Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Oak (Quercus species), particularly the bark, has a long history of traditional use in folk medicine for treating ulcers, especially those affecting the mouth and gastrointestinal tract. Historical records from European herbal medicine cite oak bark infusions, decoctions, or powders as remedies for peptic ulcers, gastric irritation, and diarrhea. The rationale for this use is primarily due to the high content of tannins in oak, which are astringent polyphenolic compounds known to have anti-inflammatory and antimicrobial properties. Tannins can help contract and protect mucous membranes, potentially reducing ulceration and aiding tissue repair.

However, scientific evidence directly validating the efficacy of oak for treating ulcers in humans is limited. Most studies have focused on the antimicrobial and astringent actions of oak extracts in vitro or in animal models rather than on controlled clinical trials in ulcer patients. There is some preclinical evidence that oak tannins can inhibit the growth of Helicobacter pylori, a bacterium implicated in peptic ulcer disease, and may reduce inflammation in animal models of gastric injury. Nonetheless, these findings have not been robustly translated into clinical practice, and there are concerns regarding potential toxicity and side effects of tannin-rich preparations if consumed in large amounts or over extended periods.

In summary, the use of oak for ulcers is primarily supported by traditional medicine, with limited scientific research providing only preliminary support.
