[0026] In one embodiment, the preparation method includes the following steps:
[0027] S01: According to parts by weight, weigh 180-220 parts of ginseng, 130-160 parts of wild chrysanthemum, 90-110 parts of chrysanthemum, 70-90 parts of peppermint, and weigh 380-420 parts of borax, 1600-1850 parts of boric acid;
[0028] S02: adding the other medicinal materials weighed in step S01 except the borax and boric acid into water at 90-100° C. for at least one hot water leaching treatment, and filtering and collecting after the leaching treatment is completed, Obtain filtrate;
[0029] S03: reheat the filtrate obtained in step S02 to boil at 95-100° C., collect the supernatant, and concentrate the supernatant to obtain a concentrated extract;
[0030] S04: Mix the concentrated extract with the borax and boric acid, let stand, collect the supernatant, filter and sterilize the supernatant to obtain the eye drops.
[0031] Specifically, the medicinal materials in the above step S01...
