Lion's Mane & Reishi – what medicinal mushrooms can really do

Medicinal mushrooms have been an integral part of traditional medicine in many cultures for millennia. Two species are particularly prominent today: Lion's Mane (Hericium erinaceus) and Reishi (Ganoderma lucidum) . But what is scientifically proven? What active ingredients do these mushrooms contain? And how can they be used? In this article, we examine the current state of research, potential applications, and clarify myths and facts.

1. Introduction: What are medicinal mushrooms?

The term "medicinal mushrooms " refers to mushroom species to which health-promoting properties are attributed. This knowledge originally stems primarily from Traditional Chinese Medicine (TCM), where mushrooms such as Reishi , Shiitake , Maitake , and Cordyceps have been used for centuries. In recent decades, these mushrooms have also become increasingly popular in the Western world.

Key facts:

• Medicinal mushrooms contain a variety of bioactive substances such as polysaccharides, triterpenes, sterols and secondary plant compounds.

• The effect always depends on the type, quality and dosage of the mushroom extract.

• Many claims about medicinal mushrooms have not yet been conclusively scientifically proven.

2. Lion's Mane (Hericium erinaceus) - The hedgehog's mane

2.1 Botanical & Traditional Uses

Lion's mane , also known as hedgehog mushroom , is a white, strikingly shaggy edible mushroom found in Europe, North America, and Asia. In China, it has been considered a delicacy for centuries and is revered there as the "mushroom of the gods."

Traditional uses:

• Promoting digestion

• Strengthening life energy (“Qi”)

• Support for weakness and exhaustion

2.2 Ingredients and Bioactivity

Lion's Mane contains several pharmacologically interesting substances:

• Erinacine and hericenone: These substances are associated with promoting nerve growth (NGF – Nerve Growth Factor).

• Polysaccharides (beta-glucans): Immunomodulating effect.

• Phenol compounds: Antioxidant properties.

2.3 Scientific research

Neuroprotective effects:

• Some preclinical studies (especially in animals and in vitro) suggest that Lion's Mane may support the growth and regeneration of nerve cells.

• In a small human study from Japan (Mori et al., 2009), improvements in cognitive function were observed in older adults with mild cognitive impairment after taking Lion's Mane for 16 weeks. However, the effects disappeared after discontinuation.

Possible areas of application:

• Improved memory and concentration

• Support for mild cognitive impairments

• Mood improvement (initial studies suggest antidepressant effects)

Important limitation:
Many of these effects have so far only been demonstrated in the laboratory or in small groups of people. Meaningful, large-scale clinical studies are still lacking.

2.4 Side effects and safety

• So far, there is little evidence of serious side effects in healthy people.

• Allergic reactions are rare, but possible.

• People with mushroom allergies or asthma should only take Lion's Mane after consulting a doctor.

3. Reishi (Ganoderma lucidum) – The “mushroom of immortality”

3.1 History and traditional use

The Reishi mushroom, also known as "Ganoderma lucidum," has a legendary reputation in Chinese medicine. There, it is considered a symbol of longevity, vitality, and mental clarity. In Traditional Chinese Medicine (TCM), Reishi (Ling Zhi) is used to strengthen the immune system, promote calmness, and reduce stress.

Traditional areas of application:

• Strengthening the immune system

• Improving sleep quality

• Increased life energy

3.2 Ingredients

Reishi contains over 400 different bioactive substances, including:

• Triterpenes (Ganoderic Acids): Anti-inflammatory and antioxidant properties.

• Polysaccharides (beta-glucans): Immunomodulatory effect.

• Sterols: Support of the hormonal balance.

3.3 Scientific research

Immune system and inflammation

• Numerous laboratory studies indicate that Reishi extracts can increase the activity of immune cells such as macrophages and NK cells.

• Initial clinical trials have observed an improvement in people with chronic bronchitis and asthma.

• The anti-inflammatory effect is well documented in animal and cell studies.

Stress and sleep

• Reishi is traditionally used as a "calming agent". Some human studies suggest an improvement in sleep quality (e.g., through modulation of the GABA system).

• Studies show a possible reduction in stress symptoms, but the data is still limited.

Oncological research

• In Asia, Reishi is often used as a complementary therapy to cancer treatment.

• Some clinical studies suggest a possible improvement in quality of life and a reduction in side effects of chemotherapy.

• Important: There is currently no evidence that Reishi can cure or prevent cancer!

3.4 Side effects and safety

• Reishi is considered safe when taken in moderate doses.

• At very high doses (>4g/day) or long-term use, side effects such as dry mouth, stomach upset or skin rash are rarely described.

• Pregnant women, breastfeeding women and people with blood clotting disorders should only take Reishi after consulting a doctor.

4. Similarities and differences between Lion's Mane & Reishi

Similarities:

• Traditional use in Asian medicine

• Both contain beta-glucans, which can have immunomodulatory effects.

• Promising approaches in modern research, but no conclusive clinical evidence yet for many postulated effects.

• Low potential for side effects when used correctly.

Differences:

5. Myths & Facts – What medicinal mushrooms can really do

Many sometimes outlandish claims circulate about medicinal mushrooms. Here's a realistic fact check:

Myth 1: "Medicinal mushrooms are a miracle cure for all diseases."

Fact:
Medicinal mushrooms can make a supportive contribution to health, but are not a substitute for medical treatment or a healthy lifestyle.

Myth 2: “Reishi cures cancer.”

Fact:
To date, there is no scientific evidence that Reishi cures cancer. It may improve the quality of life for some patients, but should never be used as a sole therapy.

Myth 3: "Lion's Mane makes you intelligent."

Fact:
Initial studies suggest an improvement in cognitive function, particularly in cases of mild impairment. However, a "brain-boosting" effect in healthy individuals has not yet been proven.

Myth 4: "Medicinal mushrooms are completely free of side effects."

Fact:
As with all natural substances, medicinal mushrooms can also cause side effects, especially in cases of overdose or pre-existing conditions.

6. Quality and correct use of medicinal mushrooms

Not all mushroom extracts are the same. The following points are crucial for optimal effectiveness:

What should you pay attention to when buying?

• Certified quality: Organic certification, residue testing for heavy metals and pesticides

• Full extracts: Combination of fruiting body and mycelium components for a broader spectrum of active ingredients

• Standardized levels: Indication of the active ingredient concentration (e.g., polysaccharides, triterpenes)

• Manufacturer transparency: origin, cultivation, processing

Administration & Dosage

• The recommended dosage varies depending on the product and concentration.

• In general: Start with a low dose and increase it if well tolerated.

• It is best taken on an empty stomach or between meals.

• A doctor should always be consulted in the case of chronic illnesses or when taking medication.

7. Summary: What medicinal mushrooms can really do (today)

Lion's Mane and Reishi are promising representatives of medicinal mushrooms whose effects are increasingly being scientifically investigated. There are particularly positive indications for supporting the immune system, addressing cognitive impairments, and as an adjunct to stress management.

The current status:

• Many of the effects traditionally described are supported by modern research, but are often not yet conclusively proven.

• Medicinal mushrooms can be a valuable component for health and well-being – especially as part of a healthy lifestyle.

• Proper use requires that quality, dosage, and possible interactions are taken into account.

Conclusion

Medicinal mushrooms like Lion's Mane and Reishi offer fascinating possibilities for naturopathy and prevention. However, they are not a panacea and should always be viewed with scientific caution.
