Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicinal tea substitutes, and in particular to three-flower tea and a preparation method and application thereof. Background Art

[0002] Depression is a disease in traditional Chinese medicine, which is mainly caused by emotional discomfort and stagnation of qi. Clinical manifestations include depression, restlessness, chest fullness, chest and flank pain, irritability and crying, or foreign body obstruction in the throat. Its causes involve liver failure to release, spleen failure to function properly, heart failure to nourish, and imbalance of yin and yang, qi and blood in the internal organs. The disease is mainly located in the liver, but it may also involve internal organs such as the heart, spleen, and kidney. At the beginning of depression, the lesions are mainly qi stagnation, often accompanied by blood stasis, fire transformation, phlegm accumulation, food stagnation and other symptoms. However, as the disease progresses, depression may turn from real to virtual, forming deficiency lesions of internal organs such as the heart, spleen, liver, and kidney. TCM treatment methods include syndrome differentiation and treatment, Chinese medicine conditioning, and special mood regulation. When treating depression with Chinese medicine, syndrome differentiation and treatment will be carried out according to the patient's specific symptoms.

[0003] For example, the liver qi stagnation type: it is often manifested as depression, sighing, and sometimes accompanied by pain in the ribs. During treatment, Chaihu Shugan San is often used to relieve liver qi and relieve depression. Qi stagnation and fire type: patients are impatient and irritable, and may also feel chest tightness, pain in the ribs, dry and bitter mouth, etc. During treatment, Danzhi Xiaoyao San or Longdan Xiegan Tang are often used to clear liver and purge fire, relieve depression and relieve liver. Qi stagnation and phlegm obstruction type: it is manifested as if there is a foreign body blocking the throat, which cannot be coughed out or swallowed, and chest tightness. During treatment, Banxia Houpu Tang is often used to resolve phlegm, promote qi and relieve depression. For the heart and spleen deficiency type, Guipi Tang is often used to strengthen the spleen and nourish the heart, replenish qi and blood; for the liver and kidney deficiency type, Erxian Tang is often used to balance and nourish the liver and kidney and harmonize yin and yang.

[0004] However, it should be noted that Chinese medicine treatment needs to comprehensively consider the patient's constitution, condition and other factors. Therefore, the specific medication and dosage should be determined by the doctor according to the patient's specific situation. At the same time, when taking Chinese medicine, patients should also follow the doctor's instructions and pay attention to the method and precautions of taking the medicine. Taking into account the work pace and life pressure of modern people, the high incidence of emotional distress, combined with the actual compliance of taking Chinese medicine. Further exploration based on syndrome differentiation and treatment, digging out suitable medicine and food homology, comfortable medicinal taste substitutes, clarifying their preparation process, more convenient for contemporary people's taking habits, and effectively improving medication compliance is of great significance. Summary of the invention

[0005] The present invention aims to provide a three-flower tea and a preparation method and application thereof, aiming to achieve the effect of soothing the liver and relieving qi by using a tea substitute that is both medicinal and edible, while improving medication compliance.

[0006] To achieve the above purpose, the present invention adopts the following technical scheme: a three-flower tea, which includes the following raw materials, by weight, 10 to 20 parts of mint, 10 to 20 parts of roses, 5 to 15 parts of chrysanthemums, and 10 to 20 parts of chrysanthemums.

[0007] Preferably, as an improvement, the mass parts of each raw material are: 10-15 parts of mint, 10-15 parts of roses, 10-15 parts of chrysanthemums, and 10-15 parts of chrysanthemums.

[0008] Preferably, as an improvement, the mass parts of each raw material are: 10 parts of mint, 10 parts of rose, 5 parts of chrysanthemum, and 10 parts of chrysanthemum.

[0009] Preferably, as an improvement, the mass parts of each raw material are: 20 parts of mint, 20 parts of rose, 15 parts of chrysanthemum, and 10 parts of chrysanthemum.

[0010] Preferably, as an improvement, a method for preparing three-flower tea comprises the following steps:

[0011] Step 1: Material selection: Choose authentic medicinal materials such as mint, rose, chrysanthemum, and chrysanthemum;

[0012] Step 2: Cleaning and drying: Wash with water and then dry;

[0013] Step 3: Mix and grind: Mix and grind according to the proportion to get Sanhua Tea.

[0014] Preferably, as an improvement, in step 2, the drying temperature is 30-45° C., and the drying time is 1-2.

[0015] Preferably, as an improvement, in step three, the particle size after grinding is 1 to 5 mm.

[0016] Preferably, as an improvement, a three-flower tea is used in the preparation of a liver-soothing and qi-regulating medicine.

