Magnolia: A plant genus of the family MAGNOLIACEAE. The germacranolide sesquiterpene lactones costunolide, parthenolide, and costunolide diepoxide have been isolated from the leaves. Bark contains honokiol and magnolol. Parts are an ingredient of Banxia Houpo Tang.Lignans: A class of dibenzylbutane derivatives which occurs in higher plants and in fluids (bile, serum, urine, etc.) in man and other animals. These compounds, which have a potential anti-cancer role, can be synthesized in vitro by human fecal flora. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)Magnoliaceae: A plant family of the order Magnoliales, subclass Magnoliidae, class Magnoliopsida. They are trees and shrubs having an elongated conelike floral axis with fragrant flowers that have six tepals (sepals and petals that are not distinctly different) and many spirally arranged stamens.Biphenyl CompoundsPlant Bark: The outer layer of the woody parts of plants.Nasal Sprays: Pharmacologic agents delivered into the nostrils in the form of a mist or spray.Phellodendron: A plant genus of the family RUTACEAE.

The lingual nerve carries general afferent fibers from the anterior two-thirds of the tongue, the floor of the mouth, and the mandibular gingivae.Sympathetic Nervous System: The thoracolumbar division of the autonomic nervous system. Sympathetic preganglionic fibers originate in neurons of the intermediolateral column of the spinal cord and project to the paravertebral and prevertebral ganglia, which in turn project to target organs. The sympathetic nervous system mediates the body's response to stressful situations, i.e., the fight or flight reactions. It often acts reciprocally to the parasympathetic system.Face: The anterior portion of the head that includes the skin, muscles, and structures of the forehead, eyes, nose, mouth, cheeks, and jaw.Blood Flow Velocity: A value equal to the total volume flow divided by the cross-sectional area of the vascular bed.Cerebrovascular Circulation: The circulation of blood through the BLOOD VESSELS of the BRAIN.Laser-Doppler Flowmetry: A method of non-invasive, continuous measurement of MICROCIRCULATION. The technique is based on the values of the DOPPLER EFFECT of low-power laser light scattered randomly by static structures and moving tissue particulates.Chrysanthemum: A plant genus of the family ASTERACEAE. The common names of daisy or marguerite are easily confused with other plants. Some species in this genus have been reclassified to TANACETUM.Gentianaceae: A plant family of the order Gentianales, subclass Asteridae, class Magnoliopsida.Pachytene Stage: The stage in the first meiotic prophase, following ZYGOTENE STAGE, when CROSSING OVER between homologous CHROMOSOMES begins.Flowers: The reproductive organs of plants.Microclimate: The climate of a very small area.Chrysanthemum cinerariifolium: A plant species of the genus CHRYSANTHEMUM, family ASTERACEAE. The flowers contain PYRETHRINS, cinerolones, and chrysanthemines which are powerful contact insecticides. Most in the old Pyrethrum genus are reclassified to TANACETUM; some to other ASTERACEAE genera.Latin America: The geographic area of Latin America in general and when the specific country or countries are not indicated. It usually includes Central America, South America, Mexico, and the islands of the Caribbean.Organic Agriculture: Systems of agriculture which adhere to nationally regulated standards that restrict the use of pesticides, non-organic fertilizers, genetic engineering, growth hormones, irradiation, antibiotics, and non-organic ANIMAL FEED.Plant Oils: Oils derived from plants or plant products.Spices: The dried seeds, bark, root, stems, buds, leaves, or fruit of aromatic plants used to season food.Iridoids: A type of MONOTERPENES, derived from geraniol. They have the general form of cyclopentanopyran, but in some cases, one of the rings is broken as in the case of secoiridoid. They are different from the similarly named iridals (TRITERPENES).Food, Organic: Food that is grown or manufactured in accordance with nationally regulated production standards that include restrictions on the use of pesticides, non-organic fertilizers, genetic engineering, growth hormones, irradiation, antibiotics, and non-organic ingredients.Phenols: Benzene derivatives that include one or more hydroxyl groups attached to the ring structure.Onions: Herbaceous biennial plants and their edible bulbs, belonging to the Liliaceae.Beauty: Characteristics or attributes of persons or things which elicit pleasurable feelings.Beauty CultureTransposases: Enzymes that recombine DNA segments by a process which involves the formation of a synapse between two DNA helices, the cleavage of single strands from each DNA helix and the ligation of a DNA strand from one DNA helix to the other. The resulting DNA structure is called a Holliday junction which can be resolved by DNA REPLICATION or by HOLLIDAY JUNCTION RESOLVASES.Myocardial Reperfusion: Generally, restoration of blood supply to heart tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. Reperfusion can be induced to treat ischemia. Methods include chemical dissolution of an occluding thrombus, administration of vasodilator drugs, angioplasty, catheterization, and artery bypass graft surgery. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing MYOCARDIAL REPERFUSION INJURY.DNA Transposable Elements: Discrete segments of DNA which can excise and reintegrate to another site in the genome. Most are inactive, i.e., have not been found to exist outside the integrated state. DNA transposable elements include bacterial IS (insertion sequence) elements, Tn elements, the maize controlling elements Ac and Ds, Drosophila P, gypsy, and pogo elements, the human Tigger elements and the Tc and mariner elements which are found throughout the animal kingdom.Thrombectomy: Surgical removal of an obstructing clot or foreign material from a blood vessel at the point of its formation. Removal of a clot arising from a distant site is called EMBOLECTOMY.Polypropylenes: Propylene or propene polymers. Thermoplastics that can be extruded into fibers, films or solid forms. They are used as a copolymer in plastics, especially polyethylene. The fibers are used for fabrics, filters and surgical sutures.Mineral Waters: Water naturally or artificially infused with mineral salts or gases.Talc: Finely powdered native hydrous magnesium silicate. It is used as a dusting powder, either alone or with starch or boric acid, for medicinal and toilet preparations. It is also an excipient and filler for pills, tablets, and for dusting tablet molds. (From Merck Index, 11th ed)Powders: Substances made up of an aggregation of small particles, as that obtained by grinding or trituration of a solid drug. In pharmacy it is a form in which substances are administered. (From Dorland, 28th ed)Minerals: Native, inorganic or fossilized organic substances having a definite chemical composition and formed by inorganic reactions.
