I can see that.
However, crystals is as natural as other minerals, which taken orally, can heal a person. These minerals are called medicines. Crystal Therapy is also seen as an alternative healing technique, similar to acupuncture and message therapy. Laying on of hands for healing is also similar. It is about using natural resources to aid in healing. That is what this sub-forum (Natural health) is about.
Crystal structures of certain elements are used for treating cancer patience with radiation therapy.
What I am say is that certain uses of God's natural elements, such as crystals, often contribute to a persons healing. Unfortunately, many practitioners, like our own early and historical experiments in medicine was quite often a hit or miss experience. So too are the many alternative therapeutic techniques used today. Even medicines have to go on trial runs before approval. Most crystal therapists know what certain things work for certain situations, but cannot yet explain the exact reasons. There is still much the medical practitioner, and research medical scientists don't know. They are still classed as miracles. Even Jesus used saliva and an earth to make mud as a means for aiding the healing process. Can medical science explain that? No, it can't, not yet anyway.
Much has to do with faith, and faith is important in the medical field too. It is a strange phenomenon, and we humans are capable of using faith in God for healing. Or even the so-called lack of faith can stop healing (which is faith that it won't work).
If a person believes that a medicine (even a placebo) will work, it will.
There are doctors, and patients, that believe it was the doctor that healed them. No, that is not true! All the doctor can do is provide assistance to the body. It is the body which goes through the healing process, not the doctor. The body is under control to the person's mind, and the mind is also connected to the soul. Whatever collaboration is happening between mind and soul governs the healing processes. But can medical science prove that one. No, it cannot as of yet, for the medical authorities still won't rely on God.
Used in the correct way, both scientifically and spiritually (via guidance by the Holy Spirit), and in collaboration between patient and God, crystals therapy, and other alternative therapies, can be used as a tool for healing.
