With the change of modern work and life style, the popularity of computer and internet, people use their eyes excessively, which leads to the incidence of dry eye syndrome increasing year by year, and the age of onset is gradually younger, becoming a common and frequent disease in modern society. At present, the more common treatment for dry eye is artificial tear replacement therapy, but artificial tears only have the effect of symptomatic treatment, and because they contain preservatives and other excipients, long-term use will lead to the occurrence of dry eye, which becomes a contradiction in the treatment of this disease. In contrast, Chinese medicine has a great advantage in treating this disease, “dry eye” is similar to the Chinese medicine “white astringent disease”, the “review of the Yaohuan” volume 5 cloud: dry astringent unpleasant, miao steam is not comfortable, but because of the water less fluid failure, do not wait for the dry light damage, the disease described The classic Chinese medical text “Huangdi Neijing” laid down the programmatic guiding principles for the treatment of eye diseases: “the eye gets blood and can see”, “the liver opens the orifice in the eye”, pointing out that the key to normal function of the eye is the nourishment of the essence of the five viscera and six internal organs In clinical practice, we also found that patients with dry eyes do not have obvious clinical signs of Qi and blood deficiency, but often suffer from deficiency of liver and kidney yin and inflammation of deficiency fire, resulting in fluid deficiency and astringency of Qi and blood, resulting in a series of symptoms of dry eyes such as dryness, dysfunction and uncomfortable eye grinding. Therefore, in clinical practice, we mainly use the formula of pacifying liver and benefiting essence, together with clearing heat and activating blood, to form the formula of pacifying liver and benefiting essence to be taken orally, together with the fumigation of medicinal liquid to treat dry eyes, the results showed that the effect was better in improving the subjective symptoms of patients, and after statistics, the clinical symptoms of the herbal treatment group itself were significantly better than those before treatment, and had a significant advantage over the positive control group in improving the clinical symptoms, and this advantage was also confirmed in the objective index The improvement was also confirmed by the fact that SIt, BUT and corneal fluorescence staining were significantly better in the Chinese herbal treatment group after its own comparative treatment than before treatment, and also had an improvement effect compared with the positive control group, indicating that Chinese herbal treatment is practically effective in improving tear secretion and tear film stability. According to Kongmen medicine, the salty and cold products of the mesocarpus class are sentient to blood and flesh, good at entering the yin division of the lower jiao, pacifying the liver and benefiting the essence, nourishing the kidney and brightening the eyes, nourishing the yin without hindering the stomach and helping dampness, therefore, the formula applies the mesocarpus class drugs such as raw stone cassia, raw sea clam and mother-of-pearl, together with grain essence grass and wolfberry to nourish the liver and kidney; silver flower, mimosa and chrysanthemum have the effect of clearing lung heat and draining liver wind; salvia, cyperus, northern sage, amber and fresh dendrobium can invigorate the blood and generate fluid, nourish the blood and brighten the eyes.
