Herbal Distillates
Herbal distillates, also known as floral waters, hydrosols, hydrolates, herbal waters, and essential waters, are aqueous products of hydrodistillation. They are colloidal suspensions of essential oils as well as water-soluble components obtained by steam distillation or hydrodistillation (a variant of steam distillation) from plants and herbs. These herbal distillates have uses as flavorings and cosmetics. Common herbal distillates for skincare include rose water, orange flower water, and witch hazel. Rosemary, oregano, and thyme are hydrosols that may be used in food manufacturing. Production Herbal distillates are produced in the same or similar manner as essential oils. However, essential oils will float to the top of the distillate where it is removed, leaving behind the watery distillate. For this reason the term ''essential water'' is an apt description. In the past, these essential waters were often considered a byproduct of distillation, but are now considered an imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Topical Medication
A topical medication is a medication that is applied to a particular place on or in the body. Most often topical medication means application to body surfaces such as the skin or mucous membranes to treat ailments via a large range of classes including creams, foams, gels, lotions, and ointments. Many topical medications are epicutaneous, meaning that they are applied directly to the skin. Topical medications may also be inhalational, such as asthma medications, or applied to the surface of tissues other than the skin, such as eye drops applied to the conjunctiva, or ear drops placed in the ear, or medications applied to the surface of a tooth. The word ''topical'' derives from Greek τοπικός ''topikos'', "of a place". Justification Topical drug delivery is a route of administering drugs via the skin to provide topical therapeutic effects. As skin is one of the largest and most superficial organs in the human body, pharmacists utilise it to deliver various dr ...

Herbalism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flavor Technology
Flavor or flavour is either the sensory perception of taste or smell, or a flavoring in food that produces such perception. Flavor or flavour may also refer to: Science *Flavors (programming language), an early object-oriented extension to Lisp * Flavour (particle physics), a quantum number of elementary particles related to their weak interactions *Flavor of Linux, another term for any particular Linux distribution; by extension, "flavor" can be applied to any program or other computer code that exists in more than one current variant at the same time Film and TV * ''Flavors'' (film), romantic comedy concerning Asian-Indian immigrants in America Music Artists and bands *Flavor Flav (born 1959), former rap/hip-hop promoter and current reality television actor *Flavour N'abania (born 1983), Nigerian singer-songwriter * Flavor (band), minor hit with "Sally Had A Party" in 1968 Albums * ''Flavours'' (album), 1975 album by The Guess Who * ''Flavors'' (album), by American R&B ...

Essential Oils
An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is essential in the sense that it contains the essence of the plant's fragrance—the characteristic fragrance of the plant from which it is derived. The term "essential" used here does ''not'' mean indispensable or usable by the human body, as with the terms essential amino acid or essential fatty acid, which are so called because they are nutritionally required by a living organism. Essential oils are generally extracted by distillation, often by using steam. Other processes include expression, solvent extraction, '' sfumatura'', absolute oil extraction, resin tapping, wax embedding, and cold pressing. They are used in perfumes, cosmetics, soap ...

Herbs
In general use, herbs are a widely distributed and widespread group of plants, excluding vegetables and other plants consumed for macronutrients, with savory or aromatic properties that are used for flavoring and 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, 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 as "herbs", including leaves, roots, flowers, seeds, root bark, inner bark (and cambium), resin and pericarp. The word "herb" is pronounced in Commonwealth English, but is c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distillation
Distillation, or classical distillation, is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation, usually inside an apparatus known as a still. Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids); this may involve chemical changes such as destructive distillation or cracking. Distillation may result in essentially complete separation (resulting in nearly pure components), or it may be a partial separation that increases the concentration of selected components; in either case, the process exploits differences in the relative volatility of the mixture's components. In industrial applications, distillation is a unit operation of practically universal importance, but is a physical separation process, not a chemical reaction. An installation used for distillation, especially of distilled beverages, is a distillery. Distillation includes th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rose Water
Rose water ( fa, گلاب) is a flavoured water made by steeping rose petals in water. It is the hydrosol portion of the distillate of rose petals, a by-product of the production of rose oil for use in perfume. Rose water is also used to flavour food, as a component in some cosmetic and medical preparations, and for religious purposes throughout Asia and Europe. Rose syrup (not to be confused with rose hip syrup) is a syrup made from rose water, with sugar added. Gulkand in South Asia is a syrupy mashed rose mixture. Central Iran is home to the annual Golabgiri festival each spring. Thousands of tourists visit the area to celebrate the rose harvest for the production of ''golâb'' (). Iran accounts for 90% of world production of rose water. History Since ancient times, roses have been used medicinally, nutritionally, and as a source of perfume. Rose perfumes are made from rose oil, also called '' attar of roses'', which is a mixture of volatile essential oils obtained ...

Orange Flower Water
Orange flower Orange flower water, or orange blossom water, is a clear aromatic by-product of the distillation of fresh bitter-orange blossoms for their essential oil. Uses This essential water has traditionally been used as an aromatizer in many Mediterranean traditional dessert dishes, such as in France for the gibassier and pompe à l'huile or in Spain for the Roscón de Reyes (King cake), or the Samsa in Tunisia or in Moroccan coffee, but has more recently found its way into other cuisines. For example, orange flower water is used in Europe to flavor madeleines, in Mexico to flavor little wedding cakes and Pan de muerto, and in the United States to make orange blossom scones and marshmallows. Orange flower water is also used as an ingredient in some cocktails, such as the Ramos Gin Fizz. In Malta and many North African as well as Middle Eastern countries, orange blossom water is widely used as medicine for stomach ache and given to small children as well as adults. Or ...

Heavy Metals

The criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic number, while a chemist would likely be more concerned with chemical property, chemical behaviour. More specific definitions have been published, but none of these have been widely accepted. The definitions surveyed in this article encompass up to 96 out of the 118 known chemical elements; only mercury, lead and bismuth meet all of them.
