Editing Humorism (section)

===Modern use===
Humoral theory was the grand unified theory of medicine, before the invention of modern medicine, for more than 2,000 years. The theory was one of the fundamental tenets of the teachings of the Greek physician-philosopher Hippocrates (460–370&nbsp;BC), who is regarded as the first practitioner of medicine, appropriately referred to as the "Father of Modern Medicine".<ref name=":5">{{cite journal |last1=Bhikha |first1=Rashid |last2=Glynn |first2=John |date=2017 |title=The Theory of Humours Revisited |url=https://www.academia.edu/44065524 |journal=International Journal of Development Research |volume=7 |issue=9 |pages=15029–15034}}</ref>

With the advent of the [[Doctrine of Specific Etiology]], the humoral theory's demise hastened even further. This demonstrates that there is only one precise cause and one specific issue for each and every sickness or disorder that has been diagnosed.<ref name=":5" /> Additionally, the identification of messenger molecules like hormones, growth factors, and neurotransmitters suggests that the humoral theory has not yet been made fully moribund. Humoral theory is still present in modern medical terminology, which refers to humoral immunity when discussing elements of immunity that circulate in the bloodstream, such as hormones and antibodies.<ref name=":5" />

Modern medicine refers to [[humoral immunity]] or humoral regulation when describing substances such as [[hormone]]s and [[antibody|antibodies]], but this is not a remnant of the humor theory. It is merely a literal use of ''humoral'', i.e. pertaining to bodily fluids (such as blood and lymph).

The concept of humorism was not definitively disproven until 1858.<ref name=NYT/><ref name=Webster/> There were no studies performed to prove or disprove the impact of dysfunction in known bodily organs producing named fluids (humors) on [[temperament]] traits simply because the list of temperament traits was not defined up until the end of the 20th century.
