Lion's Mane (Hericium erinaceus)

What is Lion's Mane?

Lion's mane is a medicinal wood-rotting fungus with a characteristic growth pattern that resembles the shaggy mane of a lion.

The fungus prefers temperate forests in North America, Europe, and Asia where it thrives on living oak, beech, or conifer trees.

The medicinal benefit of lions mane primarily involve the nervous system. Modern applications use the mushroom for general cognitive health and as a natural nootropic substance.

This mushroom is also eaten as a delicacy — with a flavor similar to lobster when cooked with butter.

In recent years lion's mane has caught the eye of the nootropic community for its ability to up-regulate nerve growth factor.

How Is Lion's Mane Used?

Lion's mane is mainly used for neurodegenerative disorders like dementia and multiple sclerosis. It's also popular as a nootropic agent for supporting optimal cognitive function long term.

Most of the people using this fungus take it in the form of a powdered capsule or tincture on a daily basis. Like most medicinal mushrooms, the biggest benefit comes from using the herb on a regular basis over long periods of time — rather than short bursts for quick impact of effects.

Traditional Use of Lion’s Mane

Lion’s mane mushrooms have a long history of use in Eastern Asia — including China, Korea, and Japan. Each of these regions used the mushroom for treating neurological disorders, including neurasthenia, and age-related cognitive decline, as well as for general health.

Mycological Information

The Hericiaceae family of fungi are saprophytic (consumes dead wood), yet can be found growing on living trees as well. Many experts believe the mushroom has a mutualistic relationship with the tree for some time — helping it resist disease and infection, but will eventually consume the tree after it dies.

Hericium mushrooms normally grow in cooler, mountainous regions across the globe. It contains a number of species used medicinally and nutritionally.

Hericium spp. has characteristic "tooth" structures on its fruiting body, giving it a hair-like appearance.

Pharmacology & Medical Research

+ Neuroprotective

Lion’s mane offers several different mechanisms to produce its overall neuroprotective benefits:

1. Antioxidant and free-radical scavenging activity [6]
2. Anti-inflammatory activity
3. Nerve-growth factor stimulation (hericium and erinacenes)
4. Reduction of endoplasmic reticulum stress-dependant cell death (dilinoleolyl-phosphatidylethanolamine (DLPE) [7]
5. Attenuation of beta-amyloid-related cognitive decline in animals (dementia model) [8]
6. Enhance mylenation of neurons [9, 10, 11]

In animal studies, lion’s mane has been shown to reduce the severity of damage after a stroke — effectively protecting the sensitive neurons from ischemic damage [6].

Clinical Trials:

Study: Mori et al., 2009 — Improving effects of the mushroom Yamabushitake (Hericium erinaceus) on mild cognitive impairment: a double‐blind placebo‐controlled clinical trial. [5]

This randomized, double-blind, placebo-controlled clinical trial involving 30 Japanese men and women with mil cognitive impairment found that after 16 weeks, the lion’s mane group had significantly increased cognitive scores. These improvements were noted as early as the 8 week checkup, and continued to improve compared to placebo over the rest of the 16-week trial.

The dose of lion’s mane used in this study was 1 gram of dried lion’s mane taken three times per day.

Unfortunately, 4 weeks after the trial concluded, the scores had significantly decreased — indicating that these effects are not permanent and the mushroom needs to be continued to remain effective.

+ Nootropic

A nootropic is a substance that improves cognition without causing harm. There are a lot of nootropic substances that range from herbs like lion’s mane or rhodiola, to synthetic or prescription drugs like Modafinil or Noopept.

Lion’s mane is thought to be a nootropic through its ability to promote nerve-growth factor (NGF) in the brain. NGF is the most potent growth factor for the cholinergic neurons. it influences everything from the proliferation, differentiation, and survival of neuronal cells in the brain [8, 12].

Reductions in NGF has been considered a major implication in conditions such as depression, substance abuse, Alzheimer’s disease, and Huntington’s disease [12].

There have been a lot of studies looking at the role of lion’s mane and nerve growth factor — most of which have concluded that lion’s mane applications directly lead to an increase in NGF. This research has been done both in vivo and in vitro [13, 14, 15, 16].

