Acupuncture is a traditional Chinese healing method used to relieve pain and discomfort. It is based on the principle of Qi ( "chee"), which defines the flow of energy along the 12 meridians of the body. By inserting needles into pressure points, acupuncturists or try to restore "balance" our energy flow. The exact origin of acupuncture are not known, but the methodology was probably developed around 8000 years in China.

In the Yellow River region of China about 8,000 years ago, the wisdom was especially coveted. Many scholars who think about the energy flow within and outside the body. A wise man by the name of Fu Hsi is believed to have developed the first two symbols of traditional Chinese medicine, representing the creation and reception. These symbols are shown by solid and broken line and later became known as yin and yang. These symbols became the foundation of traditional Chinese medicine. The interaction of yin and yang describes life, and their merger creates a third force. Fu Hsi developed his theory around eight appearances this tripling in the I Ching, also known as the Book of Change.

The development of acupuncture needles
In early Chinese history, primitive stone knives were used for medicinal purposes. Over time, these sheets were formed into thin needles used for healing. These needles are known as the stone Bian. Archaeological excavations have been several bian remains, dating back thousands of years. Finally, these needles are made of bone. It was not until the second century BC were made of metal needles. (Acupuncture needles of gold and silver were discovered in a tomb in China dating back to 113 BC). Annals older drugs mentioned nine different types of needles. Today, most are made of metal and must be sterilized before use.

Significant texts relating to the history of acupuncture
Apart from the I Ching, the Nei Jing is believed to be one of the earliest manuscripts of traditional Chinese medicine. The manuscripts were collected during the period of 305 and 204 BC C. following discussions between the emperor of the time, Huang Di and his physician Qi Bo. Their discussions focused on the art of healing. The Nei Jing is composed of two parts: Su Wen, or normal questions and the Ling Shu, translated in the sense of the miraculous spiritual, and the axis of articulation. The Su Wen is composed of 81 chapters and covers the anatomy, disease etiology, pathology, physiology, diagnosis, differentiation of syndromes, prevention, treatment, and an introduction to the yin and yang and man's relationship with the universe. The Ling Shu focuses mainly on acupuncture meridians in the human body, the functions of Zang-Fu organs and various acupuncture points, nine types of needles, acupuncture techniques, and types of Qi.

Between 421 and 221 BC C. another manuscript called Nan Jing or Book of the tough questions, was written, but focuses on the theory of five elements, with eight additional meridians, and discusses various topics such as diagnosis hara.

Huang Fu Mi was a respected practitioner of traditional medicine that between 260 and 265 AD, compiled a book based on ancient manuscripts called systematic Classics of acupuncture and moxibustion. In its 12 volumes, the text speaks extensively about 349 points of acupuncture, channeling energy and related issues.

Between 265 and 908 AD, the interest and development of acupuncture grew. Many texts have been added, and new models of meridians and pressure points are created. These texts theories and methodologies of acupuncture further refined.

Rise and Fall of acupuncture
Between 1644 and 1840 AD, herbal medicine acupuncture beat as a preferred method of healing. Acupuncture survived as a treatment used by the lower classes, but Chinese scholars who frowned. In 1911, after the Revolution, Western medicine flourished in China, acupuncture was more subdued. But in the Long March of 1934 and 1935, Chinese troops were treated only with acupuncture. This led to praise Mao General of acupuncture as an important part of Chinese culture, and his enthusiasm reintroduced to much of the country. The science of acupuncture is still evolving, and today China has many leading laboratories continued research on this ancient art.You not have to be interested in yoga or acupuncture in order to use carpet Yantra.

Traditional Chinese medicine New process plant extracts
Recent decades, the production of Chinese herbal medicine to achieve a certain degree of mechanization and semi-mechanization. Traditional Chinese medicine is often considered low content of active ingredients, impurities, unstable and therefore more established drugs based on the experience, not integration with modern medicine. To address this problem, traditional Chinese medicine must take the road of extraction and purification. Chinese medicine extraction, including extraction, clarification, filtration and evaporation, and many of the unit operation. Leaching is a very important unit operation, is the starting point for the majority of traditional Chinese medicine production.

Extraction technology is good or bad, is directly related to Chinese herbal medicines Utilization and ease of subsequent processing. Leaching can be seen as an important part of modern Chinese medicine production, and therefore the study and optimize the leaching process of Chinese medicine is necessary.

1 gene principles, and factors Chinese medicine is the solvent leaching into the medicine, the active ingredients to the liquid phase transfer from the group process. Is generally believed that active ingredients in herbal medicines is to determine the leaching rate of the spread of the main steps. The main factors affecting extraction solvent, temperature, pressure, size of material of solid and liquid flow status.

Solvent polarity, viscosity and other properties of plant tissues affected the leaching rate of different substances and dissolution. Water and ethanol are the most commonly used solvent, the two solutions to mix a great influence on the leaching of Chinese herbal medicines.

Temperature and pressure rise, spread faster and also speed up the leaching rate. But the temperature is too high may damage heat-sensitive components. Decoction used in traditional Chinese medicine production is carried out under atmospheric pressure boiling point. But there are also reports that the decompression operation will help improve water herbs to eat, to loose tissue and is conducive to leaching.

The smaller size of material, BET surface area, the faster leaching. But the size is too small will increase the leaching of impurities, separation and purification difficult. The higher rate of relative motion of solid to liquid, the solution the more intense turbulence will lead to boundary layer thinning, update to speed up and improve the leaching rate. Research and results

2 2.1 Optimization of the traditional process and equipment innovations
For Chinese extract Process energy consumption large, impurities and low efficiency of state in recent years, many scholars from different angles on the Chinese extracting process was trial and error and optimization, while maintaining "Chinese characteristics" under the premise of the progressive realization of proprietary Chinese medicines manufactured scientific, standardized, and standardization.

Traditional process is through mass production and testing of clinical practice, and theory of very close contact. Optimization of the traditional benefits available to the most direct, the work has been mostly concentrated in this area. When experts to extract pH, extraction time, when the pH is variable acidification, alkaline extraction of the CSC has been optimized. Found that when the pH value of extracting the effect on the maximum extraction, extraction time and the impact of acidification when the pH value was not significant. Coarse-grained experts glycyrrhizin preparation conditions were optimized, given the juice volume and acidity in acid than the old process of new high technology, while the impregnation time of the original process only 1 / 12, to close slaughter also improved significantly.

Expert on water extraction, water extraction and alcohol precipitation, diluted alcohol extract and water extract of lime precipitation was prepared Honeysuckle Extract A comparative study, found that dilute aqueous alcohol extraction efficiency compared with nearly 40%, both of which consume 18 times the volume of solvent, time-consuming 4h. Alcohol precipitation: France recyclable chlorogenic acid 90%, far better than the yield of milk of lime precipitation, mainly due to the alkaline hydrolysis of chlorogenic acid, and precipitation at the same time not completely, precipitating agent on the product have adsorption also has a relationship.

Zhang Yonghong, etc. of different extraction conditions in the anthraquinone of rhubarb extract the content. Different concentrations of ethanol extract of total anthraquinone, free anthraquinone, anthraquinone, the contents of combining alcohol concentration on a linear regression. Combined with the percentage found in anthraquinone content and concentration of alcohol has some correlation with the increase of ethanol concentration are slightly increasing trend, while anthraquinones with little change in ethanol concentration. Ethanol is better than water extraction. As long heating some anthraquinone will be destroyed, boiling time can not be too long.
