Purification could be explained in practical and general terms as a cleaning of something that is considered wrong, negative or dangerous in an organism, object, etc. Whenever we talk about purification, we are referring not only to cleaning like any other, but to a type of cleaning that is much deeper, designed and controlled for a specific purpose. Thus, the term can be applied when talking about the purification of water to transform it into drinking water (a cleaning that requires a lot of effort and without which the water could not be consumed), the purification of a computer system (in which case we would be talking about computer errors or viruses that can endanger the proper functioning of a device), etc.
The term purification is a very common term, as one might suppose, in the field of medicine and pharmacy. This is so because, as mentioned above, the idea of purification always implies that there is a malignant or dangerous presence that can threaten the proper functioning or well-being of the body. For this reason, purification in medicine can refer, for example, to the cleaning of the stomach that a person must receive in the face of excessive consumption of malignant substances, in the presence of cancer cells, in the face of a viral disease, in the face of infections that occur. they can give from very deep burns, etc. Both medical and pharmaceutical treatments will aim to deeply cleanse the body and avoid the complications that all these and other situations could represent for it.
There is a way of using the term purification that is very negative and that has been associated with different very cruel and dark historical phenomena. In the social sphere, purification refers to a racist and xenophobic concept or idea that some societies have shown at specific times with respect to social, ethnic or cultural groups with which they lived and that, according to the former, represented a danger to their security. Thus, the Nazi purification of Jews, Poles or Afro-Americans as well as the purification of Armenians caused by the Turks, the purification of aborigines carried out in America has always had a negative connotation since it represents the elimination and extermination of an ethnic group or socially violent and very cruel.