This effect is very important. We can give peptides like NGF to people to treat these neurodegeneration, but these peptides rarely cross the blood brain barrier [9]. Therefore, finding alternative ways to boost NGF or other peptides in the brain are of the utmost importance in the treatment, prevention, and management of neurodegenerative disorders.

+ Immunomodulation

Like many other medicinal mushrooms, lion’s mane contains a high concentration of polysaccharides with immunomodulatory effects.

A lot of this study has been done in vitro with dendritic immune cells. These cells serve as the antigen-presenting cells that act as central mediators for the immune response as a whole. They’re responsible for a lot of the tolerance formed by the immune system to help maintain homeostasis.

Studies involving lions mane extracts have shown the fungus can stimulate the maturation of dendritic cells, induce dendritic cell activation, and modulate key T-helper (Th1) immune responses [17].

+ Anti-Inflammatory

Lion’s mane has been shown to influence a variety of inflammatory mediators, including:

Induces IL-1β expression through Nf-kB, NF-IL6, and activator protein 1 (AP-1) [18]

Induces iNOS gene expression to increase nitric oxide (NO) production in macrophages

Inhibits toll-like receptor 4 (TLR4)-JNK signalling on macrophages [19]

Phytochemistry of Lion’s Mane Mushrooms

Lion’s mane fruiting body and myclelia contain an exceptionally diverse range of unique bioactive substances — including polysaccharides, meroterpenoids (hericinones), cyathane diterpenoids (erinacines), steroids, alkaloids, and lactones.

The most significant constituents in terms of the mushrooms medicinal action are the hericenones and erinacines. Both of these substances have been shown to stimulate nerve growth factor in the central nervous system. This is thought to be the primary mechanism for which the fungus an improve the health and function of the nervous system.

Clinical Applications Of Lion's Mane:

Lion's mane has many uses, but the most well-known is as a neuroprotective, and nootropic benefits. It's useful for neurodegenerative disorders including multipple sclerosis, Alzheimer's disease, and Parkinson's disease.

Other uses include depression and anxiety, cancer, diabetes, gastrointestinal infection, and fatigue.

Cautions & Safety

Lion’s mane is a culinary mushroom that’s been used for both food and medicine by countless individuals over several hundreds of years. There are no expected short-term or long-term side effects from using the fungus.

Throughout the clinical research there have been no reports of serious side effects from using the fungus — including very high-potency extracts and long-term durations of use.

Caution advised with any blood clotting conditions or medications due to possible agonistic interactions — including haemophilia or other bleeding disorder, thrombocytopenia, or post-surgery. Lion’s mane may interact with blood thinners or anti-platelet medications.

Reishi (Ganoderma lucidum)

What is Reishi?

Reishi is a medicinal forest-grown fungus. It's revered in traditional medical systems across Asia for its powerful immune-enhancing and longevity-promoting benefits.

Medicinal mushrooms are notorious for their complex effects on the immune system — often working in both directions (stimulation and inhibition), depending on what’s needed.

Reishi is no different — it's one of the most important medicinal herbs for longevity and immune health in the world.

This saprophytic (tree-eating) fungus is often used for the prevention and treatment of immune-related illness — including cancer, autoimmunity, infection, inflammation, and allergic reaction.

Reishi is also used for anxiety, depression, insomnia, and as a general adaptogen for overall health and wellbeing.

What is Reishi Used For?

Reishi has the unique ability to act bidirectionally on the immune system — which means it can increase immune activity, and decrease immune activity. It appears it will push the immune system in whatever direction it needs to go. In patients with low immunity or cancer, reishi up-regulates the immune response.

however, in patients with hyperactive immune activity — such as autoimmune disease or allergic reaction — reishi has an opposite effect, toning down the immune response.

This is an effect not well understood to this day, but gives the mushroom an incredibly versatile set of benefits.

Traditionally, reishi is considered a shen tonic — which is used to calm the nerves, ease anxiety, and promote healthy sleep (without being directly sedative).

Most people use reishi as a general health and immune tonic. It’s used by people with known immune-related illness — such as frequent infection, autoimmunity, chronic inflammation, cancer, and more.

