Embodiment 1
[0040] A spray for treating pharyngitis, which includes the following components in mass percentage: 0.15% of large molecular weight sodium hyaluronate (molecular weight 70WDa), 0.15% of small molecular weight sodium hyaluronate (molecular weight of 9500Da), 1.5% of ectoine, 0.2% γ-aminobutyric acid, 2.5% bellflower extract, 0.6% verbena extract, 1.2% forsythia extract, 0.2% menthol, and the balance is purified water.
[0041] The preparation method is as follows:
[0042] Step 1: Weigh high-molecular-weight sodium hyaluronate and low-molecular-weight sodium hyaluronate, dissolve them in an appropriate amount of purified water, and obtain solution A;
[0043] Step 2: adding ectoine, γ-aminobutyric acid, bellflower extract, verbena extract, and forsythia extract into solution A under stirring, and stirring evenly to obtain solution B;
[0044] Step 3: Add menthol to Tween-80 at a ratio of 1:1 (w:w), and mix well to obtain solution C;
[0045] Step 4: Add solution C to solutio...
Embodiment 2
[0050] Prepare the spray according to the formula and method of Example 1, the difference is: 0.18% of large molecular weight sodium hyaluronate (molecular weight 80WDa), 1.8% of small molecular weight sodium hyaluronate (molecular weight 5000Da), 0.3% of ectoine, γ - 0.8% aminobutyric acid, 1.6% bellflower extract, 0.7% verbena extract, 0.82% forsythia extract, 0.3% menthol, and the balance is purified water. The preparation method is the same as in Example 1.
Embodiment 3
[0052] Prepare the spray according to the formula and method of Example 1, the difference is: 0.2% of large molecular weight sodium hyaluronate (molecular weight 110WDa), 1.0% of small molecular weight sodium hyaluronate (molecular weight of 2500Da), 1.0% of ectoine, γ - 0.6% GABA, 1.8% bellflower extract, 1.2% verbena extract, 0.6% forsythia extract, 0.1% menthol, and the balance is purified water. The preparation method is the same as in Example 1.
