Natural health: Raynaud’s disease and mosquito bites

My daughter, aged 12, has begun to suffer from extreme coldness all over her body, but especially in her hands and feet. 

Her hands turn white and then red at times. She complains bitterly (sometimes cries) of the cold despite the fact that she may be wearing several layers of clothing. This only started a number of months ago. What can we do to help her?

This sounds very much like Raynaud’s disease where the affected areas turn white and numb, followed by a compensatory increase in blood flow which causes the redness before the area returns to its usual skin colour.
