Agaricus Blazei Murrill: Benefits, Active Ingredients, and Applications in Mycotherapy
Agaricus blazei Murrill (ABM) is an important medicinal mushroom native to the Piedade region in São Paulo, Brazil. It is one of the most extensively studied medicinal mushrooms in the world. Research focuses on immunomodulation, supportive cancer therapy, metabolic health, and antioxidant protection. Its scientific reputation is based on a remarkable observation: the population of Piedade exhibited unusually low rates of cancer, infections, and degenerative diseases in adulthood. Researchers identified Agaricus blazei murrill as a significant dietary factor.
Japanese researchers began conducting systematic studies in the 1960s. They isolated the fungus’s most important active compounds and confirmed its powerful immunomodulatory properties. Decades of research in Brazil, Japan, and Europe have since established a solid evidence base for its clinical relevance.
What is Agaricus blazei Murrill?
Agaricus blazei murrill belongs to the mushroom family (Agaricaceae). Biologist William Alphonso Murrill first described it in 1974. Subsequent analyses revealed that it had already been cataloged as Agaricus brasiliensis. In 2005, a DNA sequence analysis confirmed its genetic identity with Agaricus subrufescens Peck, which had been described as early as 1893. The same mushroom was discovered three times independently of one another. The abbreviation ABM is commonly used in scientific literature.
The almond mushroom (ABM) is known by various names. In Japan, it is called Himematsutake. In Brazil, it is called Cogumelo de Deus (God’s mushroom) and Cogumelo do Sol (Sun mushroom), the latter referring to its preference for sunny, open locations. In German, it is known as the “almond mushroom” because of its characteristic almond-like aroma.
In mycotherapy, ABM is classified as an immunomodulatory and adaptogenic medicinal mushroom. Its main areas of application include immune regulation, supportive treatment for cancer, promotion of metabolic health, and antioxidant protection. History and Traditional Uses of Agaricus blazei Murrill
Generations of residents in the Piedade region regularly consumed ABM. Their unusually low rates of cancer and infection attracted scientific interest in the 1960s. Japanese researcher Takatoshi Furumoto traveled to Piedade to investigate this, identified ABM as a consistent dietary factor, and brought samples back to Japan for analysis.
Japanese research teams subsequently isolated the mushroom’s key active compounds, focusing on the beta-1,3/1,6-D-glucan fraction. This polysaccharide complex activated key immune cell populations in a manner that had not previously been described in other mushroom species. The high content and efficacy of ABM’s beta-glucan profile have made it a subject of ongoing clinical interest in oncological and immunological research.
Starting in the 1970s, research was expanded to include antidiabetic properties, antioxidant capacity, and liver-protective effects. Today, ABM is used in integrative mycotherapy treatments in Japan, Brazil, Germany, and throughout Europe.
Key Active Ingredients in Agaricus Blazei Murrill
The health-promoting properties of ABM whole-mushroom powder are due to specific fractions of bioactive compounds. These compounds are responsible for the documented effects in mycotherapy.
Beta-D-glucans are the most important immunologically active polysaccharides in ABM. They stimulate the production of cytokines and interleukins and promote the proliferation and differentiation of macrophages and monocytes. Researchers attribute the majority of the antitumor effect to this component.
Glycoproteins consist of protein and polysaccharide components. In tumor research, the protein component is considered the more active component. Glycoproteins complement beta-D-glucans in immune activation.
The steroids in ABM include ergosterol, blazeispirol A and C, and blazein. Blazeispirol A and C, as well as blazein, have been shown to possess antitumor properties. Ergosterol inhibits the formation of new blood vessels that tumors need to grow—an effect known as antiangiogenesis.
Ergothioneine is a sulfur-containing antioxidant compound found in ABM. It accumulates in tissues with the highest oxidative stress, including nerve tissue and mitochondria. It crosses the blood-brain barrier and is associated with neuroprotective effects. Its role is described in detail in the following section on neurological aspects.
