Introduction
Mushrooms are delicate, beautiful and provided humans with one of the first antibiotics,
penicillin. Some are toxic, and most are consumable. Yet, they are wonderful in the way that
they have their kingdom. They are neither plant nor animal they are entirely different beings.
The whole body of the mushroom, together with fruit (mushroom) and root (mycelium), is
called fungi. So, yes, all mushrooms are essentially fungi residing in their distinct class. Fungi
emerged as separate unicellular organisms in the Precambrian period (from 4.6 billion to 541
million years ago)[1]. So, mushrooms are distant relatives of humans in some ways. How-
ever, they continued their distinct journey of evolution in the Cambrian period.
Humans have consumed mushrooms since they were hunters and gatherers. They
learned about their nourishing properties, realized their medicinal value. People also knew
that some could be used for recreation, while other mushrooms are toxic. Despite such an
old relationship with mushrooms, we are just starting to explore their health benefits fully. In
fact, the situation is so absurd that experts are even unsure of how many species of fungi are
there in the world. Though estimates vary, but researchers think that there are few million
species of fungi. It also means that there are few thousand types of edible and medicinal
mushrooms that are widely used[2]. This article explores one such mushroom that is both
edible and has many health effects. It is nutritious, and can be source of remedies.
Lion’s Mane, a mushroom of many names
Lion’s Mane (also called “bearded tooth”) grows in most parts of the Northern Hemi-
sphere, except in tropical or arctic regions. Thus, it has a different name in each language. It
is commonly called Lion’s Mane due to its appearance. It is called Hericium Erinaceus in
Latin. “Shishigashira” or “Houtou” in China, and the Japanese call it “Yamabushitake”[3].

Although it is present in most of Europe, it is among the rare mushrooms in the wilder-
ness. It is more common in North America, China, and Japan. It has a long history of use in
traditional medicine in China. China is also among the leading growers of mushrooms glob-
ally[4].
Those looking to find these fungi in a natural environment should be careful. It has a
protected status in many European nations. Its picking is prohibited in England and Wales[5].
Fungi can be big and small
All fungi are made up of a thread-like filament called hyphae. However, these hyphae
combine in different ways to produce so many different fungi. Fungi are further divided into
lower fungi (smaller in size) and higher fungi (larger in size). Higher fungi can grow in large
as their filament or hyphae are divided into multiple compartments with the help of a wall-
like structure called septa[1].
Lion’s Mane is a higher fungus or macro-fungi. There are known 14000 species of higher
fungi, and out of them, 350 are consumed by humans[6].
Lion’s Mane grows mainly on dead and decaying trees
Experts would call it a saprophyte, a kind of mushroom that grows on dead and decaying
trees. However, in rare cases, it may be parasitic and grow on living trees[7]. It mostly grows
on dying deciduous trees. In some countries like China, people also cultivate it.
It propagates in nature through spores. Its spores are pretty resistant to various climatic
conditions and can survive for up to 7 years.
It appears to love warmth, but not heat. It grows pretty well in temperatures of 25 to
30°C. It may also grow well in lower temperatures like 20°C, but not in freezing conditions.
Its sporulation stops at temperatures between 31-33°C. It explains why it is mainly found in
Europe in later summer or Autumn. But, it cannot grow in tropical or sub-tropical regions.
Moreover, it does not appear to like very high humidity[7].
Lion’s mane constituents
Mushrooms are the best example of food as a medicine. Various varieties of mushrooms
are consumed as a food, including Lion’s Mane. However, people are significantly more in-
terested in its various biologically active compounds as they are responsible for its numerous
health benefits[7–9].
Composition of Lion’s Mane:
20-22% proteins
57-67% carbohydrates
2.8-3.5% fats
Numerous vitamins (like tocopherols) and minerals (trace elements)
Biologically active compounds
Lion’s Mane is definitely quite nutritious and can be an excellent source of proteins for
vegans. However, people are more interested in the content of biologically active compounds
that confer health benefits.
Most of the compounds responsible for health benefits are polysaccharides (complex
carbs) and phenolic compounds. Researchers are particularly interested in polysaccharides
other than glucose: ribose, arabinose, xylose, galactose, and mannose. Polysaccharides like

xylans, galactoxyloglucans, heteroxyloglucans, glucoxylans, erinacines, and hericenones have
numerous health benefits. However, it is vital to understand that this list is not comprehen-
sive, as researchers have identified hundreds of bio-active compounds[7,9,10].
Some bioactive compounds and their action[7]:

