Chest Congestion Syrup: My Simple 5-Herb Recipe for Wet Coughs
This homemade chest congestion syrup is the one I reach for when congestion turns wet and heavy. It’s simple to make in your own kitchen. It uses five herbs, water, and raw honey.
When phlegm gets thick and sticky, it’s hard to cough up. That’s when this syrup earns its spot in my fridge. Each herb plays a part in warming, soothing, and helping the chest let go of what it’s holding.
It’s not just for coughs, either. These warming herbs help dry up excess wet mucus in the lungs. They also help with some of the drainage in the nasal passages and sinuses.
Let’s walk through the herbs, the method, and the safety notes you need to know.

Ingredients
This batch makes about 3 cups of finished syrup.
| Ingredient | Amount |
|---|---|
| Licorice root (dried) | 0.5 oz |
| Cinnamon (chips or broken sticks) | 0.25 oz |
| Echinacea (dried) | 0.25 oz |
| Elecampane root (dried) | 0.25 oz |
| Ginger root | 0.125 oz dried, or about 0.375 oz fresh |
| Water | 1 quart (4 cups) |
| Raw honey | About 1 cup, or up to 2 cups for a 1:1 ratio |
I use fresh ginger whenever I have it on hand. Dried ginger works well too. Fresh ginger holds more water, so use about three times the dried amount. That’s roughly a 1-inch piece, thinly sliced.
How Each Herb Helps Clear Sticky Phlegm
Licorice Root
Licorice root is the soothing backbone of this syrup. Herbalists have long used it as a demulcent. That means it coats and calms irritated tissue in the throat and airways.

It’s also traditionally used as an expectorant. It helps thin mucus so a cough can actually move it. Its natural sweetness helps the whole blend taste better, too.
Cinnamon
Cinnamon brings warmth to the formula. Warming herbs are traditionally used when congestion feels cold, damp, and stuck.

Cinnamon also has antimicrobial properties. It adds flavor that kids and adults tend to like. A warm, cozy taste makes a remedy much easier to take.
Echinacea
Echinacea is best known for supporting the immune system. It’s often used at the first sign of a cold or chest bug.
It doesn’t break up mucus on its own. Its job here is to support the body while it works through the illness that’s causing the congestion.
Elecampane Root
Elecampane is my go-to lung herb. It has been used for centuries for deep, wet coughs with thick mucus.
It’s considered a warming expectorant. It helps loosen phlegm that’s settled in the chest so it can come up. Elecampane also contains inulin, which gives it a gentle soothing quality.

It has a strong, bitter, slightly earthy taste. The licorice, cinnamon, and honey balance it out nicely.
Ginger
Ginger is a classic warming herb for colds and coughs. It’s traditionally used to stimulate circulation and help move stagnant mucus.

Ginger may also help relax the airways and calm a scratchy throat. It adds a little spicy kick that wakes up the whole syrup.
How to Make the Syrup
- Add all five herbs and 1 quart of water to a pot. Use stainless steel or enamel, not aluminum.
- Bring it to a gentle boil, then lower the heat to a simmer. Roots and bark need this longer simmer to release their goodness. This is called a decoction.
- Simmer uncovered until the liquid reduces by half, to about 1 pint (2 cups). This usually takes 30 to 45 minutes.
- Strain the herbs out through a fine mesh strainer or cheesecloth. Squeeze the herbs to get every last drop.
- Let the liquid cool until it’s warm, not hot. Adding honey to boiling liquid can damage its beneficial enzymes.
- Stir in about 1 cup of raw honey. For a sweeter, thicker syrup, add more, up to a 1:1 ratio (2 cups honey to 2 cups decoction). More honey also helps it keep longer.
- Pour into a clean, sterilized glass jar or bottle. Label it with the name and the date.
How Much to Take
Here’s how I use this syrup in my home. Take it 3 to 5 times a day while congestion is active.
- Adults: 2 tablespoons per dose
- Children over 1 year: 1 tablespoon per dose
This is meant for short-term use while you’re congested, not every day long-term. Licorice root is the main reason why. If the congestion isn’t improving after about a week, check in with your healthcare provider.
Never give this syrup to babies under 1 year old because of the honey. For children, please check with your healthcare provider on the right amount for their age and size as needed.

Notes
- Adults: 2 tablespoons, 3 to 5 times a day
- Children over 1 year: 1 tablespoon, 3 to 5 times a day
- For short-term use only. Check with your healthcare provider if not improving after about a week.
- Do not give honey to babies under 1 year old.
- Store in the fridge for 3 to 6 months.
- Always pour from the jar. Never put spoons back in. Keep the rim clean.
- Toss if you see mold, bubbles, cloudiness, or a sour smell.
- Speak with your healthcare provider before use.
How to Store It
Kept in the fridge, this syrup can last 3 to 6 months. How long it lasts depends on how clean you keep it.
- Always pour from the jar. Never dip a spoon or dropper back into it.
- Keep the rim and lid clean and dry. Wipe drips right away.
- Use a clean spoon for each dose after pouring.
- Store it in the fridge with the lid on tight.
Anything that goes back into the jar can bring bacteria with it. That’s what shortens shelf life.
Toss it if you see mold, bubbles, cloudiness, or a sour or fermented smell. When in doubt, throw it out and make a fresh batch.
Important: No Honey for Babies Under 1 Year
Never give honey to a child under 12 months old. This includes raw honey, cooked honey, and honey in syrups.
Honey can carry Clostridium botulinum spores. A baby’s gut isn’t mature enough to stop those spores from growing. This can cause infant botulism, a serious and sometimes life-threatening illness.
Watch for signs like constipation, weak sucking or feeding, a weak cry, drooping eyelids, or floppy muscle tone. If you notice any of these, get medical care right away.
If you have a baby in the house, keep this syrup well out of reach and clearly labeled. Talk with your pediatrician before giving any herbal preparation to an infant, with or without honey.
Herb Precautions
Natural doesn’t mean right for everyone. Please read these before making this syrup.
- Licorice root: Not for long-term or heavy use. It can raise blood pressure and lower potassium. Avoid it if you’re pregnant or have high blood pressure, heart, or kidney problems.
- Elecampane: Avoid during pregnancy and breastfeeding. Skip it if you’re allergic to plants in the daisy family, like ragweed.
- Echinacea: Also in the daisy family, so the same allergy caution applies. Talk to your healthcare provider if you have an autoimmune condition.
- Ginger and cinnamon: Use caution if you take blood thinners or diabetes medications.
- Honey: Never for babies under 1 year old. Use care with diabetes, since it raises blood sugar.
If you take any prescription medications, check with your healthcare provider for interactions.
When to Contact Your Healthcare Provider
Seek care for trouble breathing, wheezing, chest pain, or a high or lasting fever. Also get help if a cough lasts more than a week or two, or brings up blood or green-brown mucus. For babies and young children, call your healthcare provider sooner rather than later.
