About This Herb*
Traditional Chinese Medicine background and properties
Herb Description*
Hai Fu Shi is a mineral substance used in Chinese medicine to clear heat from the lungs and dissolve stubborn, thick phlegm. It can be derived from the skeleton of marine bryozoans or from volcanic pumice stone. It is commonly used for chronic coughs with thick, sticky phlegm, thyroid nodules, and urinary stones.

Main Actions*
- Clears Lung Heat and Transforms Phlegm
- Dissipates Nodules and Softens Hardness
- Promotes Urination and Relieves Stranguria
How These Actions Work*
'Clears Lung heat and transforms phlegm' means Hai Fu Shi helps cool the Lungs when heat has caused phlegm to become thick, sticky, and difficult to cough up. Its salty taste has a natural softening effect that breaks down hardened, old phlegm. This is the herb's primary action and the reason it is classified among the heat-clearing, phlegm-transforming herbs. It is especially suited for chronic, stubborn phlegm that has condensed over time, and for cases where Lung heat causes blood-streaked sputum.
'Softens hardness and dissipates nodules' refers to this herb's ability to address hard lumps and masses formed by the accumulation of phlegm. In TCM, conditions like thyroid nodules (yǐng liú), swollen lymph nodes (luǒ lì), and other firm, palpable swellings are often attributed to phlegm congealing with heat or stagnation. The salty, cold nature of Hai Fu Shi softens these hardened accumulations and helps disperse them.
'Promotes urination and unblocks stranguria' means Hai Fu Shi can help with painful, difficult urination, especially when there are urinary stones (stone stranguria) or blood in the urine (blood stranguria). Classical texts explain that by clearing heat from the Lungs (the 'upper source of water'), it helps restore the normal downward flow of fluids to the Bladder.
Patterns Addressed*
In TCM, symptoms cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Hai Fu Shi 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 Hai Fu Shi addresses this pattern
When heat accumulates in the Lungs and scorches fluids into thick, congealed phlegm, the result is a pattern of coughing with heavy, sticky, yellow sputum that is difficult to expectorate. Hai Fu Shi directly addresses this pathomechanism through its cold nature, which clears Lung heat, and its salty taste, which softens and dissolves hardened, old phlegm. It is particularly valued when phlegm has been accumulating for a long time and has become dense and clumped, or when Lung heat damages the blood vessels of the Lung, causing blood-streaked sputum.
A practitioner would look for one or more of these signs
Chronic cough with thick, sticky, yellow phlegm that is hard to expectorate
Phlegm streaked with blood due to heat damaging Lung vessels
Wheezing and chest tightness from phlegm obstruction
Why Hai Fu Shi addresses this pattern
When phlegm and fire combine, they can give rise to hard nodules and masses in the neck and other areas. Hai Fu Shi's salty, cold nature allows it to both clear the fire component and soften the hardened phlegm that forms these nodular accumulations. Its channel entry into the Lung and Kidney is relevant because the Kidney governs the throat region, and the Lung channel passes through the neck area where goiters and scrofula commonly appear.
A practitioner would look for one or more of these signs
Thyroid nodules or goiter from congealed phlegm-fire
Scrofula or swollen lymph nodes
Why Hai Fu Shi addresses this pattern
In cases of damp-heat accumulating in the Bladder, stones and blood may appear in the urine. Hai Fu Shi addresses this by clearing heat from the upper source of water (the Lungs) and promoting the downward flow of fluids. Its ability to soften hardness also helps with the dissolution of urinary stones. The Kidney channel entry is particularly relevant here, as the Kidney governs the lower urinary tract.
A practitioner would look for one or more of these signs
Painful, difficult urination with possible blood or stones
Urinary calculi (stone stranguria)
