According to Cure for All Cancers humans are more infested now than ever before, because we have upset the balance of nature with propolene glycol and other additives to hygiene and facial products etc. and now even in food products. (Propolene glycol is a moisturizing agent. Now it seeme to be pumped into everything. The first time I saw it in food was 1996, in dried coconut. Now if you read the fine print on many supermarket bakery goods and prepackaged frostings, brownie mixes, etc. you will see the propolene glycol, listed.
I won't go into the whole sequence here, on how people get infested with more mammalian parasites, and how this can lead to cancer.
Whoever posted the thing on oregano oil can you post a book reference, link etc.?
