History Of Leprosy
The history of leprosy was traced to its origins by an international team of 22 geneticists using comparative genomics of the worldwide distribution of ''Mycobacterium leprae''. Monot ''et al.'' (2005) determined that leprosy originated in East Africa or the Near East and traveled with humans along their migration routes, including those of trade in goods and slaves. The four strains of ''M. leprae'' are based in specific geographic regions where each predominantly occurs: : Strain 1 – East Africa, Asia, and the Pacific region : Strain 2 – Ethiopia, Malawi, Nepal/North India, and New Caledonia : Strain 3 – Europe, North Africa, and the Americas; and : Strain 4 – West Africa and the Caribbean. They created a map of the dissemination of leprosy in the world. This confirmed the spread of the disease along the migration, colonisation, and slave trade routes taken from East Africa to India, West Africa to the New World, and from Africa into Europe ...

Gerhard Armauer Hansen
Gerhard Henrik Armauer Hansen () (29 July 1841 – 12 February 1912) was a Norwegian physician, remembered for his identification of the bacterium ''Mycobacterium leprae'' in 1873 as the causative agent of leprosy. His distinguished work was recognized at the International Leprosy Congress held at Bergen in 1909. Life Hansen was born in Bergen, Norway, and attended the Bergen Cathedral School. He worked at Rikshospitalet in Christiania (now Oslo) and as a doctor in Lofoten. In 1868 Hansen returned to Bergen to study leprosy while working at Lungegård Hospital (''Lungegårdshospitalet'') with Daniel Cornelius Danielssen, a noted expert. Leprosy was regarded as largely hereditary or otherwise miasmic in origin. Hansen concluded on the basis of epidemiological studies that leprosy was a specific disease with a specific cause. In 1870–71 Hansen travelled to Bonn and Vienna to gain the training necessary for him to prove his hypothesis. In 1873, he announced the discovery ...

Hebrew People
The terms ''Hebrews'' (Hebrew: / , Modern: ' / ', Tiberian: ' / '; ISO 259-3: ' / ') and ''Hebrew people'' are mostly considered synonymous with the Semitic-speaking Israelites, especially in the pre-monarchic period when they were still nomadic. However, in some instances it may also be used in a wider sense, referring to the Phoenicians, or to other ancient groups, such as the group known as Shasu of ''Yhw'' on the eve of the Bronze Age collapse, which appears 34 times within 32 verses of the Hebrew Bible. It is sometimes regarded as an ethnonym and sometimes not. By the time of the Roman Empire, Greek ''Hebraios'' could refer to the Jews in general, as ''Strong's Hebrew Dictionary'' puts it, "any of the Jewish Nation", and at other times more specifically to the Jews living in Judea. In early Christianity, the Greek term refers to Jewish Christians as opposed to the gentile Christians and Judaizers (Acts 6:1 among others). is the province where the Temple was located. ...

Herbal Medicine
Herbal medicine (also herbalism) is the study of pharmacognosy and the use of medicinal plants, which are a basis of traditional medicine. With worldwide research into pharmacology, some herbal medicines have been translated into modern remedies, such as the anti-malarial group of drugs called artemisinin isolated from ''Artemisia annua'', a herb that was known in Chinese medicine to treat fever. There is limited scientific evidence for the safety and efficacy of plants used in 21st century herbalism, which generally does not provide standards for purity or dosage. The scope of herbal medicine commonly includes fungal and bee products, as well as minerals, shells and certain animal parts. Herbal medicine is also called phytomedicine or phytotherapy. Paraherbalism describes alternative and pseudoscientific practices of using unrefined plant or animal extracts as unproven medicines or health-promoting agents. Paraherbalism relies on the belief that preserving various subst ...

Gautama Buddha
Siddhartha Gautama, most commonly referred to as the Buddha, was a wandering ascetic and religious teacher who lived in South Asia during the 6th or 5th century BCE and founded Buddhism. According to Buddhist tradition, he was born in Lumbini, in what is now Nepal, to royal parents of the Shakya clan, but renounced his home life to live as a wandering ascetic ( sa, śramaṇa). After leading a life of begging, asceticism, and meditation, he attained enlightenment at Bodh Gaya in what is now India. The Buddha thereafter wandered through the lower Indo-Gangetic Plain, teaching and building a monastic order. He taught a Middle Way between sensual indulgence and severe asceticism, leading to Nirvana, that is, freedom from ignorance, craving, rebirth, and suffering. His teachings are summarized in the Noble Eightfold Path, a training of the mind that includes meditation and instruction in Buddhist ethics such as right effort, mindfulness, and '' jhana''. He di ...

Sushruta Samhita
The ''Sushruta Samhita'' (सुश्रुतसंहिता, IAST: ''Suśrutasaṃhitā'', literally "Suśruta's Compendium") is an ancient Sanskrit text on medicine and surgery, and one of the most important such treatises on this subject to survive from the ancient world. The ''Compendium of Suśruta'' is one of the foundational texts of Ayurveda (Indian traditional medicine), alongside the '' Charaka-Saṃhitā'', ''the Bheḷa-Saṃhitā'', and the medical portions of the Bower Manuscript. It is one of the two foundational Hindu texts on the medical profession that have survived from ancient India. The ''Suśrutasaṃhitā'' is of great historical importance because it includes historically unique chapters describing surgical training, instruments and procedures which is still followed by modern science of surgery. One of the oldest ''Sushruta Samhita'' palm-leaf manuscripts is preserved at the Kaiser Library, Nepal. History Date Over a century ago, the scholar ...

Dandruff
Dandruff is a skin condition that mainly affects the scalp. Symptoms include flaking and sometimes mild itchiness. It can result in social or self-esteem problems. A more severe form of the condition, which includes inflammation of the skin, is known as seborrhoeic dermatitis. Dandruff in the hair is caused by a fungus called “ Malassezia Globosa” which eats the oil present on the head and when the oil breaks down produce a new substance, “oleic acid”. And many people are allergic to “oleic acid”. And it causes a lot of damage to the skin of the scalp, due to which the skin of the scalp starts falling off a lot. In this, as the layers of damaged skin are continually replaced, the cells are pushed outwards where they die and fall off. The cause is unclear, but believed to involve a number of genetic and environmental factors; the condition may worsen in the winter. It is not due to poor hygiene, and the underlying mechanism involves the excessive growth of skin cel ...
