Thanks for writing in.
and proanthocyanidine granules are vasodilators and increase the blood circulation in the placenta and therefore the amount of oxygen
and nutrients reaching the baby. Since you have swelling in feet and hands, there is water retention. This can cause placental insufficiency
which may be harmful for the baby.
By giving l- arginine and proanthocyanidine granules any problems relating to restricted blood supply to the placenta can be controlled.
Hope this helps
