Even taking Bing Lang Wan (formula) did very little, only large dosages of Bing Lang worked, this pretty much limits it to round worms.
Only two species require VERY large dosage, Ascaris and Echinococcus. Add to that; I grew up in an area which was later labeled as Fox Echinococcus epidemic area.
Bing Lang is on the restricted list of herbs and almost impossible to get here right now. After all if you chewed a few pounds of Betel Nut for 12 years you have a statistically higher rate of mouth cancer so the government is here to protect us. Wonder what chewing large amount of Sugar for 12 years does…
