Functional Mushroom Teas: How to Prepare Reishi, Chaga and Lion’s Mane at Home

How to Make Mushroom Tea at Home

Mushroom tea is made by simmering or steeping dried mushroom slices, chunks, or powder in hot water to draw out flavor and compounds. Tough, woody mushrooms like reishi and chaga usually need a long simmer called a decoction. Softer mushrooms like lion’s mane can often be prepared with a shorter steep, similar to a regular herbal tea. This guide walks through both methods step by step, plus how to think about DIY preparation versus buying a ready-made product.

Warning Signs to Watch For First

Before you try any mushroom tea, know the signs that mean you should stop and get medical help. Seek care right away if you notice swelling of the face, lips, or throat, trouble breathing, hives, severe stomach pain, vomiting, or a rash after drinking mushroom tea. These can be signs of an allergic reaction. If you take prescription medication or have a scheduled surgery, talk with your doctor or pharmacist before adding mushroom tea to your routine, since dietary supplements can interact with medications or affect procedures.

Decoction vs. Infusion: What’s the Difference

An infusion is a quick steep, like dropping a tea bag in hot water for a few minutes. A decoction is a longer, gentler simmer on the stove, which helps break down tougher plant and fungal material so more compounds can dissolve into the water.

• Reishi (Ganoderma lucidum): Woody and bitter. Needs a long simmer (decoction) to soften.
• Chaga (Inonotus obliquus): A hard, dense growth typically found on birch trees. Also needs a long simmer, since it will not soften with a quick steep.
• Lion’s Mane (Hericium erinaceus): Softer and more delicate. Can be prepared with a shorter simmer or infusion, closer to a standard herbal tea.

Reishi Tea: Decoction Method

Reishi is typically sold as dried slices or as a powder. Dried slices generally need more time to release their compounds than powder does.

1. Add a few dried reishi slices (or a spoonful of reishi powder) to a pot of water.
2. Bring to a low simmer, not a rolling boil.
3. Let it simmer, partially covered, for 30 minutes to 2 hours. Longer simmering with sliced reishi is common because the material is dense.
4. Strain out the solids before drinking.
5. Reishi has a strong, bitter taste. Many people add honey, ginger, or a milk of choice to balance the flavor.

Chaga Tea: Decoction Method

Chaga is nearly always prepared as a decoction because the chunks are very hard.

1. Break or grind dried chaga chunks into smaller pieces if possible, to help extraction.
2. Add the chaga to a pot of water.
3. Simmer gently, partially covered, for at least 20 minutes, and up to several hours for a stronger brew.
4. Strain and drink. Chaga has an earthy, mild flavor and is naturally caffeine-free.
5. Leftover chaga chunks can often be reused for a second or third simmer, since they release compounds slowly.

Lion’s Mane Tea: Infusion or Short Simmer

Lion’s mane is softer than reishi or chaga, so it doesn’t need as long to prepare.

1. Add dried lion’s mane slices or powder to a cup or pot of hot water.
2. For a simple infusion, steep for 10 to 15 minutes, covered, similar to steeping an herbal tea bag.
3. For a stronger brew, a gentle 20- to 30-minute simmer can be used instead.
4. Strain if using slices. Lion’s mane has a milder taste than reishi or chaga, sometimes described as slightly earthy or seafood-like.

DIY Preparation vs. Commercial Mushroom Tea Products

Both approaches have trade-offs worth thinking through before you decide.

• DIY dried mushrooms or powder: You control the mushroom-to-water ratio and the simmer time, and it’s often less expensive per serving. It takes more prep time, and you’re relying on the seller’s quality claims about species and sourcing.
• Commercial extracts and tea bags: More convenient, with consistent dosing on the label. You’re still trusting the label because dietary supplements aren’t reviewed by the FDA for safety or effectiveness before they’re sold.
• Reading the label either way: Look for the mushroom’s Latin name, whether it’s fruiting body or mycelium, and whether the product was tested by an independent lab. For help reading supplement and nutrition labels in general, see our guide to reading nutrition labels.
• Checking nutrient basics: USDA FoodData Central is a free public database where you can look up general nutrient values for raw mushroom species, separate from any marketing claims on a product label.
• Storage: Keep dried mushrooms and powders in a sealed container, away from light and moisture, to help them stay fresh longer.

What the Evidence Actually Shows

Reishi, chaga, and lion’s mane have a long history of traditional use, and researchers are actively studying their compounds. However, much of the human research so far is small, short-term, or still in early stages. Claims that mushroom tea treats or cures any disease go beyond what the current evidence supports.

The National Center for Complementary and Integrative Health notes that dietary supplements are not reviewed by the FDA for safety or effectiveness before they reach store shelves, and that what’s on the label may not always match what’s in the product. This is one reason it helps to buy from sellers who provide third-party lab testing results.

Who Should Use Extra Caution

• People who are pregnant or breastfeeding, since many dietary supplements haven’t been tested in these groups.
• People taking prescription medications, including blood thinners or immune-related drugs, since supplements can interact with medications. Our article on when to ask a pharmacist about supplements and prescriptions covers this in more detail.
• People with a scheduled surgery, since some supplements can affect bleeding or anesthesia.
• People with a known mushroom or mold allergy.
• Children, given the limited safety data in this age group.

Anyone in these groups should talk with a healthcare provider before adding mushroom tea to their routine.

Frequently Asked Questions

Does mushroom tea contain caffeine?

No. Reishi, chaga, and lion’s mane are not naturally caffeinated. If a product does contain caffeine, it’s usually because it’s blended with actual tea leaves or coffee.

Can I reuse the mushroom pieces after brewing?

Often, yes, especially with dense mushrooms like chaga and reishi. A second or third simmer will typically produce a weaker brew than the first.

How long does dried mushroom tea material stay fresh?

Properly dried mushroom slices or powder can last for many months when stored in a cool, dry, sealed container, away from direct light.

Is powder or sliced mushroom better for tea?

Powder tends to extract faster since it has more surface area, while slices may need a longer simmer. Neither form is automatically “better” — it depends on how much time you want to spend brewing and personal taste preference.
