Rating (out of 5): 2

Flowering quince (Chaenomeles speciosa) has a long history of use in traditional East Asian medicine, particularly in Chinese and Korean herbal systems. In these traditions, the fruit of flowering quince—often referred to as "mu gua"—is believed to have properties that help regulate the digestive system. It is commonly used in herbal formulations to treat symptoms such as gas, bloating, and abdominal discomfort. The traditional rationale is that quince fruit is thought to "harmonize the stomach," "move qi" (vital energy), and resolve "dampness," concepts rooted in Traditional Chinese Medicine (TCM) theory rather than modern biomedical science.

In terms of scientific evidence, the support is limited. Some laboratory studies have identified anti-inflammatory and antioxidant compounds in flowering quince, and animal studies have hinted at possible gastrointestinal benefits, such as spasmolytic activity, which could theoretically help with bloating or cramping. However, these findings are preliminary and do not directly support its use for gas and bloating in humans. There are no large, high-quality clinical trials that specifically validate its efficacy for these symptoms.

In summary, the use of flowering quince for gas and bloating is primarily justified by traditional use. While there are plausible mechanisms and some preliminary research, robust scientific validation is lacking, and the evidence remains modest.
