Pumpkin oil for flush?

I'm sure this question has been asked before but, I wanted to know if you can use pumpkin oil for a liver flush? Or will I be getting to much omegas at one time and get side affects from it? I've been taking it (1 tbs) with freshly juiced pineapple
juice twice a day and I've noticed that I get a little dizzy and a little nauseous afterwards. It seems to go away after about 5 mins. Is this normal?
The reason I wanted to try the pumpkin oil instead is to paralize the large flukes or Tapeworm i can feel in my liver.
Any advise would be appreciated!
