Known in TCM as Wu Mei (乌梅), this sour and astringent, neutral herb enters the Liver, Spleen, Lung, and Large Intestine. Traditionally, it astringes the Lung and stops chronic cough, especially when prolonged leakage and irritation need containment rather than stronger dispersing herbs, most often applied for cough, diarrhea, and nausea. Modern research has identified Organic among its active constituents.

Traditional Use

Primary Actions

  • Astringes the Lung and stops chronic cough, especially when prolonged leakage and irritation need containment rather than stronger dispersing herbs.
  • Astringes the intestines and relieves chronic diarrhea or dysenteric disorders marked by persistent loss.
  • Generates fluids and alleviates thirst when dryness, chronic illness, or summer heat has injured body fluids.
  • Calms roundworms and relieves parasite-related abdominal pain in the classic `Wu Mei Wan` treatment logic.

Secondary Actions

  • Wu Mei is the smoked and processed mume-fruit medicinal, not just an ordinary fresh plum food entry.
  • Its strong sour-astringent nature makes it ideal for leakage and collapse patterns, but inappropriate when the body still needs to vent an acute pathogen.

Classic Formulas

  • Wu Mei Wan ... the defining classical formula for roundworm disorder and mixed cold-heat intestinal presentations.
  • Sour plum drink and fluid-generating traditions ... the familiar thirst-relieving lane of the herb.
  • Astringent chronic-cough or chronic-diarrhea pairings with other leakage-stopping herbs ... the usual containment strategy.

Classical References

  • Traditional herbology describes Wu Mei as sour, astringent, and neutral, entering the Liver, Spleen, Lung, and Large Intestine.
  • Its four classical hallmark actions are stopping cough, stopping diarrhea, generating fluids, and calming roundworms.
  • Because it is strongly restraining, older texts caution against using it too early in external or excess conditions.

Modern Research

Active Compounds

  • Organic acids including citric-acid-rich fractions
  • Phenolic compounds, flavonoids, and benzyl glycosides
  • Processing-related quality markers such as caffeoylquinic-acid derivatives

Studied Effects

  • A 2021 comprehensive review summarized the phytochemical constituents, pharmacological properties, and clinical applications of Prunus mume, the source plant for Wu Mei (PMID 34122104).
  • A 2022 study on Mume Fructus identified anti-inflammatory quality markers and anti-colitis activity, which is especially relevant to Wu Mei's intestinal-use tradition (PMID 35231824).
  • A 2020 review surveyed the anticancer properties of Prunus mume extracts, illustrating the broad modern research interest in this long-used fruit medicine and food material (PMID 31491438).

Safety & Interactions

Contraindications

  • Early-stage exterior disorders that need venting rather than astringing
  • Acute excess diarrhea without chronic leakage

Cautions

  • Wu Mei is strongly sour and astringent, so it can trap an unresolved pathogen if used in the wrong stage of illness.
  • Persistent cough, chronic diarrhea, or suspected parasitic disease should not be self-managed without evaluation.
