Dung Beetle — Classic Formulas

Qiang Lang · Catharsius molossus

Primary Actions

  • Relieves severe constipation and attacks accumulation - Qiang Lang is a harsh attacking insect medicine historically used for hard focal masses, obstructed bowels, stubborn food accumulation, and repletion patterns that require breaking and purging rather than tonifying.
  • Breaks blood stasis and attacks toxins - classical use extends to hemorrhoidal swelling, chronic sores, nodular abdominal masses, amenorrhea with obstruction, and other hard stagnation patterns in which softer medicinals were considered insufficient.
  • Opens obstruction and calms severe shen disturbance - older texts also mention its use in specialist formulas for epilepsy, mania, or severe internal blockage, though this has never been a common household application.

Classic Formulas

  • Qiang Lang appears in older attacking-accumulation pill traditions for constipation, abdominal masses, and pediatric accumulation disorders.
  • Historical hemorrhoid and toxin-dispersing prescriptions paired Qiang Lang with purgatives and blood-invigorating medicinals when swelling, hardness, or obstruction predominated.
  • Specialist formulas for severe shen disturbance sometimes combined Qiang Lang with other insect, mineral, or toxin-attacking agents, but such use is now largely of historical interest.

Classical Text References

  • Early materia medica such as Shen Nong Ben Cao Jing place Qiang Lang among forceful, lower-grade medicinals used for accumulation, masses, and difficult obstruction rather than for gentle long-term use.
  • Ben Cao Gang Mu and later commentaries preserved its reputation for breaking accumulations, dispersing stasis, and addressing hard or toxic lesions.
  • Its traditional profile is that of a harsh attacking medicine chosen for excess patterns and avoided in weak, pregnant, or fluid-depleted patients.
