Allium species, such as garlic (Allium sativum) and onion (Allium cepa), have a long history of use in traditional medicine systems across various cultures, including Ayurveda, Traditional Chinese Medicine, and European folk medicine. They are primarily used to address digestive complaints, which sometimes encompass symptoms like belching (eructation), bloating, flatulence, and indigestion. The rationale for their use is based on their reputed carminative properties—substances believed to help expel gas from the digestive tract—and their ability to stimulate appetite and digestive secretions. While garlic and onion are frequently mentioned in traditional herbal texts as remedies for digestive discomfort, direct historical references specifically targeting "belching" are less common; instead, the use is more broadly for "indigestion" or "dyspepsia," which may involve belching as a symptom. There is some overlap in traditional herbalism between treating flatulence, bloating, and belching, and Allium species are commonly listed for such uses. However, modern scientific validation for Allium's effectiveness specifically in reducing belching is limited. Most contemporary studies focus on other potential health benefits of Allium species, such as cardiovascular or antimicrobial effects, rather than gastrointestinal symptoms like belching. Therefore, the evidence for this use is primarily traditional, and current clinical evidence is insufficient to strongly support its efficacy for this particular symptom.
