Herbal Allies For A Wet Cough

First, let’s cover some herbs that are wonderful for soothing a wet cough. Remember to always thoroughly research each herb you choose so that you are aware of any personal safety concerns or contraindications.

Thyme – Thymus vulgaris (leaf)

Although its original herbal uses have been largely forgotten in favor of its role in the kitchen, thyme once held an important place in home herbalism, especially in winter. 

The most noted constituent of thyme, thymol, is expectorant, antispasmodic, antimicrobial, antitussive, and bronchodilating. Thyme can be beneficial to soothe acute or chronic respiratory issues including coughs and bronchitis (Bone & Mills, 2013; Tierra, 2003). In addition, this warming spice is incorporated into winter dishes & beverages to help the body adapt to the cold.

White Horehound – Marrubium vulgare (leaf)

This somewhat bitter mint family herb is famous for soothing wet coughs and moving along the thick, damp mucus associated with allergies. Horehound was such an important herb for the lungs and bronchial system, that it used to be called “Lungenkraut” (meaning “lung-herb”) in Central Europe. (Holmes, 1997).

Horehound leaves aid with thinning mucus and clearing it from the airways while quelling spasms (Groves, 2016). Once old mucus has been expectorated, new more active immune cell containing mucus can form. This is one example of how horehound works by shifting the environment of the body so that the body can restore vitality and balance (Wood, 2008).

Furthermore, the relaxing diaphoretic nature of horehound makes it a useful herbal ally for respiratory infections that include fever, painful swollen throat, hoarseness, and sinus mucus drainage. It also carries an analgesic action, that is it has been found to ease pain, particularly pain associated with coughs and sore throats (de Souza et al., 1998).

Elecampane – Inula helenium (root)

This beautiful sunflower relative produces pungent, balsamy roots, which were traditionally used to soothe bronchial spasms, infections, and to move and clear congestion.
Just like horehound and thyme, this herb has expectorant properties that thin and move mucus, making the mucus easier to eliminate. Therefore, elecampane is helpful for making coughs more productive and hence reducing congestion. In addition to being an excellent expectorant, it also soothes the tissue irritation and inflammation that results from coughing (Hoffmann, 2003). 

Thanks to aromatic properties, elecampane root encourages movement in the respiratory tract, stimulating a better overall function and vitality. (Chevalier, 1996).

Ginger – Zingiber officinale (rhizome)

This pungent and sweet rhizome is great for adding warmth and a familiar flavor to this homemade cough syrup.

Ginger is quite the superstar when it comes to cough, cold, and flu support. Its antimicrobial properties, combined with the ability to thin mucus and support expectoration, along with its warming energetics make ginger an effective ally in working with colds and flu. Ginger’s volatile oils stimulate the immune system to fight bacterial and viral infections (McIntyre, 1996) and are so effective that it can abort the onset of upper respiratory infections (Holmes, 1997).

Homemade Cough Syrup for a Wet Cough

An herbal syrup is prepared by combining a concentrated decoction and/or infusion with honey. The honey works well for any kind of cough and increases the shelf life of the decoction. In addition, it can help increase the palatability of some herbs—

Children especially find syrups to be delicious!


2 tablespoons elecampane (Inula helenium) root, dried or fresh
1 tablespoon ginger (Zingiber officinale) rhizome, dried or fresh
2 tablespoons horehound (Marrubium vulgare) leaf, dried or fresh
2 tablespoons thyme (Thymus vulgaris) leaf, dried or fresh
1 quart of water
1 cup raw, local honey

  • Grind the herbs with a mortar and pestle.
  • Prepare a concentrated decoction with the elecampane root:
    Combine the dried elecampane root with a quart of water in a saucepan.
    Bring to a simmer and cook gently until the liquid volume reduces by half.
    Keep an eye on the decoction to ensure it stays at a gentle simmer and to be sure to remove it from heat once the liquid volume is reduced to half.
  • Prepare an infusion with the other herbs, using the finished decoction (Should be about 1-2 cups): Pour the hot, strained decoction over the ginger rhizome, horehound leaves, and thyme leaves.
    Steep for at least 1 hour though not more than 8 hours.
  • Strain with a tea strainer, cheesecloth, or French press and return the liquid to the saucepan. 
  • Add the honey to the liquid in your saucepan.
  • Warm the mixture just slightly to enable the liquid and honey to mix
    (not heating above 110 degrees Fahrenheit).
  • Using a sterilized funnel, transfer syrup into a clean, dry, sterilized glass bottle(s) or jar(s) (ideally, a dark-colored jar or bottle to protect from light exposure).
  • Label and store in the refrigerator.

To Use: Take 1 tablespoon every 4 hours for adults, 1 teaspoon every 4 hours for older children.
Shelf Life: Up to 1-2 months in the fridge.
