Hello, I am Shafi Ullah Khan, I have a sister and she is 15 years old. She is a heart patient from childhood. She has a minor problem of Heart Valves, they are not completely closed. Due to that heart problem, Her Lips and Nails colour is Dark Blue. We consult to many doctors but there is no good sign of result. We are very worried about her. She has a low resistance against any illness. She got tired very soon. Whenever she walk upstairs or outside home, her whole face turned into Blue shade. She likes Tea very much. I tried to stop her many times but she never stops. Plz give me some good suggestion about her health and diet. Plz also tell me prescription about her.
