The lungs are organs responsible for the exchange of gases like oxygen and carbon dioxide in the body. Pollutants like smog, cigarette smoke, and everyday chemicals can lead to decreased lung function, as can conditions like asthma and influenza. Fortunately, there are a variety of herbal and nutritional supplements that can help protect lung function and provide symptom relief during infections.
Herbal Supplements
Mullein is among the most frequently recommended herbs for respiratory conditions. According to WebMd.com, the alkaloids in mullein may have the ability to fight influenza and the bacteria that cause infection in the lungs. Mullein has been used for centuries and is considered safe as a food additive by the FDA, according to NaturalStandard.com. Other possible indications for mullein include asthma and bronchitis.
Mullein can be taken in supplement form or as a tea. To make a soothing tea, add 1 tbsp. of dried leaves to one cup of boiling water, steep for 10 minutes and strain. The recommended dose of mullein for treating respiratory conditions is 2-3 cups of tea or 1-2 droppersful of tincture two-to-three times daily.
Horehound is another popular remedy for respiratory complaints. Lozenges and candies made from horehound have been used as a natural cough remedy for centuries. According to AltMD.com, horehound has expectorant properties that make it useful in treating asthma, cough, sore throat, and the common cold. Although its use in cough drops has been banned by the FDA since 1989, European-made lozenges like Ricola that contain the herb are available in the U.S., according to Medline Plus.
Other herbal supplements that may be helpful in maintaining healthy lung function include licorice, slippery elm, and fenugreek.
Vitamins and Minerals
In addition to a daily multivitamin, single nutrients can be taken separately for their ability to protect lung function.
Vitamin E is among the most potent antioxidants of the vitamin world. It works by taking up residence in cell membranes and shielding lung cells from harm caused by pollutants like smog and smoke. According to MotherNature.com, nonsmokers taking vitamin E have half the risk of developing lung cancer compared to those not taking the supplement. The recommended dose of vitamin E supplements is 600 IU daily.
Vitamin C is another vitamin with potent antioxidant properties. According to Harvard.edu, subjects ingesting 200 mg of vitamin C daily scored better on lung capacity tests than those taking higher or lower doses of the supplement. While citrus fruits are an excellent source of vitamin C, acerola cherries and guavas are the best food source of the vitamin, according to NutritionData.com.
Other nutrients with potential lung strengthening properties include vitamin A, vitamin D, and selenium.
Safety Precautions
Herbs and supplements can change the way certain medications affect the body. To avoid unwanted interactions, talk to your doctor before adding a supplement to your lung health regimen.
