The Most Common Medicinal Mushrooms: An Overview of Their Properties and Traditional Uses

The Hidden Gateway to Health? Let’s Talk About the Most Common Medicinal Mushrooms

Forget everything you thought you knew about mushrooms. This is not another routine article telling you to “eat healthy.” We are going to dive deep — into a world of ancient, remarkable organisms that have occupied scientific research in recent years.

If you feel you need a genuine boost. If you are looking for that small edge. Or maybe you are simply curious about one of nature’s best-kept secrets — you are in exactly the right place.

Get ready, because this journey will not only broaden your horizons. It will give you all the tools and knowledge you need to understand why the world is once again taking an interest in medicinal mushrooms — and why you, too, will probably join in soon.

The Myths, the Reality and the Science: Medicinal Mushrooms Are Not Just Decoration

When most of us hear the word “mushrooms,” we immediately think of pizza. Or maybe a fine plate of portobellos. Well, think again. Deep in the forests, on the trunks of decaying trees, real treasures hide — treasures that traditional medicine in the Far East has used for thousands of years. Not strange organisms that sprout after the rain, but entire biochemical factories.

They have been gaining momentum in recent years. And it is not because of a passing Instagram trend, but thanks to scientific research that is beginning to reveal what the ancients knew long ago. These mushrooms are studied in the context of supporting, balancing and maintaining the function of various systems in the body.

And let’s be honest: who doesn’t want a little more energy? A little less stress? A balanced immune system? Exactly. So let’s dive deep, behind the scenes of the most common mushrooms.

Not sure which mushroom to start with? You can read the full guide to medicinal mushrooms or look up any unfamiliar terms in our glossary.

1. Reishi: The “Mushroom of Immortality” — Legend or Scientific Reality?

If there is one mushroom that has earned a royal title, it is Reishi (Ganoderma lucidum). It is called the “mushroom of immortality” or the “queen of mushrooms.” And as you can imagine, it did not receive that title for nothing. In Traditional Chinese Medicine it is considered a kind of elixir — one associated with longevity and serenity.

So what is its secret? Reishi is rich in bioactive molecules: triterpenes, polysaccharides (β-glucans) and antioxidants. These compounds are the reason it is so widely studied.

• Immune-system support: It is studied in the context of regulating the immune system — not simply to “boost” it, but to balance it (structure-function). In other words, in research it is examined in the context of supporting a balanced immune response.
• Stress reduction and sleep quality: Sounds too good to be true? Reishi is an adaptogen. What does that mean? That in tradition and in research it is studied in the context of the body’s adaptation to stress, a sense of calm, and sleep. Many people report better sleep quality after regular use.
• Heart and cardiovascular health: Preliminary studies examine Reishi in the context of balancing blood pressure and cholesterol levels. This does not mean giving up medical care — it is a dietary supplement, not a substitute.

A small tip for life: If you feel you are on edge, or you simply cannot fall asleep the way you should, Reishi is one of the common mushrooms worth getting to know.

Quick Q&A on Reishi:

Q: Can Reishi cure cancer?
A: It is important to be clear: Reishi is not a cancer medicine and is not a substitute for any medical treatment. Medicinal-mushroom extracts are dietary supplements only. Some studies (preliminary, in part in the laboratory or on isolated compounds) examine Reishi in the context of supporting immune-system function, but no therapeutic effect should be inferred from this. Always consult a physician.

Q: How long does it take to feel the effect of Reishi?
A: The effect of medicinal mushrooms is usually cumulative. You may feel a slight change within a few weeks, but a more noticeable change is generally reported after several months of regular use.

2. Lion’s Mane: Not Just for Cats — For Your Brain!

Its name, Hericium erinaceus, sounds complicated. But its appearance? Simply stunning. It looks like a mass of white, fluffy hair — or like a lion’s mane. Hence its name. And yes, it is not only beautiful. It is interesting. Very interesting.

Lion’s Mane receives research attention for its properties in the context of brain health. Yes, you read that right. The brain.

• Nerve growth factor (NGF): This is the big one. Lion’s Mane contains unique compounds such as hericenones and erinacines — substances that have been studied in the context of encouraging NGF production. And NGF is like a fertilizer for the brain; it is associated with the growth and repair of nerve cells. Sounds like science fiction? It is real research, largely preliminary.
• Cognitive support: Who doesn’t want better memory? Sharper focus? Lion’s Mane is studied in this context. It is studied in the context of degenerative brain conditions, but for healthy people, too, it is examined in the context of “focus” in an age of distractions.
• Digestive-system protection: And while we are on the subject of things you did not expect, Lion’s Mane has also been studied in the context of digestive-system health. It has been studied in the context of protection against ulcers and of reducing gut inflammation.

Did you know? In Buddhism, Lion’s Mane was considered a mushroom that helps with concentration and meditation — perhaps because of its ability to sharpen awareness. Who knows?

