What You'll Learn
Lion's mane mushrooms have been used in traditional medicine for centuries
Lion's mane mushrooms, scientifically known as Hericium erinaceus, are large, white mushrooms with dangling spines that resemble a lion's mane. They are found most abundantly in East Asia and have been used for centuries in traditional Chinese medicine.
In traditional Chinese medicine, lion's mane mushrooms are believed to support all five internal organs: the liver, spleen, lung, heart, and kidney. The mushroom is also said to combat the deficiency of Qi, or "life force". Buddhist monks would make tea using lion's mane mushroom powder to enhance brain function and improve their focus during meditation.
Lion's mane mushrooms have been purported to have multiple beneficial effects, including antioxidant, antidiabetic, antilipidemic, antihypertensive, antineoplastic, immunomodulatory, hepatoprotective, neuroprotective, and cardiovascular protective properties. They are also believed to have anti-inflammatory effects, which can reduce symptoms of anxiety and depression.
Modern science suggests that lion's mane mushrooms may have several health benefits, including fighting dementia, treating nerve damage, managing diabetes, preventing ulcers, and improving heart health. However, research in humans is still limited, and no products made from lion's mane mushrooms have been approved for the treatment of any condition.

They have been shown to have anti-inflammatory effects
Lion's mane mushrooms (Hericium erinaceus) are white, globe-shaped fungi with long, shaggy spines. They have been used in traditional Chinese medicine for centuries and are now available as a food, supplement, or extract.
Lion's mane mushrooms contain anti-inflammatory compounds that have been shown to reduce inflammation in the body. Inflammation is a contributing factor to many medical conditions, including diabetes, heart disease, and autoimmune diseases. Research has found that lion's mane mushroom extract has anti-inflammatory effects that can reduce symptoms of anxiety and depression in mice. Other animal studies have found that lion's mane extract may help regenerate brain cells and improve the functioning of the hippocampus, a region of the brain that processes memories and emotional responses. Researchers believe that improved hippocampus functioning may explain the reductions in anxious and depressive behaviours in mice receiving these extracts.
A 2023 animal study found that lion's mane supplementation promoted the growth of beneficial gut bacteria while reducing harmful ones, showing a prebiotic effect. This may help improve gastrointestinal health and manage disorders like inflammatory bowel syndrome (IBS) and inflammatory bowel disorder (IBD). Additionally, extracts from lion's mane mushrooms may provide healing benefits for skin wounds.
Lion's mane mushrooms also contain antioxidant compounds that may help reduce the impact of illnesses. A 2021 study found that lion's mane exhibits high antioxidant activity, especially when researchers used ethanol to extract its bioactive compounds. These antioxidants may fight inflammation and oxidation in the body and boost the immune system.
While the current research on the anti-inflammatory effects of lion's mane mushrooms is promising, more studies involving humans are needed to develop practical health applications.

They may help regenerate brain cells
Lion's mane mushrooms, also known as hou tou gu or yamabushitake, have been used in traditional Chinese medicine for centuries. They are large, white, shaggy fungi that resemble a lion's mane and are known for their potential brain health benefits. One of their most intriguing potential benefits is their ability to promote brain cell regeneration.
Research has suggested that lion's mane mushrooms contain compounds that can stimulate the growth and regeneration of brain cells, a process known as neurogenesis. In particular, two classes of compounds, hericenones and erinacines, have been identified as potential neurogenesis promoters. These compounds have been shown to stimulate the production of nerve growth factors, which are proteins that play a critical role in the growth, maintenance, and survival of neurons.
A number of animal studies have provided evidence to support these brain regenerative effects. For example, one study found that rats with induced memory deficits who were treated with lion's mane mushroom extract showed improved cognitive function and increased levels of nerve growth factors in the brain. Similarly, another study found that aged rats who consumed lion's mane mushroom extract exhibited improved memory and learning abilities, along with increased brain plasticity and reduced inflammation in the brain.
While the research is still ongoing and most studies have been conducted on animal models, the potential for lion's mane mushrooms to promote brain cell regeneration is promising. For individuals looking to support their brain health and possibly enhance cognitive function, incorporating lion's mane mushrooms into their diet or taking supplements may offer beneficial effects. However, as with any dietary change or supplement, it is always recommended to consult with a healthcare professional beforehand.

They could help manage diabetes
Lion's mane mushrooms (also known as lion's mane or yamabushitake) are large, white mushrooms that resemble a lion's mane. They are usually described as having a seafood-like flavour and can be eaten raw, cooked, dried, or steeped as a tea. They are also available in supplement form as powders, liquids, and capsules.
Lion's mane mushrooms have been used in traditional medicine for centuries, particularly in Asian countries such as Korea, Japan, India, and China. Modern science suggests that the mushrooms may have health benefits, including managing diabetes. However, it is important to note that research in humans is still limited, and no product made from the mushrooms has been approved for the treatment of any condition.
- Lowering blood sugar levels: Lion's mane mushrooms have been shown to lower blood sugar levels in animal studies. One possible mechanism is by blocking the enzyme alpha-glucosidase, which breaks down carbohydrates in the small intestine. Lowering blood sugar is crucial in diabetes management, as the disease is characterised by elevated blood sugar levels.
- Reducing diabetic nerve pain: In mice with diabetic nerve damage, lion's mane extract reduced pain and improved antioxidant levels. Diabetic nerve pain is a common complication of chronically high blood sugar levels.
- Improving antioxidant levels: Lion's mane mushrooms contain potent antioxidants, which can help mitigate the damage caused by free radicals in the body. Oxidative stress is implicated in the development of diabetes and its complications.
- Reducing risk factors for heart disease: Diabetes is a risk factor for cardiovascular disease. Lion's mane mushrooms have been shown to improve fat metabolism, lower triglyceride levels, and reduce cholesterol oxidation, all of which contribute to a reduced risk of heart disease.
- Slowing blood clotting: Lion's mane mushrooms contain a compound called hericenone B, which can slow blood clotting. This may lower the risk of heart attack or stroke, which are more common in individuals with diabetes.
While the potential benefits of lion's mane mushrooms in diabetes management are promising, more research is needed, especially in human studies, to determine the efficacy and appropriate dosage for therapeutic use. It is always recommended to consult a healthcare professional before using any dietary supplement, including lion's mane mushrooms, to manage a medical condition.
