A medieval anaemia remedy that may date back almost to the iron age involves putting nails in an apple. You leave them there to corrode for a couple of days. They are then taken out and the apple eaten by the patient. The citric acid in the apple combines with the iron in the nails to make ferric citrate, an efficient way of delivering iron to the anemic person. You need a good size apple and ten four inch nails acording to the Romanian traditional healing pundits. be careful to avoid steel nails or galvanised ones as these will not corrode properly. Anaemia may have made you weak but if you are prepared to follow this cure you are certainly not faint hearted.
