I am sorry to hear about what you have been through but I very much doubt that restoring something which has been removed is possible. The human body can heal but I still think that what you want is nigh on impossible and only wishful thinking.
However, to optimize healing and remove the restrictions on healing I think it might be worth you looking at iridology and in particular the nerve rings which are created by repressed emotions and drives as these are what prevent regeneration of the nervous system and hence affect healing. I do know that things such as Depression can be healed by removing nerve rings and stimulating healing but I have some doubts about whether that could be extended to regenerating a womb that has been removed. Problems with carrying a child full term or getting pregnant is indeed possible but I do not want to falsely raise your hopes under your circumstances.
Note that black markings represents tissue destruction/death whereas grey show poor immune system regulation and slow/reduced healing. The nerve rings which show as shadows in the iris are synonymous with the Traditional Chinese Medicine concept of Qi/Chi which has been known about for thousands of years. The nerve rings slowly get tighter as a person ages and they reduce nerve impulses to all areas of the body. They are caused by repressed drives and emotions such as not being able to feel sad or cry or being afraid of expressing anger. These all cause the associated nerve ring to become tighter and more restrictive over time which ultimately increase ageing, ie healing/repair of damage in the body. There are various Chinese herbs which are known to reduce these rings and many have been classified as working on different body systems. German chamomile essential oil can also do this but tends to work mainly on the liver/lungs but working on the liver means to it does affect all areas to some degree. Herbalife's Herbal Aloe drink can do this however earlier versions worked much better than more recent formulations. It does contain German Chamomile eo and Aloe vera and did in an earlier formulation contain alfalfa extract. Buying a pure form of German Chamomile eo and Aloe vera would be much cheaper.
