Technical Field

The invention relates to health-care tea, in particular to spleen-tonifying and dehumidifying tea and a preparation method thereof.

Background

Dampness refers to the phenomenon of spleen-dampness retention caused by the hypofunction of the spleen or the heavy diet. The moisture is divided into external moisture and internal moisture according to the source, the external moisture refers to air moisture and environmental moisture, such as rainy season in summer or bad living habits (air conditioning, wet hair falling asleep) and the like, and the external moisture can invade into the human body to cause diseases; internal dampness refers to the failure of the digestive system to operate, i.e., the water flow in the body is out of control, which leads to the accumulation of body fluids, or the formation of internal dampness due to excessive water in the diet, alcohol consumption, cold diet, etc.

Modern life style causes more or less moisture in human body, and the most common way of eliminating dampness is to drink the health-care tea for eliminating dampness. The existing health tea is mainly prepared by using red beans and pearl barley as main raw materials and through the modes of baking, frying, rolling, grinding and the like; the health tea is brewed with water and drunk as tea soup, thereby achieving the efficacy of eliminating dampness and promoting health. However, because some effective components in the raw materials such as the red beans and the coix seeds can be dissolved out only by long-time decoction and are difficult to dissolve out only by brewing, the effective components in the raw materials such as the red beans and the coix seeds cannot be well utilized by the existing health-care tea, and the dampness eliminating effect is relatively poor.

					First group	49	1	0	100
Second group	39	5	6	88
					Third group	45	1	4	92

As can be seen from Table 2, the curative effect of the spleen-invigorating and dehumidifying tea prepared by the preparation method of the invention is obviously superior to that of the comparative example, which shows that the preparation method of the invention can furthest retain the effective components of the traditional Chinese medicines and is more beneficial to exerting the curative effect of spleen-invigorating and dehumidifying.

Clinical cases during the drinking trial:

in case 1, certain Liu, female, age 45, greasy tongue coating, sticky mouth with halitosis, drowsiness, hypodynamia, dreaminess, body weight and body fat, the spleen-invigorating and dehumidifying tea N1 prepared in example 1 is eaten for 9 weeks, clinical symptoms are basically cured, and the body constitution is basically recovered.

In case 2, a certain queen, male, a person of 52 years old, white and greasy tongue coating, sticky and greasy mouth and mouth smell, tiredness and hypodynamia, fatness and fat abdomen, the phlegm-dampness constitution is distinguished by the traditional Chinese medicine, after eating the spleen-tonifying and dehumidifying N1 of example 1 for 11 weeks, the clinical symptoms are basically cured, and the constitution is basically recovered to be normal.

In case 3, Zhangzhi, male, 49 years old, white and greasy tongue coating, excessive phlegm, stuffy feeling in chest and epigastrium, excessive and sticky sweat, heavy body, easy sleepiness, lethargy and unsmooth stool, the traditional Chinese medicine dialectical phlegm-dampness constitution belongs to phlegm-dampness constitution, and after eating the spleen-tonifying and dehumidifying tea N1 of example 1 for 10 weeks, the clinical symptoms are basically cured, and the constitution is basically recovered to be normal.

In case 4, a certain populus is in the age of 53, the tongue is greasy, the mouth is sticky, the appetite is poor, the body is tired and hypodynamia is caused, the phlegm-damp physique is dialectical in the traditional Chinese medicine, after eating the spleen-tonifying and dehumidifying tea N1 in example 1 for 10 weeks, the clinical symptoms are basically cured, and the physique is basically recovered to be normal.

13) Evaluation experiment

80 common consumers are recruited to conduct sensory evaluation on the spleen tonifying and dehumidifying tea N1-N6 and D1-D2 in an anonymous scoring mode, wherein 4 indexes of color, smell, taste and overall preference are evaluated respectively, the lowest score is 1, the full score is 10, and the higher the score is, the better the effect is. After tasting is finished, the sensory evaluation results of 80 common consumers are subjected to statistical analysis, and the average results are shown in the following table:

TABLE 3 summary of sensory evaluation results

Spleen-tonifying and dehumidifying tea	Color	Smell(s)	Taste of the product	Overall preference
					N1	9.1	9.2	9.0	9.1
N2	9.0	9.0	8.7	8.9
					N3	8.9	9.1	8.5	8.8
N4	8.6	8.7	8.8	8.7
					N5	8.7	8.5	8.6	8.6
N6	8.6	8.7	8.9	8.7
					D1	8.1	7.7	8.2	7.9
D2	7.7	6.6	4.1	4.7

As can be seen from Table 3, the spleen-invigorating and dehumidifying tea prepared by the invention has good color, smell and taste, and high overall preference; the spleen-tonifying and dehumidifying tea D2 has poor taste and obviously low overall preference because barley residue and gardenia residue are not removed in the preparation process; although the spleen-invigorating and dehumidifying tea D1 scores relatively well in all aspects, the spleen-invigorating and dehumidifying tea still does not score as high as the color, smell, taste and overall preference of the invention, and the efficacy is relatively poor as seen in the above experiments. Therefore, the spleen-invigorating and dehumidifying tea prepared by the preparation method disclosed by the invention is high in sensory evaluation and good in curative effect.
