After the winter solstice, last year’s latent yang energy begins to rise, and spring is approaching, it is the season of allergic diseases, and allergic rhinitis is especially common in the Lingnan area. Especially allergic rhinitis in children. In clinical practice, TCM doctors like to use Cang Er Zi San plus or minus to treat allergic rhinitis, which is still effective but easy to repeat. In fact, the treatment of pediatric allergic rhinitis has its own unique approach, in general, rhinitis is mostly treated from the spleen and lung, the lung is open to the nose, the spleen is the mother of the lung, children’s internal organs are young and tender, the lungs are delicate organs, not resistant to heat and cold and pungency, so like Cang Er Zi, catkins, ephedra and other pungent and sweet products should be used sparingly, more lung and spleen products, so that treatment can last. In the clinic, I more external use and internal use together. Externally borrowed from Biyun San (goose not edible grass 5 grams, Chuanxiong 5 grams, fine pungent 5 grams, catkins 5 grams, Qing Dai 5 grams, ground powder, a little twice daily blowing nose.) The internal use of fresh Huai Shan 50 grams, 50 grams of coix seeds, lily 30 grams of porridge and meat can be, adhere to half a month, the effect is satisfactory!
