What is Lion's Mane Mushroom?

Lion's mane mushroom, also known by its scientific name Hericium erinaceus, is an edible white rot fungus found predominantly in North America, Europe and Asia. It belongs to the tooth fungus group, characterized by downward-facing spines resembling small icicles or teeth. Unlike other mushrooms that grow in soil, lion's mane mushroom grows on both living and dead broadleaf trees.

Other common names for lion's mane mushroom include bearded tooth mushroom, bearded hedgehog mushroom, bearded tooth fungus and pom pom mushroom. In Japan, it is known as yamabushitake which means "mountain priest mushroom". The Chinese call it hedgehog mushroom or hou tou gu.

Lion's mane mushroom can be identified by its unique, cascading white icicle-like spines. The fruiting body is typically 10-20cm across and turns yellow to brown in maturity. It has a round, globe-shaped appearance during early growth and becomes wavy, folded and ruffled as it grows and matures.

Unlike most other mushrooms, lion's mane has no cap or stem. Its flesh is white, with a texture that is initially firm and chewy when young, but becomes soft and stringy-fibrous as it ages. When cooked, it has a crab-like, lobster-like flavor and texture.

Origin and Cultivation

Lion's mane mushroom grows wild in Asia, Europe and North America. In the wild, it is a saprophyte mushroom that feeds on dead and dying hardwood trees and logs, helping to decompose decaying wood.

Over the past decade, lion's mane mushroom has been commercially cultivated across many regions around the world to meet increasing demand. China is currently the largest producer, supplying lion's mane mushroom and its extracts globally.

To cultivate lion's mane mushroom commercially, sterilized sawdust, straw or wood chips are inoculated with lion's mane mycelium. The mushroom offspring (fruiting bodies) grow from nutrient-rich blocks or plastic bags under controlled environmental conditions.

Lion's mane can also be grown at home with mushroom growing kits containing lion's mane mycelium in sawdust or plug spawn. Kits are available from various mushroom suppliers online. Lion's mane kits require humidity and adequate air exchange to fruit successfully.

Lion's Mane Health Benefits

Modern scientific research has confirmed several long-held traditional beliefs about the medicinal properties of lion's mane mushroom. Some of its major scientifically studied health benefits include:

1. Supports Brain Health and Memory

Lion's mane mushroom contains two unique classes of active compounds that have beneficial effects on brain cells (neurons) - hericenones and erinacines. Hericenones readily cross the blood-brain barrier and stimulate the production of nerve growth factor (NGF), a protein vital for maintaining neuron health.

Erinacines, found specifically in lion's mane, also increase NGF levels in the brain and peripheral nervous system. NGF plays an important role in maintaining cognition, memory and brain function as we age. By boosting NGF levels, lion's mane helps support overall brain health and has been shown to reduce mild cognitive impairment in older adults.

Studies also found lion's mane may help regenerate neurons in the brain and neuropathic damage in the nervous system caused by injury or toxicity.

2. May Help Reduce Anxiety and Depression

Up to one-third of people taking lion's mane in studies have reported reductions in feelings of depression and anxiety. This is thought to be linked to its ability to stimulate new neuron growth in the hippocampus, a region of the brain involved in processing memories and emotional responses.

Lion's mane also contains the compound amycenone, which has anti-anxiety effects in mice studies. More human studies are needed, but lion's mane shows promise as a potential natural remedy for managing anxiety, depression and related mood disorders.

3. Protects Against Dementia and Alzheimer's

Some promising animal studies indicate lion's mane extract may help protect against dementia and Alzheimer's disease - a degenerative brain disease characterized by progressive loss of cognition, memory and motor control.

Lion's mane has been shown to reduce the buildup of beta-amyloid plaques in the brain, a hallmark of Alzheimer's disease. It also helps prevent neuronal damage caused by amyloid beta peptides while restoring neuronal health and function.

While human studies are still limited, daily lion's mane supplementation appears to have potential to slow the progression of mild cognitive impairment and early-stage dementia in vulnerable individuals.

4. Reduces Inflammation and Oxidative Stress

Chronic inflammation and oxidative stress are involved in many modern diseases, including cancer, heart disease, diabetes and autoimmune disorders. Lion's mane extract has strong anti-inflammatory and antioxidant effects that may help protect against various health issues related to chronic inflammation.

