At Fungi Review, we strive to uncover the most powerful mushrooms for enhancing health and wellness, and Reishi is one of the most revered in traditional medicine. Known as the “Mushroom of Immortality,” Reishi is prized for its adaptogenic properties, meaning it helps the body adapt to stress and promotes overall balance. But what exactly is Reishi, how do you identify it, and how can it benefit your wellness journey? Let’s dive in.

What Is Reishi?

Reishi (Ganoderma lucidum) is a large, fan-shaped, reddish-brown mushroom that typically grows at the base of deciduous trees, particularly oaks and maples. It’s one of the most studied medicinal mushrooms due to its long history in Traditional Chinese Medicine (TCM), where it’s called Lingzhi. In ancient China, Reishi was so highly valued that it was reserved for royalty.

What makes Reishi unique is its abundance of triterpenoids, polysaccharides, and peptidoglycans, which are thought to contribute to its adaptogenic and immune-modulating properties. Today, it is often consumed in powder, extract, or capsule form to support overall well-being.

Reishi Mushroom Benefits

Reishi mushrooms have been used for centuries to promote longevity and overall wellness. Although more research is still neeeded, here are some of the potential benefits of incorporating Reishi into your routine:

1. May Help Manage Stress and Anxiety

Reishi is widely recognized for its adaptogenic properties, which means it may help the body adapt to stress and reduce feelings of anxiety. Studies suggest that Reishi can help regulate the body’s stress response by balancing cortisol levels, the hormone responsible for stress.

According to research published by the National Institutes of Health, Reishi has been shown to reduce anxiety and improve mood in animal studies. While more human studies are needed, Reishi’s calming effects make it a popular choice for those seeking natural ways to manage stress and promote relaxation.

How it may help: If you’re dealing with chronic stress or anxiety, Reishi may support a calmer mind and body by promoting a balanced stress response.

2. May Support Immune Health

Reishi is one of the most well-known mushrooms for immune support. It contains beta-glucans and other polysaccharides that may enhance the activity of white blood cells, which are critical in defending the body against infections.

Some studies suggest that Reishi may help modulate the immune system, making it more efficient in responding to pathogens while also helping to regulate overactive immune responses in autoimmune conditions. The book "Herbal Medicine" has also indicated that Reishi may increase the activity of natural killer (NK) cells, which play a key role in combating viruses and tumor cells.

How it may help: Regular consumption of Reishi may help fortify your immune system, supporting the body’s natural defenses against illness.

3. Potential Anti-Cancer Properties

Reishi mushrooms have been extensively studied for their potential role in cancer prevention and treatment support. Some of the active compounds in Reishi, such as triterpenes and polysaccharides, are believed to have anti-tumor properties, which may inhibit the growth of cancer cells.

One study published by the National Cancer Institute found that Reishi extracts may help slow the progression of certain types of cancer by enhancing the body’s immune response. However, it’s important to note that while Reishi shows promise in cancer research, it should never be used as a substitute for conventional treatment. Always consult with a healthcare provider when considering Reishi as a complementary therapy.

How it may help: Reishi may provide support during cancer treatment by potentially enhancing immune function and reducing the side effects of chemotherapy, but it should be used alongside standard medical care.

4. May Improve Sleep Quality

One of Reishi’s lesser-known benefits is its potential to improve sleep quality. Due to its calming and adaptogenic properties, Reishi is often used as a natural sleep aid. Reishi contains compounds that may help reduce sleep latency (the time it takes to fall asleep) and improve deep sleep by promoting relaxation and reducing stress.

In a study conducted on rats published by the National Library of Medicine, Reishi extract was found to increase non-REM sleep, the deepest stage of sleep. While more human studies are needed, many people report that Reishi helps them fall asleep faster and stay asleep longer, making it a popular choice for those struggling with insomnia or poor sleep quality.

How it may help: If you have trouble falling asleep or staying asleep, Reishi may support better sleep patterns by helping to calm the nervous system and promote relaxation. 

5. May Help Alleviate Inflammation

Reishi mushrooms are widely recognized for their potential anti-inflammatory effects, making them a popular choice for individuals looking to manage inflammation-related conditions. Reishi contains triterpenoids and polysaccharides, compounds believed to reduce inflammation by inhibiting the production of pro-inflammatory cytokines, which are molecules that promote inflammation in the body.

Many users as well as studies reported by WebMD reported that taking Reishi has helped manage chronic inflammation, which is often linked to conditions such as arthritis, asthma, and irritable bowel syndrome (IBS). This research suggests that by reducing inflammation, Reishi may help improve joint health, ease respiratory symptoms, and support overall comfort and mobility.

How it may help: Reishi may help reduce inflammation throughout the body, making it a natural option for those seeking relief from inflammatory conditions.

How to Identify Reishi Mushroom

Reishi mushrooms are relatively easy to identify thanks to their distinctive appearance. Here’s what to look for:

• Color: Reishi mushrooms are typically reddish-brown with a glossy, varnish-like surface. The underside is pale white to yellowish.
• Shape: They have a fan-shaped or kidney-shaped cap with a smooth, woody texture. The mushroom can grow quite large, reaching up to 12 inches in diameter.
• Habitat: Reishi mushrooms grow on dead or dying hardwood trees, particularly oak and maple, in humid environments. They can be found in both tropical and temperate climates.

If you plan to forage for Reishi mushrooms, be sure to properly identify them and harvest responsibly to preserve the ecosystem.

How Reishi Is Grown and Sourced

Reishi can be wild-harvested or cultivated in controlled environments. Wild Reishi is often considered more potent due to the harsher conditions it grows in, which may enhance its medicinal properties. However, cultivated Reishi can also be a great option, especially if grown sustainably.

When purchasing Reishi supplements, it’s important to understand the source of the mushrooms and the extraction methods used. Look for organic and sustainably harvested Reishi to ensure you’re getting a high-quality product.

Choosing the Best Reishi Supplements

With the growing popularity of Reishi, the market is flooded with various supplements. Here’s what to look for when choosing high-quality Reishi products:

• Source Location: Check the origin of the mushrooms. Reishi from temperate forests in North America and Asia is often of the highest quality.
• Dual Extraction: Reishi contains both water-soluble and alcohol-soluble compounds. Look for supplements that use dual extraction methods to ensure you’re getting the full range of beneficial compounds, including polysaccharides and triterpenes.
• Beta-Glucan and Triterpene Content: High-quality Reishi supplements will list the beta-glucan and triterpene content, two key compounds responsible for Reishi’s immune-boosting and adaptogenic effects.
• Third-Party Testing: Opt for supplements that undergo third-party testing to verify their purity, potency, and absence of contaminants.
• No Fillers: Avoid products with unnecessary fillers like grains or starches. Stick to 100% Reishi extract for maximum benefit.
