

  • Ganoderic acids
  • Ganoderols
  • Ganoderales
  • Ganoderiols
  • Ganoderones
  • Lucidumols
  • Ganodumones A–F
  • Ganodermaones A and B

Given the significance of ganoderic acids, we will look at them more closely. There is a whole spectrum, it is possible to say from A to Y, then DM and C2. Ganoderic acids are significant for their anti-tumour effects. They can stop the cell cycle, thanks to which cells multiply, and induce cellular death, apoptosis, in them. However, they also limit metastatic activity, mainly by reducing the production of enzymes that break down intercellular matter. If the intercellular matter is loosened, the tumour cell passes through it better and gets outside the place of its origin, i.e., it metastasises. Under the influence of ganoderic acids, the expression of metalloproteinases is reduced.

Effects have been proven, for example, on cells of lung, colon, liver, prostate, bone, cervical cancer, etc. An important component of the anti-tumour effect of ganoderic acids is also the fact that they cancel the resistance of tumour cells to treatment. Many tumour cells do not respond to chemotherapy at all, but ganoderic acid makes them sensitive and strengthens the effects of treatment.

It is not possible to omit their antioxidant properties, i.e., they reduce oxidative stress, which stands behind many degenerative diseases, including dementias, tumours, etc. Thanks to the neutralisation of free radicals, ganoderic acids act protectively against organ damage.

2, Carbohydrates

The dry matter of Reishi is largely made up of carbohydrates. The most important are undoubtedly polysaccharides (more than 200 types have been successfully obtained from Reishi), among which also belong glucans. In Reishi, there are beta-1-3 and beta-1-6-D glucans. We cannot omit other polysaccharides, namely ganoderans A, B, and C. Other polysaccharides are also those insoluble and unabsorbable, i.e., fibre, which is food for intestinal symbiotic bacteria.

Besides polysaccharides, there are also monosaccharides in Reishi, mainly mannose, ribose, glucose, galactose, fucose, and arabinose.

3, Fatty acids/fats

Fatty acids are an integral part of Reishi. It is important that they are mainly unsaturated ones in it, which are beneficial to health. These are mainly oleic and linoleic acid. Saturated fatty acids, namely palmitic and stearic, are also present in Reishi in smaller amounts.

4, Amino acids, peptides, proteins

Mushrooms, therefore also Reishi, are unique in that they also contain amino acids and proteins. All amino acids are represented in Reishi, i.e., non-essential, which our organism can create, and essential, which the body does not have to produce and it is necessary to receive them in food.

Among proteins, many enzymes are worth mentioning. These are mainly enzymes that can break down wood matter so that the mushroom can obtain nutrients from it, e.g., galactosidases, ligninolytic oxidoreductases...

An important protein is Ling Zhi8.

Just as we highlighted ganoderic acids, we will also devote ourselves to the Ling zhi 8 protein, which can be obtained both from the mature mushroom and from mycelia. It was described in 1989. In its structure, it is in many ways similar to the heavy chain of human antibodies, immunoglobulins. It is composed of amino acids aspartic acid, threonine, serine, glutamic acid, glycine, alanine, cysteine, valine, and methionine. Scientists were interested in its composition, and therefore many studies were conducted.

These were, for example, tests on animals with anaphylaxis, i.e., an allergic reaction, which can lead to the death of the affected person. In sensitised mice (an antigen was administered to them beforehand so that an allergy would be created to it), to which an allergen was administered, a serious reaction occurred within 30 minutes, respiratory frequency decreased, cramps and also death occurred. However, if sensitised mice, which were exposed to an allergen dangerous to them, also received Ling zhi 8, the situation was different. No serious anaphylaxis occurred that would endanger the animals' lives. Administering Ling zhi to allergic mice before exposure to the allergen therefore led to limiting the development of the allergic reaction.

Subsequent studies then brought further evidence about the effects of Ling zhi 8.

