While some home remedies are commonly suggested for clearing mucus from the lungs, it’s important to note that scientific evidence supporting their effectiveness is limited. The following natural remedy incorporating onion juice, honey, and lemon juice is often mentioned, but it’s important to remember that individual experiences may vary and consulting with a healthcare professional is recommended for persistent respiratory symptoms.

Here is a recipe for the natural remedy 


  • 1 tablespoon onion juice
  • 1 tablespoon honey 
  • 2 tablespoons lemon juice

To prepare the remedy:

  1. Combine 1 tablespoon of onion juice, 1 tablespoon of honey, and 2 tablespoons of lemon juice in a cup.
  2. If desired, add 1 tablespoon of apple cider vinegar and a small amount of grated ginger.
  3. Mix the ingredients well.
  4. Add water to the mixture to dilute it as desired.
  5. Drink the mixture three times a day.

It’s important to note that the effectiveness of this remedy is not scientifically proven, and individual results may vary. While onions, honey, and lemon juice have certain potential health benefits, their specific effects on clearing mucus from the lungs are not well-established.

Onion :

 Onions do contain certain compounds that have been shown to have antihistamine properties. One of these compounds is quercetin, a flavonoid that is found in various plant foods, including onions.

Quercetin has been studied for its potential antihistamine effects. Research suggests that it can inhibit the release of histamine from mast cells, which are involved in the allergic response. By reducing histamine release, quercetin may help alleviate allergy symptoms such as sneezing, itching, and congestion.

A study published in the journal Pharmacognosy Reviews in 2016 discussed the antiallergic effects of quercetin and its potential as a natural antihistamine. The authors highlighted its ability to inhibit the release of histamine and other inflammatory mediators.

Another study published in the journal Pharmacology in 2012 investigated the effects of quercetin on allergic rhinitis, a condition characterized by inflammation of the nasal passages. The researchers found that quercetin supplementation significantly reduced nasal symptoms and improved quality of life in individuals with allergic rhinitis.

While these studies indicate the potential antihistamine properties of quercetin, it’s important to note that the concentrations of quercetin in onions may not be as high as those used in research studies. Consuming onions as part of a balanced diet can contribute to overall health and may provide some antihistamine effects, but it may not be sufficient as a standalone treatment for allergies.

It’s always recommended to consult with a healthcare professional for proper diagnosis and management of allergies or any other health conditions. They can provide personalized advice and recommend appropriate treatment options based on your specific needs.

Honey has been used as a natural remedy for coughs and throat irritations for centuries. It is believed to have several beneficial properties that can help soothe coughs and clear mucus. Here are some ways in which honey may be beneficial for cough and mucus relief, supported by scientific studies:

  1. Soothes the Throat: The thick and viscous consistency of honey helps coat the throat, providing relief from coughing and soothing irritation. A study published in the journal Archives of Pediatrics & Adolescent Medicine found that honey was more effective at relieving nocturnal cough symptoms in children than a cough suppressant medication or no treatment at all.
  2. Antimicrobial Properties: Honey possesses antimicrobial properties that can help fight off infections that may contribute to cough and mucus production. It contains hydrogen peroxide, which has antibacterial activity. Additionally, some types of honey, such as Manuka honey, have unique antibacterial properties attributed to their high levels of methylglyoxal. A study published in the Journal of Microbiology, Immunology, and Infection found that Manuka honey inhibited the growth of respiratory pathogens.
  3. Antioxidant Effects: Honey contains antioxidants that can help reduce inflammation and support the immune system. The antioxidants in honey, such as phenolic compounds, may help alleviate cough symptoms. A study published in the journal BMC Complementary and Alternative Medicine demonstrated the antioxidant activity of different types of honey and their potential to reduce oxidative stress.

It’s important to note that honey should not be given to infants younger than 1 year old due to the risk of infant botulism. However, for older children and adults, consuming honey, particularly raw and unprocessed varieties, can be a natural and effective way to relieve coughs and clear mucus.

Remember to use honey as a complementary treatment and consult with a healthcare professional if your symptoms persist or worsen.

Lemon is a citrus fruit known for its refreshing flavor and vibrant yellow color. It is not only a popular ingredient in culinary preparations but also offers several medicinal benefits. Here are some of the medicinal benefits of lemon supported by recent research:

  1. Rich in Vitamin C and Antioxidants: Lemons are an excellent source of vitamin C, a potent antioxidant that helps protect the body against oxidative stress and supports immune function. A study published in the journal Nutrients highlighted the role of vitamin C in immune defense and its potential benefits in reducing the duration and severity of respiratory tract infections.
  2. Digestive Health: Lemon has been traditionally used to promote digestion. It stimulates the production of digestive juices, such as bile, which aids in the breakdown of fats. Research published in the journal Food Chemistry suggested that lemon extract exhibited significant protective effects on the gastrointestinal tract and demonstrated potential in the treatment of digestive disorders.
  3. Anti-inflammatory Properties: Lemon contains compounds with anti-inflammatory properties, such as flavonoids and limonoids. These compounds help reduce inflammation in the body, which is linked to various chronic diseases. A study published in the Journal of Medicinal Food demonstrated the anti-inflammatory effects of lemon extract in reducing inflammatory markers in cells.
  4. Antibacterial and Antiviral Activity: Lemon has shown antibacterial and antiviral activity against various pathogens. A study published in the Journal of Food Science found that lemon juice exhibited antimicrobial activity against foodborne pathogens, including Escherichia coli and Salmonella. Lemon also possesses antiviral properties against certain viruses, as shown in a study published in the journal Virology Journal.
  5. Weight Management: Some research suggests that lemon may have a positive impact on weight management. A study published in the Journal of Clinical Biochemistry and Nutrition indicated that lemon polyphenols helped reduce body weight gain and fat accumulation in mice fed a high-fat diet.

It’s important to note that while lemon offers potential health benefits, it should be consumed as part of a balanced diet and not as a sole treatment for medical conditions. Always consult with a healthcare professional for personalized advice.
