Prehistoric Medicine
Prehistoric medicine is any use of medicine from before the invention of writing and the documented history of medicine. Because the timing of the invention of writing varies per culture and region, the term "prehistoric medicine" encompasses a wide range of time periods and dates. The study of Prehistory, prehistoric medicine relies heavily on Artifact (archaeology), artifacts and Cadaver, human remains, and on anthropology. Previously uncontacted peoples and certain indigenous peoples who live in a traditional way have been the subject of anthropological studies in order to gain insight into both contemporary and ancient practices. Disease and mortality Some diseases and ailments were more common in prehistory than they are today; there is evidence that many people suffered from osteoarthritis, probably caused by the lifting of heavy objects which would have been a daily and necessary task in their societies. For example, the transport of latte stones, a practice started du ...

Spondylolysis
Spondylolysis also known as a pars defect or pars fracture, is a defect or stress fracture in the pars interarticularis of the vertebral arch. The vast majority of cases occur in the lower lumbar vertebrae (L5), but spondylolysis may also occur in the cervical vertebrae.Dubousset, J. Treatment of Spondylolysis and Spondylolisthesis in Children and Adolescents. Clinical Orthopaedics and Related Research. 1997;337:77–85. Signs and symptoms In majority of cases, spondylolysis presents asymptomatically, which can make diagnosis both difficult and incidental. When a patient does present with symptoms, there are general signs and symptoms a clinician will look for: * Clinical signs:Humphreys, D. "Lecture on Spondylolysis and Spondylolisthesis". [OWL].

Piptoporus Betulinus
''Fomitopsis betulina'' (previously ''Piptoporus betulinus''), commonly known as the birch polypore, birch bracket, or razor strop, is a common bracket fungus and, as the name suggests, grows almost exclusively on birch trees. The brackets burst out from the bark of the tree, and these fruit bodies can last for more than a year. Taxonomy The fungus was originally described by Jean Bulliard in 1788 as ''Boletus betulinus''. It was transferred to the genus '' Piptoporus'' by Petter Karsten in 1881. Molecular phylogenetic studies suggested that the species was more closely related to '' Fomitopsis'' than to ''Piptoporus'', and the fungus was reclassified to ''Fomitopsis'' in 2016. The specific epithet ''betulina'' refers to the genus of the host plant (''Betula''). Common names for the fungus include birch bracket, birch polypore, and razorstrop fungus. Description The fruit bodies (basidiocarps) are pale, with a smooth greyish-brown top surface, while the creamy white under ...

Nomadic
Nomads are communities without fixed habitation who regularly move to and from areas. Such groups include hunter-gatherers, pastoral nomads (owning livestock), tinkers and trader nomads. In the twentieth century, the population of nomadic pastoral tribes slowly decreased, reaching an estimated 30–40 million nomads in the world . Nomadic hunting and gathering—following seasonally available wild plants and game—is by far the oldest human subsistence method known. Pastoralists raise herds of domesticated livestock, driving or accompanying them in patterns that normally avoid depleting pastures beyond their ability to recover. Nomadism is also a lifestyle adapted to infertile regions such as steppe, tundra, or ice and sand, where mobility is the most efficient strategy for exploiting scarce resources. For example, many groups living in the tundra are reindeer herders and are semi-nomadic, following forage for their animals. Sometimes also described as "nomadic" are var ...

Natural Source
A natural product is a natural compound or substance produced by a living organism—that is, found in nature. In the broadest sense, natural products include any substance produced by life. Natural products can also be prepared by chemical synthesis (both semisynthesis and total synthesis and have played a central role in the development of the field of organic chemistry by providing challenging synthetic targets). The term ''natural product'' has also been extended for commercial purposes to refer to cosmetics, dietary supplements, and foods produced from natural sources without added artificial ingredients. Within the field of organic chemistry, the definition of natural products is usually restricted to organic compounds isolated from natural sources that are produced by the pathways of primary or secondary metabolism. Within the field of medicinal chemistry, the definition is often further restricted to secondary metabolites. Secondary metabolites (or specialized metabol ...

Herbs
Herbs are a widely distributed and widespread group of plants, excluding vegetables, with savory or aromatic properties that are used for flavoring and garnish (food), garnishing food, for medicinal purposes, or for fragrances. Culinary use typically distinguishes herbs from spices. ''Herbs'' generally refers to the leafy green or flowering parts of a plant (either fresh or dried), while ''spices'' are usually dried and produced from other parts of the plant, including seeds, Bark (botany), bark, roots and fruits. Herbs have a variety of uses including culinary, medicinal, aromatic and in some cases, spiritual. General usage of the term "herb" differs between culinary herbs and medicinal herbs; in medicinal or spiritual use, any parts of the plant might be considered "herbs", including leaves, roots, flowers, seeds, root bark, inner bark (and Vascular cambium, cambium), resin and pericarp. The word "herb" is pronounced in Commonwealth English, but is standard among American En ...

Vitamin D
Vitamin D is a group of structurally related, fat-soluble compounds responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, along with numerous other biological functions. In humans, the most important compounds within this group are vitamin D3 ( cholecalciferol) and vitamin D2 ( ergocalciferol). Unlike the other twelve vitamins, vitamin D is only conditionally essential, as with adequate skin exposure to the ultraviolet B (UVB) radiation component of sunlight there is synthesis of cholecalciferol in the lower layers of the skin's epidermis. For most people, skin synthesis contributes more than diet sources. Vitamin D can also be obtained through diet, food fortification and dietary supplements. In the U.S., cow's milk and plant-based milk substitutes are fortified with vitamin D3, as are many breakfast cereals. Government dietary recommendations typically assume that all of a person's vitamin D is taken by mouth, given the potential for ...
