Description

Pharmaceutical composition for improving sleep quality
Technical Field
The invention belongs to the field of pharmacy, and relates to a pharmaceutical composition for improving sleep quality.
Background
Insomnia is a common sleep disorder in modern society, and generally refers to a subjective experience that a patient does not meet sleep time or quality and affects social functions in the daytime, and the physical and mental health of people is seriously affected. Clinically, the symptoms of difficult falling asleep, easy waking after sleeping, no longer sleeping after waking up, waking up during sleep and no sleeping all over night are characterized by the difficulty falling asleep, and the symptoms of absentmindedness, slow response, tiredness, hypodynamia, chagrin and the like in the daytime are often accompanied. With the rapid development of economy in China, the pace of life is continuously accelerated, the pressure of life and the working pressure of people are increased sharply, so that the incidence rate of epidemic diseases related to sleep disorder is increased day by day, and the Chinese sleep quality report in 2018 indicates that 83.81% of visitors in China have sleep troubles, wherein the difficulty in falling asleep accounts for 25.83%, and the light sleep accounts for 26.49%. According to the survey of the world health organization, about 27 percent of people all over the world have sleep disorder, the incidence rate of insomnia of adults in China is as high as 38.2 percent, and the sleep disorder becomes an important health problem of global concern.
Modern medicine considers that sleep disorder is often related to neurotransmitters, immunoregulation, intestinal flora, environmental and psychological factors, and the like, and a treatment mode mainly based on drug treatment and assisted by psychological behavior intervention is usually adopted clinically. The continuous sleep disorder can cause various related diseases such as human body chronic fatigue, hypomnesis, low immunity, cardiovascular damage, metabolic disturbance and the like, and even lead to suicide in severe cases. Therefore, improving sleep plays a key role in conditioning sub-health of human bodies, reducing occurrence of related epidemic diseases and improving life quality of people. At present, the clinical chemical drugs for treating sleep disorder mainly comprise barbiturates, benzodiazepines, non-benzodiazepines and the like, the drugs have quick response and definite action mechanism, but the drugs are easy to generate side effects such as residual effect, amnesia effect, drug withdrawal effect and the like after long-term administration.
Insomnia is also recorded in traditional Chinese medicine, and there are related records of sleeping disorders such as "contemplational for the eye", "insomnia", "decubitus", and the like in the yellow emperor's internal classic. In the traditional Chinese medicine practice, natural medicinal materials are usually used or are prepared with daily food in a compound way to improve sleep, so that the traditional Chinese medicine has the advantage of being difficult to generate drug resistance and dependence, is a sustainable slow conditioning mode, and finally enables people to sleep normally.
Along with the increase of insomnia rate, the demand of health care products for improving sleep is continuously increased. Meanwhile, in recent years, the development of the health industry is also very important in China, and the development of the sleep improvement health product industry is promoted to a certain extent by the coming of a plurality of related policies of the health product industry and the health industry. In 7 months 2019, 15 major special actions are proposed to be developed around the centers of disease prevention and health in "health Chinese actions (2019-2030)", so as to promote the conversion from treating diseases to human health, and try to prevent the people from getting ill or getting ill less; the goals related to sleep are: the prevalence rate of insomnia patients is gradually reduced, and the daily average sleeping time of adults is increased to 7-8 hours, and the like. According to data, the market scale of the Chinese sleep improvement health care product industry in 2018 is 128 hundred million yuan, and the market scale is increased by 3.1% in year. Therefore, the health care product for improving sleep has a huge market in China, and the current product can not meet the requirement.
At present, 635 sleep improvement health-care foods are inquired by a special food supervision department website of the State market supervision and administration, wherein most of the imported sleep improvement health-care foods are prepared by taking melatonin as a raw material, and nearly 1/5 of the domestic health-care foods are also prepared by taking the melatonin as the raw material. Melatonin is also called Melatonin, and pineal hormone (Melatonin, MT is commonly called Melatonin) is a bioactive factor secreted by the pineal body of the brain. It has been reported that long-term administration of melatonin-containing nutraceuticals may affect gonadal development in children. Experts point out that the elderly are also cautious to take melatonin. If insomnia in the elderly is not associated with insufficient melatonin secretion, blindly taking such products is not only ineffective, but may even be harmful. Because long-term melatonin supplementation can inhibit normal melatonin secretion to cause pineal atrophy. Researchers at the diabetes center at the university of londer, sweden, found that increased melatonin signaling in islet cells decreased insulin secretion, possibly leading to hyperglycemia and increased risk of type 2 diabetes.
