過敏性體質的人，尤其是很多呼吸係統過敏的人，在中醫的觀點上，主要是肺、脾、腎三髒腑功能失調而造成的。肺主呼吸，肺不耐寒熱，易受外感風寒病邪侵襲而造成皮膚的不適。脾主運化，營養失調亦損傷脾胃，進而因運化代謝的不良，造成水濕水邪聚合而成痰濕病氣，引起對食物的過敏。腎主納氣，調節水分代謝。若腎陽不足，氣納功能不良，水分蒸化亦失調，進而造成皮膚的幹燥、大便的幹硬秘結。
中醫治療過敏的幾個特點：
一補：調和五髒六腑及體液，補益氣血、調和陰陽，加速血液循環代謝，修複營養受損老化的黏膜組織，使五髒六腑恢複年輕態，體液恢複平衡。對於氣虛弱型過敏的人群，臨床表現主要為陣發性鼻癢，噴嚏，流清涕，鼻塞，鼻酸脹較重，四肢乏力，頭昏頭重，飲食不香，大便偏稀，鼻黏膜腫脹明顯，蒼白或灰暗，舌質淡胖邊有齒印，苔白或膩，脈細或弱，治療用益氣健脾法；對於腎陽虧虛型過敏人群，臨床表現主要為陣發性鼻癢，噴嚏頻作，連連不已，鼻流清涕，量多如注，形寒怕冷，腰酸腿軟，小便清長，夜尿頻，舌淡胖，苔白，脈沉細，治療用溫陽補腎法，都有實際療效。
二排：把多年積蓄在五髒六腑及體液內的寒、濕、毒代謝出體外，對於氣虛寒型的患者，臨床表現主要為陣發性鼻癢，噴嚏，流清涕，早晚易發，遇風（寒）即作，怕冷，易感冒，麵色淡白，氣短，咳嗽痰稀，鼻黏膜蒼白水腫，舌質淡，苔白，脈細，治療用溫肺散寒法。
三提：提高人體免疫功能，改善過敏體質，提高人體對各種過敏原的抵抗防禦能力，斬斷過敏原入侵。對於氣虛血瘀型：臨床表現主要為陣發性鼻癢，噴嚏，流清涕，鼻塞明顯、鼻甲紫暗，舌暗紅有瘀點，苔白，脈澀，治療用活血化瘀法。對於外寒內熱型：臨床表現主要為陣發性鼻癢，噴嚏，流清涕，鼻塞，怕冷，遇風易作，口幹，喜冷飲，大便幹結，舌紅苔黃。治療用平調寒熱法，都有實際療效。
An allergy is a hypersensitivity disorder of the immune system.[1] Symptoms include red eyes, itchiness, and runny nose, eczema, hives, or anasthma attack. Allergies can play a major role in conditions such as asthma. In some people, severe allergies to environmental or dietary allergens or tomedication may result in life-threatening reactions called anaphylaxis. Food allergies, and reactions to the venom of stinging insects such as wasps andbees are more often associated with these severe reactions.[2] Not all reactions or intolerances are forms of allergy.[3]
Allergic reactions occur when a person's immune system reacts to normally harmless substances in the environment. A substance that causes a reaction is called an allergen. These reactions are acquired, predictable, and rapid. Allergy is one of four forms of hypersensitivity and is formally called type I (orimmediate) hypersensitivity. Allergic reactions are distinctive because of excessive activation of certain white blood cells called mast cells and basophils by a type of antibody called Immunoglobulin E (IgE). This reaction results in an inflammatory response which can range from uncomfortable to dangerous.
A variety of tests exist to diagnose allergic conditions. If done they should be ordered and interpreted in light of a person's history of exposure as many positive test results do not mean a clinically significant allergy.[4] Tests include placing possible allergens on the skin and looking for a reaction such as swelling and blood tests to look for an allergen-specific IgE.
Treatments for allergies include avoiding known allergens, steroids that modify the immune system in general, and medications such as antihistamines and decongestants which reduce symptoms. Many of these medications are taken by mouth, although epinephrine, which is used to treat anaphylactic reactions, is injected. Immunotherapy uses injected allergens to desensitize the body's response. Mild allergies like hay fever are very common.
From Wikipedia, the free encyclopedia
The immune system is a system of biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthytissue. In many species, the immune system can be classified into subsystems, such as the innate immune system versus the adaptive immune system, orhumoral immunity versus cell-mediated immunity.
Pathogens can rapidly evolve and adapt, and thereby avoid detection and neutralization by the immune system; however, multiple defense mechanisms have also evolved to recognize and neutralize pathogens. Even simple unicellular organisms such as bacteriapossess a rudimentary immune system, in the form ofenzymes that protect against bacteriophage infections. Other basic immune mechanisms evolved in ancient eukaryotes and remain in their modern descendants, such as plants and insects. These mechanisms include phagocytosis, antimicrobial peptides called defensins, and the complement system. Jawed vertebrates, including humans, have even more sophisticated defense mechanisms,[1] including the ability to adapt over time to recognize specific pathogens more efficiently. Adaptive (or acquired) immunity creates immunological memory after an initial response to a specific pathogen, leading to an enhanced response to subsequent encounters with that same pathogen. This process of acquired immunity is the basis of vaccination.
