What is Lion's Mane Mushroom?
Lion's mane mushroom, also known by its scientific name Hericium erinaceus, is an edible mushroom that has long been used in traditional Chinese medicine. In recent years, lion's mane mushroom has been gaining popularity in the West due to a number of potential health benefits associated with it.
Origin and Appearance
Lion's mane mushroom is native to North America, Europe, and Asia. It gets its name from its unique appearance. The mushroom has long, cascading tendrils that resemble a lion’s mane.
This mushroom grows on both living and dead broadleaf trees and logs, especially maple, beech, oak, birch, walnut, and sycamore. Lion’s mane grows in temperate forests across North America, Europe, Asia and parts of Africa.
Potential Health Benefits
Lion's mane mushroom contains bioactive compounds that may offer a variety of health benefits:
- Supports cognitive function
- Protects against dementia and neurological decline
- Reduces mild symptoms of depression and anxiety
- May help with diabetes management
- May combat inflammation
- May inhibit tumor growth
Let's take a closer look at some of the key potential health benefits of lion's mane mushroom:
Cognitive Function and Neurological Health
Lion's mane mushroom contains two compounds, hericenones and erinacines, which may stimulate nerve growth in the brain and help protect neurons.
Animal studies found lion’s mane mushroom extract improved memory and cognitive function in mice and rats. The mushroom may also help prevent neuronal damage caused by Alzheimer’s disease.
Human studies also show promise. Consuming lion’s mane mushroom or extract has been shown to improve mild cognitive impairment and symptoms of anxiety and depression in humans.
Diabetes Management
Polysaccharides extracted from lion’s mane mushrooms improved blood glucose balance, insulin sensitivity and related symptoms in mice and rats displaying diabetes-like tendencies.
This anti-diabetic activity extends to the treatment and prevention of additional metabolic disorders like obesity.
While human-based research is less robust, some studies indicate similarly protective effects against metabolic disease following lion’s mane supplement ingestion.
Anti-Cancer Potential
Studies indicate that lion’s mane extract has the potential to slow the progression of certain cancers by inhibiting tumor growth.
An extract of lion’s mane mushroom has been shown to slow the growth of liver and colorectal cancer cells in mice, for example.
The exact anti-cancer effects in humans still need to be researched further.
Reducing Inflammation
The lion’s mane mushroom contains amyloid, a carbohydrate, which possesses powerful anti-inflammatory abilities. This includes inhibiting the release of pro-inflammatory molecules in the body.
By limiting inflammation, health may improve across many bodily systems over the short and long term.
How Is It Used?
There are a few ways lion’s mane mushroom is used to promote health:
- Extract supplements - Lion's mane is dried and ground into powder to put in supplements, like capsules or tablets.
- Powder - The mushroom can be finely ground into powder and stirred into smoothies, tea, soup broths and more.
- Whole mushrooms - Fresh or dried lion’s mane mushrooms can be sautéed in olive oil and enjoyed in dishes.
- Tinctures - A lion’s mane tincture featuring an alcohol extract is another supplement format.
Is Lion's Mane Mushroom Safe?
Currently, there are no severe lion’s mane mushroom side effects reported. Mild digestive upset may occur if it is not tolerated well or if you’re new to ingesting fungus.
Of course, consult your doctor before trying lion’s mane mushroom if you are pregnant, breastfeeding, taking medication, or being treated for a health condition.
As with any mushroom, only harvest wild lion’s mane from trusted sources and environments. It’s better to use supplements you can find online or in health food stores for safety and standardization.
How To Grow Lion’s Mane Mushrooms
If you’re up for the challenge, growing your own lion’s mane mushroom at home is possible.
Lion’s mane mushroom cultivation kits are available for home growers. These provide sterilized sawdust spawn bags inoculated with lion’s mane mycelium. Just cut open the bag when the mycelium finishes spreading and maintain the right humidity and airflow conditions.
You can also grow lion’s mane mushrooms from plug spawn blocks or use freshly cut logs in a shady, humid part of your backyard.
Expect the mushroom growth process to take a few weeks to a few months depending on temperatures and care. When harvesting lion’s mane mushrooms, use shears to snip them near the base of the stem.
Final Thoughts
With research continuing to unearth health benefits, lion’s mane mushroom shows therapeutic potential. It appears especially promising for supporting cognitive, nerve and brain health.
Lion’s mane is generally safe to consume and is easy to add to meals or ingest as a supplement. Although more human research is still needed, current findings offer hope that lion’s mane can improve neurological, diabetic, inflammatory and perhaps even cancerous conditions.
