Nausea is the subjective sensation of needing to vomit. It may or may not be followed by vomitting. Vomitting is a defense reflex that lets the organism to get rid of toxins by oral expulsions of gastrointestinal contents by contractions of gut and thoracic and abdomenal muscles. The vomitting reflex is initiated by the vomitting center in the brain which responds to various stimulations including those of the chemo and mechanoreceptors of the gut. Afferent nerves to the vomitting center in the brain rise from internal splanchnic and vagal nerves, vestibulo labyrinthrine receptors in the inner ears, and also from the cerebral cortex, and the chemoreceptor trigger zone ( CTZ ) which detect noxious chemicals from the blood. Thus CTZ is exposed to both the emetic stimuli from endogenous origin such as changes in hormonal levels or endotoxins coming from the liver or gut and to stimuli of external origin such as exotoxins being directly absorbed by the respiratory and gastrointestinal mucosa. The efferent branches of cranial nerves V, VII, IX, X and the spinal nerves coordinate muscular contractions of the gut ( reverse peristalsis ), the diaphragms, and thoracic and abdomenal muscles.
In short there are numerous different types of Nauseating Stimuli acting on the vomitting center mainly from 1) neural input from the gut and 2) hormones and chemicals in blood sensored by CTZ with additional inputs from the inner ear and finally modulated by the cortex. In simple terms nausea and vomitting is mainly caused by 1) any harmful stimulations of the gut, 2) any harmful chemicals and altered hormone levels in the blood, and is subject to the psychological modulations by the cortex.
Therefore, Nausea and Vomitting has multiple pathogenetic mechanisms.Recurrent chronic nausea/vomitting can be often idiopathic after medical work ups and refractory to medications, but natural herbal remedies for nausea and vomitting can steadily treat the roots by tonifying the weak bioenergy and removing the obstruction of it in the neurohormonal circuitry of gastrointestinal system.
In eastern herbal medicine, nausea/ vomitting represents abnormal upwards movements of Qi. Most often it is the stomach qi, but may also be heart qi, liver qi, or qi of the penetrating vessel ( the bioenergetic system enabling the pregnancy ). Abnormal movements of qi may arise because 1) there is a low level of bioenergy which cannot power the transformations needed for normal peristalsis, or 2) there are obstructions to the normal flows of bioenergies caused by inflammations and edemas of the gut, or 3) varying combinations of both 1) deficiency and 2) excess. The diagnosis of nausea can be arrived at by careful analysis of all the symptoms and physical signs such as tongue appearance which may be the most visible and objective indicators of the state of various bioenergies.
