Lion’s Mane: Benefits for Inflammation, Memory, and More (2024)

Hericium erinaceus, or the lion’s mane mushroom, is used to protect against dementia, relieve symptoms of depression, promote faster nerve cell recovery, protect against stomach ulcers, reduce inflammation, and support the immune system.It comes in many forms, ranging from teas and tinctures to capsules and powders.

Lion's mane is an edible mushroom from the tooth fungus family that grows on woody tree trunks. It's called lion's mane because it's large and shaggy. It has a long history and is popular in Asian countries due to its numerous nutritional and health benefits.

Lion’s Mane: Health Benefits of a Non-Psychoactive Mushroom

Possible health benefits of lion's mane include:

Protects Against Dementia

Lion’s mane mushroom provides many health benefits, but there are two plant compounds (hericenones and erinacines) in particular that are neuroprotective. Experts say these plant compounds found in lion's mane can generate new brain cells and protect against ​​neurodegeneration associated with Alzheimer’s and Parkinson’s diseases. More research involving humans is necessary to fully determine the potential of lion's mane for neurodegenerative diseases.

Relieves Symptoms of Depression

Experts have suggested lion’s mane mushroom nutrients could serve as a potential alternative treatment for people experiencing depression. One literature review of studies shows many of the studies regarding the use of lion’s mane for depression are conducted on mice, which makes comparison with human mental health challenging.

The same review says clinical studies on humans are limited and small in sample size and have focused on lion's mane's potential for helping with depression symptoms related to menopause. In one case, depression symptoms including sleep issues in people with menopause were reduced after taking lion’s mane 80% mycelium extract and 20% fruiting body extract daily for eight weeks.However, even in human clinical trials, reviewers say the results are limited by a lack of control groups or rigorous study design.

Quickens Nerve Cell Recovery

Lion's mane is said to have regenerative capabilities, meaning its nutrients can help promote faster nerve cell recovery after injury. Experts say lion's mane is actually one of the few medicinal mushrooms out of some 2,000 different types known for its impact on nerve cell growth and health. However, like much of lion's mane research, the information available on the mushroom's health effects is based on animal studies.

Protects Against Stomach Ulcers

Lion's mane has traditionally treated digestive diseases for thousands of years. In Chinese traditional medicine, it is taken specifically for gastrointestinal issues.

Stomach ulcers can occur due to an overgrowth of a certain type of bacteria known as H. pylori. Stomach ulcers can also result from the long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), which damages the stomach's mucous layer.

A 2019 study of mice suggests lion's mane extract can fight ulcers after three weeks of use.

Reduces Inflammation

Across studies, lion's mane consistently shows the potential to reduce inflammation that contributes to or results from chronic disease. One study demonstrates the anti-inflammatory effects of lion's mane on mice with the digestive condition known as ulcerative colitis. Another study of mice suggests the anti-inflammatory effects of lion's mane extract are significant enough to combat liver inflammation from excessive alcohol consumption.

Supports the Immune System

Lion's mane supports the immune system by promoting better gut health. According to animal studies, it works by stimulating the intestinal immune system and regulating gut bacteria. A healthy intestine fights bacteria and other pathogens that may enter through the nose or mouth and cause infection. The other plant compounds in lion's mane, including a range of antioxidants, also promote a healthy immune system.

How to Supplement With Lion’s Mane

You can find fresh and dried lion's mane mushrooms and lion's mane extracts in supplement stores and online. It is often part of a mushroom mix or blend of medicinal mushrooms, including reishi and chaga. There are no official guidelines for lion's mane supplementation.

Describing How Lion’s Mane Makes You Feel

Lion's mane medicinal mushroom is not psychoactive, so it does not have any intoxicating effects. However, lion's mane is marketed for its potential to increase focus and is associated with reduced feelings of depression. Again, more rigorous research in humans is necessary to determine its full effects.

Possible Side Effects of Lion’s Mane Mushroom