Phenols and glucomannan contribute to antioxidant and metabolic activity. Phenols directly bind free radicals. Glucomannan supports metabolic function.
ABM also contains the highest concentration of the antioxidant enzymes superoxide dismutase, tyrosinase, and catalase ever measured in a medicinal mushroom, as well as the enzyme peroxidase.
Health Benefits of Agaricus Blazei Murrill
The health-promoting properties of Agaricus blazei Murrill are based on its beta-glucan profile, blazein, ergothioneine, and proteoglycans, which exert their effects through proven biological mechanisms. The following sections describe the individual areas of action, the compounds responsible for them, and the underlying research findings or practical insights from mycotherapy.
Cancer Support
Agaricus blazei murrill is one of the most extensively studied medicinal mushrooms in the context of adjuvant cancer therapy. It plays a complementary role: it supports the immune mechanisms involved in recognizing and combating abnormal cell growth. However, it does not replace conventional cancer treatment.
The medical database PubMed contains over 100 scientific articles on ABM and cancer. Research has shown positive results for the following types of cancer: liver cancer, colorectal cancer, stomach cancer, prostate cancer, thyroid cancer, pancreatic cancer, lung cancer, skin cancer, leukemia, and brain tumors.
Blazein was studied for its ability to induce apoptosis in cancer cells and to inhibit angiogenesis—that is, the formation of new blood vessels in tumors. Without angiogenesis, tumor growth is significantly restricted.
The beta-1,3/1,6-D-glucan compound activates natural killer cells and macrophages. ABM also supports bone marrow regeneration following radiation therapy or chemotherapy. The faster sufficient red blood cells are produced again, the sooner symptoms of fatigue subside. The rapid regeneration of white blood cells also strengthens the immune system after chemotherapy.
ABM is used in Japan and Europe as part of integrative cancer treatments, particularly for patients who wish to receive complementary immune support during therapy. Consult a MykoTroph therapist before you begin taking ABM as part of cancer treatment.
Modulation of the immune system
ABM modulates the immune system through its beta-1,3/1,6-D-glucan compound. These beta-glucans activate macrophages and dendritic cells via the pattern recognition receptors TLR2, TLR4, and Dectin-1, thereby triggering a cascade of immune activation.
Macrophage phagocytic activity increases with ABM supplementation. The cytotoxicity of natural killer cells increases. Cytokine signaling—particularly that of TNF-alpha, interleukin-2, and interleukin-12—is supported without triggering an excessive inflammatory response. This balance is why ABM is described as immunomodulatory rather than merely immunostimulatory.
As an adaptogen, ABM can not only boost immune activity but also help restore it to a healthy balance. For this reason, it is also used to treat allergies, asthma, and autoimmune diseases. Myco-therapists use it, among other things, to treat Hashimoto’s thyroiditis, multiple sclerosis, rheumatism, and chronic inflammatory bowel diseases.
Antioxidant protection
Protection of Life
ABM is often described as a liver protectant. It counteracts liver dysfunction, reduces the viral load in hepatitis B, and supports the liver when it is under severe toxic stress. Animal studies show that ABM effectively protects the liver from toxins such as cadmium, carbon tetrachloride, and nitrosamines. Researchers attribute this to an increase in the enzyme glutathione peroxidase.
The beta-glucans in ABM actively lower blood cholesterol and triglyceride levels, thereby reducing fat accumulation in the liver. ABM also strengthens the gut flora, which acts as a protective shield and prevents liver-damaging nutrients from reaching the liver in the first place.
In myco-therapy, ABM is used as part of liver-supportive treatments, particularly for people who have been taking medications that put a strain on the liver for an extended period of time.
Diabetes Management
ABM’s antidiabetic effect begins in the intestines. It inhibits the enzyme alpha-glucosidase, thereby reducing the absorption of carbohydrates by the intestinal mucosa. As a result, the rise in blood sugar after a meal is less pronounced. By stimulating the islet cells of the pancreas, ABM also improves insulin secretion.
