Conventional medical system analyses disease in terms of molecular changes in a patient. It uses drugs aimed at counteracting these changes to alleviate the physical symptoms. These drugs are either concentrates of certain extracts or synthetic formulations. They have their own side effects too. Side effects may vary from person to person, may be due to different constitutions. It may also vary from time to time in the same person depending on physical, mental or emotional conditions of the person at the time when the medicine is administered.
Reiki boosts the internal energy of the patient to alleviate the physical symptoms. Since nothing is administered from outside so there cannot be any side effects. Moreover it is said that Reiki has its own intelligence. It reaches wherever it is needed most and replenishes the deficiency.
