What are Lion’s Mane Mushrooms?

Hericium erinaceus is the scientific name for an edible mushroom known by many common names (bearded tooth fungus, chicken of the woods, monkey head mushroom, the bearded hedgehog), but most people refer to it as lion’s mane. Often referred to as one of the healthiest mushrooms in the world, Hericium erinaceus provides an abundance of benefits for overall mental and physical health.

What are the Medicinal Benefits of Lion’s Mane?

Research on the potential benefits of the lion’s mane mushroom indicates this fungus has nerve regenerating potential, as it aids in the production of nerve growth factor proteins. It appears to ease the symptoms of dementia, lessen oxidative stress, as well as improve brain function and neuronal health. 

Some of the beneficial effects of lion’s mane include:

  • reduces symptoms of ADHD, anxiety, and depressive disorders
  • reduces inflammation and oxidation
  • improves overall brain health and cognitive functioning, including learning and memory
  • reduces the risk of heart disease and blood clots
  • promotes neurite outgrowth
  • improves mental clarity and protects against mild cognitive impairments and Alzheimer’s disease
  • lowers blood sugar levels and aids in diabetes treatment
  • encourages apoptosis (cell death) of cancer cells, and has the potential to fight cancer
  • improves digestive health and prevents stomach ulcers
  • boosts the immune system and improves immune function
  • has neuroprotective properties and reduces nerve damage in neurodegenerative autoimmune disorders, such as Parkinson’s disease

What are the Side Effects of Lion's Mane?

Although there’s no research on the side effects of lion’s mane mushroom extract, the centuries of lion’s mane use in traditional Chinese medicine and cooking suggest that there are no side effects to regular lion’s mane use.

However, if you want to err on the side of caution, talk to a medical professional before you start taking lion’s mane mushroom supplements or including this medicinal mushroom into your diet.

What Does Lion's Mane Look Like?

The best way to identify lion's mane mushrooms are the icicle-like teeth hanging from a central stalk.

Due to their unique appearance, it’s easy to identify lion’s mane mushrooms. When in its prime, this functional mushroom looks like a white ball covered in shaggy spines.


The spines, which resemble the mane of a lion (hence the name), are short while the fungus is young, but grow to about two inches long when these adaptogenic mushrooms are ready for consumption.

As they age, lion’s mane mushrooms discolor and turn slightly yellow. If the mushroom is slightly yellow, it's still safe to eat.

However, once it turns orange, Hericium erinaceus is past its prime. If you find an orange lion’s mane, you should leave it on the tree so it can produce spores as it decays.

When and Where to Forage for Lion’s Mane?

Lion’s mane mushrooms grow on hardwood trees and dead logs. You can find wild lion’s mane growing on hardwood logs and living trees (mostly beech, maple, and oak trees). They prefer cooler climates (65-70° F), and their natural habitat is usually a lush forest in the northern part of Europe, Asia, and North America.

Lion’s mane mushrooms are at their prime in the late summer and fall. Therefore, if you plan on foraging, it’s best to do so from August to November. 

Due to their popularity, it's easy to find lion’s mane in farmer’s markets and online stores, and you can even buy a kit and grow lion’s mane at home.

Does Lion’s Mane Mushroom Have Any Look-alikes?

Lion’s mane has a unique appearance, so it's easy to differentiate it from other types of mushrooms. However, an inexperienced forager may not be able to tell the difference between Hericium erinaceus and other Hericium species.

People often confuse lion’s mane (Hericium erinaceus) for Hericium americanum (bears head tooth fungi) and Hericium coralloides (coral tooth mushroom) when foraging lion’s mane. Some say the appearance of the lion’s mane mushroom resembles the hen of the woods (maitake) fungus when past its prime.

Luckily, all of these Hericium varieties are non-poisonous, which makes the lion’s mane mushroom a great choice for a beginning forager.

Can You Eat Lion's Mane Mushrooms Raw?

Yes, you can eat lion’s mane raw, but you may not like the spongy texture of the mushroom. While lion’s mane can be delicious when cooked (the taste of Hericium erinaceus resembles lobster or crab meat) its flavor is subpar without seasoning.

Luckily, it’s easy to cook and eat lion’s mane, as you can add it to a mushroom risotto, make lion’s mane pasta, or use it as a vegan seafood alternative (for example, a lion’s mane mushroom recipe for crab cake is a must-try).

The lion’s mane dosage that works for you will differ greatly based on what you use it for. Most people start with a lower dosage (usually 750-1000 mg per day) and work their way up until they are satisfied with the effects these adaptogenic mushrooms provide.

What drugs does lion's mane interact with?
