You are talking about "Bilitong" of Hanzhong Top Pharmaceutical Co., Ltd.-"Anemone nasal spray", and the hygiene license is: Zang Wei Jian Yong Zi No. 2008540000-000027. If so, I suggest you not use it. Spraying on the nose is very breathable. After 4 or 5 hours, your nose will be blocked in an instant. I have used it for half a year, and I am very dependent. Spray once before going to bed at night, and you will wake up in the middle of the night. I have to get up and continue spraying medicine to fall asleep. I can't sleep well every night! There are still two bottles at home, which are no longer needed! I suggest you use Boko or Kang! At least not so dependent!
