Functional mushrooms — reishi, lion's mane, chaga, cordyceps — are the biggest superfood trend of 2026, showing up in coffee, hot chocolate, and wellness capsules everywhere. What most of the Western wellness industry discovered last year, Traditional Chinese Medicine has been classifying for more than two thousand years. Reishi (ling zhi, 灵芝) was literally called the "mushroom of immortality," and lion's mane (hou tou gu, 猴头菇) has been a treasured cooking mushroom in Chinese cuisine for centuries. Here is what these two functional mushrooms actually do, how to cook with them tonight, and how to buy them without getting ripped off.
- 2,000+ years — Reishi is classified as a top-grade herb in the Shennong Bencao Jing, China's oldest surviving materia medica (~200 CE), alongside ginseng and jujube.
- 6 colors of zhi — The classical text documents six color-coded reishi varieties (red, black, white, yellow, green, purple), each with distinct properties; red reishi is the most studied today.
- 1 RCT, PMID 36766186 — A 2023 randomized controlled trial in Foods found a reishi beta-glucan associated with increased natural killer cell activity and T-cell proliferation in healthy adults.
- 2 mushrooms, 2 jobs — Reishi for the evening (calm, sleep, immune support), lion's mane for the daytime (focus and digestion). Start with one, cooked as food, for 2–4 weeks.
🧪 What the Science Says
A 2023 randomized controlled trial published in Foods (PMID: 36766186, DOI: 10.3390/foods12030597) evaluated a β-1,3; 1,6-D-glucan derived from Ganoderma lucidum (reishi) in healthy adults. The trial found that supplementation was associated with enhanced markers of innate and adaptive immune activity — including increased natural killer cell activity and T-cell proliferation.
For lion's mane, early research suggests compounds called hericenones and erinacines may support nerve growth factor signaling in laboratory models, though well-controlled human studies remain limited. A [YEAR] review in [JOURNAL] explored these compounds' potential role in cognitive support — a direction worth watching, not yet a settled claim.
⚠️ Safety Note
Reishi and lion's mane are food-grade mushrooms, generally recognized as safe (GRAS) when cooked and eaten. However, reishi has natural blood-thinning and blood-pressure-lowering properties, so it may interact with anticoagulant and antihypertensive medications. If you are pregnant, breastfeeding, on immunosuppressants, or preparing for surgery, check with your healthcare provider before using concentrated extracts. See our full disclaimer. This article is food-based dietary guidance, not medical advice.
"Ling Zhi (reishi) is ranked among the superior, top-grade herbs: long-term consumption lightens the body and prolongs life." — Shennong Bencao Jing (Divine Farmer's Classic of Materia Medica, ~200 CE)
Reishi (Ling Zhi) — The Mushroom of Immortality
In TCM's most ancient text, reishi sits in the highest herb category — not for treating a disease, but for sustaining health over a lifetime. Its Chinese name ling zhi (灵芝) translates roughly to "spirit mushroom," and its classical actions read like a definition of resilience: it calms the spirit, nourishes the heart, supports the defensive qi (your immune perimeter), and tonifies qi and blood without being heating or drying. It is one of the few tonics TCM considers safe to take preventively, in the same family as ginseng and astragalus.
Because reishi is bitter, woody, and slow to release its compounds, TCM almost never eats it raw — it is decocted (simmered) into tea or broth, or taken as a concentrated extract. The bitterness is the medicine: reishi's triterpenes, responsible for that taste, are among its most studied active compounds. Modern preparations also emphasize beta-glucans, the immune-modulating fibers measured in the 2023 trial above.
Who is reishi for in practical terms? The person who is run down, sleeping poorly, catching every cold that goes around the office, and feeling wired at night. In TCM language: heart spirit unsettled, defensive qi weak. Reishi is the evening mushroom — it calms rather than energizes.
🍄 Reishi Calm Tea (灵芝安神茶)
🛒 Ling Zhi · 灵芝 · Dried Reishi Slices- 2–3 thin slices of dried reishi (or 1 teaspoon reishi powder, added at the end)
- 3 dried jujube dates (red dates, hong zao) — for sweetness and heart nourishment
- 1 tablespoon goji berries — for kidney and liver nourishment
- 3 cups of water
- Rinse the reishi slices. Place them in a pot with the jujubes and water.
- Bring to a boil, then reduce to a gentle simmer.
- Simmer uncovered for 20–30 minutes — the water will turn dark amber and smell earthy and bitter.
- Add the goji berries in the last 5 minutes (they lose color and nutrients if boiled long).
- Strain into a mug. Sip warm in the evening, 1–2 hours before bed. The leftover slices can be re-simmered once.
Evening, when you feel run down or wired. This is a cumulative tonic — a cup 4–5 evenings a week for several weeks, not a one-night fix.
Lion's Mane (Hou Tou Gu) — The Focus Mushroom
Lion's mane gets its Chinese name hou tou gu (猴头菇, "monkey head mushroom") from its cascading white spines. Unlike reishi, which is medicine first and food second, lion's mane has always been a cooking mushroom — one of the famous "mountain delicacies" of Chinese cuisine, served in soups and stir-fries for its seafood-like flavor and its traditionally understood benefit to the Spleen and Stomach. In TCM terms, a strong Spleen means your body actually converts the food you eat into usable qi and blood instead of dampness and fatigue.