3. Chaga: Nature’s Black Diamond — Does It Shine for You Too?

Chaga (Inonotus obliquus) does not look like an ordinary mushroom. It resembles a piece of burnt charcoal, or a chunk of scorched wood. It grows mainly on birch trees in cold regions. And it is certainly not as photogenic as its sister Lion’s Mane. But its beauty lies within. Deep within.

It earned the nickname “black diamond” thanks to being a rich source of antioxidants.

• A rich source of antioxidants: Chaga is probably one of the richest antioxidant sources in nature. It contains quantities of substances such as superoxide dismutase (SOD), polysaccharides and betulinic acid. These are studied in the context of free radicals and oxidative damage to cells.
• Immune support: Like many mushrooms, Chaga is also studied in the context of the immune system. It is studied in the context of supporting the body’s coping with various pathogens.
• Reducing inflammation: Chronic inflammation is considered a common denominator in many diseases of the modern age. Chaga has been studied in the context of reducing markers of inflammation in the body.

An anecdote: In Russia, Chaga was considered in folk tradition a grandmother’s remedy for almost everything. The Russian grandmothers apparently knew a thing or two. (This refers to traditional, folk use only — not a medical indication.)

Quick Q&A on Chaga:

Q: How do you consume Chaga?
A: Chaga is usually consumed as an extract, a tea powder, or a supplement. Because of its hard texture, it is not eaten like ordinary culinary mushrooms.

Q: Are there side effects to Chaga?
A: Chaga is considered safe for most people. However, because of its relatively high oxalate content, people prone to kidney stones are advised to consume it with caution and under medical supervision.

4. Cordyceps: The Energy Nature Kept for You — Who Wants to Be Superman?

Cordyceps (Cordyceps sinensis / militaris) is a slightly different mushroom. Mysterious. And, to be honest, a little unsettling in its origins. In nature it is parasitic on larvae. Yes, you read that correctly — it grows out of the body of a larva. But don’t worry: most of the Cordyceps you find today is cultivated in a laboratory on completely vegan substrates, without any larvae. Take a deep breath.

Don’t let the strange origin put you off. Cordyceps is studied in the context of energy and endurance.

• Energy and endurance: Athletes and adventurers around the world swear by it. It is studied in the context of improving performance. Studies examine whether it can improve the body’s ability to use oxygen and increase production of ATP (adenosine triphosphate) — the cell’s main energy molecule.
• Respiratory-system support: If you struggle with breathing, or simply want to improve lung capacity, Cordyceps has been studied in this context. It has been studied in the context of asthma symptoms and bronchitis.
• Kidney health: In Chinese medicine, Cordyceps was traditionally used to support the kidneys and sexual health, and modern research examines these directions.

Who is it for? If you feel you need an energetic push in the morning, or you engage in intense physical activity, Cordyceps may be one of the mushrooms worth getting to know.

5. Turkey Tail: Not Just for Pets — For Your Immune System!

Turkey Tail (Trametes versicolor / Coriolus versicolor) is a colorful, beautiful mushroom that looks like the tail of a turkey — or perhaps like a forest elf’s ear. It is very common, and grows on almost every continent. But its beauty is not only external.

It may not be the flashiest star on the red carpet of medicinal mushrooms, but it is certainly the subject of extensive research — especially in everything related to the immune system.

• Unique polysaccharides: Turkey Tail is rich in specific polysaccharides such as PSK (Polysaccharide K) and PSP (Polysaccharopeptide). An important clarification: PSK (also known as Krestin) and PSP are isolated, regulated pharmaceutical compounds (mainly in Japan, where they were studied and are used as supportive care alongside chemotherapy and radiotherapy) — and not the mushroom extract sold as a dietary supplement. These are two entirely different things from a regulatory and research standpoint.
• Gut support: Turkey Tail is also studied in the context of gut-microbiome health. It contains natural prebiotics that nourish the beneficial bacteria — and gut health is an important foundation for overall health.
• Studied in an antimicrobial context: It has also been studied in the context of activity against viruses and bacteria, particularly in the transitional seasons.

The bottom line: If you tend to get sick often, or you simply want to support your immune system, Turkey Tail is a common mushroom worth getting to know.

Quick Q&A on Turkey Tail:

Q: Is Turkey Tail suitable for children?
A: In general, medicinal mushrooms are considered safe for children too, but it is always recommended to consult a pediatrician or a qualified practitioner before giving supplements to children — especially to set the correct dose.

Q: Can you take several medicinal mushrooms together?
A: Absolutely. Many people combine several mushrooms together for a broader spectrum of benefits. This is called “stacking.” For example, Reishi for calm, Lion’s Mane for the brain, and Cordyceps for energy.

6. Shiitake: Not Only in the Kitchen — A Health Surprise!

Most of us know the Shiitake mushroom (Lentinula edodes) from the kitchen — from the wok, from the Asian soup. And it is indeed a tasty, juicy mushroom. But beyond being a culinary star, it is also studied in a health context. You simply would not have known it until you dive deeper.