Others use the herb as a prophylactic against common infections like colds and flus, or to keep chronic viral infection at bay (such as herpes or shingles).

Traditional Uses of Reishi

The spores are suggested to contain high amounts of jing and considered an elixir of life [1].

Other uses include Hashimoto's disease, in foot baths for gout, altitude sickness prevention, and immune regulation. [1].

+ Ayurveda

A related species — Ganoderma applanatum — has been used extensively in Ayurvedic systems in the pine region of India. Its uses include stopping excessive salivation in the mouth, as a styptic.

+ Other Historical Uses

Reishi has been used medicinally in Asian countries for at least 4000 years and is the most widely depicted mushroom in Japan, Korea, and China, which can be found on temples, tapestries, statues, and paintings.

Reishis rarity and subsequent value made it most accessible to the privileged like emperors and royalty. It has long been associated with longevity and was included in many ancient medical texts for this purpose.

Used to treat liver ailments, lung conditions, kidney disease, nerve pain, hypertension, gastric ulcers, and insomnia. The antler growth pattern is considered very rare and is the most desired for promoting sexual function in both men and women.

Other uses include its use as a means to ward off evil by hanging dried specimens over the door. Similarly, it has been placed on the graves of shamans to protect from evil souls or spirits.

Reishi has been used in nearly every format imaginable including tinctures, teas/decoctions, powdered preparations, brewed into beers and wines, and eaten raw.

Mycological Information

There are about 80 different species of Ganoderma, many of which are used as medicine. The Ganodermataceae contains 8 genera and roughly 300 different species.

Reishi is a saprophyte, meaning it only eats dying or decaying organic matter such as wood. It's mainly found growing on dying trees, stumps, and fallen logs.

Ganoderma spp. is long-lived — releasing approximately 30 billion spores everyday for up to 6 months or a year [1].

Habitat Ecology, & Distribution:

Wild Ganoderma lucidum is rare but is indigenous to forested regions of Asia including Japan, China, and Russia. Other species are found in North America and Europe.

It grows on Elm (Ulmus spp.), alder (Alnus spp.), oak (Quercus spp.), maple (Acer spp.) and some strains on conifers. Other species of Ganoderma such as G. tsugae or G. oregonense grow better and almost exclusively on conifers. G. lucidum, however, prefers hardwoods.

G. lucidum can be found very rarely in the Pacific Northwest, and a similar species (G. curtisii), is seen more commonly in eastern Canada around the great lakes region [1]. This species is actually a yellow form of the red G. lucidum.

Most reishi products on the market are cultivated in a sterile environment on logs or sawdust in large laboratories.

Harvesting Collection, & Preparation:

Both the mycelium, fruiting body, and spores are used medicinally. The red and purple varieties are considered the most valuable. These phenotypes are also thought to be the most potent in their effects [1].

The spores can be either taken raw or can be cracked. This basically involves the germination, then drying of the spores and is suggested to provide stronger medicinal effects after this germination process has taken place.

Another, much more expensive way of ingesting the spores it to run it through a supercritical CO2 extractor. This method creates a product that is roughly equivalent to 20-40 of the raw spore capsules [1].

A mushroom oil can also be extracted from the fruiting body waxes, can be used as is topically, or added to lotions, and salves.

Cosmetically it is useful as a sunscreen due to its radio-protective effects, as well as in anti-aging creams, and to remove warts [1].

As with most hard, polypores, chop the fungus into strips (better when wet or a saw may have to be used), and crumble into small pieces.

Decoct in water, then strain and freeze the leftover mush, doing this will cause the cell walls to burst and allow more constituents to be extracted during the next process. Next, after it has been frozen for 24 hours or so, de-thaw, and mix with 95% alcohol for at least 2 weeks.

In the end, strain, and combine with the decoction made earlier to a standardized amount.

Pharmacology & Medical Research

+ Antibacterial

Ganoderma applanatum is an effective inhibitor of:

• Bacillus cereus
• Cornybacterium diphtheria
• Escherichia coli
• Pseudomonas aeruginosa
• Staphylococcus aureus
• Streptococcus pyogenes

Gram-positive bacteria were more affected than gram-negative [1].