Anti-cancer effects were also proven. In its presence, the multiplication of lung cancer cells was limited, as it blocks the cell cycle that a cell must pass through in order to be able to divide and give rise to a new cell.

5, Nucleosides and nucleotides

Compounds that are part of genetic information, i.e., DNA and RNA, are also found in Reishi. These are, for example, adenine, adenosine, uracil, uridine... Nucleosides are also used in medicine, mainly adenosine, it can adjust heart action, i.e., it is against arrhythmias, and lowers blood pressure. It can also reduce the clumping of blood platelets, i.e., it acts antithrombotically, against the formation of blood clots.

6, Sterols:

Sterols are substances that are built on a steroid nucleus, like cholesterol. Ergosterol, i.e., provitamin D2, occurs in Reishi. In the body, it acts identically to vitamin D from animal sources.

7, Phenolic compounds

We cannot end the list of Reishi components without mentioning phenolic compounds, among which also belong flavonoids. These are substances with significant antioxidant effects. To this group belong, for example,

phenols

  • Chlorogenic acid
  • Cinnamic acid
  • p-Coumaric acid
  • Gallic acid

flavonoids

  • Quercetin
  • Rutin
  • Myricetin
  • Morin

8, Minerals and trace elements

Reishi also contains many minerals and trace elements that are essential for our health. These are mainly sodium, potassium, zinc, selenium, iron, copper, magnesium, etc. The amount and type of these elements differ according to the place where the mushrooms grow, as they accumulate minerals from the environment.

9, Vitamins:

It probably won't surprise you that there are also vitamins in Reishi. And mainly B-group vitamins and the already mentioned vitamin D.

10, Other substances:

Although Reishi has been researched for many years, other significant components are still being found in it. Interesting are, for example, lucidolactones A and B.

Alkaloids lucidimines A to D, we will talk a little more about lucidimine B and C.

Lucidimines from Reishi have significant antioxidant potential. They reduce "toxic" oxidative stress, which accelerates the degeneration of the organism, increases the risk of cancer, etc. Scientists tested them in solutions, where they dealt very well, for example, with peroxyl radicals. Overall, lucidimines in antioxidant effects are on par with vitamin C.

Besides antioxidant effects, anti-tumour effects were also successfully proven. Experiments were conducted on cell cultures of breast cancer. Lucidimines had an antiproliferative effect, tumour cells stopped multiplying in their presence. These alkaloids stop the cell cycle that a cell must reach in order to be able to divide and thus give rise to a new cell. Also important is the fact that lucidimines can start intracellular signalling pathways that lead to apoptosis, i.e., cellular death. This is also triggered by the fact that lucidimines damage mitochondria, which produce energy essential for cellular life.

Effects of Reishi according to studies

We have already discussed the most fundamental components from Reishi, thanks to which we also touched upon some effects of Reishi. Now we will look at some more closely and state some studies, including clinical ones, if they are available.

Research is most often conducted on cell cultures; it is the "easiest" from the point of view of ethical rules. Studies with volunteers are the hardest to conduct; firstly, there are very strict rules for including people in studies, and secondly, these studies are very expensive.

A71. Front Immunol. 2020 Sep 29;11:561758. doi: 10.3389/fimmu.2020.561758.

Reishi, the scourge of cancer cells

Tumour diseases are increasingly common in the population. This is due to lifestyle, environmental pollution, and the fact that we are living to an older age. Thanks to early diagnosis and effective treatment, many people with cancer survive, yet many people succumb to cancer. Even the treatment itself is very demanding and health-damaging. Scientists are trying to find treatment that would be sufficiently effective but at the same time non-damaging.

