The Role of Apple Cider Vinegar in Alleviating Coughs: A Scientific Perspective
Apple cider vinegar (ACV) has been a popular home remedy for various health conditions due to its alleged therapeutic properties. One common claim is its effectiveness in alleviating coughs, but what does the scientific evidence suggest?
Apple cider vinegar contains acetic acid, which exhibits antimicrobial properties. A study published in the Journal of Food Protection (1) found that ACV inhibited the growth of certain bacteria and fungi, suggesting a potential role against respiratory pathogens. However, more research is needed to confirm this effect in humans and specifically for cough relief.
While ACV may help break up mucus due to its acidic nature (2), there is limited evidence supporting its direct role in suppressing coughs. A small study published in the International Journal of Food Sciences and Nutrition (3) found that a syrup made from honey and ACV reduced nighttime cough and improved sleep quality in children with upper respiratory tract infections compared to placebo, but larger studies are needed to confirm these findings.
Despite its potential benefits, it's essential to note that consuming large amounts of ACV can lead to side effects such as erosion of tooth enamel, throat burn, and potential interaction with certain medications (4). Therefore, it's crucial to consult a healthcare provider before using ACV for cough relief, especially for individuals with pre-existing health conditions or those who are pregnant or breastfeeding.
Although some research suggests that apple cider vinegar may have antimicrobial properties and could potentially help break up mucus, evidence supporting its direct role in suppressing coughs is limited. Further studies are required to establish the effectiveness of ACV for treating coughs and to determine safe dosage and administration methods. As with any home remedy, it's essential to consult a healthcare provider before using apple cider vinegar as a treatment for coughs.
