What Is Reishi?
Reishi, also known as Lingzhi or lacquered polypore, is one of the most celebrated medicinal mushrooms in traditional Eastern medicine. Revered for more than 2,000 years in China and Japan, it earned the title “mushroom of immortality” thanks to its profound effects on longevity, vitality, and immune function.
This isn’t a mushroom you’d toss into a stir-fry. Reishi is woody, bitter, and tough — but what it lacks in taste, it makes up for in adaptogenic power. It works on multiple body systems at once: immune, nervous, hormonal, and circulatory. If your body needs to rebalance after stress, fatigue, or illness, Reishi is like a natural nighttime regeneration coach.
What Does Reishi Contain?
Reishi owes its health effects to a wide array of biologically active compounds:
| Compound | Amount per 100 g |
|---|---|
| Polysaccharides (beta-glucans) | approx. 10–15 g |
| Triterpenoids (e.g. ganoderic acids) | 2–5 g |
| Protein | 10–15 g |
| Fiber | 50–60 g |
| Iron | 6–8 mg |
| Calcium | 80–100 mg |
| Vitamin D2 (ergocalciferol) | 100–150 IU |
Reishi also contains trace minerals like potassium, magnesium, zinc, and selenium, which contribute to its antioxidant and immune-supportive properties.
How Does It Support Health?
Reishi is a true adaptogen — meaning it helps the body adapt to stress and return to balance. It modulates the immune system, reduces inflammation, supports the liver, calms the nervous system, and protects the body from oxidative damage.
It is especially useful for those experiencing:
- Chronic stress and high cortisol
- Poor sleep or insomnia
- Weakened immunity
- Autoimmune imbalance (used cautiously)
- Allergies and overactive histamine response
- Fatigue and burnout
- Liver overload and sluggish detoxification
- Cognitive fog and aging-related memory decline
Importantly, Reishi may be beneficial in managing:
- ADHD
- Insulin resistance
- Type 2 diabetes
- Leaky gut syndrome
What Are Its Brain Benefits?
Reishi is particularly supportive of the nervous system. Scientific studies show it:
- Enhances GABA receptor activity, promoting calmness and sleep
- Reduces neuroinflammation, linked to anxiety and neurodegeneration
- Supports neurogenesis (the growth of new neurons)
- Regulates the HPA axis (hypothalamic-pituitary-adrenal), restoring balance to the stress response
- Improves mental clarity, focus, and emotional resilience
This makes it an excellent tool for people struggling with ADHD, chronic stress, insomnia, brain fog, or mood swings.
What Are Its Other Uses?
In natural health traditions, Reishi is used to:
- Support liver regeneration and detox
- Boost immune defense during viral or bacterial infections
- Support cancer recovery (as an adjunct therapy)
- Improve skin tone and slow visible aging
- Aid in recovery from chronic fatigue or adrenal exhaustion
In skincare, extracts of Reishi are added to serums for their anti-inflammatory and antioxidant effects.
In the kitchen, Reishi is most commonly brewed as a bitter tea, simmered in broths, or blended into calming elixirs.
Did You Know…
In ancient Japan, wild Reishi was so rare and sacred that it was reserved only for emperors and noble families. It was believed to bestow mental clarity, long life, and spiritual power.
Today, modern science is beginning to validate these traditional beliefs. For example, a 2021 study in Frontiers in Pharmacology reported that Reishi extract may:
- Activate NK (natural killer) cells, which help the body fight cancer
- Reduce neuroinflammation associated with aging and neurodegeneration
- Enhance immune function even during chemotherapy
How to Use Reishi
Reishi works best when taken consistently over time — its effects are cumulative, not immediate.
Recommended usage:
- Powdered extract: 1–2 g daily
- Tincture: follow manufacturer dosage
- Tea or decoction: simmer 2–5 g of dried mushroom in water for 30–60 minutes
- Capsules: choose standardized extracts (e.g. 30% beta-glucans)
Best taken in the morning (to support clarity) or evening (to support sleep). Combine with vitamin C for enhanced beta-glucan absorption.
Some herbalists recommend 6–8 week cycles with short breaks to maintain long-term efficacy.
What to Combine It With?
Reishi can be combined with other adaptogens and medicinal mushrooms for enhanced effect:
- Ashwagandha – balances cortisol and supports mood
- Lion’s Mane – boosts cognition and nerve regeneration
- Chaga – supports immunity and antioxidant defense
- Cordyceps – boosts physical energy and endurance
Together, they form a powerful “rest and repair” protocol.
Who Should Be Cautious?
While Reishi is considered safe for most people, there are a few situations where caution is advised:
- People with autoimmune conditions (Reishi may stimulate immune activity)
- Individuals on immunosuppressive medication
- People taking blood thinners (e.g. warfarin) — Reishi may increase bleeding risk
- Pregnant or breastfeeding women (only under medical supervision)
- Individuals experiencing detox reactions (fatigue, diarrhea, rash) when starting — start with a lower dose
Always consult a medical professional before starting new supplements.
