He is one of the most influential Greek scholar in Persian medicine, who has been repeatedly cited by Iranian scholars. The purpose of this article is to describe the exact position of Galen in Avicenna’s The Canon of Medicine, the most important work of Persian medicine. In The Canon of Medicine, Galen is cited about 300 times, and Avicenna always admired and praised Galen repeatedly. Galen’s ideas were important to Avicenna, but there are also many elements of Galen’s views that Avicenna challenged or criticized. For example, Avicenna diverged from Galen’s philosophical view in medicine and rejected some of Galen’s pharmaceutical opinions and Galen’s views on the physiology of pain, the physiology of pulse, the same nature of the tendons and nerves and separation of the mind and body. Although the views of Greek scholars, especially Galen, in The Canon of Medicine have been quoted abundantly, Avicenna revised the knowledge of the ancient scholars through critical thinking and relying on observation and testing, systematized the science of medicine and introduced many ideas and innovations. As such, Europeans considered Avicenna as the most prominent physician of the Islamic Golden Age.展开更多

However, the best quantity of daily water consumption for a healthy individual is not virtually stated in the literature. Despite the dearth of evidence-based recommendations, it is commonly thought that ingesting eight glasses of water a day is good for a healthy person. Avicenna had a unique viewpoint. He believed that daily water intake depended on numerous elements together with age, intercourse, body temperament, season, occupation and various internal and external elements. He also cited a few essential and usefu measures regarding proper water consumption, which have additionally been emphasized in Islamic hadiths.展开更多

Avicenna believed that skin is the most balanced organ in the body. His interpretation is that according to quality perspective, hotness-coldness and wetness-dryness, skin is more moderate in comparison with other organs. Traditional Persian sages （Hakim） emphasized on the role of these quadruple qualities＇ balance on health. They believed that every organ, based on its function.展开更多

In this review, we are seeking the views of Avicenna, the most distinguished Persian medical scholar about digestion and indigestion. Avicenna’s view was based on the humoral theory. Avicenna has focused scrutiny on the process of digestion. He divided this process into four phases including gastric, hepatic, intravascular and intra-organ digestion. A defect in any of these phases can lead to disturbance in other stages. Avicenna approached the problem of indigestion through factors of diet, lifestyle and inherent structural characteristics of digestive organs. Modern medicine confirms Avicenna's opinion about the start of digestion from the mouth, the role of the stomach in digestion and the role of the liver in the metabolism of foods. Overeating or eating certain foods, snacking between meals, eating variety of different foods together, intense physical activity, sexual activity after a meal, stress and sleep insufficiency are among factors that may be linked to indigestion in modern medicine viewpoints and also have been mentioned in Avicenna's teachings. It seems rational to consider the medical approaches recommended by Avicenna for future studies in the field of digestive disorders.展开更多

The aim of the present study was to clarify the perspective of Avicenna on periconceptional care. Avicenna(980–1037 A.D.) was one of the outstanding Persian physicians, who made great contributions to the field of medical sciences, in particular, obstetrics. In advance, Avicenna's book, Canon of Medicine, was considered to find his perspectives on periconceptional care. Then, his ideas and theories were compared to the current findings by searching the keywords in main indexing systems including PubMed/MEDLINE,Scopus and Institute for Scientific Information Web of Science as well as the search engine of Google Scholar. Current investigations show that gamete quality, pregnancy outcome, and offspring health at birth and long term depend on both parents' lifestyle in pre-and periconceptional period, as well as the intrauterine environment. Avicenna believed that seminal fluid, sperm, ovum, and developing conditions in utero were influenced by the stages of food digestion and the function of some organs.On the other hand, food digestion and function of the organs also depend on each parent's lifestyle and environmental factors. He mentioned 6 principles of healthy lifestyle: exercise, nutrition, sleep and awareness, excretion of body wastes and retention of necessary materials, psychic features, as well as air and climate. Thus, a multicomponent healthy lifestyle should be considered by parents of child-bearing age in an appropriate period before and in early pregnancy as well as elimination of any disorders in parents, to give birth to more healthy offspring.展开更多

The evolution of this branch of medicine is indebted to investigations of many scientists, including Greek, Roman and Persian scholars. The Persian physician Avicenna(980-1037 AD) is one such scientist who investigated different aspects of orthopedics. It is possible to analyze Avicenna's knowledge of orthopedics and his contributions to this branch of medicine by an examination of his epic encyclopedia of medicine, Al-Qanun fi al-Tibb(The Canon of Medicine).展开更多
