Description

Technical Field

[0001] This invention belongs to the field of health tea technology, specifically relating to a brewing tea for those with yin deficiency. Background Technology

[0002] For those with Yin deficiency, daily maintenance should focus on replenishing Yin essence. Whether due to congenital insufficiency or acquired malnutrition, individuals with Yin deficiency suffer from a lack of Yin fluids such as body fluids, essence, and blood. "Qi, blood, essence, and body fluids" are the fundamental substances that constitute the human body and promote its growth and development. The *Ling Shu* (Spiritual Pivot) states, "The blood, qi, and spirit of a person are what sustain life and sustain its nature." The *Ling Shu* also specifically discusses the importance of body fluids: "The lifespan of people varies… the six viscera transform grains, and body fluids are distributed. Each follows its proper function, thus enabling longevity." Here, "longevity" refers to a person's lifespan reaching its natural limit, and the distribution of body fluids is a crucial aspect of "reaching one's natural limit," meaning that body fluids must be distributed throughout the body, nourishing all organs and joints. If body fluids are deficient, it will cause dry intestines and constipation, dry throat and dry mouth; if the yin fluids cannot moisten the skin, the skin will become dry and rough, and the face will look haggard and old; if the yin fluids cannot penetrate into the bone cavity and transform into essence and marrow, the marrow sea will be insufficient, resulting in weakness in the legs, tinnitus and dizziness, dry nose and dry eyes.

[0003] People with Yin deficiency constitution have insufficient Yin fluid, resulting in a lack of nourishment and moisture to the body. Simultaneously, due to Yin's inability to control Yang, Yang heat becomes relatively excessive, generating internal heat. Since ancient times, traditional Chinese medicine has been the most effective treatment for people with Yin deficiency. Ancient texts such as the *Suwen* and *Shennong Bencao Jing* record that medicines are classified into superior, medium, and inferior grades. Superior grade medicines are non-toxic and can be taken frequently and for extended periods without harming the body; medium grade medicines are non-toxic or toxic but should be used sparingly to treat illness and replenish deficiencies; inferior grade medicines are highly toxic and cannot be taken long-term, but can dispel cold and heat pathogens and break up accumulations. In modern times, to further regulate the management of raw materials for health food, the Ministry of Health issued the *List of Items That Are Both Food and Medicine* in 2002, based on the *Food Hygiene Law of the People's Republic of China*. Therefore, among medicines effectively treating Yin deficiency, those that are non-toxic, can be taken frequently and for extended periods, and are both food and medicine are the best choices.

[0004] Therefore, this invention selects authentic medicinal herbs from the "List of Items That Are Both Food and Medicine" as raw materials to make a convenient tea for consumption. Summary of the Invention

[0005] To address the problems in the existing technology, this invention selects five authentic medicinal herbs from the "List of Items That Are Both Food and Medicine" as raw materials to provide a safe, effective, non-toxic, convenient, and long-term suitable tea for those with Yin deficiency.

[0006] The technical problem solved by this invention is achieved by the following technical solution:

[0007] The purpose of this invention is to provide a tea for those with Yin deficiency, characterized by being composed of the following ingredients: 2-10 grams of kudzu root, 1-15 grams of yam, 1-10 grams of reed rhizome, 1-10 grams of Solomon's seal rhizome, and 2-10 grams of lily bulb. The mass ratio of kudzu root to yam is 2:2.4-3.0, and the mass ratio of reed rhizome, Solomon's seal rhizome, and lily bulb is 3:3.3-3.7:4.5-5.5.

[0008] Furthermore, a tea for those with Yin deficiency is composed of the following ingredients: 2-5 grams of kudzu root, 3-6 grams of yam, 1-5 grams of reed rhizome, 1-5 grams of Solomon's seal rhizome, and 2-6 grams of lily bulb.

[0009] Furthermore, the mass ratio of kudzu root to yam is 2:2.9.

[0010] Furthermore, the mass ratio of reed rhizome, Solomon's seal rhizome, and lily bulb is 3:3.5:5.

[0011] Furthermore, a tea for those with Yin deficiency is composed of the following ingredients: 4 grams of kudzu root, 5.8 grams of yam, 3.6 grams of reed rhizome, 4.2 grams of Solomon's seal rhizome, and 6 grams of lily bulb.

[0012] The second objective of this invention is to provide an application of the above-mentioned Yin-deficient constitution tea in the preparation of products for conditioning Yin-deficient constitution.

[0013] Furthermore, the above-mentioned tea for Yin deficiency constitution is used in the preparation of drugs for high blood sugar in Yin deficiency constitution.

