Description

Technical Field

[0001] This invention belongs to the field of tea beverage technology, specifically relating to a health-preserving and conditioning tea and its preparation method. Background Technology

[0002] Due to the fast pace of modern life and high stress levels, many people are in a sub-healthy state. This is especially true for women, whose ovarian health is significantly affected by work and life pressures. As a result, people are starting to learn about health preservation and pay attention to quality of life, with a preference for health-preserving tea products in their diet.

[0003] Current treatments for dysmenorrhea involve blood tests to check hormone levels, supplementing hormones if deficient, and commonly using progesterone. For polycystic ovary syndrome (PCOS), birth control pills such as Marvelon and Indah 35 can be used. However, these medications have significant side effects, and long-term use can lead to endometrial atrophy, premature ovarian failure, and other symptoms, with a low success rate. Therefore, a method with fewer side effects is needed to improve women's dysmenorrhea.

[0004] China has a long tradition of using tea for health and healing. Health-preserving teas are made by carefully blending various medicinal herbs to retain the maximum amount of tea's unique qualities, extracting its flavor and rich nutrients. With their full-bodied and mellow taste and diverse functions, they are ideal natural health and wellness drinks. They are undoubtedly a suitable way to regulate menstrual cramps in women, improve ovarian health, and delay aging. Summary of the Invention

[0072] Proof of effectiveness:

[0073] I. Anti-aging effect test: Healthy wild-type zebrafish with a 3dpf growth rate were divided into two groups: a normal group and a sample group, with 10 zebrafish in each group. The normal group was fed E3 culture water; the sample group was fed the health-preserving tea prepared according to this invention. Both groups were placed in a 28.5℃ biochemical incubator. After 15 days, the zebrafish were transferred to centrifuge tubes, and the extract was added for homogenization. Monoamine oxidase activity was detected using a monoamine oxidase activity assay kit, and protein concentration was detected using a BCA protein assay kit. The results are as follows: Figure 1 As shown.

[0074] II. Anti-ovarian aging test: Using anhydrous ethanol as a co-solvent, sample solutions with concentrations of 0.5 mg / 50 ml and 1 mg / 50 ml were prepared using the concentrated solution prepared in Example 1 of this invention. These solutions were then mixed into equal amounts of feed, and the prepared feed was placed in a fume hood at room temperature to air dry naturally, serving as the sample group feed, labeled as 0.5 mg / 50 ml sample feed and 1 mg / 50 ml sample feed. Finally, the feed was stored in containers at 4°C for later use. The zebrafish were divided into three groups: a control group, sample group 1, and sample group 2, with 15 zebrafish in each group. The control group zebrafish were fed an equal amount of feed mixed with unadulterated anhydrous ethanol. Sample groups 1 and 2 were fed 0.5 mg / 50 ml sample feed and 1 mg / 50 ml sample feed, respectively. All three groups were fed twice daily at the same time, with each feeding amount being 5% of the fish's body weight, for 28 days.

[0075] 2.1 Ovulation function testing

[0076] After the three groups of experiments began, an spawning test was conducted every 3 days. Two fish were randomly selected from each group and spawned with wild-type male fish at a female-to-male ratio of 1:2. The total number of eggs laid and the egg survival rate were then calculated to evaluate the effect of the drug on the number and quality of eggs released by zebrafish.

[0077] 2.2 Histological observation of the ovary

[0078] After the three sets of experiments were completed, a portion of ovarian tissue was collected for histological observation. After collection, the ovarian tissue was fixed in Bouin's solution for 3 days, then dehydrated, embedded, and sectioned. Observation and photographic recording were performed after hematoxylin-eosin staining. The developmental stages of oocytes were analyzed and calculated using ImageJ software.

[0079] The above test results are as follows Figure 2-7 As shown.

[0080] Results analysis:

[0081] Anti-aging analysis: The nucleic acid and amino acid sequences of monoamine oxidase (MAO) share 67%–69% identity with those of mouse and rat MAO, and zebrafish MAO has the same exon-intron structure as human MAO. Inhibiting MAO-B or Bestrophin-1 channels to reduce the production and release of γ-aminobutyric acid (GABA) can reduce neuronal, synaptic transmission, and memory impairment in Alzheimer's disease models.

[0082] This invention Figure 1 The results showed that the monoamine oxidase activity in zebrafish fed with the health-preserving and conditioning tea prepared in this invention was significantly lower than that in zebrafish fed with the normal health-preserving and conditioning tea, proving that the health-preserving and conditioning tea prepared in this invention has the effect of delaying aging.

[0083] 2. Analysis of anti-ovarian aging: combined with Figure 2-4 Compared with the control group, the number of eggs laid, fertilization rate and embryo survival rate of zebrafish in sample groups 1 and 2 were significantly improved, proving that the health-preserving tea prepared by the present invention can delay ovarian aging. When the concentration of the concentrated health-preserving tea of ​​the present invention is 1mg / 50ml, the ovarian health is at its best.