It has been suggested that the polysaccharides in Ganoderma spp. are more antibacterial — while the triterpenoids are more antiviral.

More research is needed to elucidate on this further.

+ Anti-diabetic

Ganoderma has been reported to produce potent lens aldose reductase inhibition, and significant inhibition of serum glucose and sorbitol accumulation in the lens of the eye, red blood cells, and sciatic nerves in diabetic rats (based on earlier studies) [1]. This shows potential as a treatment for diabetic induced retinopathy and other diabetes-related damage in the body.

Has been shown to lower blood sugar levels in hyperglycemic models (fruiting body), and involved the ganoderan B and C [1].

In a study on type 2 diabetics not on insulin, were given reishi extracts, and compared to the placebo control group, were found to have significantly decreased glycosylated hemoglobin (8.4%-7.6%), in as little as 12 weeks. Fasting insulin levels, 2-hour -post-prandial insulin, fasting C-peptide, and post-prandial C-peptide all showed significant improvement in the reishi group [1].

Spores have also shown evidence for anti-diabetic effects [1].

+ Antioxidant

Methanol extracts of G. tsugae were found to be more potent in antioxidant effects that alpha-tocopherol, and exhibited significant inhibition of lipid peroxidation as such.

The antioxidant effects are not considered as reliable as G. lucidum but are very close. It is the phenol content that has been deemed responsible for these effects. [1].

G. tsugae fruiting body extract was shown to increase intracellular glutathione levels, which in turn protect against oxidative damage [1].

+ Antiulcer effects:

Polysaccharides from Ganoderma spp. protects the gastric mucosa by improving PGE2. This backs up some of its uses in the form of tea for treating ulcers.

+ Antiviral

G. lucidum fruiting body extracts have been shown to inhibit HIV, and HPV [1].

Rogers, (2011) reports that Ganaderiol-F, ganodermadiol, ganoderic acid beta, and lucidumol have all been identified as antiviral agents.

G. resinaceum (and most likely G. tsugae, and G. lucidum as well), have been shown to inhibit punta toro, pichinde, and H1N1 [1].

+ Blood Tonic

Reishi been shown to enhance the production of interleukin-1 in vitro, and increase white blood cell and haemoglobin levels in mice [1].

+ Cardiotonic

Reishi has been shown to improve symptoms of coronary heart disease [1].

G. lucidum has been shown to provide anti-cholesterol, anti-diabetic, reduced platelet aggregation, anti atherosclerotic, and antihypotensive effects, which all play a role in the development of cardiovascular disease.

Suggested to produce angiotensin-converting enzyme inhibition through its ganoderic acid B, C2, D, and F [1].

+ Chemoprotective

Has been shown to increase natural killer cell activity of splenocytes by up to 52% [1]

+ Hepatoprotective

The triterpenoids contained in the mycelium of G. tsugae have shown hepatoprotective activity [1].

Ganodereic acid B has shown hepatoprotective effects [1].

+ Immunomodulatory

The polysaccharides from the mycelium were found to be both anti-inflammatories, and immune-stimulating, Rogers, (2011), suggests contradiction from these two effects suggest bi-directional (immunomodulatory) effects on immune response, rather than just stimulating. This appears to be dose-dependent and may be through modulation of cytokine production.

Reishi has been shown to both reduce inflammation and increase immune response — which is contradictory in that an increased immune response should correlate with inflammation. It's has been suggested that G. lucidum produces this apparent modulatory effect through the enteric mucosal pathway. Its effects on the immune system do not appear to be through IgE antibody synthesis, rather through a modulating effect on immunoglobulin levels [1].

+ Sedative

The spores are suggested to produce sedative and hypnotic effects in mice [1].

+ Other

There's some evidence to support the effects of reishi towards bronchitis and other lung disorders . The chemicals suggested to be responsible for these effects are gonoderic acids A, B, C1, and C2 [1].

Phytochemistry

+ Compounds by Anatomy

Fruiting Body

Carbohydrates, amino acids (including adenosine), steroids (ergosterols), protease, lysosomes, lipids, triterpenes, alkaloids, vitamins B2 and C, minerals (zinc, manganese, iron, copper, germanium), beta-glucans (up to 40.6%), [1].

