Stone Formula targets damp-heat accumulation in the lower burner. The buildup of pathogenic factors in this region leads to shi ling, "stony, painful urinary dysfunction" and the formation of urinary tract calculus. Stone formula targets calculi occurring in the kidneys, ureters, bladder or urethra. It shrinks and breaks down larger stones and eliminates small ones. Stone formula smoothes the jagged edges of stones broken down by lithotripsy and reduces complications from this procedure.

By promoting peristalsis in the urinary tract, it helps ease the passage of smaller stones and prevents new stones from forming or recurring. In TCM terms, Stone formula is indicated for damp-heat in the lower jiao accumulating to form stones. Integration of Chinese medicine and western medicine would be a good choice for this disease. When treating urinary stones, Chinese doctors will take everything into consideration, including the following conditons.

1. Poor nutrition
2. Long term use of urinary catheters
3. Having frequent bladder infections.
4. Inadequate intake of fluids, especially water
5. Having a urinary tract infection
6. Enlarged prostate gland in men
