Apple Cider Vinegar for Colds

Apple cider vinegar is produced from the fermented, unstrained juice of crushed apples. It’s acidic and emits a strong aroma reminiscent of aged wine.

Many people turn to it as a home treatment for colds. Scientists are still investigating how it might ease symptoms and whether certain people might not benefit from it.

Some individuals use apple cider vinegar as an expectorant to help break up nasal and chest congestion, while others take it hoping to strengthen their immune response.

Potential perks of apple cider vinegar for colds

Unfiltered apple cider vinegar frequently contains the “mother,” a colony of yeast and beneficial bacteria that act as probiotics. A 2018 review indicated that probiotics can enhance immune function and may help protect against influenza-like respiratory illnesses and the common cold (1).

Additionally, vinegar includes polyphenols — antioxidant compounds common in plant foods — that might help alleviate cold symptoms (2, 3, 4).

Common apple cider vinegar remedies for a cold

Using vinegar for chronic coughs has roots in remedies from the late 19th century. Modern variations often mix apple cider vinegar with honey (5).

Throat rub made with apple cider vinegar

Some people apply apple cider vinegar to the throat area and around the sinuses. Its sharp scent may help free up congestion and make breathing easier while the body combats a viral or bacterial infection.

Apple cider vinegar supplements

You can buy apple cider vinegar capsules online or in stores, but remember that dietary supplements aren’t regulated by the Food and Drug Administration. Products may contain ingredients not listed on the label.

A 2005 analysis of eight different apple cider vinegar supplements revealed inaccurate, inconsistent labeling and claims lacking evidence. Researchers even questioned whether apple cider vinegar was present in some pills (6).

Possible side effects and hazards

Like other vinegars, apple cider vinegar is acidic. Its acidity can irritate the stomach lining and worsen acid reflux. It should be diluted before drinking.

Those with stomach ulcers or GERD might want to avoid using apple cider vinegar because of this (7).

Apple cider vinegar has also been linked to esophageal damage and dental erosion. After consuming any apple cider vinegar solution, rinse your mouth with water to help protect tooth enamel (7).

The American Academy of Pediatrics has not issued an official position on apple cider vinegar, according to a CNN report (8).

If you’re thinking about giving apple cider vinegar to a child for a sore throat, congestion, or any other reason, consult their pediatrician or another medical professional first.

Final thoughts

Apple cider vinegar is a folk remedy many people trust, but conclusive research showing it reliably treats colds is limited. For most adults, trying apple cider vinegar is relatively low-cost and low-risk for mild symptom relief.

If your cold symptoms are serious or you experience any of the following, avoid home treatment and seek medical care:

• a cough that won’t go away
• a fever lasting more than 48 hours
• dizziness
• nausea

Contact your healthcare provider for appropriate treatment options if your symptoms persist or worsen. They can help determine what’s causing your symptoms and recommend the best plan of care.