Lion’s mane health benefits
Lion’s mane extract is often used as a health supplement. Researchers are studying its
numerous health benefits. It is especially regarded to be good for nerve health. However, it is
worth understanding that health supplements cannot claim to diagnose or treat disease con-
ditions.
Brain health/Nootropic/Memory support
Neurodegenerative disorders like dementia are now a significant health threat in the UK.
A healthy lifestyle may lower dementia’s risk[11]. Adding Lion’s Mane to the diet may have
certain benefits. Experimental studies suggest synergistic interaction between Lion’s mane
extract and nerve growth factor (NGF). Lion’s many also appear to help with memory. One
of the systemic reviews found that mushroom extracts like that of Lion’s Mane have a positive
impact on cognition[12–15].
In practice, it means that Lion’s Mane is good for brain health. Its regular consumption
may be one of the ways of lowering cognitive decline. However, it is not a treatment for brain
diseases.
Accelerate recovery from nerve injury
Lion’s Mane is also proposed to be good for nerve health. Peripheral nerves may get
damaged due to physical injury, toxins, anticancer treatment, or more commonly, diabetes. In
experimental studies, Lion’s mane extract appears to promote nerve recovery and growth.
Thus, it may have a role as a health supplement in preventing neuropathies[13,16,17].
It helps counter mild anxiety and depression
Chronic ingestion of Lion’s mane extract promotes nerve growth and modulates the
activity of certain neurohormones. Thus, it may exert a mood-stabilizing effect, help prevent
anxiety, lower the risk of depression. It may help on regular use for 4 weeks or more. Thus,
it may be used as one of the ways of preventing mood disorders. However, it should not be
used as a monotherapy for the treatment of severe mood disorders[18–20].

Gastric health
Traditional Chinese medicine regards Lion’s Mane as good for gastric health. Modern
experimental studies show that it may help prevent damage to gastric cells caused by ethanol.
It also suppresses the activity of H. Pylori, a bacteria frequently responsible for gastric ulcers.
Thus, regular use of Lion’s Mane may help prevent gastric issues[21–23].
Heart health and cholesterol control
Mushrooms are naturally low in fats and do not contribute to hypercholesteremia. Ad-
ditionally, certain mushrooms like Lion’s Mane have compounds that suppress lipid oxidation
and exert an antihyperlipidemic effect. Thus, Lion’s Mane is regarded as good for cardiovas-
cular health[24,25].
Lower blood sugar levels
Mushrooms can be safely consumed by those living with diabetes, as they are low in
glycemic index. Additionally, some mushrooms like Lion’s Mane contain compounds that
may help lower the risk of metabolic disorders. For example, lion’s Mane appears to exert an
inhibitory effect on α-amylase and α-glucosidase, thus helping keep blood glucose levels in
check[26,27].
Cancer prevention
A balanced diet and the right lifestyle choices may lower cancer risk. Polysaccharides and
aromatic compounds in Lion’s Mane show anticancer properties in lab studies. Researchers
have identified numerous mechanisms of action. Lion’s mane extract may suppress the
growth of various cancer cells like lung cancer, breast cancer. Researchers are exploring its
role as an adjuvant in cancer management[28–30].
Potential Immunity enhancer
Polysaccharides, hericirine, polyphenols, and other compounds in Lion’s Mane help sup-
press inflammation, exert an antioxidant effect, and modulate immune responses. Thus, its
prolonged use may help support the immune system[31–33].
Safety and toxicity
Lion’s Mane is relatively safe for prolonged use. Quite like other herbal extracts, it may
sporadically cause gastrointestinal issues or allergies. Toxicological studies could not identify
any severe side effects of the mushroom and concluded it safe for prolonged use[34]. How-
ever, there is still a need for more studies regarding its safety. Like most mushrooms, data is
limited. Nevertheless, most preliminary data is highly encouraging.
Conclusion
In conclusion, Lion's Mane, a mushroom known by many names across different re-
gions, holds a special place in the world of fungi. Its unique appearance and widespread dis-
tribution, especially in North America, China, and Japan, have earned it recognition not only
for its culinary uses but also for its potential health benefits. As a member of the higher fungi
category, Lion's Mane is just one among thousands of fungal species. Yet, it stands out due
to its remarkable constituents, including proteins, carbohydrates, fats, vitamins, minerals, and
a plethora of biologically active compounds. These compounds, notably polysaccharides and
phenolic compounds, have garnered significant attention for their potential health-promoting
effects.
Lion's Mane offers a range of health benefits, from supporting brain health and memory
to aiding in nerve recovery and growth. It may also contribute to mood stabilization, gastric
health, heart health, cholesterol control, and blood sugar regulation. Moreover, ongoing re-
search suggests its potential role in cancer prevention and immunity enhancement. While Li-
on's Mane extract is commonly used as a health supplement, it's important to emphasize that
it cannot replace medical treatments for diseases. It should be seen as a complementary dietary
addition to promote overall well-being.

