Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Apple Cider Vinegar (ACV) is traditionally used as a home remedy for belching, which is often associated with indigestion or mild gastrointestinal discomfort. The historical rationale is based on the belief that belching can be caused by insufficient stomach acid (hypochlorhydria), and that consuming a small amount of diluted vinegar before meals could "acidify" the stomach, thereby improving digestion and reducing gas formation. This idea is rooted in folk medicine and anecdotal reports, rather than rigorous scientific investigation.

Currently, scientific evidence supporting the effectiveness of ACV for belching is minimal. No well-controlled clinical trials specifically evaluate ACV for the treatment of belching or excessive gas. Existing studies on ACV are limited, often low-quality, and tend to focus on other purported health effects, such as blood sugar control or weight management. The few studies that touch on digestive health do not directly address belching or provide robust evidence for this traditional use.

While ACV remains popular in alternative health circles, its efficacy for belching is primarily supported by tradition and anecdote. Medical professionals often caution that, in some individuals, vinegar can actually worsen gastric symptoms, especially in those with acid reflux or sensitive stomachs. Therefore, while ACV is traditionally used to support digestion and reduce belching, scientific validation is lacking.
