Experimental example 2
In a mouse staphylococcus aureus infectious wound repair experiment, a wound of a mouse treated by the wound healing lotion prepared in the embodiment 1 and the comparative example 1 of the application is taken as an experimental group, a wound of a mouse treated by normal saline is taken as a negative control group, a mouse in a model group is not treated, the change of the wound area of each group of mice is recorded, and the experimental result is shown in table 2.
The result shows that the wound healing lotion can effectively reduce the area of the wound surface of a mouse infected by staphylococcus aureus or escherichia coli, remarkably improve the shrinkage rate of the wound surface, and has a promoting effect on the healing of the wound surface, wherein the wound healing lotion is characterized in that ulcer is reduced, granulation tissue at the bottom of the ulcer is proliferated and matured, and the regeneration of epithelium at the edge of the ulcer is increased. And the group of the embodiment 1 added with the borax is superior to the group of the comparative example 1 not added with the borax, and has statistical difference with the model group and the negative control group.

Experimental example 3
Stability test, the stability of the product of example 1 and comparative example 1 was examined under the conditions close to the actual storage conditions of the product, and the pH was measured by sampling at 25. + -. 2 ℃ on days 1, 2, 4, 8, 16, 30 and 60, respectively, and the results are shown in FIG. 5.
The results show that as the number of days of storage increased, example 1 showed no sedimentation, substantially no change in pH, and long-term stability. However, in comparative example 1 in which no borax was added, the pH was significantly lowered after storage for about 10 days, and the precipitation phenomenon was observed with the naked eye.
The experimental results show that compared with the wound healing lotion prepared by the prescription added with borax, the wound healing lotion prepared by the invention enhances the stability of the lotion, enhances the bacteriostatic effect of the lotion and has better promotion effect on wound healing.
In summary, the preparation method provided by the application is simple to operate, and the activity of the effective ingredients can be ensured to the maximum extent in the preparation process. The cleaning agent can be used for cleaning the wound surface at the first time after injury to prevent bacterial root implantation and effectively promote the healing of the wound surface.
While there have been shown and described what are at present considered to be the preferred embodiments of the present invention, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. All the components not specified in the present embodiment can be realized by the prior art.
