Known in TCM as Pu Gong Ying (蒲公英), this bitter and sweet, cold herb enters the Liver, Stomach, and Lung. Traditionally, it clears heat and resolves toxicity - Pu Gong Ying is a major herb for boils, furuncles, breast abscess, and other hot toxic swellings, whether superficial or internal, most often applied for breast abscess, mastitis, and abscess. Modern research has identified Taraxasterol among its active constituents.

Traditional Use

Primary Actions

  • Clears heat and resolves toxicity - Pu Gong Ying is a major herb for boils, furuncles, breast abscess, and other hot toxic swellings, whether superficial or internal.
  • Reduces breast swelling and supports resolution of mammary abscess - it is one of the best-known herbs for painful red breast lumps, mastitis-type presentations, and nodular heat toxicity in the breast.
  • Clears fire and toxicity from the throat, eyes, and gums - it is used for sore throat, red painful eyes, and gum swelling when heat or toxin rises upward.
  • Clears damp-heat and promotes urination - traditional use also includes painful urinary difficulty, damp-heat jaundice, and heat-type diarrhea or dysentery.

Secondary Actions

  • Pu Gong Ying is stronger at heat-toxin and abscess work than many ordinary food-grade dandelion preparations, even though it remains gentler on the Stomach than some bitter detoxifying herbs.
  • Fresh juice, thick decoction, and topical applications all appear in traditional practice, especially for breast abscess, boils, and venomous bites.

Classic Formulas

  • Wu Wei Xiao Du Yin - Pu Gong Ying is one of the key toxin-resolving herbs in this classic formula for boils, carbuncles, and early suppurative swellings.
  • Pu Gong Ying with Gua Lou and Jin Yin Hua - a classic breast-abscess and nodulation-clearing strategy.
  • Pu Gong Ying with Yin Chen, Zhi Zi, and Da Huang - a damp-heat clearing combination for jaundice and lower-burner heat accumulation.

Classical References

  • Traditional texts describe Pu Gong Ying as bitter, sweet, and cold, entering the Liver, Stomach, and Lung to clear heat, remove toxicity, reduce abscesses, and drain damp-heat.
  • Its special reputation for breast abscess comes from its ability to clear heat-toxin from the Liver and Stomach while also helping the breast tissue soften and discharge.
  • Because Pu Gong Ying also clears the throat, eyes, gums, and urinary tract, it is broader than a simple skin-detox herb.

Modern Research

Active Compounds

  • Taraxasterol - a major triterpenoid associated with anti-inflammatory and metabolic studies
  • Chicoric acid and chlorogenic acid - prominent phenolic acids with antioxidant and anti-inflammatory interest
  • Flavonoids such as luteolin derivatives - relevant to anti-inflammatory and antioxidant activity
  • Polysaccharides - immunomodulatory fractions increasingly studied in Taraxacum mongolicum

Studied Effects

  • A 2023 review summarized the chemical constituents and pharmacologic effects of the Taraxacum genus and confirms why Pu Gong Ying remains one of the most widely studied heat-clearing medicinal plants (PMID 37446683).
  • In a mouse model of Staphylococcus aureus mastitis, Taraxacum mongolicum reduced inflammatory signaling through TLR2, NF-kappaB, and MAPK pathways, which strongly aligns with the herb's traditional use for mastitis and breast abscess (PMID 33212175).
  • An antioxidant-identification study characterized multiple active radical-scavenging constituents from Taraxacum mongolicum, supporting the herb's modern anti-inflammatory and protective profile (PMID 18801488).

Safety & Interactions

Contraindications

  • Known allergy to dandelion or other Asteraceae plants
  • Use of high-dose extracts without attention to blood sugar or diuretic effects

Cautions

  • Memorial Sloan Kettering notes that dandelion can cause heartburn, stomach upset, rash, mild diarrhea, and low blood sugar in susceptible users.
  • MSK also notes preclinical estrogenic activity and advises caution with concentrated supplement use when hormone sensitivity is a concern.
  • Large amounts of tea or extract are more likely to cause side effects or medication interactions than ordinary food use.

Drug Interactions

  • Diuretics - dandelion may have additive diuretic effects
  • Hypoglycemic medications - dandelion may have additive blood-sugar-lowering effects
  • CYP1A2 and CYP3A4 substrate drugs - dandelion may alter metabolism and blood levels of these medications
  • UGT substrate drugs - animal studies suggest dandelion may affect glucuronidation pathways
  • Immunosuppressants metabolized through CYP3A4 - a case report linked toxic drug levels to tea containing dandelion
