That's interesting about the pumpkin seed. I don't know what was in your throat but it seems parasites can be just about anywhere in the body - one reason stool testing is so often in error.
I would have 2 concerns for you. One is that you would think that only pumpkin seed will get rid of parasites. That wasn't true for me, personally, at all, thouogh it is helpful. The other concern is that you might think that you only have the kind of parasite - if you saw any - the kind that are in your throat. Sadly, you and your loved ones probably have various parasites as they are very insidious & apparently universal.
Re the topic of enemas sometimes mentioned below, I am adding a personal feeling of caution about colonics - professionally done high colonic enemas. I have seen them really depleting people's energy, though some really like them. They do flush out a lot of good bacteria & probiotics along with the junk.
There is really no data that I know of to show that good bacteria can be replaced by over the counter supplements, or even things like acidophilus yogurt, kefir etc., after such a highly invasive wash of the intestines. (You can tell if your yogurt or kefir has live probiotics by adding a heaping tbsp. to regular milk, then letting it sit for 8 -16 hours. If itís the real stuff the milk will thicken and give you more yogurt or kefir.) Maybe so, maybe no, but there is new info coming out that low probiotics in the gut can cause things like depression (see Dr. Mercola & Dr. Marsha Campbellís Youtube vid for example) and even possibly things like autism if the mother's probiotics are too low and she doesn't pass enough onto her baby in the birth canal or through her milk.
I'm no expert on any of that, just presenting what I worry may be a potential hazard. Mho.
