Ovary care composition containing lotus seed exosome and preparation method thereof

Technical Field

The invention relates to the field of biomedicine. Specifically, the invention relates to an ovary care composition containing lotus seed exosomes and a preparation method thereof.

Background

The ovary is one of the important endocrine glands of women, and its main functions are to secrete female hormones and to produce ova. In recent years, with the increasing social pressure of women, the incidence of premature ovarian failure is increasing year by year due to the influence of various factors such as psychology, sleep, bad life style and environmental pollution. Female infertility is often related to ovaries, and once the ovaries are premature or hypofunction, the premature ovarian failure or hypofunction can cause rapid aging of all parts of the human body. Ovarian hypofunction has a process of onset and progression, where hormone levels may be normal, and Follicle Stimulating Hormone (FSH) may also be normal initially, and then gradually become abnormal. Ovarian diseases are mainly manifested in menstrual periods, and are often manifested as irregular menstruation, which has many different manifestations, such as advanced menstrual period, delayed menstrual period, excessive menstrual blood, scanty menstrual blood, irregular menstrual period, etc.

However, ovarian dysfunction is not irreversible, as long as it is not debilitating, and clinical symptoms can be significantly ameliorated by active treatment. At present, premature ovarian failure is treated mainly by hormone therapy, and patients often need small amount of estrogen or female and progestogen treatment. However, although hormone therapy can eliminate climacteric syndrome on the surface, most people are easy to relapse after drug withdrawal, and the side effects of hormone also bring great burden to the mind and body of patients. In addition, the medicine can regulate endocrine to treat, thereby achieving the effect of improving symptoms. However, the herbs are three-way toxic, especially some Chinese herbs, which can cause heavy load of viscera and affect metabolism of body after long-term administration.

The traditional Chinese medicine composition has the advantages that the traditional Chinese medicine composition is capable of supplementing medicinal and edible traditional Chinese medicine components for nourishing yin, tonifying kidney, enriching blood, tonifying yang, soothing liver, strengthening spleen and stomach, can effectively protect and improve premature ovarian failure of women, improve the function decline of ovarian stores, promote ovarian hyporeaction and the like, adopts a plurality of beneficial components for nourishing liver and kidney, tonifying kidney, replenishing essence, nourishing yin, moistening lung, nourishing qi, enriching blood, promoting the production of body fluid, quenching thirst and the like, plays a role in increasing ovarian reactivity, protecting and improving ovarian function and promoting follicular development, and can benefit people with decreased ovarian stores, premature ovarian failure and the like.
