Radix Pseudostellariae
''Pseudostellaria heterophylla'', known commonly as ''hai er shen'' (, kid ginseng, child ginseng), ''tai zi shen'' (, crown prince ginseng), and false starwort, is an adaptogen in the family Caryophyllaceae that is used in Chinese medicine and herbalism to tonify the qi and generate yin fluids. It is known as the "ginseng of the lungs". The plant is a low growing plant of the pink family that is grown in Southern China in the provinces of Jiangsu, Anhui, Shandong, Heilongjiang, Jilin, Liaoning, Hebei, Henan, Shaanxi, Zhejiang, Jiangxi, Hubei, and Shanxi. Ethnobotany ''Haiershen'' is a relatively recent addition to the ''Chung Yao Chi New Chinese Materia Medica'' (), having been officially added in 1959, based upon local and ethnic use. It is weaker than ''Panax ginseng''. The herb is a mild adaptogen, demulcent, an immune tonic, nutritive, and a pectoral herb. In Chinese terms it tonifies the yin. Accordingly, the herb is restorative for lung damage due to excess heat or dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adaptogen
Adaptogens or adaptogenic substances are used in herbal medicine for the claimed stabilization of physiological processes and promotion of homeostasis. History The concept of adaptogens was originally created in 1947 to describe a substance that may increase resistance to stress. The term "adaptogenesis" was later applied in the former Soviet Union to describe remedies thought to increase the resistance of organisms to biological stress. Most of the studies conducted on adaptogens were performed in the Soviet Union, Korea, and China before the 1980s. The term was not accepted in pharmacological, physiological, or mainstream clinical practices in the European Union The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been des .... References {{Reflist Herbalism Pharmaceutics ...

Hubei
Hubei (; ; alternately Hupeh) is a landlocked province of the People's Republic of China, and is part of the Central China region. The name of the province means "north of the lake", referring to its position north of Dongting Lake. The provincial capital, Wuhan, serves as a major transportation hub and the political, cultural, and economic hub of central China. Hubei's name is officially abbreviated to "" (), an ancient name associated with the eastern part of the province since the State of E of the Western Zhou dynasty of –771 BCE; a popular name for Hubei is "" () (suggested by that of the powerful State of Chu, which existed in the area during the Eastern Zhou dynasty of 770 – 256 BCE). Hubei borders the provinces of Henan to the north, Anhui to the east, Jiangxi to the southeast, Hunan to the south, Chongqing to the west, and Shaanxi to the northwest. The high-profile Three Gorges Dam is located at Yichang, in the west of the province. Hubei is the 7th-largest p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Respiratory Tract
The respiratory tract is the subdivision of the respiratory system involved with the process of respiration in mammals. The respiratory tract is lined with respiratory epithelium as respiratory mucosa. Air is breathed in through the nose to the nasal cavity, where a layer of nasal mucosa acts as a filter and traps pollutants and other harmful substances found in the air. Next, air moves into the pharynx, a passage that contains the intersection between the oesophagus and the larynx. The opening of the larynx has a special flap of cartilage, the epiglottis, that opens to allow air to pass through but closes to prevent food from moving into the airway. From the larynx, air moves into the trachea and down to the intersection known as the carina that branches to form the right and left primary (main) bronchi. Each of these bronchi branches into a secondary (lobar) bronchus that branches into tertiary (segmental) bronchi, that branch into smaller airways called bronchioles that ev ...

Emphysema
Emphysema, or pulmonary emphysema, is a lower respiratory tract disease, characterised by air-filled spaces ( pneumatoses) in the lungs, that can vary in size and may be very large. The spaces are caused by the breakdown of the walls of the alveoli and they replace the spongy lung parenchyma. This reduces the total alveolar surface available for gas exchange leading to a reduction in oxygen supply for the blood. Emphysema usually affects the middle aged or older population because it takes time to develop with the effects of tobacco smoking, and other risk factors. Alpha-1 antitrypsin deficiency is a genetic risk factor that may lead to the condition presenting earlier. When associated with significant airflow limitation, emphysema is a major subtype of chronic obstructive pulmonary disease (COPD), a progressive lung disease characterized by long-term breathing problems and poor airflow. Without COPD, the finding of emphysema on a CT lung scan still confers a higher mortality r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dry Cough
A cough is a sudden expulsion of air through the large breathing passages that can help clear them of fluids, irritants, foreign particles and microbes. As a protective reflex, coughing can be repetitive with the cough reflex following three phases: an inhalation, a forced exhalation against a closed glottis, and a violent release of air from the lungs following opening of the glottis, usually accompanied by a distinctive sound. Frequent coughing usually indicates the presence of a disease. Many viruses and bacteria benefit, from an evolutionary perspective, by causing the host to cough, which helps to spread the disease to new hosts. Most of the time, irregular coughing is caused by a respiratory tract infection but can also be triggered by choking, smoking, air pollution, asthma, gastroesophageal reflux disease, post-nasal drip, chronic bronchitis, lung tumors, heart failure and medications such as angiotensin-converting-enzyme inhibitors (ACE inhibitors). Treatment should t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheezing
A wheeze is a continuous, coarse, whistling sound produced in the respiratory airways during breathing. For wheezes to occur, some part of the respiratory tree must be narrowed or obstructed (for example narrowing of the lower respiratory tract in an asthmatic attack), or airflow velocity within the respiratory tree must be heightened. Wheezing is commonly experienced by persons with a lung disease; the most common cause of recurrent wheezing is asthma, though it can also be a symptom of lung cancer, congestive heart failure, and certain types of heart diseases. The differential diagnosis of wheezing is wide, and the reason for wheezing in a given patient is determined by considering the characteristics of the wheezes and the historical and clinical findings made by the examining physician. Characteristics Wheeze Wheezes occupy different portions of the respiratory cycle depending on the site of airway obstruction and its nature. The fraction of the respiratory cycle during ...

