15 Natural Remedies to Treat and Prevent Cough
, by Aussie Pharma Direct, 13 min reading time
Coughs are a common woe, especially during the colder months when respiratory illnesses like colds and flu are more prevalent. They can also be triggered by allergies, irritants like dust or smoke, and even certain medications. While persistent coughing can be disruptive and uncomfortable, it's often the body's natural way of clearing irritants and mucus from the airways.
While modern medicine offers a plethora of options to help ease coughing fits, ranging from over-the-counter cough syrups to prescription medications, many of these solutions come with their own set of caveats. Often, the very remedies designed to alleviate cough symptoms may introduce unwanted side effects or dependencies that could compromise our overall health in the long run.
This is where exploring natural remedies for cough becomes an attractive option. These alternative approaches aim to soothe your throat, loosen mucus, and ease coughing without the potential drawbacks of conventional medications. In the next sections, we'll explore 15 natural remedies you can try at home to treat and even prevent coughs.
1. Honey and lemon
One of the most enduring and beloved natural remedies for coughs is the simple yet powerful combination of honey and lemon. This dynamic duo has been used for generations to provide relief from sore throats, ease coughing, and boost overall respiratory health.
How it works:
- Soothing properties - Honey's rich consistency helps coat the throat, providing instant relief from irritation and tickling sensations that trigger coughing. Its natural sweetness also helps to suppress cough reflexes, allowing for a more peaceful night's sleep.
- Antibacterial and antioxidant benefits - Both honey and lemon boast antibacterial and antioxidant properties, which can help fight off infections and reduce inflammation in the throat and respiratory tract. Lemon, rich in vitamin C, further bolsters the immune system, aiding in the body's defence against cough-inducing pathogens.
To create a soothing honey and lemon elixir, simply mix one to two tablespoons of raw, preferably organic, honey with the juice of half a lemon in a cup of warm water.
Safety considerations:
While honey and lemon are generally safe for consumption, it's important to note that honey should not be given to children under the age of one due to the risk of botulism.
2. Ginger tea
Ginger tea is not only a delicious beverage but also a potent natural remedy for soothing cough symptoms and supporting respiratory health. With its invigorating aroma and warming properties, ginger has long been revered for its medicinal qualities, making it a staple in traditional healing practices around the world.
How it works:

3. Steam inhalation
Steam inhalation is a time-tested natural remedy for alleviating cough symptoms and respiratory congestion. By inhaling warm, moist air infused with beneficial essential oils or herbs, steam inhalation helps to hydrate the respiratory tract, loosen mucus, and soothe irritated airways.
How it works:
- Moisturises the airways - Dry air can exacerbate cough symptoms by drying out the mucous membranes of the respiratory tract, leading to irritation and inflammation. Steam inhalation provides much-needed moisture to the airways, helping to alleviate dryness and promote comfort.
- Loosens mucus - The warm, moist air of steam inhalation helps to loosen and thin mucus in the respiratory tract, making it easier to expel through coughing or blowing the nose. This can provide relief from congestion and facilitate clearer breathing.
- Soothes irritation - Steam inhalation can help soothe irritated airways and reduce inflammation, providing relief from coughing and discomfort.
To perform steam inhalation, boil a pot of water and transfer it to a heat-safe bowl or basin. Optionally, add a few drops of essential oils like eucalyptus or peppermint for added relief. Lean over the bowl, covering your head with a towel to trap the steam, and inhale deeply for 5-10 minutes, being careful not to get too close to the hot water to avoid burns.

To prepare a saltwater gargle, simply mix about half a teaspoon of salt into a glass of warm water until it dissolves completely. Take a small sip of the saline solution and gargle it in the back of your throat for about 15-30 seconds before spitting it out.
Safety considerations:
- Avoid swallowing the saltwater solution, as it may cause dehydration or upset stomach.
- If you have high blood pressure or other health conditions that require you to limit salt intake, consult with your healthcare provider before using saltwater gargling as a remedy.
5. Eucalyptus oil
Eucalyptus oil is a potent essential oil renowned for its invigorating aroma and numerous health benefits, particularly for respiratory health. Extracted from the leaves of the eucalyptus tree, this natural remedy has properties that are beneficial to alleviate coughs, clear congestion, and promote easier breathing.
How it works:
- Decongestant properties - Eucalyptus oil contains compounds like cineole, which act as natural decongestants. Inhaling the vapours of eucalyptus oil can help to open up the airways, reduce nasal congestion, and ease respiratory discomfort associated with coughing.
- Antimicrobial effects - Eucalyptus oil possesses antimicrobial properties that can help fight off respiratory infections caused by bacteria or viruses. By inhibiting the growth of pathogens, eucalyptus oil supports the body's natural defence mechanisms and may help shorten the duration of coughs and colds.
To use eucalyptus oil for respiratory relief, add a few drops of the oil to a bowl of hot water or a steam inhaler. Inhale the steam deeply for 5-10 minutes, allowing the aromatic vapours of eucalyptus oil to penetrate your airways and provide soothing relief from cough symptoms.
Alternatively, you can dilute eucalyptus oil with a carrier oil like coconut or olive oil and apply it topically to the chest or throat area.
Safety considerations:
- While eucalyptus oil is generally safe for inhalation and topical use, it is potent and should be used with caution, especially in concentrated form.
- Avoid ingesting eucalyptus oil, as it can be toxic when taken internally
6. OPEP Devices (Oscillating Positive Expiratory Pressure)
OPEP (Oscillating Positive Expiratory Pressure) devices represent a modern approach to respiratory care, offering innovative technology to clear mucus and improve lung function. They are particularly beneficial for individuals with chronic respiratory conditions such as chronic obstructive pulmonary disease (COPD) or bronchiectasis.
How it works:
- OPEP devices work by generating positive expiratory pressure during exhalation, which helps to keep the airways open and prevent collapse. It also produces oscillations in the airways, creating a vibratory effect that helps to loosen and mobilise mucus trapped in the lungs. This enhances mucus clearance and promotes clearer breathing, reducing cough frequency and severity.
To use an OPEP device, simply exhale gently into the device while maintaining a tight seal around the mouthpiece or mask. The resistance generated by the device creates oscillations in the airways, which help to mobilise mucus and improve lung function. Perform several sets of breathing exercises with the OPEP device, following the manufacturer's instructions for duration and frequency of use.
If you’re looking for an OPEP device, one of the most reliable OPEP device in Australia is AirPhysio, which you can buy right here on Aussie Pharma Direct.

7. Probiotics
Probiotics are live microorganisms that provide numerous health benefits when consumed in adequate amounts. While often associated with digestive health, emerging research suggests that probiotics may also play a role in supporting respiratory wellness by modulating immune function and reducing the severity and duration of respiratory infections, including coughs and colds.
How it works:
- Immune modulation - Probiotics help to maintain a healthy balance of beneficial bacteria in the gut, which in turn supports immune function and enhances the body's ability to defend against respiratory pathogens.
- Anti-inflammatory effects - Imbalances in the gut microbiota have been linked to chronic inflammation, which can contribute to respiratory conditions such as asthma and allergies. Probiotics may help to reduce inflammation in the gut and throughout the body, thereby alleviating symptoms of respiratory inflammation and promoting respiratory comfort.
Probiotics can be consumed in various forms, including fermented foods like yogurt, kefir, sauerkraut, and kimchi, as well as dietary supplements containing specific strains of beneficial bacteria.
When choosing probiotic supplements, look for products that contain strains known to support immune and respiratory health, such as Lactobacillus acidophilus, Lactobacillus plantarum, and Bifidobacterium lactis.
