Reishi Medicinal Mushrooms Heinz Lüscher


The Reishi mushroom, also known as Ganoderma lucidum and Lingzhi, is a fungus that grows in various hot and humid locations in Asia. It is true king among the medicinal mushrooms. It is a natural alternative to cortisone, has anti-inflammatory properties, strengthens the liver, has a calming, stabilising effect and strengthens the immune system. A true lucky mushroom, then, for those who know about this and use it.

The Reishi (Japanese "divine mushroom"), Latin Ganoderma lucidum or Lingzhi, ranks among the most important medicinal mushrooms and probably among the oldest medicines in the world. It can be found all over the world and grows mainly on deciduous trees, preferably on oaks. Reishi is not an edible mushroom, it tastes bitter and its consistency is hard. It is therefore a pure medicinal mushroom. 

In China, it has been used for medical purposes for thousands of years and almost everything written in ancient China about the effects of Reishi has been proven in modern scientific studies. In China the medicinal mushroom is called "Ling Zhi", which means, "Divine mushroom of immortality". In ancient Chinese medicine Reishi was classified as one of the highest quality remedies, which were also called "herbs of God". It was placed at the top of the list before all other plants and was even called the "King of Medicinal Plants".

In China and other Asian countries, the mushroom is still considered a symbol of happiness. Anyone who knows it could actually call himself a lucky fungus, because there is hardly another medicinal fungus with such a wide range of applications. It is used successfully in liver diseases, allergies, inflammations of all kinds, but also heart and lung diseases and even in the fight against cancer! The ingredients of Reishi offer an arsenal of active ingredients, a whole pharmacy so to speak. Accordingly, the modes of action and applications of Reishi are extremely diverse and complex. About 400 bioactive substances have been detected to date. It is therefore worth taking a closer look at this unique medicinal mushroom!


Some 150 triterpenes are found in Reishi. These are chemically and pharmacologically extremely interesting and diverse secondary plant compounds. These protect the Reishi itself against infestation by microorganisms and have a strong antibacterial and anti-inflammatory effect on the body. Due to their chemical structure, terpenes and the substances derived from them, such as triterpenes, can be used for all diseases in which steroid hormones - such as cortisone - are normally used. However, in contrast to cortisone, Reishi therapies have no side effects! The release of histamine, which is responsible for swelling, redness and itching in allergies, is curbed. With its high content of triterpenes, this medicinal mushroom has an extremely favourable effect on all inflammations in the body.  Triterpenes can also strengthen the cardiovascular system, lower high blood pressure (hypertension) and prevent or counteract liver insufficiency.


Reishi contains more than 100 different highly effective polysaccharides. Chemically speaking, polysaccharides are so-called multiple sugars. Polysaccharide molecules consist of at least 10, but often several thousand, chemically linked monosaccharides. Polysaccharides have many different functions in the body. A special group of polysaccharides found in this vital fungus stimulates the response of the immune system. They stabilise the immune system so well that numerous pathogens no longer stand a chance. This activation of the immune system prevents diseases on the one hand and strengthens and supports the body's self-healing abilities in the case of existing (chronic) diseases on the other.

As Reishi stabilises the immune system, it also helps with diseases caused by an exuberance of the immune system, such as allergic reactions or autoimmune diseases. If the immune system overreacts or reacts incorrectly, the Reishi dampens this reaction and reduces the response to a healthy level.


Adenosine, which is found in this medicinal mushroom, has a calming and relaxing effect on the muscles and thus has the opposite effect to the neurotransmitter acetylcholine. The transmission of stimulation between the nerve and the contraction of the smooth muscles is thus reduced. In Asia, many people drink Reishi tea regularly in the evening because it makes them relaxed and sleepy. This is attributed to the fact that the medicinal mushroom also has a sedative (calming) effect on the brain cells and helps to bring the central nervous system (CNS) to rest. The good thing about Reishi tea is that it does not have a hypnotic or narcotic effect like conventional sleeping pills and is not addictive even with prolonged use.

Further Ingredients

It is also worth mentioning the various nucleotides, sterols, amino acids, alkaloids, antioxidants, vitamins and minerals (e.g. a lot of iron) contained in Reishi mushrooms. Among the trace elements found in this fungus, germanium is of medical importance. With such a wide range of active substances and ingredients, it seems important to me to point out that the healing effect of Reishi is not due to individual isolated active substances, but to the wonderful overall combination of ingredients formed by the creator of the fungus.

Reishi spores

It is interesting to note, that, in the Reishi spores, the active ingredients are found in their most concentrated form. The spores are therefore regarded as the most valuable part of the fungus. The oval yellow-brown Reishi mushroom spores, which are used by the mushrooms for asexual reproduction, show a much higher bio-activity of the ingredients mentioned above compared to the level of ingredients found in other parts of the mushroom.

Areas of Use for the Reishi Medicinal Mushroom

The Reishi healing mushroom has an extremely wide area of application, here we discuss a few options:

  • Liver: The Reishi regenerates the liver and has a blood cleansing and detoxifying effect. It is particularly effective in chronic hepatitis and helps with liver problems.
  • Respiratory tract: In chronic respiratory diseases with reduced oxygen supply, Reishi is also helpful because it improves oxygen saturation in the blood. It can therefore be used for asthma, chronic bronchitis and shortness of breath.
  • Heart: The improved oxygen supply also has a positive effect on heart activity, because the oxygen supply to the heart muscle is also improved. This allows the medicinal mushroom to be used, for example, for narrowed coronary vessels (coronary heart disease), cardiac arrhythmia, severe fluctuations in blood pressure and cardiac dysfunction.
  • Sports: These could also be an interesting topic for athletes. The Chinese are already using the fungus to legally increase the performance of their athletes. Tests with mountaineers have also shown that taking Reishi increases tolerance to oxygen shortages and is effective against altitude sickness.
  • Skin: Skin diseases can also benefit from the vital mushroom. The detoxifying and blood cleansing effect relieves all forms of skin diseases (e.g. neurodermatitis). The anti-inflammatory and anti-allergic effect also play an important role.
  • Immune system: The Reishi medicinal mushroom has cytotoxic or cell multiplication inhibiting properties and can therefore be used in the fight against viruses and bacteria, in addition to, inhibiting the growth of cancer cells. The immune system is strengthened and supported, which is also useful for allergies and autoimmune diseases. 

In summary, I can recommend the Reishi medicinal mushroom for the following clinical conditions:

  • weakened or excessive immune system responses (frequent "ailments", infections, allergies, autoimmune diseases)
  • heart diseases (hypertension, coronary heart disease, arrhythmia)
  • liver diseases (chronic hepatitis, hepatic insufficiency, cirrhosis of the liver)
  • (Chronic) respiratory diseases (e.g. bronchitis, asthma)
  • stomach ulcers
  • sleeplessness
  • kidney inflammations
  • Joint inflammation (arthritis)
  • (Inflammatory) skin diseases
  • fibromyalgia
  • cancer
  • General disease prophylaxis
  • Prevention of altitude sickness
