雷丸含蛋白酶（雷丸素），能水解绦虫体壁蛋白，使虫体破坏死亡。加热可使酶失活，故不宜煎服。
Omphalia contains a protease (leiwan protease) that hydrolyzes tapeworm integument protein, causing parasite destruction. Heat inactivates the enzyme, so decoction is contraindicated.
《中国药典》收载雷丸，注明不宜入汤剂。
Chinese Pharmacopoeia lists Leiwan with a note against decoction.
