Cistanche Deserticola
''Cistanche deserticola'' is a holoparasitic member of the plant family Orobanchaceae, commonly known as desert-broomrape. The plant lacks chlorophyll and obtains its nutrients and water in a parasitic fashion from the black saxaul (''Haloxylon ammodendron'') and white saxaul (''Haloxylon persicum''). Description ''Cistanche deserticola'' is a perennial hardy, shrub-like herb tall. It is shaped somewhat like a cross between a pine cone and a pineapple, with thick, fleshy stems and large, yellow flowers that grow smaller at the plant's apex. Distribution ''Cistanche deserticola'' is widely distributed in China's deserts including the provinces of Gansu, Shaanxi, and Qinghai, and the Autonomous Regions of Xinjiang, Ningxia, and Inner Mongolia. Traditional uses Along with other members of the genus ''Cistanche'', ''Cistanche deserticola'' is a noted source of the Chinese herbal medicine cistanche (), commonly called Rou Cong Rong.

Chinese Herbal Medicine
Chinese herbology () is the theory of traditional Chinese herbal therapy, which accounts for the majority of treatments in traditional Chinese medicine (TCM). A ''Nature'' editorial described TCM as "fraught with pseudoscience", and said that the most obvious reason why it has not delivered many cures is that the majority of its treatments have no logical mechanism of action. The term herbology is misleading in the sense that, while plant elements are by far the most commonly used substances, animal, human, and mineral products are also utilized, among which some are poisonous. In the ''Huangdi Neijing'' they are referred to as () which means toxin, poison, or medicine. Paul U. Unschuld points out that this is similar etymology to the Greek ''pharmakon'' and so he uses the term "pharmaceutic". Thus, the term "medicinal" (instead of herb) is usually preferred as a translation for (). Research into the effectiveness of traditional Chinese herbal therapy is of poor quality and ...

Flora Of Xinjiang
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurman ...

CITES
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working lang ...

Cistanche
''Cistanche'' is a worldwide genus of holoparasitic desert plants in the family Orobanchaceae. They lack chlorophyll and obtain nutrients and water from the host plants whose roots they parasitize. They are often known as desert hyacinths. Taxonomy There are between 20 and 30 species of ''Cistanche''. The most comprehensive description of the genus was published in 1930. The taxonomy is difficult because important features of the flowers are often poorly preserved after drying. The plants are found from the Mediterranean region, North Africa, Middle East through to China. The species of ''Cistanche'' are parasitic plants that connect to the conductive system of a host, extracting water and nutrients from the roots of the host plant. Growth They typically grow in desert or sand dune areas Growing in arid regions, where their flower spikes that emerge from bare ground are the only evidence of the presence of the plants. They do not have leaves and do not perform photosynthesis. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inner Mongolia
Inner Mongolia, officially the Inner Mongolia Autonomous Region, is an autonomous region of the People's Republic of China. Its border includes most of the length of China's border with the country of Mongolia. Inner Mongolia also accounts for a small section of China's border with Russia (Zabaykalsky Krai). Its capital is Hohhot; other major cities include Baotou, Chifeng, Tongliao, and Ordos. The autonomous region was established in 1947, incorporating the areas of the former Republic of China provinces of Suiyuan, Chahar, Rehe, Liaobei, and Xing'an, along with the northern parts of Gansu and Ningxia. Its area makes it the third largest Chinese administrative subdivision, constituting approximately and 12% of China's total land area. Due to its long span from east to west, Inner Mongolia is geographically divided into eastern and western divisions. The eastern division is often included in Northeastern China (Dongbei) with major cities including Tongliao, Chifeng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obligate Parasite
An obligate parasite or holoparasite is a parasitic organism that cannot complete its life-cycle without exploiting a suitable host. If an obligate parasite cannot obtain a host it will fail to reproduce. This is opposed to a facultative parasite, which can act as a parasite but does not rely on its host to continue its life-cycle. Obligate parasites have evolved a variety of parasitic strategies to exploit their hosts. Holoparasites and some hemiparasites are obligate. It is advantageous for the parasite to preserve the health of their host when this is compatible with their nutritional and reproductive requirements, except when the death of the host is necessary for transmission.Combes, C. (1997) Fitness of Parasites: Pathology and Selection ''International Journal for Parasitology'' 27 (1): 1–10. Species Obligate parasitism is exhibited in a range of organisms, with examples in viruses, bacteria, fungi, plants, and animals.Balashov, Yu.S. (2011) Parasitism and Ecological ...
