This is a modern patent formula, as the Chinese name suggests (Pill Benefiting Water and Expelling Stones), designed to reduce and flush out stones and "sand" from the urinary tract, being effective for stones up to 8 mm.
The principle of its action is to clear damp-heat, the pathology that causes the formation of stones (not only in the bladder but also in the bile ducts). The most common mechanism is the formation of dampness in the area of the middle burner, which then descends, where it overheats due to stagnation or other causes – and damp-heat is born. It manifests as problems with urination and lower abdominal pain, as we know, for example, from cystitis, or which may have a paroxysmal character. The second possible scenario is the formation of sand and stones. Of course, insufficient fluid intake or a high proportion of hot, fatty, or spicy products in the diet can also contribute to this.
Lysimachia, Pyrrosia, and Mallow can act directly on damp-heat, i.e., also on urinary stones, and dissolve them. Honeysuckle, Cynanchum, and Dianthus relieve pain, as does Mallow. All these herbs also promote urination, which is further aided by Plantago seed, as well as Talcum – to make it "slide nicely". Liquorice harmonises the herbs in the mixture and also has a positive effect on the urinary and reproductive systems. As the stones shrink, the pain subsides. And we have a much better chance that they will leave naturally and we will find definitive relief.
The mixture may potentiate the effect of conventional medicine diuretics (e.g., furosemide, HCTZ); in that case, use with caution to avoid excessive loss of water and electrolytes.
