Rahi, I had a doctor about 12 years ago who diagnosed me with candida. She put me on the candida diet and some other protocol which I don't quite remember. But 35% table grade hydrogen peroxide was one of em. That stuff is sooo strong!! You really have to start by the drop and I don't mean in an 8oz glass of water! You need a larger container. The die off from my candida was so intense - I can't even compare anything else like it in my path to healing. Some days I couldn't make it go past my lips. I would put my little drop in my big glass of water and stand there and look at it; but I couldn't make myself do it! If you accidentally get it on your skin it will burn you so you have to handle very carefully. I ordered mine from some place in Arizona, but it's been so long I can't remember the place. Seems likethis stuff should be quite effective in killing off parasites - I haven't read up on Hulda Clark 's take on it. Good luck.
