Is Auriculotherapy Responsible for Improvements on Anxiety Students' Prior and After Examinations?

To treat anxiety, conventional medicine relies on medicines such as benzodiazepines, antidepressants, barbiturates, and antihistamines. However, several authors have reported western medicine cannot resolve all anxiety diseases and the risk of side effects, resistance to pharmacological treatments affects approximately one in three patients with anxiety disorders.

Alternatively, auriculotherapy is a technique similar to reflexology. It is speculated the technique might work in anxiety because groups of pluripotent cells contain information from the whole organism creating regional organization centres representing different parts of the body, through the recruitment of more cortex cells dedicated to specific body areas. Thus reflex points in the ear can incite body responses by the stimulation of reticular formation and the sympathetic and parasympathetic nervous systems. The information that comes from the thermal, Algic and proprioceptive stimuli are transmitted from the auricular pavilion by the fibres of the nerves: trigeminal; Auricular magnum and minor occipital (sensitive branch of the cervical plexus) and the vagus nerve. The vagus nerve is responsible for the parasympathetic innervation of the lung, heart, stomach, and small intestine, as well as the pharynx and larynx muscles and it also sends information to important brain regions (e.g., locus coeruleus, orbitofrontal cortex, hippocampus and at amygdala) in the regulation of anxiety. In turn, the trigeminal nerve controls, mainly, the mastication muscles and the facial sensitivity while the cervical plexus nerve is responsible for neck muscles, diaphragm, and thorax.
