They look like fungi stalactites, as their icicle shape gives them the formation of a mane, resembling the king of the jungle.
For centuries, lion’s mane mushrooms have been used as edible and medicinal mushrooms — especially in traditional Chinese medicine — according to the World Journal of Gastroenterology. Like with many Eastern remedies, people in the West began using lion’s mane mushrooms as alternatives to traditional medical treatments.

Also known as Hericium erinaceus, lion’s mane mushrooms are unique due to their shaggy shape. As they grow, they sprout downward, forming a lion’s mane. These white mushrooms contain bioactive substances known for improving heart, gut and brain health. Most studies on lion’s mane mushrooms were conducted on animals (such as rats and mice) and not humans. More studies are needed to determine how lion’s mane specifically affects human beings.
Moreover, lion’s mane mushrooms are not drugs. They also don’t provide any psychedelic effects like other mushrooms can. According to a 2020 study, lion’s mane mushrooms may be beneficial when seeking neurocognitive benefits.
Finding lion’s mane mushrooms in stores can be difficult, depending on where you live. Because it isn’t a traditional mushroom, you likely won’t find lion’s mane mushrooms at farmer’s markets or regular grocery stores. However, you should be able to find them at specialty health food stores like Whole Foods. You can also buy them in supplement form from vitamin stores, health food outlets and online retailers.
You can find lion’s mane mushrooms in the wild, as they grow on beech, oak and maple trees in North America, Asia and Europe, per the Mycelium Society. If you want to forage for them, the best time to gather lion’s mane mushrooms is in the late summer or early fall. Before you embark on a gathering quest, research whether your area allows you to forage for lion’s mane mushrooms, as some areas prohibit it.
If you live where foraging for lion’s mane mushrooms is permitted, make sure you can adequately identify these mushrooms before picking them. Or, find an expert who can help, ensuring you do not select the wrong mushroom. Then, see where they grow and check for ripeness. You’ll know it’s ripe by feeling the mushroom. If it’s spongy and soft, you’re good to go. Take a knife to remove the mushroom while leaving the roots. When you return home, cook the mushrooms immediately or store them in a paper bag in your fridge for up to three days.
Lion’s mane mushroom benefits
There are many potential benefits you may receive from lion’s mane mushrooms, such as:
- Anxiety reduction: A 2018 study showed that mice who ingested lion’s mane mushroom extract experienced antidepressant-like effects. One human 2010 study, in which menopausal women who ate four cookies with lion’s mane mushroom daily for a month, found that lion’s mane may reduce anxiety and depression.
- Ulcer prevention: Ulcers develop anywhere in your digestive tract due to the overgrowth of H. pylori and mucous layer damage from long-term nonsteroidal anti-inflammatory drug, or NSAID, use. Taking lion’s mane mushrooms can inhibit the growth of the bacteria H. pylori and protect the stomach lining.
- Heart disease risk reduction: A 2013 study on rats found that taking lion’s mane mushroom extract reduced triglyceride levels, one of the main reasons people develop heart disease.

- Fights cancer cells: Several medical studies found that combining lion’s mane mushroom with human cells creates a powerful defense mechanism that kills cancer cells faster. These studies included blood, liver and gastrointestinal cancers. Another 2013 study on mice with colon cancer found that taking the mushroom reduced the cancer spread to the lungs by up to 69%.
- Improves brain health: Lion’s mane earned the distinction as the “smart mushroom” for the benefits it can offer the brain. A 2009 study found that people aged 50 to 80 with mild cognitive impairments who took 250-milligram tablets containing lion’s mane powder three times a day for 16 weeks scored higher on cognitive tests than the other group who only took a placebo.
- Reduces inflammation: Inflammation can cause many medical conditions such as cancer, heart disease and arthritis.
