Agathosma Betulina
''Agathosma betulina'' (previously ''Barosma betulina'') is a flowering plant in the family Rutaceae, native to the lower elevation mountains of western South Africa, where it occurs near streams in fynbos habitats. Growth It is an evergreen shrub growing to tall. The leaves are opposite, rounded, about long and broad, glossy, and fragrant. The flowers are white or pale pink, with five petals; the fruit is a five-parted capsule which splits open to release the seeds. Etymology It is known by the common name round leaf buchu. The very similar plant '' Agathosma crenulata'' (previously ''Barosma crenulata'') is known as the oval leaf buchu, and has been used for the same purposes. The two are chemically distinct, however; for example, ''A. betulina'' contains quercetin-dimethyl ether-glucoside, while ''A. crenulata'' does not. Uses Wild plants of this species are still plentiful but are being harvested faster than they can reproduce. The threat of their becoming scarce has ...

Capsule (fruit)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classif ...

Urinary Tract Infection
A urinary tract infection (UTI) is an infection that affects part of the urinary tract. When it affects the lower urinary tract it is known as a bladder infection (cystitis) and when it affects the upper urinary tract it is known as a kidney infection (pyelonephritis). Symptoms from a lower urinary tract infection include pain with urination, frequent urination, and feeling the need to urinate despite having an empty bladder. Symptoms of a kidney infection include fever and flank pain usually in addition to the symptoms of a lower UTI. Rarely the urine may appear bloody. In the very old and the very young, symptoms may be vague or non-specific. The most common cause of infection is ''Escherichia coli'', though other bacteria or fungi may sometimes be the cause. Risk factors include female anatomy, sexual intercourse, diabetes, obesity, and family history. Although sexual intercourse is a risk factor, UTIs are not classified as sexually transmitted infections (STIs). Kidney ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackcurrant
The blackcurrant (''Ribes nigrum''), also known as black currant or cassis, is a deciduous shrub in the family Grossulariaceae grown for its edible berries. It is native to temperate parts of central and northern Europe and northern Asia, where it prefers damp fertile soils. It is widely cultivated both commercially and domestically. It is winter hardy, but cold weather at flowering time during the spring may reduce the size of the crop. Bunches of small, glossy black fruit develop along the stems in the summer and can be harvested by hand or by machine. Breeding is common in Scotland, Poland, Lithuania, Latvia, Norway, and New Zealand to produce fruit with better eating qualities and bushes with greater hardiness and disease resistance. The raw fruit is particularly rich in vitamin C and polyphenols. Blackcurrants can be eaten raw but are usually cooked in sweet or savoury dishes. They are used to make jams, preserves, and syrups and are grown commercially for the juice mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isomenthone
Menthone is a monoterpene with a minty flavor that occurs naturally in a number of essential oils. ''l''-Menthone (or (2''S'',5''R'')-''trans''-2-isopropyl-5-methylcyclohexanone), shown at right, is the most abundant in nature of the four possible stereoisomers. It is structurally related to menthol, which has a secondary alcohol in place of the carbonyl. Menthone is used in flavoring, perfume and cosmetics for its characteristic aromatic and minty odor. Occurrence Menthone is a constituent of the essential oils of pennyroyal, peppermint, ''Mentha arvensis'', ''Pelargonium'' geraniums, and others. In most essential oils, it is a minor compound; it was first synthesized by oxidation of menthol in 1881 before it was found in essential oils in 1891. Structure and preparation 2-Isopropyl-5-methylcyclohexanone has two asymmetric carbon centers, meaning that it can have four different stereoisomers: (2''S'',5''S''), (2''R'',5''S''), (2''S'',5''R'') and (2''R'',5''R''). The ''S'','' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buchu
''Agathosma'' is a genus of about 140 species of flowering plants in the family Rutaceae, native to the southern part of Africa. Common names include Buchu, Boegoe, Bucco, Bookoo and Diosma. '' Buchu'' formally denotes two herbal species, prized for their fragrance and medicinal use despite their toxicity. In colloquial use however, the term (see Boegoe) is applied to a wider set of fragrant shrubs or substitutes. They are small shrubs and subshrubs, mostly with erect woody stems reaching 30–100 cm tall, but low-growing and prostrate in some species. The leaves are usually opposite, ericoid, often crowded, simple, entire, from 0.5-3.5 cm long. The flowers are produced in terminal clusters, 0.7–2 cm diameter, with five white, pink, red or purple, petals. Many of the species are highly aromatic, and the genus name means "good fragrance". Some species of the genus are used as herbal remedies. Uses Two species of ''Agathosma'' endemic to the Western Cape mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agathosma Crenulata
''Agathosma crenulata'' (previously ''Barosma crenulata'') is a flowering plant in the family Rutaceae, native to the lower elevation mountains of southwestern South Africa, where it occurs near streams in fynbos habitats. It is an evergreen shrub growing to 1.5-2.5 m tall. The leaves are opposite, oval, 15–35 mm long and 7–18 mm broad. The flowers are white or pale pink, with five petals; the fruit is a five-parted capsule which splits open to release the seeds. It is known by the common name oval leaf buchu and has historically been used as a flavoring agent and an herbal remedy. The very similar plant ''Agathosma betulina'' (previously ''Barosma betulina'') is known as the round leaf buchu, and has been used for the same purposes. The plant produces many sweet-smelling white flowers, which attract nectar-drinking insects. It then produces small green fruits. The leaves have traditionally been steeped in brandy, vinegar, and tea water, and are said to relieve gas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...
