Sweetgum Fruit

Traditional Use

Primary Actions

• Dispels wind and unblocks the channels - Lu Lu Tong is used for bi pain, numbness, joint restriction, and contracture in the limbs.
• Promotes urination and drains dampness - traditional indications include edema, abdominal distension, and damp obstruction.
• Moves blood and opens flow through secondary obstructions - it is also used for amenorrhea, insufficient lactation, sores, and itchy damp skin disorders.

Secondary Actions

• The name Lu Lu Tong suggests opening blocked pathways in multiple directions, which matches its broad traditional use for channel, fluid, and blood obstruction.
• The medicinal part is the dried infructescence of Liquidambar, not the resin or leaf preparations more commonly studied in modern phytochemistry.

Classic Formulas

• Lactation-opening pairings with Wang Bu Liu Xing, Tong Cao, or Chuan Shan Jia - traditional lineages use Lu Lu Tong when breast channels are obstructed.
• Wind-damp obstruction formulas pair Lu Lu Tong with Du Huo, Qiang Huo, Sang Zhi, or similar channel-opening herbs for painful joints and contracture.

Classical References

• TCM Wiki describes Lu Lu Tong as bitter and neutral, entering the Liver and Kidney to dispel wind, dredge the meridians, promote diuresis, and eliminate dampness.
• Traditional sources also note a pregnancy contraindication because the herb moves and opens strongly rather than simply nourishing.