[0014] This invention relates to a tea for those with Yin deficiency. The preparation method is as follows: after removing impurities, washing, moistening, slicing, and drying the raw materials, the dried medicinal materials are ground into powder and passed through an 80-mesh sieve. The sieved raw materials are weighed according to the proportion, mixed evenly, and packaged into colorless and odorless food-grade nylon filter bags to obtain the tea.

[0015] Selecting fine powder with a mesh size of 80 or smaller is beneficial for improving the dissolution rate of the active ingredients in the drug, resulting in better drug efficacy.

[0016] The effects of various traditional Chinese medicine ingredients in this invention are as follows:

[0017] Kudzu root, sweet and pungent, light and dispersing, neutral with a slight cooling effect, enters the spleen and stomach meridians. It not only clears away wind-heat on the skin surface, relieves fever, and promotes the eruption of rashes, but also invigorates the spleen's clear yang to rise, generating fluids and quenching thirst, and raising yang to stop diarrhea. When used raw, it disperses and clears, generating fluids; when used in its raw form, it excels in raising but has less clearing effect. This product contains flavonoids, coumarins, puerarin, puerarin hydrosol, isoflavones, and starch, among other components.

[0018] Yam, also known as Chinese yam, is sweet and warm in nature; it enters the spleen, lung, and kidney meridians. It is known for its ability to "balance and nourish the Qi and Yin of the three jiaos," and possesses both tonifying and astringent properties. As early as the *Shennong Bencao Jing* (Shennong's Classic of Materia Medica), it was recorded that yam can "tonify the middle, benefit Qi and strength, and build muscle. Long-term consumption can sharpen hearing and vision, lighten the body, reduce hunger, and prolong life." Li Shizhen, in the *Compendium of Materia Medica*, also stated that it can "benefit kidney Qi, strengthen the spleen and stomach, stop diarrhea and dysentery, resolve phlegm, and moisturize the skin and hair." Yam is a superior tonic and has a good therapeutic effect on diabetes for the following reasons:

[0019] ①. Yam can nourish the five internal organs and is an essential medicine for treating deficiency syndromes. Diabetes is mainly caused by yin deficiency and dryness-heat, which leads to thirst. Eating yam can benefit yin, so yam can be used to treat diabetes.

[0020] ②. The glycoproteins in yam are hydrolyzed into proteins and carbohydrates in the body, which helps lower blood sugar. The amylase in yam also aids digestion and hydrolyzes starch into glucose. Therefore, it has a certain therapeutic effect on diabetes, and can also be consumed by those with weak gastrointestinal systems.

[0021] ③. Yam can replenish qi and nourish yin. It replenishes without causing stagnation and nourishes without being greasy. It replenishes the spleen qi and benefits the stomach yin. It is an essential medicine for mildly tonifying the spleen and stomach. It is suitable for long-term consumption by diabetic patients and has a significant effect on mild diabetes.

[0022] Reed rhizome, sweet and cold in nature, is light in weight and clears heat, entering the lung and stomach meridians. It clears heat from the lungs and stomach, generating fluids, relieving irritability, and stopping vomiting. It also clears heat from the skin surface, relieving rashes and toxins, and clears damp-heat, promoting urination. It combines clearing and dispersing properties, with clearing as the primary function and dispersing as a secondary function, resulting in a mild medicinal effect. It is not greasy, does not astringe, and does not harm the stomach; it is sweet and not bitter, making it easy to take. Reed rhizome mainly contains phenolic acids: caffeic acid and gentianic acid; vitamins: vitamins B1, B, and C, etc. It also contains aspartic acid, protein, fat, polysaccharides, etc.

[0023] Polygonatum odoratum, sweet and slightly cold in nature, is a mild and nourishing herb, with a balanced and unbiased character. Entering the lung meridian, it nourishes lung yin and relieves cough; entering the stomach meridian, it nourishes stomach yin and generates fluids to quench thirst. Polygonatum odoratum is nourishing without being greasy, neither cold nor hot, thus it benefits the five internal organs, nourishes qi and blood, and has a mild and moistening effect, while also clearing wind-heat. It is sweet, oily, and edible, excelling at nourishing yin and primarily acting on the spleen and stomach; therefore, long-term use does not harm the spleen and stomach. The polysaccharides, vitamin A, and niacin in Polygonatum odoratum can enhance the body's disease resistance and delay aging. The methanol extract of Polygonatum odoratum significantly reduced blood glucose levels in mice with adrenaline-induced hyperglycemia and showed a tendency to improve glucose tolerance. There are also reports that oral administration of Polygonatum odoratum to rats inhibited the increase in blood glucose induced by glucose and alloxan.

