There are no known contraindications for Reiki treatment.
Nothing is ingested during a Reiki treatment and no oils or creams are applied to the skin.
Reiki touch is light, and non-manipulative. And touch is not even necessary – a full and effective treatment can be given without physical contact. So in cases where even light touch would be painful or inadvisable for any reason, Reiki treatment can still be safely administered.
You can never overdose on Reiki as it simple stops flowing once you have drawn all that you need at any given time.
You can receive Reiki treatments on their own, or along with any other form of care, knowing that they will only enhance and never hinder your journey towards a healthier, more balanced state.
