Description
Technical Field
The invention relates to the technical field of traditional Chinese medicine extraction, and particularly relates to a fumigating liquid for yin deficiency and damp heat type xerophthalmia and a preparation method thereof.
Background
Dry eye syndrome (dry-eye syndrome), also known as keratoconjunctival xerosis (KCS), is a general term for a variety of diseases characterized by ocular surface disorders due to decreased tear film stability caused by abnormalities in tear quality and quantity or kinetics, accompanied by ocular discomfort. Epidemiological and clinical studies have found that the incidence of dry eye is increasing. The western medicine treatment methods are various, wherein the tear substitution therapy is a main medicine for treating xerophthalmia at present due to convenient use, definite curative effect and small side effect, but no artificial tear liquid can completely accord with the components of the tear, and the preservative in the artificial tear, especially benzalkonium chloride, has certain damage to the ocular surface through research verification. Anti-inflammatory drugs are available for short-term treatment of dry eye, but are also associated with corneal epithelial toxicity. Androgens can maintain lacrimal glands and other ocular surface tissues in a non-inflammatory state, down-regulate immune activity, promote protein synthesis, have an amplifying effect on the lacrimal secretion process, and the like, but systemic application of sex hormones may cause more serious side effects. Surgical treatments are also not widely used due to the risks involved. Xerophthalmia due to yin deficiency and damp-heat is shown as follows: dryness, pain, blurred vision, thready and sticky eye gum, foul breath, constipation, dark and short urine, red or marginal tongue with teeth, yellowish or thick and greasy coating, and thready, soft and rapid pulse. The applicant obtains better curative effect for treating xerophthalmia by applying the traditional Chinese medicine in clinical practice for many years. However, the traditional method for extracting the effective components of the traditional Chinese medicine mainly comprises the following steps: impregnation, precooking, reflux extraction, steam distillation, distillation under reduced pressure, sublimation, etc. These methods have the disadvantages of complicated extraction process, low product purity, organic residue, and easy damage to heat-sensitive substances, which can also result in reduction of drug effect of the drugs. Therefore, the fumigation solution for treating yin deficiency and damp heat type xerophthalmia and the preparation method thereof are designed to solve the problems.
