Killing roundworms with Tamanu oil

I've been feeling lots of different things happening in my rectum. At times it feels like an itchy bug bite, other times just foreign body movement, but mostly it feels like something is attaching itself to my lining. Also, I'm feeling an irritating and slightly uncomfortable nawing higher up in my intestines. And for the last couple months I feel constipated, like there is a "fullness" in rectum even when I typically pass normal soft-formed stools. Once in a while my stool looks much thinner like there is actually blockage.

I'm currently not taking any herbs or RX. I tried Hulda Clark 's intensive Black-Walnut , Wormwood , clove protocol with highest dosages with no improvement. I also tried Markus Rothkranz's " parasite Free" with no improvement. I stopped taking herbs because NOTHING was coming out and I just feel them throughout my body and brain even more, nawing and causing pains, vibrating, thumping, etc.

I've been experimenting lately by injecting about 1 tsp. tamanu oil (AKA Kamani oil) rectally with an oral syringe. It acts like a laxative and it's hard to hold it but If I hold it in for atleast 30 minutes and then expel there will be an off-white colored mucus. The longer I hold it, the more mucus comes out. (I'm guessing it's mucus anyway). And with the next bowel movement I will ALWAYS see atleast one dead roundworm in my stool. Whatever it is, it has one end that is wider.

Been trying to find a study or something about taking Tamanu oil orally but coming up short. I want to try since I've had continuous success with it rectally but I'm so scared of what might happen. Almost given up trying to rid them naturally. I'm open to opinions and suggestions!!
