In ''vamana'', ''kapha utklesha''(excited) is expected which is evident by excess salivation, nausea etc. These factors plays an important role in induction of vomiting. The vagal and enteric nervous system inputs transmit information regarding the state of the gastrointestinal system. Irritation of the GI mucosa by any drug or distension activates the 5-HT3 receptors of these inputs. Thus if ''kapha'' is not aggravated then the key mechanism of distension of stomach, excess salivary secretions and nausea fails to initiate vomiting thus drug passes to the intestine and causes purgation. On contrary if ''kapha'' is highly aggravated then drug for purgation may lead to vomiting due to above said mechanism. This is the probable reason for specific diet before cleansing processes.