Shiitake was a key ingredient in Chinese and Japanese medicine for thousands of years. And not only for its taste.

• Immune support: Shiitake contains a unique polysaccharide called Lentinan. An important clarification: Lentinan is an isolated compound extracted from Shiitake and studied on its own — it is not the same as the mushroom extract sold as a dietary supplement. Lentinan has been studied in the context of stimulating the activity of immune-system cells.
• Heart health: Studies examine Shiitake in the context of cardiovascular health. It has been studied in the context of cholesterol levels and blood flow.
• Studied in an anti-inflammatory context: Like many of the other mushrooms, Shiitake has also been studied in the context of anti-inflammatory properties.
• Vitamin D: No less important, Shiitake is one of the few plant sources of vitamin D (especially when exposed to sunlight). And vitamin D, as you know, is important for bone health, the immune system and mood.

Did you know? In Japan, Lentinan — an isolated compound extracted from Shiitake — was studied and approved as supportive care alongside oncology treatments. It is important to emphasize again: this refers to an isolated, regulated pharmaceutical, and not the mushroom extract sold as a dietary supplement.

7. Maitake: The “Dancing Mushroom” — and Health!

Maitake (Grifola frondosa), or the “dancing mushroom” in Japanese, got its name because people are said to have danced for joy when they found it in nature, owing to its great value. And it is indeed a cause for celebration — especially for the immune system and blood-sugar levels.

It grows at the base of old oak trees, and its appearance resembles clustered cabbage leaves. But don’t let the appearance fool you.

• Immune support: Like its companions, Maitake is studied in the context of immune support. It is rich in β-glucans, particularly an isolated compound known as the “Grifola frondosa fraction” (D-fraction) — it is important to note that this is an isolated compound studied on its own, and not the whole mushroom extract. In research it is examined in the context of stimulating immune-system cells such as NK (Natural Killer) cells and macrophages.
• Balancing blood-sugar levels: This is an interesting research direction. Preliminary studies examine Maitake in the context of blood-sugar levels and insulin sensitivity. It is important to emphasize: research in this area is preliminary, and it should not be relied upon for managing diabetes or pre-diabetes — consult a physician.
• Blood pressure: There are preliminary studies that also examine Maitake in the context of blood pressure.

Heads up! If you are looking for a mushroom that offers both culinary benefits and health interest, Maitake is certainly a strong candidate.

Quick Q&A on Maitake:

Q: Can medicinal mushrooms replace medications?
A: Absolutely not. Medicinal mushrooms are natural dietary supplements that can support health and quality of life. They are not a substitute for prescription medications, conventional medical treatments or professional advice. Always consult a physician before any change to your treatment or the addition of a new supplement to your diet.

Q: How do you choose a quality medicinal-mushroom supplement?
A: Look for extracts, not ground mushroom powders. Make sure the product states the percentage of active polysaccharides or β-glucans, and that it is backed by lab testing (COA) and transparent quality control. You can read about this on our transparency page. Prefer products from reputable companies with third-party testing for the absence of contaminants.

3 Facts You Didn’t Know About Mushrooms (and They Have Nothing to Do with Pizza)

Thought we were done? We have only just scratched the surface of the wonderful world of mushrooms. Here are a few more facts that will knock you off your chair and make you look at the fungal kingdom with awe. And again — nothing to do with pizza.

1. They are closer to humans than to plants: Yes, it sounds strange. But genetically, mushrooms are closer to animals than to plants. Their cellular structure and the way they obtain their food (they do not perform photosynthesis) are completely different from plants. They are a kingdom of their own — a unique kingdom.
2. They are giant recyclers: Mushrooms are nature’s chief decomposers. They break down dead organic matter and return essential nutrients to the soil. Without mushrooms, the earth would be choked with organic waste, and the soil would be emptied of all its goodness. They are the quiet workers that keep the ecosystem functioning. Think about that the next time you see one.
3. They are an amazing underground communication network: The mycelium — that hidden part of the mushroom that develops underground — is a vast network of tiny fungal threads. It connects plants and trees, allowing them to transfer information and nutrients, and even to warn one another of pests. It is like an underground “wood-wide web.” Simply amazing.

Is This for You? A Final and Important Word

So now you know. Medicinal mushrooms are much more than just “hype.” They are an ancient heritage accompanied by modern research. They offer interesting research directions in the context of supporting health, balancing the body and calming the mind. They are dietary supplements — not a medicine, and not a substitute for medical care.

Is it right for everyone? That is an excellent question. As with any natural supplement, it is important to approach the matter with care and judgment. Consult a professional — a physician, a naturopath, someone who understands, someone who can tailor the right dose and the right combination and make sure it is safe for you.

Remember, the key to health lies in the combination: a balanced diet, physical activity, good sleep, and attention to your mental state. Medicinal mushrooms can be one more tool in your health arsenal.