Fortunately, Lion's Mane is generally considered safe for extended consumption, with
few reported side effects. Like any dietary supplement, some individuals may experience mild
gastrointestinal issues or allergies, but toxicological studies have not revealed any significant
concerns. Intriguing and versatile, Lion's Mane continues to captivate researchers and health
enthusiasts alike, offering a promising avenue for natural health support. As our understand-
ing of this remarkable mushroom deepens, it may become an even more valuable addition to
our quest for improved well-being and longevity.

Macrofungi production and economic value have been increasing globally. The demand for macrofungi has expanded rapidly owing to their popularity among consumers, pleasant taste, and unique flavors. The presence of high quality proteins, polysaccharides, unsaturated fatty acids, minerals, triterpene sterols, and secondary metabolites makes macrofungi an important commodity. Macrofungi are well known for their ability to protect from or cure various health problems, such as immunodeficiency, cancer, inflammation, hypertension, hyperlipidemia, hypercholesterolemia, and obesity. Many studies have demonstrated their medicinal properties, supported by both in vivo and in vitro experimental studies, as well as clinical trials. Numerous bioactive compounds isolated from mushrooms, such as polysaccharides, proteins, fats, phenolic compounds, and vitamins, possess strong bioactivities. Consequently, they can be considered as an important source of nutraceuticals. Numerous edible mushrooms have been studied for their bioactivities, but only a few species have made it to the market. Many species remain to be explored. The converging trends and popularity of eastern herbal medicines, natural/organic food product preference, gut-healthy products, and positive outlook towards sports nutrition are supporting the growth in the medicinal mushroom market. The consumption of medicinal mushrooms as functional food or dietary supplement is expected to markedly increase in the future. The global medicinal mushroom market size is projected to increase by USD 13.88 billion from 2018 to 2022. The global market values of promising bioactive compounds, such as lentinan and lovastatin, are also expected to rise. With such a market growth, mushroom nutraceuticals hold to be very promising in the years to come.

Depression is a common and severe neuropsychiatric disorder that is one of the leading causes of global disease burden. Although various anti-depressants are currently available, their efficacies are barely adequate and many have side effects. Hericium erinaceus, also known as Lion’s mane mushroom, has been shown to have various health benefits, including antioxidative, antidiabetic, anticancer, anti-inflammatory, antimicrobial, antihyperglycemic, and hypolipidemic effects. It has been used to treat cognitive impairment, Parkinson’s disease, and Alzheimer’s disease. Bioactive compounds extracted from the mycelia and fruiting bodies of H. erinaceus have been found to promote the expression of neurotrophic factors that are associated with cell proliferation such as nerve growth factors. Although antidepressant effects of H. erinaceus have not been validated and compared to the conventional antidepressants, based on the neurotrophic and neurogenic pathophysiology of depression, H. erinaceus may be a potential alternative medicine for the treatment of depression. This article critically reviews the current literature on the potential benefits of H. erinaceus as a treatment for depressive disorder as well as its mechanisms underlying the antidepressant-like activities.

