Prunella Vulgaris
''Prunella vulgaris'', the common self-heal, heal-all, woundwort, heart-of-the-earth, carpenter's herb, brownwort or blue curls, is a herbaceous plant in the mint family Lamiaceae. Self-heal is edible: the young leaves and stems can be eaten raw in salads; the plant as a whole can be boiled and eaten as a leaf vegetable; and the aerial parts of the plant can be powdered and brewed in a cold infusion to make a beverage. Description ''Prunella vulgaris'' grows high, with creeping, self-rooting, tough, square, reddish stems branching at the leaf axes. The leaves are lance-shaped, serrated and reddish at the tip, about long and broad, and growing in opposite pairs down the square stem. Each leaf has 3-7 veins that shoot off the middle vein to the margin. The stalks of the leaves are generally short, but can be up to long. The flowers grow from a clublike, somewhat square, whirled cluster; immediately below this club is a pair of stalkless leaves standing out on either side l ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lingnan Culture
Lingnan culture, or Cantonese culture, refers to the regional Chinese culture of the region of Lingnan: twin provinces of Guangdong and Guangxi, the names of which mean "eastern expanse" and "western expanse" respectively. Strictly speaking, the term "Lingnan culture" has two definitions: #In a purely geographical sense, the term includes not only Cantonese culture but also the cultures of the Hakkas, Teochews, Taishanese, Hainanese and non-Han groups such as the Zhuangs, Tanka or She within the Lingnan region. #More typically, is only used in referring to Cantonese culture, the historically dominant culturo-linguistic force in Guangdong and Guangxi. This article uses the second definition of "Lingnan culture" – as the synonym of "Cantonese culture". With the migration of the Cantonese people to nearby Hong Kong and Macau, as well as in many overseas communities, Lingnan/Cantonese culture has become an influential cultural force in the international community, and forms th ...

Phytochemical
Phytochemicals are chemical compounds produced by plants, generally to help them resist fungi, bacteria and plant virus infections, and also consumption by insects and other animals. The name comes . Some phytochemicals have been used as poisons and others as traditional medicine. As a term, ''phytochemicals'' is generally used to describe plant compounds that are under research with unestablished effects on health, and are not scientifically defined as essential nutrients. Regulatory agencies governing food labeling in Europe and the United States have provided guidance for industry to limit or prevent health claims about phytochemicals on food product or nutrition labels. Definition Phytochemicals are chemicals of plant origin. Phytochemicals (from Greek ''phyto'', meaning "plant") are chemicals produced by plants through primary or secondary metabolism. They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, p ...
