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

  • Traditional herbology describes Lei Wan as slightly bitter, cold, and mildly toxic, entering the Stomach and Large Intestine to expel parasites.
  • Classical cautions explicitly note that the herb should not be decocted because its activity is easily damaged by heat.
