I have a holistic dentist who said taking PABA will keep you from burning. We tried it... it worked! I totally forgot until now. All last summer we took it and were fine. I do think seed oils changed our bodies and now we burn. I often think about how people in the past didn't all die from skin cancer... why not? they worked and lived outside. Something changed. Just like autism... they didn't all have autism, cancer, or the myriad of other diseases we get. Why? What changed? I like to find the root of the problem rather than the "cure"