ABM protects the beta cells of the pancreas. In type 1 diabetes, these cells are affected by autoimmune processes, and in type 2 diabetes, by inflammatory processes. In myco-therapy, ABM is often combined with Coprinus comatus in diabetes treatment protocols.
People taking blood-sugar-lowering medications should closely monitor their blood sugar levels while using ABM. Consult a MykoTroph therapist to adjust the protocol accordingly.
Support for Allergies and Autoimmune Diseases
ABM reduces the risk of allergies and can alleviate allergic symptoms. Its ingredients inhibit the release of histamine, the key messenger substance involved in allergic reactions. Mast cells in the skin and mucous membranes release histamine upon contact with an allergen. Histamine increases the permeability of blood vessels, which can lead to their dilation and, in severe cases, to bronchospasm and shortness of breath. ABM counteracts these reactions by reducing histamine release.
Regular consumption of ABM mushroom powder made from the whole mushroom has an immunomodulatory effect. Excessive immune responses, such as those that occur with allergies, are suppressed. Experts often recommend a combination of ABM and Reishi to people with allergies, as these two valuable mushrooms complement each other perfectly in their immune-modulating effects.
In autoimmune diseases, ABM affects the population of regulatory T cells. These regulatory T cells prevent the immune system from attacking the body’s own tissues. People with autoimmune diseases should consult a MykoTroph therapist before starting ABM.
Antiviral and antibacterial effects
ABM supports antiviral and antibacterial defense by activating macrophages and natural killer cells through beta-glucan. The phagocytic activity of macrophages is enhanced by taking ABM, which improves the elimination of bacterial invaders. The cytotoxicity of NK cells toward virus-infected cells increases.
ABM has proven effective in combating hepatitis B and C viruses. Taking this medicinal mushroom can also prevent an existing infection from becoming chronic, thereby offering some protection against liver cirrhosis.
In mycotherapy, ABM is used to support recovery from recurrent infections and to maintain immune function during periods of high exposure or physical stress.
Neurological and Cognitive Support
Ergothioneine is the primary active ingredient responsible for ABM’s neuroprotective effect. It is a sulfur-containing antioxidant compound that crosses the blood-brain barrier. Once it reaches the central nervous system, it accumulates preferentially in nerve tissue and in the mitochondria.
In nervous tissue, ergothioneine scavenges reactive oxygen species, protects mitochondrial membranes from oxidative stress, and reduces neuroinflammatory signals. Scientists have discovered specific transport systems for ergothioneine in human cells and mitochondria, suggesting that, from an evolutionary perspective, this compound has long been an integral part of human biochemistry.
Low ergothioneine levels are associated with neurodegenerative diseases such as Parkinson’s and Alzheimer’s. Parkinson’s patients are known to have very low ergothioneine levels, which suggests increased oxidative stress and a heightened need to protect the remaining nerve cells.
Higher blood levels of ergothioneine are associated with better cognitive performance. Studies in animal models suggest that it may support memory and reduce symptoms of cognitive impairment. It also has anti-inflammatory effects in the central nervous system.
The beta-glucan activity of ABM further supports neurological health by reducing systemic inflammation that can cross the blood-brain barrier and enter the central nervous system. Chronic neuroinflammation contributes to cognitive decline and neurodegeneration.
In myco-therapy, ABM is used to support cognitive clarity, mental endurance, and neuroprotection under conditions of high oxidative or inflammatory stress. It is often combined with Hericium and Reishi in treatments designed to support neurological health.
Support for the cardiovascular system and blood pressure
ABM supports cardiovascular health by providing antioxidant protection for the arterial walls, through the effects of beta-glucan on lipid metabolism, and by helping to regulate blood pressure.
