Sutter's mantra is weed and feed, or cleanse and build. If you go down that road he would probably not recommend any strict vegan diet.
1)Should i take them together for the best results and minimum Die-Off??
no, one at a time, at least until you figure out what's what. Humaworm is probably not as good as sourcing local herbs, or high dose of raw garlic.
2)If i do need to take them together,
When i need to take my HUMAWORM pills and the Oxypowder pills?
see above. empty stomach is best
3)After i finish the " parasite Cleanse"
i want to start doing Liver Flush,
Is there a certain time i need to wait before i start the Liver Flush?
The idea that there is an order to things was put forth by Hulda Clark . Read her books, then decide for yourself. If parasites are a big part of your liver pathology then some parasite cleansing will probably help to get better Liver Flush results, but it's all individual.
4)I heard that the herbs stays in your system even after you finish the HUMAWORM,
Everything you take in has effect afterward, not just herbs. Don't worry about this, it's the least of things to worry about.