[0017] The principle and advantage of this scheme are: in actual application, in this technical scheme, mint (Mentha haplocalyx) has the effect of soothing the liver and relieving depression, and can relieve the discomfort symptoms caused by liver qi stagnation. Rose (Rosa rugosa) has the effect of soothing the liver and relieving depression, and can help relieve liver qi stagnation caused by bad mood. The aromatic components in rose help relieve depression and improve mood. Chrysanthemum (Chrysanthemumindicum) has the effect of clearing heat and detoxifying, and can help relieve various symptoms caused by heat toxins. Citrus aurantium var.amara has the effect of regulating qi and widening the chest, and can help relieve symptoms such as chest tightness and chest pain caused by qi stagnation. In addition, the volatile oil components in Citrus aurantium have a certain calming effect, which can help improve sleep quality. The above-mentioned medicinal materials are combined into a Chinese medicine substitute tea, which has a significant effect of regulating qi and soothing the liver, relieving worries and relieving depression, and has a good effect on treating depression, and is low in cost and has no toxic side effects. At the same time, the preparation method adopted by the present invention can extract and utilize the effective active ingredients of each medicine to the maximum extent, maximize the efficacy of each medicine and the efficacy of health products, improve their bioavailability, and correspondingly reduce the amount of original medicinal materials.

[0018] In summary, the beneficial effects of this technical solution are:

[0019] 1. In terms of material selection, this technical solution strictly selects authentic medicinal materials, strictly controls different types of flowers, and selects appropriate temperature-controlled boxes to dry the various components in the scented tea, overcoming the technical difficulties of properties and bioavailability between different components. In the process of scented tea production, it overcomes the technical obstacles of scented tea fragrance, and uses special packaging materials to retain the aroma components in the scented tea.

[0020] 2. In this technical solution, mint and rose have obvious synergistic and strong effects. Mint is pungent, cool in nature, and enters the lung and liver meridians, and has the effect of soothing the liver and promoting qi. Rose tastes dry and slightly bitter, is warm in nature, and enters the liver and spleen meridians, and has the effect of promoting qi and relieving depression. The two are warm and cool, and they synergistically enhance the effect of promoting qi and soothing the liver.

[0021] 3. In the present technical solution, the raw material used is the uncommon hawksbill flower, which is the dried flower bud of the rutaceae plant hawksbill flower, also known as citron flower. It is sweet, slightly bitter, neutral in nature, and enters the liver and stomach meridians. It has the effects of regulating qi, widening the chest, appetizing and stopping vomiting. The dried mature fruits of rutaceae plants such as citron and bergamot are commonly used in this field. Hawksbill flower has the advantages of light weight and easy precipitation of effective ingredients. Its effect of regulating qi is not inferior to that of citron and bergamot of the same type of plants, and its volatile oil components have a certain calming effect.

[0022] 4. Compared with traditional prescriptions for soothing the liver and regulating qi, such as Xiaoyao Powder, this plan eliminates herbs such as Bupleurum and Angelica. Herbs such as Bupleurum and Angelica are bitter, so this plan eliminates bitter herbs from traditional prescriptions for soothing the liver and regulating qi, which is more conducive to the acceptance of the beneficiary groups. In addition, the herbs selected in this plan have the advantage of being aromatic. BRIEF DESCRIPTION OF THE DRAWINGS

[0107] Experimental Example 3 Animal Experiment

[0108] Experimental design: 100 SPF Wistar rats, weighing 160-200g, half male and half female, were randomly divided into 3 groups: blank group, model group, and Sanhua Jieyou tea group, with 10 rats in each group. The depression model was established by chronic psychological stress plus solitary rearing. One rat was housed in each cage and subjected to various stress stimuli, including water deprivation for 24 hours, food deprivation for 24 hours, tail clamping for 1 minute, swimming in 10℃ ice water for 5 minutes, shaking (1 time / s, lasting 5 minutes), day and night reversal, electric shock to the sole of the foot (voltage 50mV, 5s / time, interval 5s, total stimulation 10 times), one stimulus was randomly selected every day, each stimulus was used an average of 4 times, continuous stimulation every day, and the modeling time was a total of 4 weeks (28 days). After the third week of modeling, Sanhua Jieyou tea was given by gavage twice a day for 14 consecutive days. The rats were collected 2 hours after the last gavage. Rats were anesthetized with chloral hydrate, and then the spinal cord was fixed by aortic perfusion with 4% paraformaldehyde, routinely embedded in paraffin, sliced, and immunohistochemical staining for 5-HT was performed. An optical microscope (10×40 times) was used to observe the changes in the positive expression of 5-HT in the spinal cord. Using a computer image analysis system, 5 fields of view (10×40 times) were randomly selected at the same structural position of each slice, and the average IOD (cumulative optical density) value of 5-HT positive expression in the spinal cord of the random field of view was calculated, which represents the amount of 5-HT content. The larger the IOD value, the more 5-HT content. The results are shown in Table 5 below: The results show that compared with the blank group, the 5-HT level in the spinal cord of the model group increased significantly, indicating that the model was successfully established. The 5-HT level in the spinal cord of the Sanhua Jieyou Tea group was significantly lower than that of the model group, indicating that the Sanhua Jieyou Tea group has a certain effect on reducing the 5-HT level in the spinal cord of depressed animals and can improve the depressive symptoms of depressed animals.