Specific antioxidant compounds like hericenones in lion's mane help reduce inflammation while enhancing antioxidant activity in the body. Lion's mane may also stimulate the production of Nrf2, the body's natural antioxidant defense system.

5. Supports Heart Health

Heart disease remains a leading cause of death and disability worldwide. Research suggests lion's mane extract can potentially support heart health and help reduce cardiovascular disease risk in various ways.

Studies show lion's mane can inhibit a key enzyme called angiotensin-converting enzyme (or ACE). ACE causes high blood pressure, so blocking it helps lower blood pressure and reduce hypertension risk.

The extract also limits the aggregation of platelets in the bloodstream, reducing the risk of dangerous blood clots that can lead to heart attack and stroke. Thanks to these protective mechanisms, lion's mane shows potential in the prevention of heart disease and support of overall cardiovascular health.

6. Provides Neuroprotective Effects

The nervous system can be damaged by injuries like strokes or spinal cord damage as well as certain neurodegenerative diseases, chemotherapy drugs and environmental toxins. Early research suggests lion's mane extract may help protect neurons and stimulate neuronal regrowth following various types of nervous system damage.

Studies found lion's mane promoted faster recovery following nervous system injuries. It also reduced the severity of neuropathy caused by chemotherapy and provided neuroprotective effects from the pesticide paraquat, indicating potential to mitigate environmental causes of Parkinson's disease.

7. May Combat Cancer

Lion's mane mushroom contains a number of bioactive polysaccharides and other compounds that have been shown to inhibit the growth and proliferation of various cancer cells. Extracts suppress the growth of cancerous tumors in the stomach, lungs, skin, colon, cervix, mouth and ovaries in laboratory studies.

The mushroom also induces cancer cell apoptosis (self-destruction) and enhances the immune system activity against cancer cells. While human studies are still needed, lion's mane shows strong potential as a supportive remedy for cancer patients undergoing conventional treatments.

8. Reduces Symptoms of Depression and Anxiety

Up to one-third of people taking lion's mane in studies have reported reductions in feelings of depression and anxiety. This is thought to be linked to its ability to stimulate new neuron growth in the hippocampus, a region of the brain involved in processing memories and emotional responses.

Lion's mane also contains the compound amycenone, which has anti-anxiety effects in mice studies. More human studies are needed, but lion's mane shows promise as a potential natural remedy for managing anxiety, depression and related mood disorders.

9. Improves Digestive Health

Traditional medicinal uses of lion's mane mushroom often focused on gastrointestinal health and digestion. Modern research has now identified the bioactive compounds behind its digestive benefits.

Polysaccharides from lion's mane mushroom stimulate the growth of beneficial Bifidobacteria in the gut, helping rebalance the microbiota. This improves digestion, reduces gastric ulcers, and protects the stomach lining from damage caused by non-steroidal anti-inflammatory drugs like aspirin.

Lion's mane extracts also reduced inflammation in colon cells and mitigated inflammatory bowel disease in mice studies. More research is underway, but it shows promise for treating stomach and digestive issues.

10. Protects the Liver

The liver performs many vital metabolic functions and is vulnerable to various toxins, fatty buildup and diseases like hepatitis. Lion's mane extract provides hepatoprotective effects, protecting liver cells from damage in several ways.

It reduces inflammation, scarring and fat accumulation in the liver while limiting the death of liver cells. Lion's mane may also inhibit the growth of hepatitis B virus cells and reduce the side effects of liver cancer treatments like chemotherapy.

Other Potential Benefits

Some early studies suggest lion's mane may also provide benefits for:

• Diabetes - Helps regulate blood glucose and insulin levels.
• MRSA - Inhibits the growth of antibiotic-resistant Staphylococcus aureus bacteria.
• Wound healing - Stimulates quicker healing of skin wounds.
• Women's health issues - Relieves menopausal symptoms and endometriosis pain.
• Eye health - Protects retinal cells and vision in studies on eye diseases.

More human research is needed to confirm effects in these areas. But the results so far indicate lion's mane mushroom may prove useful in managing various other health conditions.