[0024] Lily bulbs, sweet in taste and cold in nature, enter the heart and lung meridians. They nourish yin and moisten the lungs; clear the heart and calm the mind. They are primarily used for chronic cough due to yin deficiency; insomnia with excessive dreaming; and mental confusion. They possess antitussive and expectorant properties, sedative effects, yin-nourishing and lung-moistening effects, strengthening effects, and anti-cancer properties. Their bulbs are rich in starch and are a valuable food, also used medicinally. They have lung-moistening and cough-relieving effects, clear heat, calm the mind, and promote urination. They also have good therapeutic effects on various cancers. Their efficacy is recorded in herbal works such as *Rihuazi Materia Medica* and *Compendium of Materia Medica Supplement*.

[0025] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0026] The raw materials of this invention are all authentic medicinal herbs listed in the "List of Items That Are Both Food and Medicine". It is designed for people with Yin deficiency, has no toxic side effects, can be consumed for a long time, and has the effects of nourishing Yin and clearing heat, nourishing Yin and moisturizing dryness, strengthening the spleen and replenishing Qi, and promoting body fluid and quenching thirst. It has a good effect on conditioning the constitution of people with Yin deficiency, and also has a good auxiliary effect on controlling fasting blood sugar levels in people with Yin deficiency and high blood sugar.

[0027] This invention selects kudzu root, which enters the spleen and stomach meridians, to both clear heat from the skin surface and invigorate the spleen and stomach's clear yang energy to generate fluids and quench thirst. Kudzu root is the chief ingredient. Chinese yam is the assistant ingredient, known for its ability to "balance and nourish the qi and yin of the three jiaos," tonifying lung qi, spleen and stomach, and kidney essence. Combined with kudzu root, it not only helps the spleen and stomach's clear yang energy to rise but also nourishes kidney yin, compensating for kudzu root's insufficient effect on the lower jiao. Reed rhizome enters the lung and stomach meridians, clearing heat from the lungs and stomach to generate fluids and relieve irritability, while also clearing heat from the skin surface and eliminating damp heat; its medicinal power is mild. Polygonatum odoratum enters the lung and stomach meridians, moistening the lungs and nourishing stomach yin. Lily bulb enters the heart and lung meridians, nourishing yin and moistening the lungs, calming the mind and spirit. These three ingredients act as adjuvants, simultaneously clearing heat from the heart, lungs, and stomach, and simultaneously moistening the lungs and nourishing stomach yin, enhancing the efficacy of the kudzu root and Chinese yam combination to nourish the yin fluids of the five internal organs and clear deficiency heat from the five internal organs.

[0028] This invention mixes kudzu root and yam, reed rhizome, Solomon's seal rhizome and lily bulb in specific proportions, which can enhance the synergistic effect of each component, resulting in better conditioning effect for people with yin deficiency constitution, and also has a better auxiliary control effect on fasting blood glucose level for people with yin deficiency constitution accompanied by hyperglycemia.

[0029] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below. Detailed Implementation

[0030] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0052] Experimental Example 1:

[0053] Three hundred and sixty adult volunteers, identified by Traditional Chinese Medicine as having Yin deficiency constitution, were selected and divided into ten groups, A1-A10, ensuring minimal average age difference and equal gender distribution among the groups. All volunteers maintained normal and consistent sleep and diet habits before and during the experiment.

[0054] The main characteristics of Yin deficiency constitution include slightly dry nose, dry mouth and throat, hot palms and soles, dry eyes, red tongue with little saliva and coating, and tinnitus. These characteristics do not affect a person's normal life and work.

[0055] Groups A1-A7 drank one packet of the tea made from the ingredients in Examples 1-7 daily, brewed with 250ml of boiling water, and continued to drink until the above-mentioned symptoms were completely cured.

[0056] Groups A8-A10 were instructed to drink one packet of tea made from the ingredients in proportions 1-3 daily, brewed with 250ml of boiling water, and continue drinking until the above symptoms were completely cured.

[0057] During the trial, no volunteers in any group took any other tea substitutes or medications.

[0058] The average time taken for each group of volunteers to achieve complete improvement in the above characteristics was recorded, and the results are shown in Table 1 below.

