Known in TCM as Huo Xiang Ye (藿香叶), this acrid, slightly warm herb enters the Lung, Spleen, and Stomach. Traditionally, it aromatically transforms dampness and harmonizes the middle - Huo Xiang Ye is used for nausea, poor appetite, abdominal fullness, and damp-turbidity affecting digestion, most often applied for nausea, poor appetite, and diarrhea. Modern research has identified Essential-oil among its active constituents.

Traditional Use

Primary Actions

  • Aromatically transforms dampness and harmonizes the middle - Huo Xiang Ye is used for nausea, poor appetite, abdominal fullness, and damp-turbidity affecting digestion.
  • Releases the exterior and resolves summer-damp - traditional use includes heaviness, mild chills or fever, and digestive upset during humid summer disorders.
  • Stops vomiting and freshens turbidity - the leaf is used when foul taste, chest oppression, and rebellious Stomach qi accompany damp obstruction.

Secondary Actions

  • This page preserves Agastache rugosa leaf as a separate `Huo Xiang Ye` track rather than flattening it into the already-live `Guang Huo Xiang Ye` page for Pogostemon cablin.
  • Agastache leaf is lighter and more explicitly species-sensitive than the broad generic `Huo Xiang` label often seen in commerce.

Classic Formulas

  • Huo Xiang Zheng Qi San - classic summer-damp and digestive-turbidity formula family in which aromatic Huo Xiang leads the opening strategy.
  • Huo Xiang with Pei Lan and Sha Ren - pairing style for turbid dampness, nausea, and poor appetite.
  • Huo Xiang with Ban Xia or Zhu Ru - traditional logic when vomiting and phlegm-turbidity are prominent.

Classical References

  • Traditional references describe Huo Xiang Ye as acrid and slightly warm, entering the Lung, Spleen, and Stomach to transform dampness, stop vomiting, and resolve summer-damp.
  • Chinese herbology has long acknowledged ambiguity around `Huo Xiang`, which can refer to Agastache rugosa or Pogostemon cablin depending on source tradition.
  • This page keeps the Agastache medicinal-leaf identity explicit to avoid future collapse of the two aromatic leaf tracks.

Modern Research

Active Compounds

  • Essential-oil constituents such as estragole and methyleugenol chemotype-related compounds - major aromatic markers of Agastache rugosa
  • Flavonoid and phenylpropanoid glycosides - supportive anti-inflammatory and antioxidant constituents
  • Leaf and aerial-part terpenoid fractions - bioactive compounds relevant to damp-transforming and antimicrobial interpretation

Studied Effects

  • A 2023 review summarized phytochemistry and therapeutic properties across Agastache species and noted that A. rugosa is the main East Asian medicinal representative, with anti-inflammatory, antioxidant, antimicrobial, and cardiometabolic activity reported across the literature (PMID 37631149).
  • A 2019 study isolated constituents from the aerial parts of Agastache rugosa that inhibited prostaglandin E2 production in LPS-treated macrophages, supporting the herb's modern anti-inflammatory plausibility (PMID 31747281).
  • A 2003 analysis showed clear differences in essential-oil composition between Agastache rugosa stems, leaves, and flowers, reinforcing that the leaf record should be treated as a distinct aromatic medicinal part rather than generic whole-herb material (PMID 12575134).

Safety & Interactions

Contraindications

  • Marked yin deficiency dryness without damp turbidity

Cautions

  • Species confusion with Pogostemon cablin remains common under the `Huo Xiang` label, so source identity matters for both tradition and chemistry.
  • Concentrated essential-oil products are much stronger than ordinary leaf decoctions and should not be treated as equivalent.
  • MSK page not found - drug interaction data not available from Memorial Sloan Kettering integrative medicine database