It turns out that Reishi contains substances that have anti-tumour effects, as we have already stated above in the composition. Experiments on cell lines of various types of cancer proceed by adding Reishi to the cell culture in which cells multiply and observing the reaction of the cells to the presence of Reishi. Cells of many types of cancer (breast, lung, colon, meninges, sarcoma, liver, cervix, leukaemia) stop multiplying in the presence of Reishi, cell division is stopped, so the tumour would not grow. Moreover, a large part of the cells undergo apoptosis, i.e., cellular death. Reishi kills tumour cells. Moreover, it limits the new formation of blood vessels that would supply the tumour with blood, and therefore also with nutrients and oxygen. We must also mention that Reishi deprives tumour cells of the ability to move, therefore also to travel out of the tumour and create metastases. Also interesting is the hormonal activity of Reishi. Its component ganoderol B binds to receptors for androgens (male sex hormones) on the prostate, which can help with the treatment of prostate cancer. Tumour cells are namely stimulated by testosterone, and thus the tumour grows. If the effects of sex hormones are blocked, cancer growth is limited.

It is not possible to omit the fact that many tumour cells become resistant to anti-tumour treatment, i.e., they do not respond to it and survive. Adding Reishi makes cancer cells sensitive to chemotherapeutics again.

Another amazing effect of Reishi is that it limits the undesirable effects of cancer treatment. It supports the renewal of the organism, which is damaged by chemo- or radiotherapy.

Since clinical studies also exist, we must mention them. In one study, patients with lung cancer (36 people) used Ganopoly, which is an aqueous solution of polysaccharides from Reishi. These patients also underwent anti-tumour treatment. In those who used Ganopoly, the immune system was in a better state, and the patients felt somewhat better. In another study with 47 patients with colon cancer, anti-tumour effects were also captured. The quality of life of patients with lung cancer was also investigated. 82 patients undergoing chemotherapy participated in the study, who were divided into groups, where one received a preparation with Reishi and the other a placebo, i.e., an ineffective preparation. Patients with Reishi described a subjective improvement in condition (they did not know they were using Reishi), while patients with placebo did not. They improved physically and mentally, unfortunately, the results were not statistically significant.

Reishi can also be used as prevention of cancer formation. In a Japanese study, extract from Reishi was administered to people with colon adenomas (polyps that can degenerate into cancerous growth), and that was as soon as the diagnosis was determined. 132 patients received Reishi, 102 nothing. After 12 months, a control colonoscopy was performed. In the control group, changes in polyps occurred +0.66, in persons with Reishi -0.42. The total size of polyps in the group without Reishi increased by 1.73 mm, while with Reishi it decreased by 1.40 mm. Reishi therefore not only stabilised the state but even improved it and reduced the risk of cancer outbreak, while in the group without Reishi, a worsening of the state of polyps occurred in some persons.

Oxidative stress / free radicals

Oxidative stress is caused by increased production of free radicals. Radicals are also formed under normal conditions, e.g., during metabolism, energy production in the cell, etc. In the event that the organism is exposed to stress (harmful substances, infections...) higher production of free radicals occurs. Production exceeds the organism's ability to neutralise free radicals. Free radicals react with many compounds, including lipids in cell membranes and DNA. This accelerates ageing, causes inflammation, increases the risk of cancer, etc. Substances in Reishi have significant antioxidant properties. These are mainly flavonoids, phenols, polysaccharides, etc. Antioxidant abilities can be tested in solutions, but also on animal models. Where the value of malondialdehyde can be tested, the concentration of which grows during lipid peroxidation by free radicals (reaction of fats in membranes). Reducing oxidative stress acts as prevention of many diseases, including cancer, degenerative diseases of the central nervous system, etc.

Reishi against diabetes

Diabetes (diabetes mellitus) is a disease associated with increased levels of sugar in the blood, hyperglycaemia. Two basic types of diabetes are commonly distinguished, namely type I and II. Type I manifests itself already in childhood, it is caused by an autoimmune inflammation that damages the pancreas. This is associated with a decrease in insulin production. We see type II in older people who are overweight or obese (however, obese children can also suffer from it), here either the pancreas can be damaged and insulin production decreased, but we often encounter the fact that there is enough insulin, only cells do not respond to it, i.e., insulin resistance is present. Increased values of sugar in the blood damage the lining of blood vessels, damage nerves, the immune system, this leads to a higher incidence of cardiovascular diseases in diabetics, damage to kidneys, retina, neuropathic pain, slowing of healing, etc.

