Yes Urine therapy can help tremendously with anemia, especially if it is severe. Getting alot of sunlight when it's warm out and staying hydrated will help with that too. lots of Flourecent light is not good. Has she started urine therapy? When is the flight? I don't know if travel like that would really hurt anything but it would be good to try a short couple day urine fast also. While eating well and staying hydrated Urine should be mostly clear always, except in the mornings. To get desired results she must drink all that she passes during the day, it'll be clear water with Urea, not bad at all. the more urea consumed the faster the anemia and other dis eases will subside. It will not happen overnight but if it is practiced like one would take any other tea or medication daily the effectiveness of this method will start to shine through very quickly. And especially for anemia, it would be good to do urine massages into the skin with a light hand daily for at least one good hour, keep layering as it drys, and she can definitely heat it in a pan on the stove so it's warm not boiling. (I have not tried boiling, some say it is good some say it isn't - try everything once, I will to) 2 hour rubbings wouldn't even hurt for skin issues. In my opinion it's 50/50% with drinking urine & urine massages on the skin & for the true remarkable effects to begin. Good luck ~ if you have any questions this forum is a great place to ask, little quiet though - and I'd recommend reading John Armstrong's ~ The Water of Life pdf -good book
