[전남인터넷신문]Spring flowers such as forsythia and magnolia are blooming. Pollen season with blooming flowers. Nature presents the scenery of spring flowers in full bloom, but some people suffer from symptoms such as sneezing and runny nose due to the scattering of pollen.
It is important to take countermeasures in order not to aggravate the symptoms of those who have pollen allergy symptoms along with the scattering of pollen. Among the various countermeasures, one that can be easily introduced is to drink green tea. It is known through several studies that green tea helps prevent and relieve symptoms of pollen allergy.
According to the result of a joint research conducted by Itoen Central Research Institute of Japan and Professor Jeong Jong-cheol of Nippon Pharmacy University, ‘catechin’, a type of polyphenol contained in green tea, oolong tea, and black tea, is an anti-allergic drug, It was revealed that it has the same allergy suppression effect as ‘Tranilast’. In addition, it is said that catechins suppress the activation of granule cells involved in inflammation or immune response, thereby suppressing the release of histamine, which is the cause of itching and nasal congestion.
These effects are effective just by drinking green tea beverages containing catechins, and there are differences depending on the variety of tea trees, and oolong tea and jasmine tea are also effective. In an actual study, people suffering from hay fever were asked to consume a tea drink containing catechin per day (3 paper packs of 250mL) and investigated. After continuous drinking for 6 weeks from February to mid-March, as a result of the investigation, symptoms such as sneezing, runny nose, stuffy nose, watery eyes, and itching in the eyes were alleviated, and the frequency of drug use was confirmed.
In the results of this study, it was possible to confirm the control effect of pollen allergy by drinking a tea drink containing about 414 mg of catechin daily. Therefore, as a countermeasure against pollen allergy, it would be good to make it a habit to drink the same amount of green tea or consume more catechin daily, or to drink oolong tea or jasmine tea.
If the effect of suppressing hay fever by drinking green tea is enhanced, catechins are excreted from the body after a certain amount of time even if consumed, so it is important to drink them frequently rather than ingesting them all at once. Also, it is good to drink it when you feel throat pain due to pollen allergy or when you have a cough. Green tea also has a bactericidal effect, so you can easily take care of your throat.
Catechin, which is the most abundant ingredient in green tea, is expected to have three inhibitory effects on influenza in addition to suppressing hay fever. It is an action that inhibits the adsorption of viruses to cells, an action that inhibits entry into cells, an action that inhibits the process of proliferating viruses that have entered cells, and the process of spreading from cells to other cells. In addition to catechin, it is estimated that theanine and vitamin C, which are components of green tea, have an effect of enhancing immunity, and stryctinine has an effect of suppressing the proliferation of viruses.
In fact, in a survey of about 2,600 elementary school students, drinking 1 to 5 cups of green tea a day, 6 days a week or more reduced the incidence of influenza by about 40 to 50%. As a result of comparing the results of brushing teeth with green tea and tap water in 1,100 high school students, it was found that the incidence of influenza was reduced by about 30-50% when brushing teeth with green tea. Therefore, it can be said that drinking tea habitually every day and brushing one’s teeth with green tea contribute to countermeasures against influenza.
In spring, when the flowers bloom, besides hay fever, it is the time to take measures against infectious diseases such as colds and influenza due to temperature changes such as cold in the flower spring. Prepare green tea and green tea drinks from Jeonnam, such as Boseong, and hold green tea in your mouth for a few seconds before swallowing to suppress colds and pollen allergies.
