Which modality is classified as a mind-body therapy in complementary medicine?

A. Chelation therapy: This modality involves the administration of ethylenediaminetetraacetic acid or other agents to remove heavy metals from the bloodstream. It is a biological-based chemical intervention rather than a mind-body practice focusing on the interaction between mental and physical health. It is primarily used for heavy metal toxicity or experimental cardiovascular treatment. B. Magnetic therapy: This practice utilizes static magnetic fields from permanent magnets with the intent of promoting healing or relieving pain in specific body parts. It is categorized as an energy-based therapy or a manipulative and body-based method within complementary medicine. It does not rely on the conscious mental state of the patient. C. Meditation: This mind-body therapy involves focusing attention or clearing the mind to promote relaxation and physiological homeostasis. It utilizes the mental faculties to influence physical health by reducing sympathetic nervous system activity and lowering stress-related cortisol levels. It exemplifies the integration of cognitive processes with somatic well-being and health. D. Chiropractic manipulation: This technique involves the manual adjustment of the spinal column and other joints to improve structural alignment and nervous system function. It is classified as a manipulative and body-based modality rather than a mind-body therapy. Its primary mechanism is physical and mechanical rather than being driven by mental focus.
