He's done a lot with complicated systemic infections.
Adding D3 and calcium makes the Albendazole/Praziquantel combination more effective at lower doses. DEC (Diethylcarbamazine) and piperazine he claims are very helpful. Levimasole, too. His book describes lots of supplements/vitamins that are also either effective or useful adjuncts.
It's a tough read, but there is a lot of good information.
If your infection is systemic, you have to be real careful to emphasize systemic meds and herbs. An herb or med that only works in the gut, may simply drive the parasites deeper into your body.
I've not tried anything beyond the usual herbs and praziquantel/ivermectin/albendazole/niclosamide yet, but hope to try DEC, piperazine, D3 soon. Just having trouble finding them in Thailand.