Traditional Chinese medicine considers that the cause of sleep disorder is caused by emotional, dietary or internal injury such as deficiency of qi and blood, and the sleep disorder is easy to cause disharmony of qi and blood and imbalance of yin and yang of heart, liver, gallbladder, spleen, stomach, kidney and the like. Ling Shu & kou Wen (Ling Shu & kou Wen) mentions that "Yang Qi is exhausted, yin Qi is preponderant, and contemplational for contemplational moment; the treatment of deficiency of yin qi and preponderance of yang qi is good. Elucidating the relationship between yin-yang qi and yin-qi of the human body. Lingshu-evil-Gu (Lingshu-Xie-Gu) says that the wei-defensive qi can move outside only when it is in the five zang-organs and six fu-organs, while yang can not enter yin when it is in yang, yang qi can be preponderant when it is in yang, yang qi can collapse when it is in yang, and yin deficiency can not be used for contemplational women. Su Wen & Sheng Qi Tong Tian Lun also points out "Yin Ping Yang secret, shen Zhi, yin Yang separation and Jing Qi Zhi Ke". Therefore, imbalance of yin and yang, disharmony of ying and wei and visceral disorder are the main pathogenesis of insomnia, the etiology includes external pathogen attack, seven-emotion internal injury, improper diet, congenital deficiency, old age and asthenia, etc., and the disease is localized in the heart and relates to the liver, spleen and kidney. The traditional Chinese medicine also thinks that insomnia mostly belongs to deficiency of yin and blood of liver and kidney, and is often caused by liver depression and qi stagnation, deficiency yang and stagnated fire disturbing heart spirit. The book of "Puji Benshi Fang" (prescription of general relief): "pacify the liver without being attacked by pathogen, so lying down would cause the spirit to fall to the liver and calm the mind to cause sleep. Liver has pathogenic factors, and spirit can not return, but spirit can be raised when lying down and separated when lying down. The "blood syndrome treatise" is characterized by: yang floating outside, failing to enter the liver, insomnia. The facial Qian Ling is considered that the liver depression is most apt to cause fire for a long time, the liver fire is reversed to rush the liver spirit, the spirit shakes to make sleep restless, the syndrome is manifested as restlessness at night, difficulty in falling asleep, irritability and the like. Wangping considers that insomnia is caused by liver depression as the first disease, liver qi stagnation is formed by liver loss and catharsis, which disturbs the mind, and insomnia is caused by hidden spirit. Cuochulins thinks that the stagnation of the liver-qi transforms into fire, consumes blood and injures yin, causes imbalance of yin and yang, finally damages liver and kidney, disturbs heart spirit and leads to insomnia. "Jingyue full book, insomnia" cloud: its general indications include deficiency of essence and blood, disharmony between yin and yang, and insecurity of the ears. Su Wen, chapter VI Tibetan elephant treaty, cloud: the kidney governs hibernation, seals the root and stores essence. Book of Ling Shu & Ben Shen cloud: "liver stores blood and blood is rounded off. The theory of "the theory of redundancy of yang and deficiency of yin" is recorded: the kidney is the dominant one in occlusion and the liver is the dominant one in excretion. Both of them are involved in fire, which is attributed to the heart.
The traditional Chinese medicine can improve sleep disorder, follow the traditional Chinese medicine syndrome differentiation theory, and restore the normal state of the organism by regulating qi, blood and yin and yang of viscera. Roc thinks that insomnia and anxiety cause the conflagration along with external objective stimulation on the one hand and various fire-heat symptoms appear; on the other hand, fire-heat consuming essence and blood causes hyperactivity of yang and deficiency of yin, the fire-heat condition is manifested in the exterior, while deficiency of yin and essence and blood changes in the interior. The pathogenesis of insomnia and anxiety is fire heat, the pathology is ministerial fire, and the treatment should clear heat and purge fire, and take the qi and yin deficiency into consideration. The Liwenlong considers that the kidney stores essence and is the water organ; the heart governs mind, and pertains to yang, when kidney water is deficient, it cannot go up to heart, water and fire are not in harmony, and heart fire is hyperactivity, resulting in insomnia and anxiety, the key points of treatment are nourishing kidney yin, lowering heart fire, and nourishing heart spirit.
Therefore, the formula of the sleep-improving health-care product is developed from the traditional Chinese medicine theory, and a safe health-care food with the sleep-improving function is developed. The health product with the function of improving sleep is prepared by taking spina date seeds, cistanche, poria cocos, rhizoma anemarrhenae, roses, platycladi seeds and lily as raw materials. The spina date seed is sweet and sour in taste and neutral in nature, enters liver, gallbladder and heart channels, and has the effects of nourishing the heart, tonifying the liver, calming the heart, soothing the nerves, arresting sweating and promoting the secretion of saliva or body fluid. Cistanchis herba is sweet, salty, warm in nature, and enters kidney and large intestine channels, and has effects of invigorating kidney yang, replenishing essence and blood, loosening bowel to relieve constipation. Poria has sweet and light taste, neutral nature, and effects of benefiting heart, lung, spleen, and kidney channels, promoting diuresis, eliminating dampness, invigorating spleen, and calming heart. Rhizoma anemarrhenae is bitter and sweet in taste and cold in nature, enters lung, stomach and kidney channels, and has the effects of clearing heat and purging fire, and nourishing yin and moistening dryness. The rose flower is sweet in taste, slightly bitter in taste and warm in nature, enters liver and spleen channels, and has the effects of promoting qi circulation, relieving depression, regulating blood and relieving pain. The arborvitae seed is sweet in taste and neutral in nature, enters heart, kidney and large intestine channels, and has the effects of nourishing heart, soothing nerves, moistening intestines, relaxing bowels and arresting sweating. Lily has sweet taste and cold nature, and has the effects of nourishing yin, moistening lung, clearing away heart-fire and tranquilizing mind. In the whole formula, the spina date seed is a monarch drug, has sweet and mild nature and taste, enters heart and liver channels, and has the effects of nourishing blood, tonifying liver, calming heart and soothing nerves; poria has sweet and light flavor and mild nature, and can calm heart and tranquilize mind; rhizoma anemarrhenae is cold in nature, and has the effects of nourishing yin and clearing heat; the arborvitae seed is sweet in taste and neutral in nature, and can nourish heart and calm mind; the lily is sweet in taste and cold in nature, and has the effects of nourishing yin, moistening lung, clearing away heart-fire and tranquilizing; the four medicines are used as ministerial medicines; cistanche deserticola is sweet and salty in taste and warm in nature, can tonify kidney yang, benefit essence and blood, assists in treating cold nature such as rhizoma anemarrhenae, lily and the like, and prevents excessive clearing of heat and clearing away heart-fire; rose is sweet and slightly bitter in taste, warm in nature, and has the effects of promoting qi circulation, resolving stagnation, regulating blood, and regulating yin and yang.
