Wingless Cockroach Classic Formulas

Primary Actions

Breaks blood stasis and dissipates long-standing masses - Zhe Chong is the classical name most closely associated with severe, chronic, and fixed stasis disorders in the old formula literature.
Relieves pain from congealed blood obstruction - this includes menstrual pain, postpartum lower-abdominal pain, and chronic fullness or hardness from old stasis.
Supports recovery after trauma and fracture - like Tu Bie Chong, the classical Zhe Chong lineage is also valued for helping restore continuity after injury.

Da Huang Zhe Chong Wan - the signature classical formula carrying the Zhe Chong name and one of the strongest examples of stasis-breaking formula design.
Bie Jia Jian Wan - chronic accumulation and mass-dispersing formula logic in which deep stasis and hardness are central concerns.
Trauma formulas containing Zhe Chong with blood-moving and bone-repair herbs - later practical extensions of the same stasis-breaking identity.

TCM Wiki specifically frames Zhe Chong through chronic consumptive disease with blood stasis, amenorrhea, abdominal fullness, and Da Huang Zhe Chong Wan from the Jin Kui Yao Lue.
The classical formula tradition therefore gives Zhe Chong a slightly more canonical, text-anchored feel than the more colloquial Tu Bie Chong name, even though they are not meaningfully separate medicinals here.
This record should be read as a classical-name variant within the same medicinal lineage, not as a second unrelated 'cockroach' herb.
