Gas molecules for use in a procedure for treatment by electrostimulation of any of: (a) a site affected by a pathology in a subject, characterized in that the method comprises ionizing and transmitting the gaseous molecules by means of an ion transmission device gaseous which includes a gaseous ion generator and then providing said site with a net electric charge for a period of time subjecting the subject to a flow of the ionized gas molecules, so that an electric current is provided between said site and said tissue outside said site, in which the current through a return electrode connected to the treated subject is measured to allow control of the current sent through the treated subject as a consequence of the administration of the ionized gas molecules, or ( b) a subject suffering from asthma or another disease that is characterized by a pathology that involves freedom ation of histamine by mast cells or basophilic granulocytes, said process comprising ionizing and transmitting the gaseous molecules by means of a gaseous ion transmission device that includes a gaseous ion generator and then subjecting the subject to a flow of the ionized gas molecules during a period of time, said ionized gas molecules having a net positive or negative charge, in which the current through a return electrode connected to the treated subject is measured to allow control of the current sent through the treated subject as consequence of the administration of the ionized gas molecules.Moléculas de gas para su uso en un procedimiento para tratamiento mediante electroestimulación de cualquiera de: (a) un sitio afectado por una patología en un sujeto, caracterizado porque el procedimiento comprende ionizar y transmitir las moléculas gaseosas por medio de un dispositivo de transmisión de iones gaseosos que incluye un generador de iones gaseosos y a continuación proporcionar a dicho sitio una carga eléctrica neta durante un periodo de tiempo sometiendo al sujeto a un flujo de las molécu