ABM actively lowers blood cholesterol and triglyceride levels. Elevated LDL and triglyceride levels are major risk factors for atherosclerosis and cardiovascular events. ABM also has proven antithrombotic properties. Ergothioneine and antioxidant compounds protect the vascular endothelium from oxidative stress, a major mechanism underlying high blood pressure and arterial stiffness.
ABM is not a substitute for prescribed cardiovascular medications or lifestyle changes. Consult a MykoTroph therapist for appropriate complementary measures to support your cardiovascular treatment.
Who can benefit from the medicinal mushroom Agaricus Blazei Murrill?
The active ingredient profile of Agaricus blazei Murrill makes this mushroom relevant for a wide range of health applications. Its immunomodulatory, antioxidant, metabolic, and neuroprotective mechanisms address the underlying biological processes rather than merely treating individual symptoms. The following groups of people benefit most from taking ABM mushroom powder. Cancer patients
Cancer patients who are undergoing treatment or are in remission and are seeking complementary immune support may benefit from the Blazein activity and beta-glucan-mediated immune activation provided by ABM. The function of NK cells and macrophages is directly relevant to the immune mechanisms involved in cancer surveillance. ABM is used in Japan and Europe as part of integrative oncology treatment protocols alongside chemotherapy and radiation therapy. Consult a MykoTroph therapist before starting ABM as part of your cancer treatment.
People with autoimmune diseases
People with autoimmune diseases such as rheumatoid arthritis, lupus, multiple sclerosis, Hashimoto’s thyroiditis, or inflammatory bowel disease benefit from ABM’s modulatory effect on regulatory T cells and the Th1/Th2 balance. The mechanism is modulatory, not stimulatory. ABM does not uniformly activate the immune system in autoimmune diseases. A MykoTroph therapist can assess suitability and develop a treatment plan tailored to the specific condition.
People with diabetes
People with type 2 diabetes or insulin resistance may benefit from the effects of beta-glucan in ABM on regulating blood sugar levels after meals and improving insulin sensitivity. People who are taking blood sugar-lowering medications should closely monitor their blood sugar levels and consult a MykoTroph therapist when incorporating ABM into their treatment plan.
Patients with allergies and asthma
People with chronic allergies—including seasonal allergies, food intolerances, and asthma—can benefit from ABM’s Th1-promoting effect on the immune system. IgE-mediated reactivity, which underlies allergic reactions, is reduced by this mechanism, which restores balance. Consistent long-term use leads to the strongest immunoregulatory effect.
People with liver disease
People with elevated liver enzyme levels, fatty liver, hepatitis, or those taking medications that cause long-term liver damage may benefit from ABM’s liver-protective effects, which are due to ergothioneine and its support of Kupffer cells. If you have been diagnosed with liver disease or if you are combining ABM with ongoing medication, it is essential to consult a MykoTroph therapist.
People with neurological disorders
People with neurological disorders, early-stage cognitive decline, or high levels of neuroinflammation may benefit from the neuroprotection provided by ergothioneine and the anti-inflammatory effects of ABM via the immune-brain axis. A MykoTroph therapist can integrate ABM into a more comprehensive treatment plan for neurological support.
People with viral and bacterial infections
People with recurrent infections, delayed recovery from acute illnesses, or persistent susceptibility to seasonal illnesses may benefit from the activation of macrophages and NK cells by ABM. This directly supports the primary immune mechanisms against pathogens and reduces the frequency and severity of recurrent infections with long-term use.
People under high oxidative stress
People with high oxidative stress due to chronic stress, intense exercise, environmental toxins, or diseases that cause systemic inflammation benefit from the cellular antioxidant protection provided by ergothioneine in ABM. Ergothioneine accumulates in the tissues most susceptible to oxidative damage and counteracts the problem at the mitochondrial level.
