Synopsis

Source of validity: Traditional
Rating (out of 5): 3

Luo San is a traditional Chinese medicine (TCM) formula, also known as "Luosan" or "Luosan San," primarily composed of Radix Glycyrrhizae (licorice root), Radix Platycodi (balloon flower root), and Gypsum Fibrosum (a mineral source of calcium sulfate). Historically, Luo San has been used in TCM to support the Stomach body system by clearing heat, harmonizing the middle burner (digestive system), and relieving symptoms such as thirst, restlessness, and occasionally gastric discomfort associated with “Stomach heat.”

Evidence for the use of Luo San in supporting the stomach is primarily based on traditional Chinese medical literature, including classical texts and centuries of clinical practice. The formula is thought to "clear heat from the Stomach" and is often used in cases where there is an excess of heat manifesting as symptoms like mouth sores, dry mouth, or burning sensations in the stomach region.

There is limited modern scientific research specifically addressing Luo San’s efficacy for Stomach support, and most evidence remains anecdotal or based on TCM theory rather than rigorous clinical trials. Some component herbs, such as licorice root, have been studied independently and shown to have gastroprotective and anti-inflammatory properties, but these findings cannot be directly attributed to the Luo San formula as a whole. Thus, the evidence for its use remains rooted in tradition rather than confirmed by high-quality scientific studies.
