Humors
Humorism, the humoral theory, or humoralism, was a system of medicine detailing a supposed makeup and workings of the human body, adopted by Ancient Greek medicine, Ancient Greek and Medicine in ancient Rome, Roman physicians and Greek philosophy, philosophers. Humorism began to fall out of favor in the 1850s with the advent of germ theory, which was able to show that many diseases previously thought to be humoral were in fact caused by microbes. Origin The concept of "humors" (chemical systems regulating human behaviour) became more prominent from the writing of medical theorist Alcmaeon of Croton (c. 540–500 BC). His list of humors was longer and included fundamental elements described by Empedocles, such as water, air, earth, fire, etc.. The concept of "humors" may have origins in Ancient Egyptian medicine, or Mesopotamia, though it was not systemized until ancient Greek thinkers. The word ''humor'' is a translation of Greek χυμός, ''chymos'' (literally juice or sap, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek Medicine
Ancient Greek medicine was a compilation of theories and practices that were constantly expanding through new ideologies and trials. Many components were considered in ancient Greek medicine, intertwining the spiritual with the physical. Specifically, the ancient Greeks believed health was affected by the humors, geographic location, social class, diet, trauma, beliefs, and mindset. Early on the ancient Greeks believed that illnesses were "divine punishments" and that healing was a "gift from the Gods". As trials continued wherein theories were tested against symptoms and results, the pure spiritual beliefs regarding "punishments" and "gifts" were replaced with a foundation based in the physical, i.e., cause and effect. Humorism (or the four humors) refers to blood, phlegm, yellow bile and black bile. Each of the four humors were linked to an organ, temper, season and element. It was also theorized that sex played a role in medicine because some diseases and treatments were diffe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
On The Nature Of Man
''On the Nature of Man'' is a work in the Hippocratic Corpus. ''On the Nature of Man'' is attributed to Polybus, the son in law and disciple of Hippocrates, through a testimony from Aristotle's ''History of Animals''.However, as with the many other works of the Hippocratic Corpus, the authorship is regarded as dubious in origin. ''On the Nature of Man'' attempts to explain the human body in its anatomy and composition. The content is based on observation and defended by logical explanations of the causes of each disease in order to readily meet outside criticism. It places emphasis on disease not being of divine origin, but rather an imbalance of the four humors (collection of blood, phlegm, black bile, and yellow bile) in the body. This was the first introduction of the theory of four humors which was used to explain and diagnose any disease or aliment as an imbalance of these four humors in the body excluding health issues that arose from an outside source.

Dyscrasia
In medicine, both ancient and modern, a dyscrasia is any of various disorders. The word has ancient Greek roots meaning "bad mixture". The concept of dyscrasia was developed by the Greek physician Galen (129–216 AD), who elaborated a model of health and disease as a structure of elements, qualities, humors, organs, and temperaments (based on earlier humorism). Health was understood in this perspective to be a condition of harmony or balance among these basic components, called eucrasia. Disease was interpreted as the disproportion of bodily fluids or four humours: phlegm, blood, yellow bile, and black bile. The imbalance was called dyscrasia. In modern medicine, the term is still occasionally used in medical context for an unspecified disorder of the blood, such as a plasma cell dyscrasia. Ancient use To the Greeks, it meant an imbalance of the four humors: blood, black bile, yellow bile, and water (phlegm). These humors were believed to exist in the body, and any change in th ...

Medicine In Ancient Rome
Medicine in ancient Rome was highly influenced by ancient Greek medicine, but also developed new practices through knowledge of the Hippocratic Corpus combined with use of the treatment of diet, regimen, along with surgical procedures. This was most notably seen through the works of two of the prominent Greek physicians, Dioscorides and Galen, who practiced medicine and recorded their discoveries. This is contrary to two other physicians like Soranus of Ephesus and Asclepiades of Bithynia, who practiced medicine both in outside territories and in ancient Roman territory, subsequently. Dioscorides was a Roman army physician, Soranus was a representative for the Methodic school of medicine, Galen performed public demonstrations, and Asclepiades was a leading Roman physician. These four physicians all had knowledge of medicine, ailments, and treatments that were healing, long lasting and influential to human history. Ancient Roman medicine was divided into specializations such as oph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galen
Aelius Galenus or Claudius Galenus ( el, Κλαύδιος Γαληνός; September 129 – c. AD 216), often Anglicized as Galen () or Galen of Pergamon, was a Greek physician, surgeon and philosopher in the Roman Empire. Considered to be one of the most accomplished of all medical researchers of antiquity, Galen influenced the development of various scientific disciplines, including anatomy, physiology, pathology, pharmacology, and neurology, as well as philosophy and logic. The son of Aelius Nicon, a wealthy Greek architect with scholarly interests, Galen received a comprehensive education that prepared him for a successful career as a physician and philosopher. Born in the ancient city of Pergamon (present-day Bergama, Turkey), Galen traveled extensively, exposing himself to a wide variety of medical theories and discoveries before settling in Rome, where he served prominent members of Roman society and eventually was given the position of personal physician to several emp ...

