3 Claims

1. A liquid dressing for promoting wound healing, consisting of, in percentage by weight:

1% to 2% of monomeric silicic acid and 98% to 99% of distilled water;

wherein the monomeric silicic acid is Si(OH)₄;

wherein the liquid dressing for promoting wound healing is prepared by a method comprising the following steps:

step 1 of sequentially adding the monomeric silicic acid and the distilled water into a reaction kettle according to the composition ratio, and controlling a temperature to a range from 120° C. to 150° C.;

step 2 of performing a stir in the reaction kettle, and keeping the temperature at 100° C. for 1 to 3 hours after the substances in the reaction kettle are completely dissolved;

step 3 of lowering an internal temperature of the reaction kettle to 50° C., and leaving the mixed liquid after being uniformly mixed to stand; and

step 4 of cooling the mixture obtained in the step 3 to room temperature to obtain the liquid dressing.
