About This Herb*
Traditional Chinese Medicine background and properties
Herb Description*
Dandelion is one of the most versatile Heat-clearing herbs in Chinese medicine, prized especially for treating breast infections, skin abscesses, and urinary tract infections. It clears internal Heat and inflammation, reduces swelling, and supports liver and urinary function. Despite its humble reputation as a common weed, it has been a valued medicinal plant for over a thousand years.

Main Actions*
- Clears Heat and Resolves Toxicity
- Disperses Swelling and Dissipates Nodules
- Promotes Urination and Relieves Stranguria
- Clears Liver Heat and Brightens the Eyes
How These Actions Work*
'Clears Heat and resolves Toxin' means this herb directly counteracts inflammatory, infectious conditions that TCM categorizes as Heat-Toxin. In practical terms, this covers acute infections with redness, swelling, heat, and pain, such as skin abscesses, boils, breast infections, and sore throats. Pú Gōng Yīng's cold nature cools the Heat, while its bitter taste drives the pathogen downward and out. It is considered the foremost herb for breast abscess (mastitis) and is also widely used for any sore or skin infection with prominent Heat signs.
'Reduces swelling and disperses nodules' means the herb can break up localized accumulations of pathological material, whether these present as inflamed lumps, swollen lymph nodes, or hard masses. This action goes beyond simply clearing Heat: it actively resolves the physical congestion. This is why it is used for conditions like lymphadenitis (swollen lymph nodes) and scrofula, often paired with Xià Kū Cǎo.
'Promotes urination and unblocks painful urinary dysfunction' refers to its mild diuretic effect, which helps flush Damp-Heat from the urinary system. This makes it useful for urinary tract infections with burning, painful, difficult urination and for Damp-Heat jaundice. It is not as strongly diuretic as dedicated water-draining herbs, but adds urinary benefit when Heat-Toxin patterns involve the Lower Burner.
'Clears Liver Heat and brightens the eyes' reflects the herb's affinity for the Liver channel. Since TCM teaches that the Liver 'opens to the eyes,' clearing Liver Heat directly benefits red, swollen, painful eyes. This action is used for acute conjunctivitis and other inflammatory eye conditions driven by Liver Fire.
Patterns Addressed*
In TCM, symptoms cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Pu Gong Ying is traditionally associated with these specific patterns.
The following describes this herb's classification within Traditional Chinese Medicine theory and is provided for educational purposes only.
Why Pu Gong Ying addresses this pattern
Pú Gōng Yīng is bitter and cold, entering the Liver and Stomach channels. Its bitter taste descends and drains, while its cold nature directly clears Heat and resolves Fire Toxin. This makes it highly effective for Toxic-Heat patterns where pathogenic Heat accumulates and congeals into painful, red, swollen sores and abscesses. It is considered the key herb for breast abscess (mastitis) because the breast is governed by the Stomach channel (breast tissue) and Liver channel (nipple), both of which this herb enters directly. The herb both clears the toxic Heat internally and disperses the local swelling and stagnation.
A practitioner would look for one or more of these signs
Red, swollen, painful breast lumps, especially early-stage acute mastitis
Skin boils, carbuncles, and furuncles with redness and heat
Internal abscesses including lung or intestinal abscess
Sore, red, swollen throat from Heat-Toxin
Why Pu Gong Ying addresses this pattern
Pú Gōng Yīng enters the Liver channel and is cold in nature, giving it a strong ability to clear Liver Fire. When Liver Fire flares upward, it causes red, swollen, painful eyes and irritability. The herb's bitter-cold properties drain excess Liver Heat downward, relieving the upward flaring of Fire. Classical texts note it is excellent for treating eye diseases caused by Liver Heat. The Ben Cao Qiu Zhen states that Pú Gōng Yīng enters the Liver and Stomach channels to cool the Blood and resolve Heat.
A practitioner would look for one or more of these signs
Red, swollen, painful eyes from Liver Fire flaring upward
Eye pain and inflammation with a burning sensation
Headache associated with Liver Fire rising
Why Pu Gong Ying addresses this pattern
Pú Gōng Yīng's sweet taste gently clears and resolves, while its bitter-cold nature drains Dampness and Heat downward through the urinary tract. This combination of clearing Heat and promoting urination makes it effective for Damp-Heat lodged in the Lower Burner, where it causes painful, difficult urination (hot strangury) or jaundice. Its ability to benefit the Stomach channel also connects to its use for Damp-Heat jaundice, since the Stomach and Spleen are central to Dampness metabolism.
A practitioner would look for one or more of these signs
Painful, burning urination with dark or scanty urine
Yellow discoloration of skin and eyes from Damp-Heat
Difficulty urinating with a sense of heat
