Vomiting is one of the ten things that should be removed from the body by Ibn al-Qayyim al-Jauziyah in his book Zad al-Ma'ad. Thus, we should not stop vomiting if it felt like vomiting unless excessive vomiting frequency.
Vomiting is one of the methods used by the body to remove mucus from the body that interfere with the digestive and respiratory systems. This method is often used by experts gurah to the patient. Maintain health by doing more suited vomiting during hot weather, for example in the summer (in the 4 seasons) or in the dry season. Hot weather tends to draw the mucus making it easier to remove. When the weather is cold, the mucus in the body will experience freezing making it difficult to ride / expelled through vomiting. When mucus can not be expelled through vomiting, then the mucus excreted through feces.