Anti-diabetic effects of Reishi are most often tested on mice or rats, in which a state similar to diabetes is caused. If Reishi is administered to a part of the mice/rats, a decrease in glycaemia occurs, an increase in insulin production, and a restoration of cell sensitivity to insulin also occurs. A very interesting study brought evidence that Reishi improves the composition of intestinal microflora and thus also influences metabolism. Even just thanks to the manipulation of microflora using Reishi, a significant improvement in condition occurred in rats with diabetes. Diabetes was brought under control.

There are also clinical studies. We can mention one with 71 patients with type II diabetes who used ganopoly for 12 weeks. Afterwards, their health condition was checked, it was found that the patients had glycaemia under control, values of glycated haemoglobin decreased (if there are long-term higher levels of sugar in the blood, sugar binds to red blood pigment). Reishi can also mitigate the impacts of diabetes. This is evident mainly in diabetic kidney damage. Damaged kidneys react to the administration of Reishi with an improvement in functions, etc.

Reishi fights blood fats and heart protection

Increased values of fats in the blood are associated with a high risk of cardiovascular diseases. Fats namely deposit in blood vessel walls, which damages them, causes inflammation, narrows the lumen of blood vessels, etc. Atherosclerosis develops, which is also accompanied by high blood pressure, the incidence of heart or brain attack. Fats in the blood can in many cases be regulated by diet and lifestyle with sufficient movement. However, there are cases that are genetically conditioned and diet does not help.

With the first cases, however, Reishi can also help. Experiments are most often conducted on rodents that are fed a high-fat diet, which leads to an increase in fats in the blood. Reishi is then administered to a part of the rodents and not to a part, and the state between the two groups is compared. All conducted studies turned out the same. In groups with Reishi, a decrease in total cholesterol, bad LDL cholesterol, triglycerides, and an increase in good HDL cholesterol occurred. Since studies with volunteers also exist, we must mention them. 26 patients with type II diabetes, overweight, and increased fat value participated in one. Using Reishi led to a decrease in fats (decrease in LDL, triglycerides) and also to the regulation of glycaemia in them.

If we look at the heart, a study of patients with angina pectoris and atherosclerotically changed blood vessels was conducted. There were 34 patients in it who used Reishi, a decrease in oxidative stress and total cholesterol. Its entry and exit values were: 205.49±48.49mg/dl and 182.11±73.81mg/dl.

Liver and digestive system under the protection of Reishi

The liver, although not as much attention is paid to it, is indispensable for life and its failure is associated with death. The liver is damaged by many substances or infections, which leads to mild but permanent inflammation, scarring, and tissue remodelling, which becomes non-functional, i.e., fibrosis and cirrhosis occur.

Furthermore, it was confirmed in many studies that Reishi mitigates the impacts of toxic substances on the liver. Rodents are exposed to substances that are toxic to the liver, e.g., carbon tetrachloride, alcohol, mushroom poisons, etc. A part is treated with Reishi and a part is not. In untreated ones, a massive increase in liver enzymes in the blood is always evident, these are released from damaged liver cells, i.e., ALT, AST, increased oxidative stress, and liver tissue is inflammatorily changed. If rodents receive Reishi, changes can appear, but changes are never as significant as in rodents without Reishi. In some cases, Reishi leads not only to stopping the worsening but also to an improvement in the state of the liver.

Here we must also mention the positive influence of Reishi on the mucosa of the intestinal system, including the stomach. Reishi modulates microflora, thereby reducing the risk of stomach ulcers and cancer.

Besides the liver, Reishi has a positive influence on the intestinal mucosa, as we mentioned already above in the chapter about the immune system. It supports healthy microflora, increases the resistance of the mucosa, reduces its permeability. Reishi is also beneficial for the stomach.
