Battle between plants as antioxidants with free radicals in human body

Free radicals are constructed by natural physiological activities in the human cells as well as in the environment. They may be produced as a result of diet, smoking, exercise, inflammation, exposure to sunlight, air pollutants, stress, alcohol and drugs. Imbalanced redox status may lead to cellular oxidative stress, which can damage the cells of the body, resulting in an incidence of various diseases. If the endogenous antioxidants do not stop the production of reactive metabolites, they will be needed to bring about a balance in redox status. Natural antioxidants, for example plants, play an important part in this context. This paper seeks to report the available evidence about oxidative stress and the application of plants as antioxidant agents to fight free radicals in the human body. For this purpose, to better understand oxidative stress, the principles of free radical production, the role of free radicals in diseases, antioxidant defense mechanisms, and the role of herbs and diet in oxidative stress are discussed. Keywords: Free radicals, Antioxidant, Plant, Human health, Oxidative stres

Hot And Cold: An Old Theory With Modern Applications

The use of traditional medicine as an important part of complementary/alternative medicine spread nowadays all around the world. Something that is due to the lack of effectiveness of modern medicine in treating some disease especially chronic disease. Since one of the most important theories beside traditional medicine is the concept of “temperaments” and this is very close to the concept of personalized medicine, which is taken into consideration nowadays. It is important to investigate what really temperament is and also reach a precise meaning and criteria for determining it. For reviewing all the researches that have been done on temperaments till today, the most popular database like PubMed, Scopus, Google scholar, science direct and etc. were searched for keywords Hot and cold, temperaments, hot and cold medicine, hot and cold nature, hot and cold parameters till September 2015. The results show that there are some physiological and metabolic criteria, genes and networks and metabolite that contribute in determining the temperaments not only in body but also in disease, foods and drugs. Despite the presence of all these detailed data the lack of a comprehensive practical criteria for temperament is still obvious, so we try to gather all data to reach that in its best way.</p