Alcmaeon Of Croton
Alcmaeon of Croton (; el, Ἀλκμαίων ὁ Κροτωνιάτης, ''Alkmaiōn'', ''gen''.: Ἀλκμαίωνος; fl. 5th century BC) was an early Greek medical writer and philosopher-scientist. He has been described as one of the most eminent natural philosophers and medical theorists of antiquity and he has also been referred to as "a thinker of considerable originality and one of the greatest philosophers, naturalists, and neuroscientists of all time." His work in biology has been described as remarkable, and his originality made him likely a pioneer. Because of difficulties dating Alcmaeon's birth, his importance has been neglected. Biography Alcmaeon was born in Croton and was the son of Peirithous. Alcmaeon is said by some to have been a pupil of Pythagoras, and he is believed to have been born c. 510 BC. Although he wrote primarily about medical topics, there is some suggestion that he was a philosopher of science, not a physician. He also practiced astrology and ...

Bile
Bile (from Latin ''bilis''), or gall, is a dark-green-to-yellowish-brown fluid produced by the liver of most vertebrates that aids the digestion of lipids in the small intestine. In humans, bile is produced continuously by the liver (liver bile) and stored and concentrated in the gallbladder. After eating, this stored bile is discharged into the duodenum. The composition of hepatic bile is (97–98)% water, 0.7% bile salts, 0.2% bilirubin, 0.51% fats (cholesterol, fatty acids, and lecithin), and 200 meq/L inorganic salts. The two main pigments of bile are bilirubin, which is yellow, and its oxidised form biliverdin, which is green. When mixed, they are responsible for the brown color of feces. About 400 to 800 millilitres of bile is produced per day in adult human beings. Function Bile or gall acts to some extent as a surfactant, helping to emulsify the lipids in food. Bile salt anions are hydrophilic on one side and hydrophobic on the other side; consequently, they tend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ayurveda
Ayurveda () is an alternative medicine system with historical roots in the Indian subcontinent. The theory and practice of Ayurveda is pseudoscientific. Ayurveda is heavily practiced in India and Nepal, where around 80% of the population report using it. Ayurveda therapies have varied and evolved over more than two millennia. Therapies include herbal medicines, special diets, meditation, yoga, massage, laxatives, enemas, and medical oils. Ayurvedic preparations are typically based on complex herbal compounds, minerals, and metal substances (perhaps under the influence of early Indian alchemy or ''rasashastra''). Ancient Ayurveda texts also taught surgical techniques, including rhinoplasty, kidney stone extractions, sutures, and the extraction of foreign objects. The main classical Ayurveda texts begin with accounts of the transmission of medical knowledge from the gods to sages, and then to human physicians. Printed editions of the '' Sushruta Samhita'' (''Sushruta's Compen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Four Temperaments
The four temperament theory is a proto-psychological theory which suggests that there are four fundamental personality types: sanguine, choleric, melancholic, and phlegmatic. Most formulations include the possibility of mixtures among the types where an individual's personality types overlap and they share two or more temperaments. Greek physician Hippocrates (c. 460 – c. 370 BC) described the four temperaments as part of the ancient medical concept of humourism, that four bodily fluids affect human personality traits and behaviours. Modern medical science does not define a fixed relationship between internal secretions and personality, although some psychological personality type systems use categories similar to the Greek temperaments. History Temperament theory has its roots in the ancient theory of humourism. It may have originated in Mesopotamia, but it was Greek physician Hippocrates (460–370 BC) (and later Galen) who developed it into a medical theory. He believed th ...

Complexion
Complexion in humans is the natural color, texture, and appearance of the skin, especially on the face. History The word "complexion" is derived from the Late Latin ''complexi'', which initially referred in general terms to a combination of things, and later in physiological terms, to the balance of humors. The four humours were four fluids that were thought to permeate the body and influence its health. The concept was developed by ancient Greek thinkers around 400 BC and developed further by Galen.Matthew Simon, ''Emergent Computation: Emphasizing Bioinformatics'' (Springer, 2005), 145. People were thought to be either of the four temperaments: choleric, melancholic, phlegmatic, or sanguine. During the Middle Ages in Europe, the Latin term ''complexio'' served as the translated form of the Greek word ''crasis'', meaning temperament. The term “temperament” referred to the balance of the qualities of hot, wet, cold, and dry; each human body carried a different mixture of th ...

Erythrocyte Sedimentation Rate
The erythrocyte sedimentation rate (ESR or sed rate) is the rate at which red blood cells in anticoagulated whole blood descend in a standardized tube over a period of one hour. It is a common hematology test, and is a non-specific measure of inflammation. To perform the test, anticoagulated blood is traditionally placed in an upright tube, known as a Westergren tube, and the distance which the red blood cells fall is measured and reported in millimetre at the end of one hour. Since the introduction of automated analyzers into the clinical laboratory, the ESR test has been automatically performed. The ESR is governed by the balance between pro-sedimentation factors, mainly fibrinogen, and those factors resisting sedimentation, namely the negative charge of the erythrocytes (zeta potential). When an inflammatory process is present, the high proportion of fibrinogen in the blood causes red blood cells to stick to each other. The red cells form stacks called ''rouleaux'' which ...
