Sorry for the belated response - I was mostly out of pocket over the weekend and just returned for a brief spell at the computer.
I have not heard of oleander being taken specifically for HPV, though I imagine it would be a good item to include due to its potent anti-viral properties. It definitely would be a good item, imo, for cervical cellular changes. Other items I would take for HPV would include copious colloidal silver, olive leaf extract and oil of oregano.
