Traditional Use

Primary Actions

  • Clears Heat and benefits the Lung - used in Tibetan and regional minority-medicine traditions for Lung Heat, cough, and hot inflammatory respiratory disorders.
  • Stops cough and supports recovery from hot lung disease - extended to pediatric pneumonia, irritative cough, and feverish pulmonary conditions in traditional formula use.
  • Assists wound healing and retreats jaundice - a lesser but recurring traditional role in ethnic-medicine references for hot sores, tissue injury, and jaundice patterns.

Secondary Actions

  • Shi Hui Hua belongs more to Tibetan and minority-medicine formula traditions than to mainstream single-herb Han TCM dispensing.
  • It is usually powdered and incorporated into compound preparations rather than featured as a famous standalone decoction herb.

Classic Formulas

  • Jiu Wei Shi Hui Hua San (九味石灰华散) - Tibetan formula tradition used for pediatric pneumonia, high fever, agitation, and cough in hot lung disorders.
  • Ba Wei Shi Hui Hua Wan (八味石灰华丸) - regional Tibetan formula line used for heat-type edema, cough, wheezing, oliguria, and weakness with fluid retention.
  • Shi Hui Hua with safflower, terminalia fruit, and aromatic spices - a recurring ethnic-medicine combination pattern for clearing Heat while supporting the Lung and moving constrained pathology.

Classical References

  • Chinese encyclopedia and regional Chinese herb references identify Shi Hui Hua as a characteristic Tibetan mineral medicinal rather than a mainstream Han pharmacopoeia decoction herb.
  • Traditional summaries consistently describe it as slightly sweet and cool, with the core actions of clearing Heat and benefiting the Lung; some regional references also add wound-healing and jaundice-relieving uses.
  • IMPORT NOTE: the source XLSX supplied the Latin 'Calx Pulveratum', which is too generic and can suggest powdered lime. Tibetan materia medica references instead identify this drug as calciosinti, a calcium-carbonate-rich tufa or travertine material. This record follows the Tibetan medicinal identity rather than quicklime or caustic construction lime.

Modern Research

Active Compounds

  • Calcium carbonate (CaCO3) - the dominant mineral component of medicinal calcareous tufa
  • Calcite and related carbonate mineral phases - the main crystalline matrix of the drug
  • Trace magnesium-containing carbonates and silicate impurities - minor natural mineral contributors that vary by deposit source
  • Porous sedimentary mineral matrix - a physical rather than phytochemical feature relevant to powdering and traditional processing

Safety & Interactions

Contraindications

  • Patterns without Heat, Lung irritation, or jaundice-type indications
  • Unsupervised substitution with caustic lime or non-medicinal mineral powders

Cautions

  • Because the historical naming overlaps with broader lime terminology, authenticated medicinal material is essential; Shi Hui Hua should not be confused with industrial lime products
  • Dedicated modern safety literature on this standalone Tibetan mineral drug is sparse, so internal use should remain practitioner-guided
  • Mineral medicines can vary in impurity burden by source deposit, making quality control important
  • MSK page not found - drug interaction data not available from Memorial Sloan Kettering integrative medicine database
