I am a director of Zhongguancun Science Park, Beijing., China. I have accumulated some knowledge in this field. Now I tell the patients how to make "Calcium shield" out of sympathy. It may bring you great surprise. The details: make bone powder cake use the animal bones powder. Because calcium is the main component of bone powder cake, we can it calcium cake. In the science field we call it calcium shield. First press the bone powder to 10cm' thicknesses with high intensity. And then put it under the bed, at the same time put the same one beyond your bed as long as the patients can sit down without touching the calcium shield. The length and width is the same to the bed. Keep it for 8-10 months it can bring an obvious healing effects as long as the patients are not in terminal period. If you want to know more details:please contact me at :jennydailyhappy@yahoo.com.cn