Mycelium

To compare with G. lucidum, ganoderenic acid, and ganoderic acid is found in both [1].

Ganoderma lucidum

Still compiling research.

Clinical Applications Of Reishi:

Reishi is used as a supportive agent for cancer, autoimmune conditions, cardiovascular dysfunctions, respiratory dysfunctions, viral and bacterial infection, and hypertension. It's rarely used on its own, but makes for a great addition to herbal formulations.

Cautions:

Caution advised in combination with ACE inhibitor medications due to potential drug interactions.

Synergy

For altitude sickness: Combines well with rhodiola for this purpose.

It has been suggested that vitamin C helps absorb this mushroom, however, more research is needed to confirm this. Pineapple and ginger may also increase the absorption of reishi constituents.

Graviola (Annona muricata)

What is Graviola?

Graviola is a large tropical tree with a rich history of traditional use for conditions like cancer, parasitic infection, insomnia, and dysentery. Modern use remains very similar, mainly focusing on tension headaches and muscle aches, insomnia, diabetes, cancer, hypertension, and parasitic infection.

Although the entire plant has been used as medicine by various traditional medical systems, the most common form the plant is available in today is as a leaf extract, and raw leaves intended for tea.

Graviola is gaining in popularity outside worldwide as a general health supplement, blood sugar regulator, and anticancer agent. As a result, it's getting easier to find the herb as time goes on. It is likely this tea will become a staple in Western herbal medicine in the coming years.

How Is Graviola Used?

Graviola is mainly used as an adjunctive treatment for cancer, especially leukemia and other haematological cancers, as well as prostate, colon, and breast cancers.

Graviola is also popular as an anti-diabetic herb, and can be used to reduce hypertension, especially in combination with diabetes or metabolic syndrome.

Graviola is a potent anti-parasitic, useful for a wide range of different parasitic species, including worms, protozoa, and bacterial parasites.

Traditional Uses of Graviola

+ South America

Graviola originated from South America and/or the Carribean. All parts of the plant were used as medicine for a wide range of conditions.

The most common use of the plant appears to involve cancer treatment and parasitic infection.

The darkest leaves on the plants were used primarily as a sedative or antispasmodic. They were used to treat insomnia, arthritic pains, colic, dysentery, muscle aches, headaches, and diabetes. The leaves were often placed inside a pillow or bedsheets to improve sleep.

In Brazil, the leaves were made into a tea for treating various liver conditions. The oil of the leaves and unripe fruits were used topically for treating neuralgia, and arthritis.

In Peru, the leaves were used to treat excess catarrh, and the bark and root were used for treating diabetes, insomnia, and muscle aches.

In Guyana, the leaves were used as a heart tonic.

+ Southeast Asia

In Southeast Asia, graviola was an important treatment for malaria. It was made into candies, ice cream, and syrups for treating malaria and other parasites.

Botanical Information

Graviola is a large tree, growing to a height of 10m. It requires high humidity, warm weather, and high annual rainfall in order to thrive. It produces large, edible fruits with an acidic taste (hence the common name soursop).

There are over 130 different genera in the Annonaceae family, and around 2300 different species. The Annona genus itself has about 70 different species. Annona muricata is the most commonly grown worldwide.

Phytochemistry

There are over 100 annonaceous acetogenins in the plant, which are considered to be the primary active constituents of the plant. Structurally these chemicals are derivatives of long chain (C35 or C37) fatty acids. These compounds are cytotoxic against tumour cell lines, and molluscicidal.

Graviola is also rich in alkaloids, saponins, terpenoids, flavonoids, coumarins, lactones, anthraquinones, tannins, cardiac glycosides, phenols, and phytosterols.

Gymnema (Gymnema sylvestre)

What is Gymnema?

Gymnema is known as "the sugar destroyer" because of its unique ability to inhibit our ability to taste sweet foods.

This quality is used to combat sugar cravings in diabetics to control blood sugar levels.

It's been used for thousands of years in India for treating conditions involving "sweet urine." This is a common symptom of diabetes as sugar diffuses into the urinary tract. Old methods of diagnosis involved tasting the urine to identify a sweet taste.