Objectives: A systematic review was undertaken of the evidence on the use of Hericium erinaceus (Reishi), Ganoderma lucidum (Lion's Mane), Ophiocordyceps sinensis (Cordyceps) and Cordyceps militaris (Cordyceps), dietary supplementation on cognitive impairment outcomes. Methods: Relevant articles were identified in major databases (PubMed, Embase, Web of Science, and SCOPUS). Key search words were Hericium erinaceus, Ganoderma lucidum, Ophiocordyceps sinensis, Lion's mane, Reishi, Cordyceps, cognitive, memory, dementia, Alzheimer's. Included studies were peer-reviewed in-vivo articles published in English before January 2019, with cognitive outcomes. Results: Twenty-five (25) of 194 studies met the inclusion criteria: eight (8) studies on lion's mane mushroom, seven (7) studies on reishi mushroom and ten (10) studies on cordyceps mushroom. Three (3) randomized-controlled trials were included in this review. Studies varied by animals used, preparation of supplement, dosage and duration of supplementation, and cognitive outcomes. Twenty-two (22) animal studies found positive results (P < 0.05) on at least one of the doses tested for at least one cognitive impairment outcome. Of the human trials, two (2) studies found positive results (P < 0.05) on at least one of the cognitive assessments. Conclusions: Despite heterogeneous study design, the results of this review suggest that dietary supplementation with lion's mane, reishi and cordyceps mushrooms may have a beneficial effect on cognitive impairment. Further clinical research studies are needed to demonstrate the potential medicinal benefits of dietary mushroom supplementation in humans with cognitive impairments. Funding sources: No external funding.

Versatile biological activities of Hericium erinaceus (HE) have been reported in many brain diseases. However, roles of HE in major psychiatric disorders such as depression and anxiety remain to be investigated. Therefore, we evaluated whether HE could reduce anxiety and depressive behaviors in the adult mouse and its underlying mechanisms. Male C57BL/6 mice were administered HE (20 or 60 mg/kg, p.o.) or saline once a day for 4 weeks. Open field and tail suspension tests were performed 30 min after the last administration of HE, followed by forced swim test 2 days later. We found that chronic administration of HE showed anxiolytic and antidepressant-like effects. To elucidate possible mechanisms, proliferative activity of the hippocampal progenitor cells was assessed by immunohistochemistry of proliferating cell nuclear antigen (PCNA) and Ki67. Moreover, to evaluate neuronal survival in the dentate gyrus, 5-bromo-2'-deoxyuridine (BrdU) (120 mg/kg, i.p.) was given at the first day of HE administration, followed by isolation of the brains 4 weeks later. HE (60 mg/kg) increased the number of PCNA- and Ki67-positive cells in the subgranular zone of the hippocampus, indicating increased proliferation of hippocampal progenitors. In addition, BrdU- and BrdU/NeuN-positive cells in the dentate gyrus were significantly increased when treated with HE (60 mg/kg) compared with the saline-treated group, demonstrating enhanced neurogenesis by HE treatment. Taken together, the results indicate that chronic HE administration can exert anxiolytic and antidepressant-like effects, possibly by enhancing adult hippocampal neurogenesis.