The modern angle is focus. Western supplement culture has adopted lion's mane as the "brain mushroom" based on laboratory research into hericenones and erinacines, compounds that appear to stimulate nerve growth factor (NGF) in cell and animal studies. TCM's traditional reading is compatible but broader: nourish the Spleen and Stomach, and the mind (which depends on adequate qi and blood reaching the head) clears up on its own. Either way, it is a daytime mushroom — energizing and grounding rather than sedating.
Who is lion's mane for? The person who is scattered, foggy after meals, running on coffee, or dealing with sluggish digestion. In TCM language: Spleen qi deficiency with a side of mental fatigue. It is also simply a delicious mushroom — the most beginner-friendly way to start with functional mushrooms is to cook lion's mane like any other mushroom.
🥣 Lion's Mane & Chicken Soup (猴头菇鸡汤)
🛒 Hou Tou Gu · 猴头菇 · Dried Lion's Mane- 2 pieces of dried lion's mane (soaked 30 minutes in warm water, then squeezed gently) — or 150g fresh
- 2 chicken thighs (or 4 cups vegetable broth for a vegetarian version)
- 3 slices fresh ginger
- 1 handful goji berries
- 6 cups of water · salt to taste
- Soak the dried lion's mane in warm water for 30 minutes, then gently squeeze out the soaking liquid and tear into bite-sized pieces. (The soaking water is flavorful — strain and use it as part of the broth.)
- In a pot, add the chicken, ginger, and lion's mane. Cover with water and bring to a boil.
- Skim any foam, reduce to a simmer, and cook for 45 minutes.
- Add the goji berries and salt in the last 10 minutes.
- Serve hot. Eat the lion's mane pieces — they have a satisfying, crab-meat-like texture.
A weekend lunch or a make-ahead dinner. One bowl of this soup delivers the full-food version of lion's mane — the traditional preparation — plus a complete meal for your Spleen.
Reishi vs. Lion's Mane: Which Is Right for You?
| Reishi (Ling Zhi) | Lion's Mane (Hou Tou Gu) | |
|---|---|---|
| TCM nature | Neutral-warm, bitter, sweet | Warm-neutral, sweet |
| Meridians | Heart, Lung, Liver, Kidney | Spleen, Stomach |
| Classical role | Calm the spirit, support defensive qi | Strengthen digestion, nourish the middle |
| Best for | Restless sleep, feeling run down, immune support | Mental fog, focus, sluggish digestion |
| Time of day | Evening — calming | Daytime — grounding, energizing |
| How to use | Decocted tea/broth, or dual-extracted supplement | Cooked as food (soup, stir-fry), or powder |
| Flavor | Bitter, woody — acquired taste | Mild, seafood-like, genuinely delicious |
The two are complementary, not competing. A common pattern: lion's mane during the day for focus and digestion, reishi tea in the evening for calm sleep. Both support the immune system from different angles — reishi through the defensive qi, lion's mane through the Spleen's production of qi and blood. Start with whichever matches your dominant complaint, give it 2–4 weeks of daily use, and observe.
How to Buy Functional Mushrooms (Without Getting Ripped Off)
The functional mushroom aisle is crowded with marketing. Three checks will separate real products from noise:
1. Whole mushrooms beat mystery powders. For cooking, buy whole dried reishi slices and whole dried lion's mane — you can see exactly what you are getting, and it is the cheapest form per dose. Powders labeled simply "mushroom blend" may contain grain substrate (the mycelium grown on rice) rather than the fruiting body. Labels should state "fruiting body" and the species name (Ganoderma lucidum, Hericium erinaceus).
2. Reishi needs extraction. Reishi's beneficial compounds are locked behind tough cell walls; the classic Chinese preparation is a long simmer, and commercial products should state "dual-extracted" (hot water + alcohol) to capture both beta-glucans and triterpenes. If a reishi powder doesn't mention extraction, be skeptical.
3. Third-party testing matters. Look for products tested for heavy metals (mushrooms are notorious accumulators) and stated beta-glucan percentage. A reputable brand publishes its certificate of analysis. This matters more than the price tag.

Frequently Asked Questions
Can I take reishi and lion's mane together?
Yes. In TCM the two mushrooms are complementary: reishi calms the spirit and supports defensive qi, while lion's mane supports the Spleen and Stomach. A common rhythm is lion's mane during the day and reishi tea in the evening. If you take prescription medication — especially blood thinners or blood-pressure medication — check with your healthcare provider first, because reishi is a food-herb with active compounds.
How long do functional mushrooms take to work?
Treat them like food therapy, not pills: benefits build with consistent daily use over weeks rather than hours. Traditional practice suggests 2–4 weeks of daily preparation for noticeable changes, and classical texts emphasize long-term, cumulative use — the Shennong Bencao Jing lists reishi among "top-grade" herbs meant for sustained consumption.
Are functional mushroom powders as good as whole mushrooms?
For reishi, a properly extracted product (dual-extracted with hot water and alcohol) concentrates the triterpenes and beta-glucans that whole dried slices release only slowly in soup. For lion's mane, whole cooked mushrooms are the complete food and the traditional choice; powder is a convenient supplement. In both cases, look for third-party-tested products that state the extraction method and beta-glucan percentage.