Gymnema offers a variety of unique benefits towards conditions like diabetes, including changes to the pancreatic beta-cells, responsible for releasing insulin into the blood.

Gymnema is also a diuretic, helping to clear glucose from the blood through urine (in combination with plenty of water of course).

Finally, gymnema leaves inhibit the sweet sensation on the taste buds, making food taste bland and dull, which can be used to reduce the cravings for sweet (high sugar) foods responsible for maintaining the pathophysiology of diabetes and metabolic syndromes.

What is Gymnema Used For?

Gymnema is mainly used to treat metabolic conditions like diabetes, PCOS, and metabolic syndrome. It's also used for dental carries, and poor digestion.

+ Mechanisms

• Inreases the number of insulin-secreting beta cells in the pancreas
• Decreases the perception of sweet taste on the taste buds
• Inhibits peripheral utilization of glucose by somatotrophin and corticotrophin.

Botanical Information

Gymnema is a member of the Apocynaceae (dogbane) family of plants.

In the past, gymnema was included in the milkweed (Asclepiadaceae) family — but has since been changed to a subfamily category.

The Apocynaceae family now contains 5 subfamilies (Apocynoideae, Asclepiadoideae, Periplocoideae, Rauvolfioideae, and Secamonoideae).

It contains 5100 species and 366 genera. There are roughly 50 different species of Gymnema — many of which are used interchangeably.

Many plants in the Apocynaceae family are trees preferring tropical environments — except for a handful of species that prefer to grow in deserts.

Clinical Applications Of Gymnema:

Gymnema is mainly used for metabolic conditions including hyperglycemia, hyperinsulinemia, metabolic syndrome, PCOS, hypertriglyceridemia, and both type 1 and type 2 diabetes. Its diuretic and increases the number of pancreatic beta cells.

One of the more unique effects of gymnema is its ability to inhibit sweet flavor. By simply chewing on the leaves, our ability to perceive sweet flavors gradually fades away — helping to prevent excessive sugar intake in habituated individuals.

Cautions:

High saponins may cause gastrointestinal upset, caution advised with high doses.

Caution advised if taking hypoglyemic medication due to agonistic interaction.

+ Contraindications

• Caution advised with hypoglycemic drugs

Iris (Iris versicolor)

What is Iris?

Iris is a misunderstood herb in many circles. It contains a set of constituents that are known to trigger nausea and vomiting — however, somewhat ironically, iris is also considered useful for treating nausea.

This herb has mild laxative qualities — thought to be due to a combination between its potent bitter constituents stimulating the flow of bile from the liver and gallbladder, and an ability to stimulate the parasympathetic nervous system. It's especially active on the liver, where it's used to treat poor digestion, liver dysfunction, and to treat skin conditions.

Other species sometimes used includes Iris caroliniana & Iris virginica.

What is Iris Used For?

Iris is used to treat skin conditions through the liver by improving elimination pathways and preventing excessive elimination and irritation through the skin. It's useful for acne, psoriasis, eczema, and rashes.

Other common uses of iris is for urinary tract infection, hypothyroidism, lymphadenopathy, and menstrual irregularities.

+ Mechanisms

• Thought to stimulate parasympathetic nervous system
• Iridin thought to induce laxative action due to irritating properties on mucus membranes

Iris is native to North America and is common around marshes, streams, and lakes.

The Iridaceae family is named after the irises and refers to the rainbow due to the many colors of iris flowers. This family contains 66 different genera and approximately 2244 different species. Some of the other famous members of this family include Crocus spp. and Gladioli spp.

Clinical Applications of Iris

Iris has recently seen a peak in interest in the past few years, however, is still not a commonly used herb due to the presence of significant side effects. Iris is contraindicated in anything but small doses due to the mucous membrane irritant and nauseating side effects.

In small doses iris is useful for stimulating bile secretion, promoting movement in the bowels, stimulating the pancreas, and treating skin conditions arising from liver congestion.

Cautions:

Some of the constituents in fresh iris root can cause a burning sensation in the mouth and throat along with diarrhea and abdominal burning. It's considered an emetic, and mucus membrane irritant in higher doses. Use cautiously and only in smaller doses.