More than 2000 species of edible and/or medicinal mushrooms have been identified to date, many of which are widely consumed, stimulating much research on their health-promoting properties. These properties are associated with bioactive compounds produced by the mushrooms, including polysaccharides. Although β-glucans (homopolysaccharides) are believed to be the major bioactive polysaccharides of mushrooms, other types of mushroom polysaccharides (heteropolysaccharides) also possess biological properties. Here we survey the chemistry of such health-promoting polysaccharides and their reported antiobesity and antidiabetic properties as well as selected anticarcinogenic, antimicrobial, and antiviral effects that demonstrate their multiple health-promoting potential. The associated antioxidative, anti-inflammatory, and immunomodulating activities in fat cells, rodents, and humans are also discussed. The mechanisms of action involve the gut microbiota, meaning the polysaccharides act as prebiotics in the digestive system. Also covered here are the nutritional, functional food, clinical, and epidemiological studies designed to assess the health-promoting properties of polysaccharides, individually and as blended mixtures, against obesity, diabetes, cancer, and infectious diseases, and suggestions for further research. The collated information and suggested research needs might guide further studies needed for a better understanding of the health-promoting properties of mushroom polysaccharides and enhance their use to help prevent and treat human chronic diseases.

To obtain activated fractions, the ethanol extract (EE) of Hericium erinaceus was fractionated to get petroleum ether fraction (PEF), chloroform fraction (CF), ethyl acetate fraction (EAF) and n-butanol fraction (NF). Total phenol content (TPC) and total flavonoid content (TFC) in the fractions were determined, and the phenolic compounds were characterized and quantitated using liquid chromatography-electrospray ionization-mass spectrometry. Meanwhile, in vitro antioxidant and antihyperglycemic activities of extracts were evaluated respectively based on their 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging abilities as well as α-amylase and α-glucosidase inhibitory abilities. Finally, the inhibition modes of extracts on α-amylase and α-glucosidase were detected by kinetic assay. The results showed that TPC, TFC, and the content of phenolic compounds in the extracts were different. EAF contained the highest contents of both TPC and TFC and exhibited strongest inhibitory effects on α-amylase and α-glucosidase, with half maximal inhibitory concentration (IC50) values of 0.47 ± 0.02 and 0.63 ± 0.01 mg/mL, respectively. However, CF showed the highest scavenging abilities on DPPH and ABTS radicals, with IC50 values of 2.30 ± 0.12 and 1.72 ± 0.06 mg/mL, respectively. Correlation analysis showed that the high antihyperglycemic ability of EAF may be related to ferulic acid, whereas cinnamic acid may be responsible for the high antioxidant ability of CF. Furthermore, all fractions were found to exert inhibition on α-amylase and α-glucosidase in mixed-type and competitive manners, respectively. Overall, these results suggest that H. erinaceus has a potential effect on antihyperglycemic and antioxidant activity.

Hericium erinaceus (Hericiaceae, Agaricomycetes) is an edible and medicinal mushroom shown to exhibit anticancer effects in various cancers. However, little is known about the effects of H. erinaceus on breast cancer. Here, we aimed to examine the anticancer effects of H. erinaceus water extract on cell viability, apoptosis, and cell cycle distri-bution in MCF-7 estrogen receptor–positive (ER⁺) human breast adenocarcinoma cells. We also investigated the possible synergistic interactions between the extract and a known ER antagonist, tamoxifen. Finally, we performed a whole ge-nome transcriptome analysis to investigate the molecular mechanisms underlying the tumoricidal effect of H. erinaceus on breast cancer cells. H. erinaceus water extract was capable of inhibiting cell viability of MCF-7 breast cancer cells in a time-and dose-dependent manner. Treatment with the extract significantly induced apoptosis and G1 cell cycle arrest in cells, consistent with the results of the cell viability analysis. H. erinaceus water extract showed strong synergism with tamoxifen in inhibiting cell viability of MCF-7 cells. The treatment altered the expression of a total of 362 transcripts, including c-Fos, FBJ murine osteosarcoma viral oncogene homolog (FOS), eukaryotic translation initiation factor 1 (EIF1), HES family basic helix-loop-helix transcription factor 1 (HES1), early growth response 2 (EGR2), cyclin L1 (CCNL1), EGR3, Kelch-like family member 24 (KLHL24), and inhibitor of DNA binding 2 (ID2). Results of Gene On-tology enrichment analysis suggest that these genes are mainly associated with transcriptional regulation processes. The cancer signaling pathways that were significantly enriched for differentially expressed genes in response to H. erinaceus treatment were tumor protein P53, Janus kinase–signal transducer and activator of transcription JAK-STAT, transforming growth factor-β, and mitogen-activated protein kinase. Overall, our results provided in vitro evidence that H. erinaceus water extract could be a potent candidate for the treatment of ER⁺ breast cancer.

