4) Earth Dragon Peptides (supplement, http://www.nutricology.com, http://www.needs.com)
Earth Dragon is round worm peptides. It causes a shift to the left (cell-mediated immunity), and is believed to be very similar to IL-12. There has been a huge surge in the use of ED peptides to treat Inflammatory Bowel Disease, specifically Crohn's Disease. One professor at UNC treats all his Crohn's Disease patients with Earth Dragon. It is very non-toxic and safe. This is a good choice for those who want to balance their immune system and also have bowel problems. Earth Dragon is about $36 for 150 caps. The dose is two a day.
