Alternative Medicine is not magic, it is a science based on hundreds of years of experience and experimentation. It helps heal the body naturally, without any use of chemicals that bring about strong and instant reactions in the body. For this very reason, it takes time to bring about healing.
No disease occurs suddenly. It manifests slowly and if the signs are recognized at an early stage, preventive measures can be taken. However, not everyone knows how to read the signs and they finally realize only when they really feel unbearable pain or sickness. At this stage, they might come to you for healing and look for immediate results after the first session itself.
As therapists, it is our responsibility to first explain to them how healing takes place. In any kind of alternative medicine, energy channels are cleared up and healing is stimulated. Toxins come out in natural forms like sweat, mucous, urine, etc. Since the elimination process is natural, it will take time and will depend on the regularity of the treatments.
You can even include this information as a clause in the consent form the clients will fill and sign. They are welcome to take a trial session first, and if they like it, advice them to book the next session (it is up to you to judge how often they need treatment). They are likely to ask how long it will take to heal. Inform them that recovery time depends on the nature and intensity of the problem, the reaction of the client's body to the treatment, frequency of treatment, etc. It is different for everyone and can be gauged with regular treatment. You can take notes and record the progress of each client for a better study.
However, remember that alternative medicine is not a replacement for medical treatment. Make sure clients with serious problems have a doctor's written approval.
After each session, ask for client feedback on how they feel. Call them the next day to see how they are progressing. But emphasize on regularity!! Otherwise all efforts on both parts will be void.
Work hard and keep healing!!
