Abstract

The invention provides eye drops. The eye drops are prepared by the following steps in accordance with a conventional method: soaking the following medicinal materials in water which is 10 times as much as the total weight of the medicinal materials for 0.5h: 10g of fruits of Chinese wolfberry, 10g of arillus longan, 10g of fruits of Chinese magnoliavine, 15g of semen plantaginis, 6g of poria with hostwood, 6g of radix polygalae, 10g of radix ophiopogonis, 3g of radix polygonati officinalis, 30g of radix angelicae sinensis, 10g of radix bupleuri, 10g of folium mori, 10g of caulis perllae, 10g of poria, 10g of Chinese waxgourd peels, 10g of radix puerariae and 10g of coix seeds; decocting the medicinal materials for 1h; conducting filtering; adding water which is 8 times as much as the total weight of the medicinal materials to dregs and conducting decocting for 1h; filtering medicine liquid, combining two times of decoction, and conducting concentrating until relative density is 1.05 at 60 DEG C; adding ethanol until the volume percentage of an alcohol content is 75%; conducting stirring, standing by and filtering; concentrating a filtrate until relative density is 1.25 at 65 DEG C, and recovering ethanol, so that a concentrated solution is obtained; conducting supercritical extraction, so that a supercritical extract is obtained; continuing to conduct concentrating; and drying a concentrated solution. The prepared eye drops are high in content of ferulic acid.
