Are you following ICUS protocol for strongyloides which is a very effective protocol. i did not take any herbal treatments except de powder food grade for 2 weeks before i had steroids and knew i had strongyloides. i split my ivermectin dose to 2 half doses twice a day and held the meds in my mouth like candy for as long as i can on an empty stomach. i did not drink or eat for 2 hours after the mectin which absorbs into mouth throat and sinuses cutting off the migration path of larvae crawling up throat from lungs. this eliminated for the most part my albendazole headaches. itchy eyes, nose etc . It works very well a trick from farm vet that i shared with another sufferer on this website privately and was notified (thanks) by fellow sufferer that followed my advice.
