Jaboticaba (Myrciaria cauliflora) is a fruit native to Brazil and has a long history of use in traditional South American medicine. It is consumed fresh or used in folk remedies for a variety of ailments, including respiratory issues that may involve the mucus membranes. The traditional use of Jaboticaba for supporting the mucus membranes, particularly in the throat and mouth, is primarily based on anecdotal evidence and ethnobotanical reports. Some traditional uses include gargling or consuming preparations made from the fruit to soothe sore throats or mouth inflammations, which are conditions involving the mucus membranes.

Scientifically, Jaboticaba is known to be rich in anthocyanins and other polyphenols, compounds with antioxidant and anti-inflammatory properties. While these compounds theoretically could benefit mucus membrane health by reducing inflammation or oxidative stress, there is currently a lack of direct clinical research or robust preclinical studies specifically evaluating Jaboticaba’s effects on the mucus membranes. Therefore, while there is a traditional basis for its use in this context, scientific validation remains limited, and most available evidence is indirect or extrapolated from its general anti-inflammatory properties.

In summary, Jaboticaba’s use to support the mucus membranes is rooted in traditional practices, with a low-to-moderate level of supporting evidence, and lacks direct scientific validation at this time.
