Thunder Ball … Classic Formulas
Lei Wan · Omphalia lapidescens
Primary Actions
- Expels intestinal parasites ... Lei Wan is especially associated with tapeworm and other helminthic disease rather than with broad tonic use.
- Relieves parasite-related abdominal discomfort ... older use includes abdominal pain, poor appetite, and bowel disturbance when worms are the true driver.
- Preserves a fungal-sclerotium medicine distinct from plant antiparasitic herbs ... this page should stay specimen-forward and restrained.
Classic Formulas
- Zhui Chong Wan ... classic parasite-expelling formula where Lei Wan reinforces elimination of intestinal worms.
- Single-herb powder use for tapeworm ... one of the clearest traditional administration routes for Lei Wan.
- Combined pill or powder use with Bing Lang, Qian Niu Zi, or Da Huang ... traditional strategies when stronger expulsion is needed.
Classical Text References

- Classical cautions explicitly note that the herb should not be decocted because its activity is easily damaged by heat.