Ethnopharmacological relevance Hericium erinaceus, commonly called lion’s mane mushroom, is an edible and medicinal mushroom that has been traditionally used for the treatment of metabolic disorders, gastrointestinal diseases and memory impairment. In this study, potential anti-hyperglycemic constituents were identified to support the traditional usage of H. erinaceus. Materials and methods The components of H. erinaceus were purified using various column chromatography techniques. The structure of the separated compounds was determined based on spectroscopic data analysis, i.e., 1D and 2D NMR analysis. The anti-hyperglycemic activity of the isolated compounds was evaluated by measuring the inhibitory effects on α-glucosidase activity. Molecular docking analysis was also conducted for elucidation of α-glucosidase inhibitory activity of isolated compounds. Results Ten compounds including four new compounds, erinacenols A-D (1-4), were isolated from the fruiting bodies of H. erinaceus. Investigation of the anti-hyperglycemic effect of isolated compounds demonstrated that erinacenol D (4), 4-[3',7'–dimethyl-2',6'-octadienyl]-2-formyl-3-hydroxy-5-methyoxybenzylalcohol (6), hericene A (7), hericene D (8) and hericenone D (9) strongly inhibited α-glucosidase activity with IC50 values of < 20 μM. The structure activity relationship suggested the importance of long side chain for α-glucosidase inhibitory activity. Further analysis by molecular docking demonstrated the interaction of α-glucosidase and isolated compounds, which supported the inhibitory activity of α-glucosidase. Conclusion Our present study demonstrated the beneficial effect of H. erinaceus by characterization of α-glucosidase inhibitory compounds, including four new compounds. This approach can be valuable support for the traditional use of H. erinaceus for the treatment of diabetes and metabolic diseases, which needs to be clarified by further in-vivo study.

Natural products are sources for exploratory development of new agents to combat the gastric pathogen Helicobacter pylori. Some edible fungi, such as the lion’s mane mushroom, have been used for several thousand years to treat digestive diseases. Ethanol-based extractions to prepare Hericium erinaceus extracts were tested for growth inhibition ability of six different H. pylori strains at an extract concentration that did not inhibit Escherichia coli growth, and further for dose-dependent antibactericidal capacity on H. pylori. H. erinaceus extract exhibited similar growth inhibitory effects on all H. pylori strains tested, with a minimum inhibitory concentration of about 2 mg/mL. H. pylori survival in phosphate-buffered saline (PBS) was decreased 3 logs by 2 mg/mL extract addition. H. erinaceus extract inhibited H. pylori adhesion capacity to human gastric epithelial cell line (ATCC CRL-1739) (AGS), even when H. erinaceus extract was added at a concentration that affected neither H. pylori nor AGS viability. Interleukin-8 (IL-8, representing an immune response factor) in supernatants from AGS and 8-oxo-guanine (8-oxoG, a marker for oxidative DNA damage among the total host cell DNA) were measured from AGS cells exposed to H. erinaceus extract before H. pylori addition. The subsequent H. pylori-mediated immune response (IL-8 production) was significantly (P < 0.01) decreased by H. erinaceus extract; at 1.0 mg/mL extract addition, IL-8 expression returned to nearly background level (no H. pylori added). H. pylori infection of AGS caused a 3-fold increase in host 8-oxoG, but this increase was abolished by including 2 mg/mL H. erinaceus extract. Mouse colonization assays of C57BL mice were performed on homogenized stomachs 3 weeks after inoculating H. pylori into the animals; mice receiving the H. erinaceus extract had a mean H. pylori load of 6 × 10⁴ CFU/g of stomach, about 1 log lower than the control (no extract) animals.
