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
