Traditional Use
Primary Actions
- Dispels wind-damp and relaxes the channels - Lu Ying is traditionally used for rheumatic pain, lower-back and leg pain, and stiffness that worsens with dampness.
- Promotes urination and reduces swelling - classical and regional sources use it for edema, swollen feet, and damp accumulation affecting the limbs.
- Activates blood and reduces traumatic swelling - folk and materia medica traditions extend its use to bruises, fractures, postpartum lochia retention, and painful swelling after injury.
- Clears toxic swelling externally - washes, poultices, and powders are used for itching rashes, erysipelas-type redness, carbuncles, and inflamed sores.
Secondary Actions
- Despite the historical slug, Lu Ying is a stems-and-leaves medicine rather than a flower drug, and the whole identity of the material matters for correct use.
- It sits closer to regional damp-trauma practice than to the cold-and-flu reputation many English speakers associate with European elderflower.
Classic Formulas
- Lu Ying with Yi Yi Ren or other damp-draining herbs - regional strategy for edema, damp arthralgia, and swollen painful legs.
- Lu Ying with Dang Gui, Chuan Xiong, or Ru Xiang - folk trauma combinations for bruises, fractures, or postpartum stagnant pain.
- Topical Lu Ying washes or poultices - traditional external-use approach for urticaria, erysipelas, toxic swelling, and itchy wind-damp skin eruptions.
Classical References
- ShennongAlpha and related materia medica summaries describe Lu Ying as the stems and leaves of Sambucus chinensis used to dispel wind, promote diuresis, relax tendons, and activate blood.
- Older discussions cite it for wind-damp arthralgia, edema, bruises, lochia retention, and itchy rashes, showing a broad pattern of damp-swelling and trauma use.
- Later regional herb manuals also extend Lu Ying to hepatitis, dysentery, tonsillitis, mastitis, burns, and fractures, especially in external or folk settings.
Modern Research
Active Compounds
- Flavonoids and phenolic acids - major constituents repeatedly reported in Sambucus chinensis analyses
- Ursolic acid and related triterpenes - important markers in Lu Ying extract studies
- Chlorogenic acid - a recurring phenolic constituent in quality-control work
- Tannins and broader polyphenol fractions - likely contributors to anti-inflammatory and astringent effects
Studied Effects
- A mouse study reported hepatoprotective activity from an active fraction of Sambucus chinensis against CCl4-induced hepatitis injury, supporting part of the herb's regional liver-swelling reputation (PMID 19112906).
- A pharmacokinetic study tracked ursolic acid after administration of a Lu Ying preparation, showing that modern extract research has focused on measurable triterpene markers rather than only crude decoction tradition (PMID 15930819).
- A chemistry-and-pharmacology review summarized older evidence for analgesic, anti-inflammatory, diuretic, and hepatoprotective effects, but also highlighted how much of the evidence remains preclinical and dated (PMID 15719672).

Safety & Interactions
Contraindications
- Pregnancy
- Very weak constitutions without dampness, swelling, trauma, or wind-damp obstruction
Cautions
- Traditional sources distinguish the medicinal stems and leaves from the seeds, which contain cyanogenic glycosides and should not be treated casually.
- Older toxicology notes describe restlessness, tremor, and convulsions at extreme experimental doses, so concentrated extracts deserve more caution than ordinary decoctions.