[0059] Table 1 Comparison of the curative effects of each embodiment and comparative example on Yin deficiency constitution

[0060]

[0061]

[0062] The results in Table 1 show that:

[0063] 1. The average time for volunteers in each embodiment group to be completely cured of the aforementioned characteristics was within 38 days, indicating that the tea brewed in this invention can effectively alleviate symptoms such as slightly dry nose, dry mouth and throat, hot palms and soles, dry eyes, red tongue with little saliva and coating, and tinnitus in people with Yin deficiency constitution. It has a good effect on the constitution and conditioning of people with Yin deficiency constitution.

[0064] 2. Among all groups, the shortest average time for complete cure of the aforementioned characteristics was 25.1 days for group A2 volunteers and 27.5 days for group A4, demonstrating a significantly better effect on regulating Yin deficiency constitution compared to other groups. The cure time for each comparative group was greater than 42 days, indicating a worse effect than the individual implementation examples. This suggests that the ratio of kudzu root to yam, and the proportions of reed rhizome, Solomon's seal rhizome, and lily bulb have a significant impact on the conditioning effect on Yin deficiency constitution. The best conditioning effect on Yin deficiency constitution was achieved when the mass ratio of kudzu root to yam was 2:2.9, and the mass ratio of reed rhizome, Solomon's seal rhizome, and lily bulb was 3:3.5:5.

[0065] 3. The average time for complete cure of the aforementioned characteristics in group A4 volunteers was 27.5 days, slightly longer than that in group A2, while all other groups took more than 30 days. This indicates that the tea brewed in Example 2 has a slightly better effect and conditioning effect on the constitution of people with Yin deficiency than the tea brewed in Example 4, and is even better than the tea brewed in other groups.

[0066] Experimental Example 2:

[0067] Twenty-seventy volunteers, diagnosed with Yin deficiency and hyperglycemia by Traditional Chinese Medicine, were selected and randomly divided into 10 groups. All volunteers had fasting blood glucose levels between 6.1 and 10 mmol / L within the past month. The groups had minimal age differences and equal gender distribution. All volunteers maintained normal and consistent sleep and dietary habits before and during the trial.

[0068] Experimental groups 1-7 drank one tea bag made from the ingredients in Examples 1-7 daily, brewed with 250ml of boiling water, for one month. They did not take any other tea substitutes or medications.

[0069] Experimental groups 8-10 drank one tea bag made from the ingredients in proportions 1-3 daily, brewed with 250ml of boiling water, for one month. They did not take any other tea substitutes or medications.

[0070] During the trial, volunteers had their fasting blood glucose tested once a day before the trial began, once a day during the first week, once every two days during the second week, once every two days during the third week, once every two days during the fourth week, and once on the second day after the trial ended. The average results for each group are shown in Table 2.

[0071] Table 2. Average fasting blood glucose levels for each group (unit: mmol / L)

[0072]

[0073]

[0074] The results in Table 2 show that:

[0075] The average fasting blood glucose levels of volunteers in all groups decreased, and by the fourth week, they had basically returned to near normal levels. By the end of the experiment, they remained within the normal range. The average decrease in each group before and after the experiment was more than 2 mmol / L. Among them, the average decrease in each example group was more than 2.5 mmol / L, the average decrease in the comparative example group was less than 2.3 mmol / L, and the decrease in experimental group 2 was 2.91 mmol / L, which was the largest decrease among the 10 experimental groups.

[0076] It is evident that the brewed teas of the various embodiments of this invention can lower fasting blood glucose levels in individuals with Yin deficiency and hyperglycemia. The brewed tea of ​​Embodiment 2 showed the best effect in lowering fasting blood glucose levels in these individuals. The best results were achieved when the mass ratio of kudzu root to yam was 2:2.9, and the mass ratio of reed rhizome, Solomon's seal rhizome, and lily bulb was 3:3.5:5. Even when the mass ratio of kudzu root to yam was 2:2.4–3.0, and the mass ratio of reed rhizome, Solomon's seal rhizome, and lily bulb was 3:3.3–3.7:4.5–5.5, there were still relatively good effects in lowering fasting blood glucose levels in these individuals. The effects of each embodiment in lowering fasting blood glucose levels in individuals with Yin deficiency and hyperglycemia were significantly better than those of the other embodiments. Comparative Examples 1 and 2 also showed some effect in lowering fasting blood glucose levels in individuals with Yin deficiency and hyperglycemia, but the effect was slow and poor. Comparative Example 3 showed poor results in lowering fasting blood glucose levels in individuals with Yin deficiency and hyperglycemia.

[0077] The sequence numbers of the above embodiments of the present invention are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments.

[0078] The above description is based on specific embodiments, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these are within the protection scope of the present invention.
