Animal experiments

1. Animal grouping: the 40 experimental rats were randomly divided into 4 groups: blank control group, model control group, treatment group 1, treatment group 2, 10 each.

2. Establishing a model: preparing parachlorophenylalanine (PCPA) into suspension with the concentration of 30mg/mL by using weak alkaline physiological saline with the pH value of 7-8, respectively injecting 1mL/100g of PCPA suspension into the abdominal cavity of a model control group and a treatment group once a day for 2 days continuously; injecting the same volume of alkalescent normal saline into the abdominal cavity of a blank control group; after the first intraperitoneal injection is carried out for 28-30h, the circadian rhythm of the rat disappears, the activity is increased, the rat is difficult to fall asleep and is easy to be awakened by environmental interference, the overall observation is obviously different from that of a blank control group, and the model establishment is successful.

3. The test method comprises the following steps: the substitute tea prepared in example 2 and comparative example 2 was respectively brewed into 300mL solution for gastric perfusion. After the model is established, the rats in the treatment group are administrated by intragastric administration according to 1ml/100g, the tea is replaced in the intragastric administration example 2 in the treatment group 1, the tea is replaced in the intragastric administration comparative example 2 in the treatment group 2, 1 time per day, and the administration is continuously carried out for 8 days. The autonomic activity of the rats was measured 30 minutes before and after the administration on day 1 and day 7, respectively, and after the rats were placed in an autonomic activity apparatus to adapt for 2min, the autonomic activity frequency of the rats for 5min and the average value of each group were recorded. Pentobarbital sodium 30mg/kg is intraperitoneally injected 30min after the last administration, and the sleep latency (from pentobarbital sodium injection to disappearance of righting reflex) and the sleep time (from disappearance of righting reflex to restoration to normal) of each group of rats are observed and recorded.

4. As a result: compared with a blank control group, the PCPA induced rat insomnia model can increase rat autonomous activity, prolong sleep latency and shorten sleep time. Whereas the number of voluntary activities in the rats of treatment group 1 was significantly reduced after 7 days of administration. The sleep latency of treatment group 1 was significantly lower than that of the model control group and the blank control group, while the duration of sleep was the longest and significantly different from that of the model control group and the blank control group. Treatment group 1 had lower numbers of autonomic activity than treatment group 2 and had less sleep latency than treatment group 2 and longer sleep time than treatment group 2 after day 7 dosing. The results are shown in Table 1.

TABLE 1 autonomous Activity times, sleep latency and sleep time of rats in each group

Clinical observations

1. Clinical cases: the patients who have insomnia for more than one week are selected and randomly divided into 8 groups; the number of effective cases is 735, including 123 patients 15-24 years old, 382 patients 25-40 years old, 170 patients 41-60 years old, and 60 patients over 60 years old.

2. The treatment method comprises the following steps: the group A to the group D take the substitutional tea of the embodiment 1-4 of the invention respectively, the group E to the group I take the substitutional tea of the comparative example 1-4 respectively, each bag is brewed with about 300mL of boiled water for 3-5 minutes and can be drunk, each bag can be brewed for 3-4 times repeatedly, one bag is taken every day, and the tea is taken for 6 weeks continuously.

3. The therapeutic effect judgment standard is as follows: efficacy was assessed as Pittsburgh Sleep Quality Index (PSQI) and assessed before, 2 weeks, 4 weeks and 6 weeks of treatment, respectively. PSQI reduction rate was used as therapeutic efficacy criterion: and (3) healing: the PSQI reduction rate is more than 80%; the effect is shown: the PSQI reduction rate is 60-80%; the method has the following advantages: the PSQI reduction rate is 30-60%; and (4) invalidation: the PSQI reduction fraction is less than 30%.

4. Therapeutic effects

The PSQI comprehensive score results of each group showed that the PSQI score was significantly lower than that before treatment after 4 weeks of administration of the tea substitute of the present invention, and the total effective rate of examples 1 to 4 reached 80% or more after 6 weeks of administration (table 3). The effective rate of the comparative examples 1 to 3 is lower than that of the examples, because one or two traditional Chinese medicines are saved in the raw materials, the synergistic effect of the formula is weakened. And comparative example 4 is obtained by directly drying without water boiling and adsorption processes, so that the dissolution rate of the main components of the lily, the spina date seed and the tuckahoe is reduced, and the treatment effect is influenced. After the insomnia patients who participate in clinical observation are treated for 6 weeks, more than 7 patients gradually try to reduce the use amount while improving the sleep, and finally stop using the medicine, so that the insomnia symptoms do not rebound, which indicates that the product does not generate dependence and tolerance.
