Live Blood cell demonstrations is something often used by homeopaths and nutritionists in order to develop a plan for a patient. During the consultation a drop of blood from the patient is placed under a microscope and then viewed on a television screen by both the patient and practitioner together. This process allows the practitioner to determine various things such as multiple vitamin and mineral deficiencies, toxicity, and tendencies toward allergic reaction, excess fat circulation, liver weakness and arteriosclerosis.