People with cardiovascular risk factors
People with elevated LDL cholesterol, high triglyceride levels, high blood pressure, or a family history of cardiovascular disease may benefit from ABM’s lipid-lowering, vascular endothelial-protective, and blood pressure-regulating properties. Patients taking cardiovascular medications should consult a MykoTroph therapist, as ABM’s effects on lipids and blood pressure may influence medication dosages over time.
How to Take Agaricus Blazei Murrill for Maximum Effect
MykoTroph recommends Agaricus blazei Murrill as an organic whole-mushroom powder in vegan capsules, grown in Germany.
The powder must be extracted from the whole mushroom. Only then is the full spectrum of compounds found in the entire fruiting body preserved. Organic cultivation in accordance with German organic guidelines is considered the gold standard. Mushrooms absorb all kinds of contaminants from their environment. Conventional cultivation carries the risk that pesticide and chemical residues will bind to the beta-glucan fraction and impair its receptor activity. German organic standards are among the strictest.
The mushrooms must be dried gently at temperatures below 40 °C. Higher temperatures destroy important enzymes and polysaccharides that are essential for their health-promoting effects. The grinding process must also be carefully monitored, as it generates heat.
Capsules are preferable to loose powder. Loose powder quickly absorbs moisture and can develop mold, often without anyone noticing. Furthermore, contact with oxygen oxidizes the unsaturated fatty acids and other sensitive compounds in the powder. Capsules protect the entire mushroom powder from these changes and preserve the active ingredients until they are absorbed. Tablets are not recommended, as they require fillers and binders.
Take ABM capsules shortly before a meal with a glass of still water. MykoTherapy treatments are designed to last at least three months. Depending on your health, it may be advisable to continue taking them for longer than three months.
The appropriate dosage depends on your individual health status, your baseline level, and any concurrent treatments or medications you are taking. Have a MykoTroph therapist create a personalized dosing plan for you. Frequently asked questions
Two compounds distinguish Agaricus blazei Murrill from all other medicinal mushrooms. First, blazein: a steroid compound found exclusively in Agaricus blazei Murrill that has been shown to have tumor-inhibiting effects, including the induction of apoptosis and the inhibition of angiogenesis. No other medicinal mushroom contains this compound. Second, the specific branching structure of the beta-1,3/1,6-D-glucan compound in Agaricus blazei murrill, which produces some of the strongest immunomodulatory effects observed in mushroom research.
Yes. In MycoTherapy, ABM is used as a complementary therapy to conventional cancer treatment, not as a substitute. Its immune-activating compounds support the function of NK cells and macrophages. ABM is incorporated into integrative oncology treatments in Japan and Europe. Anyone diagnosed with cancer should consult a MykoTroph therapist before beginning ABM treatment. Dosage, timing, and combination with other medicinal mushrooms must be tailored to the specific type of treatment and the stage of the disease.
This treatment may be appropriate, but it requires careful planning. The immunological effects of ABM are not uniformly stimulatory. In autoimmune diseases, the relevant mechanism is modulatory: ABM supports the activity of regulatory T cells and the restoration of Th1 balance. The appropriate dose, duration, and suitability for the specific autoimmune disease must be assessed on an individual basis. Consult a MykoTroph therapist before beginning treatment.
Cellular effects begin with the very first dose. With regular use, a measurable increase in immune activation typically occurs within two to four weeks. Metabolic effects, including blood sugar regulation and lipid regulation, develop over one to two months. More pronounced effects in complex treatments for autoimmune diseases, as adjunctive cancer therapy, or for protecting the nervous system require a treatment duration of at least three months.
Yes. In MycoTherapy, ABM is often combined with other medicinal mushrooms whose active ingredient profiles complement one another. Reishi contributes to immune regulation and provides adaptogenic support. Butterfly Tramete offers a variety of beta-glucans and supports the gut flora. Cordyceps provides energy and supports the adrenal glands in cases of fatigue and immune deficiency. Hericium is often combined with ABM in neurological treatment protocols. A MykoTroph therapist can develop a dosage plan tailored to your specific health situation.
