Problems solved by technology

Granules and capsules are swallowed, absorbed through the gastrointestinal tract, the first-pass effect of the liver, and the bioavailability is reduced; buccal tablets are slowly released in the oral cavity, exert a long-term effect, and cannot relieve symptoms quickly; nasal drops can directly reach the lesion , to play a quick-acting effect, but because it is not easy to quantify, the liquid is not evenly distributed in the nasal cavity, and it is easy to lose from the nasal cavity, causing throat discomfort, and it is necessary to tilt the head back when administering the drug, especially not suitable for children.

[0006] The patent application No. 99115062 discloses a traditional Chinese medicine compound spray for treating acute pharyngitis and chronic pharyngitis. There are as many as 10 kinds of medicines.