Bacterial Pneumonia
Bacterial pneumonia is a type of pneumonia caused by bacterial infection. Types Gram-positive ''Streptococcus pneumoniae'' () is the most common bacterial cause of pneumonia in all age groups except newborn infants. ''Streptococcus pneumoniae'' is a Gram-positive bacterium that often lives in the throat of people who do not have pneumonia. Other important Gram-positive causes of pneumonia are '' Staphylococcus aureus'' () and '' Bacillus anthracis''. Gram-negative Gram-negative bacteria are seen less frequently: ''Haemophilus influenzae'' (), ''Klebsiella pneumoniae'' (), ''Escherichia coli'' (), ''Pseudomonas aeruginosa'' (), ''Bordetella pertussis'', and ''Moraxella catarrhalis'' are the most common. These bacteria often live in the gut and enter the lungs when contents of the gut (such as vomit or faeces) are inhaled. Pneumonia caused by ''Yersinia pestis'' is usually called pneumonic plague. Atypical Atypical bacteria causing pneumonia are ''Coxiella burnetii'', ''Chlam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bronchitis
Bronchitis is inflammation of the bronchi (large and medium-sized airways) in the lungs that causes coughing. Bronchitis usually begins as an infection in the nose, ears, throat, or sinuses. The infection then makes its way down to the bronchi. Symptoms include coughing up sputum, wheezing, shortness of breath, and chest pain. Bronchitis can be acute or chronic. Acute bronchitis usually has a cough that lasts around three weeks, and is also known as a chest cold. In more than 90% of cases the cause is a viral infection. These viruses may be spread through the air when people cough or by direct contact. A small number of cases are caused by a bacterial infection such as ''Mycoplasma pneumoniae'' or ''Bordetella pertussis''. Risk factors include exposure to tobacco smoke, dust, and other air pollution. Treatment of acute bronchitis typically involves rest, paracetamol (acetaminophen), and nonsteroidal anti-inflammatory drugs (NSAIDs) to help with the fever. Chronic bronchi ...

Pleurisy
Pleurisy, also known as pleuritis, is inflammation of the membranes that surround the lungs and line the chest cavity (pleurae). This can result in a sharp chest pain while breathing. Occasionally the pain may be a constant dull ache. Other symptoms may include shortness of breath, cough, fever, or weight loss, depending on the underlying cause. The most common cause is a viral infection. Other causes include bacterial infection, pneumonia, pulmonary embolism, autoimmune disorders, lung cancer, following heart surgery, pancreatitis and asbestosis. Occasionally the cause remains unknown. The underlying mechanism involves the rubbing together of the pleurae instead of smooth gliding. Other conditions that can produce similar symptoms include pericarditis, heart attack, cholecystitis, pulmonary embolism, and pneumothorax. Diagnostic testing may include a chest X-ray, electrocardiogram (ECG), and blood tests. Treatment depends on the underlying cause. Paracetamol (acetaminop ...

Asthma
Asthma is a long-term inflammatory disease of the airways of the lungs. It is characterized by variable and recurring symptoms, reversible airflow obstruction, and easily triggered bronchospasms. Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. These may occur a few times a day or a few times per week. Depending on the person, asthma symptoms may become worse at night or with exercise. Asthma is thought to be caused by a combination of genetic and environmental factors. Environmental factors include exposure to air pollution and allergens. Other potential triggers include medications such as aspirin and beta blockers. Diagnosis is usually based on the pattern of symptoms, response to therapy over time, and spirometry lung function testing. Asthma is classified according to the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow rate. It may also be classified as atopic or non-atopic, ...

Nutritive
Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It provides organisms with nutrients, which can be metabolized to create energy and chemical structures. Failure to obtain sufficient nutrients causes malnutrition. Nutritional science is the study of nutrition, though it typically emphasizes human nutrition. The type of organism determines what nutrients it needs and how it obtains them. Organisms obtain nutrients by consuming organic matter, consuming inorganic matter, absorbing light, or some combination of these. Some can produce nutrients internally by consuming basic elements, while some must consume other organisms to obtain preexisting nutrients. All forms of life require carbon, energy, and water as well as various other molecules. Animals require complex nutrients such as carbohydrates, lipids, and proteins, obtaining them by consuming other organisms. Humans have developed agriculture and cooking to ...
