If there is congestion and edema or lymphatic follicle hyperplasia, it means that there is inflammation in the throat, which will cause itchy throat. You can take Golden Voice Throat or Watermelon Cream tablets, or you can also take Gamboge and Bingmei tablets, Pudilan Anti-inflammatory Oral Liquid or Blue Scutellaria Oral Liquid for treatment. If the symptoms of itching are not very serious, you can also use fat sea to boil water to drink, which can effectively relieve the symptoms of itchy throat. At this time, if there is no inflammatory manifestation, it is likely that allergies have occurred and it is necessary to go to the hospital to check for allergens and avoid contact with the relevant allergens. In addition, anti-allergy medication is needed for treatment, such as loratadine, paracetamol or cetirizine hydrochloride.
