HAY FEVER

  Hay fever is an allergic reaction to a particular pollen. Symptoms like runny nose, stuffy nose, itchy eyes, watery eyes, throat irritation, rough skin,... appear when these pollen flies. Hay fever is an allergic reaction that uses pollen as an allergen (antigen). Lymphocytes, which are one of the immune cells, are roughly divided into Th1 lymphocytes (hereinafter, Th1) and Th2 lymphocytes (hereinafter, Th2). Each has a different role, Th1 mainly works against viruses and bacteria, and Th2 works mainly against food and pollen. In other words, it is Th2 that causes an allergic reaction. It is known that these two lymphocytes have a seesaw-like relationship, and that when Th1 is high, Th2 is low, and when Th2 is high, Th1 is low. When allergies such as pollinosis occur, the balance between the two is lost and Th2 increases. The cause of the imbalance is not well understood, but it is said that it is highly possible that lifestyles such as stress and disordered eating habits have an effect. The mechanism by which allergies occur is as follows. When Th2 detects allergens such as pollen, house dust, and mites, it conveys that information to mast cells, which store various chemical messengers. Mast cells that receive the information release chemical mediators such as histamine and leukotrienes. When these histamine and leukotrienes work on the sensory nerves of the nose and eyes, various symptoms peculiar to pollinosis occur. The most important thing in treating hay fever is not to hit (expose) pollen. If the symptoms still do not improve, medication may be given. Currently, the most commonly used drugs are antihistamines and antiallergic drugs. Both are drugs that block histamine released from mast cells. This medicine is effective for histamine-induced symptoms such as runny nose, watery eyes, itchy eyes, and sneezing. Regarding nasal congestion, there is currently no oral drug that strongly blocks leukotrienes without side effects, and at this stage, taking steroids that suppress Th2 and long-term administration of antibacterial drugs that prevent bacterial infection and prevent worsening of symptoms are available. The problem with anti-histamines and anti-allergic drugs is that, as you know, they tend to get sleepy. Histamine not only causes allergic symptoms, but also has an important function of activating the brain. Therefore, blocking histamine with drugs lowers the level of alertness in the brain, causing drowsiness and drowsiness. Recently, a new type of anti-histamine that has been made to prevent the drug from entering the brain has appeared, but it seems that some people still get sleepy. In addition to drug treatment, laser treatment (burning the mucous membrane of the nose with a laser) and desensitization therapy (putting allergens into the body little by little to make it less likely to cause allergies) are also performed. In the case of Kampo treatment, it is divided into suppressing the symptoms themselves and improving the predisposition to get sick to make the body less prone to illness. This is a treatment policy that is common not only to the treatment of pollinosis but also to many Kampo treatments. In the case of hay fever, it will cure runny nose, stuffy nose, sneezing, etc. and improve allergic constitution. First of all, the symptom of pollinosis is regarded as "abnormal water balance in the body (water poisoning)". Water poisoning is a condition in which there is little water where it is needed and a lot of it accumulates in a specific area. A runny nose and watery eyes are symptoms that result from the accumulation of water in unnecessary places. Nasal congestion also occurs when water accumulates in the mucous membrane of the nose and swells. Some people say that they somehow swell during the period of hay fever, but this is also a manifestation of water poisoning. On the other hand, medical examinations are conducted according to the concept of "Energy, blood, and water", and Chinese medicine is prescribed based on the results. "Ki" is like the so-called energy of life, "blood" is blood, and "water" is water other than blood. The concept of "water poisoning" came out earlier, but this "water" is the same as the "water" of qi, blood, and water. Qi plays a role like power, which circulates blood and water well. In water poisoning, it is thought that there is a problem with "water" and the flow of water is impaired, and at the same time, there is some problem with "ki" that controls the flow of water. Also, depending on the person, there may be a problem with "water" due to an abnormality in "blood". It is to correct these abnormalities of qi, water, and blood so that qi, blood, and water work in a well-balanced manner. In any case, remembering to take Chinese herbs patiently is the most important key to the basic treatment of pollinosis. Recently, Western medical research has been attempted on the effects of Chinese herbs on improving their constitution. Basic research has shown that taking a Chinese herbal medicine reduced Th2 lymphocytes and increased Th1 lymphocytes. In this way, it is gradually confirmed that Chinese herbs improve allergic constitution.
