Thanks so much for the magnesium oil idea. I have suffered with Raynaud's for 20 years. One year I was free from it when taking Ginko. It quit working. I have been using the oil for 3 weeks now, and it took 2 weeks to notice a difference. I put it on twice a day, in the morning and before I got to bed. I rub it on the inside of my arm, from my wrist to my elbow. I am not completely symptom free, but I can go outside in the cold now without my hands turning white. It used to be that I couldn't get to the car without having to go back and put my fingers in hot water. Today in the snow I went to the grocery store and back, and it has been like that. I don't wear gloves because they never work. So you can imagine. I couldn't even sit in my computer room due to how cold it is, and I am now. Thank you so much. I also take magnesium tablets at night, but have been doing so for a year or more, but they did nothing for this condition.
