Rating (out of 5): 2

Sharp-leaf galangal (Alpinia officinarum), also known as lesser galangal, has a long history in traditional medicine systems, particularly in Southeast Asia and China. Traditional healers have used sharp-leaf galangal rhizomes to address digestive ailments, including indigestion, flatulence, and stomach discomfort, which are sometimes associated with gastric or peptic ulcer symptoms. The rationale in traditional use is based on its warming and carminative properties, believed to soothe the stomach and support gastrointestinal health.

However, the direct use of sharp-leaf galangal specifically for treating or supporting ulcers is less well-documented than its general application for digestive health. Some traditional texts and ethnobotanical surveys mention its use for "ulcers" or "sores," but these references can be ambiguous and may not always refer to peptic or gastric ulcers as understood in modern medicine.

Scientific evidence for sharp-leaf galangal's anti-ulcer effects is limited. A few laboratory studies have investigated the anti-inflammatory and antioxidant properties of Alpinia officinarum extracts, and some animal models suggest a potential for reducing gastric lesions, but the data are preliminary and not robust. There are no large-scale clinical trials or comprehensive pharmacological studies confirming its efficacy for ulcer treatment in humans. Thus, while the use of sharp-leaf galangal for ulcers has a traditional basis, scientific validation is minimal and the evidence level is low.
