What are common health food ingredients that help improve sleep?

According to the relevant regulations, Chinese medicines such as tianma, schizandra, acanthopanax, cypress, pearl and shouwu-teng can be used in health food. Studies have shown that all of the above drugs have a certain sedative-hypnotic effect.
Tianma
Tianma contains asparagus, asparagus glycosides, vanillin, vanillinol, sesquiterpenes, purines and other components, of which asparagus is its main active ingredient. Studies have shown that mice given intraperitoneal injection of asparagine or gavage given ultra-micro asparagine powder have the effect of improving sleep.
Schisandra
Schisandra contains lignans, polysaccharides, volatile oils, organic acids and other components. Literature reports that the freeze-dried powder of Schisandra chinensis can improve the sleep of Drosophila melanogaster with certain quantitative and temporal relationship characteristics; the decoction of Schisandra chinensis can prolong the total sleep time and the duration of stage II slow-wave sleep in rats. The study showed that lignans are the active components of the hypnotic effect of Schisandra chinensis.
Acanthopanax
The main components of Acanthopanax are glycosides, polysaccharides and flavonoids, as well as coumarins, fatty acids, volatile oils, amino acids and trace elements. Literature reports that the aqueous extract of Sophora japonica root and Sophora japonica saponin have the effect of improving sleep in rats.
Cedar Kernel
Cedar seed kernel contains cypress saponin, volatile oil and other components, the seeds contain cypress alcohol, sterol and diterpenoid components. Studies have shown that cypress kernel saponin, cypress kernel oil on experimental animals have sedative hypnotic effect.
Pearl
Pearl contains a variety of amino acids, trace elements, taurine, small molecule active peptides and porphyrin-like components. Literature reports that ultra-fine pearl powder has the effect of improving sleep in mice.
Shouwu Teng
Studies have shown that the main extracts of the first Wu Wu vine, nightshade glycoside, nightshade anthraquinone and nightshade flavonoids have the effect of improving sleep, of which nightshade glycoside is more significant.
Mullein
The wood squid contains flavonoids, volatile oils, phenolic acids and other components. Literature reports that the alcoholic extracts of Cnidium monnieri have obvious sedative-hypnotic effect on mice.
Polygala
The main components of farzhi for saponins, has been isolated more than 80 kinds of saponins. Research shows that Yuanzhi saponins have obvious sedative-hypnotic effect, and its tranquilizing effect has not been affected after honey-roasting under different conditions.
Eucommia
Cortex Eucommia contains Cortex Eucommia gum, Cortex Eucommia glycosides, Cortex Eucommia alcohol, phenols, organic acids, flavonoids and other components. Literature reports that ethyl acetate, water-saturated n-butanol, and water-soluble parts of Cortex Eucommia Ulmoides have the effect of improving sleep in mice, and the ethyl acetate part is stronger.
Salvia miltiorrhiza
The chemical composition of Salvia divinorum can be divided into two major parts, fat-soluble and water-soluble, the former being tanshinones, such as tanshinone I, tanshinone IIα, tanshinone IIβ; the latter mainly being phenolic acids, such as tanshin, protocatechuic aldehyde. Studies have shown that the aqueous extract of Salvia miltiorrhiza has obvious sedative-hypnotic effect.
Astragalus
Astragalus mainly contains saponins and flavonoids, such as astragaloside, soybean saponin, various glucosides, spiny aristolochicin, and trichostatin isoflavones. Literature reports that the aqueous extract of Astragalus has some sedative-hypnotic effect on mice.
Radix Rehmanniae Praeparata
Radix Rehmanniae Praeparata contains a small amount of cyclic allyl ether terpenes such as (motherwort glycosides, peach leaf coral glycosides), and monoterpene components (such as pyroxylin A, B, C), but also contains amino acids, sugars and other components. Studies have shown that the decoction of Radix Rehmanniae Praeparata and Radix Rehmanniae Polysaccharides have obvious sedative-hypnotic effects on mice.
Centella asiatica
Centella asiatica mainly contains triterpenoid saponins (such as hydroxy Centella asiatica glycosides, Centella asiatica glycosides), polyynuclear olefins (such as C19H2803, C16H2102), volatile oils (such as stone to bamboo alkene, longifolia alkene) and other components. Literature reports that Centella asiatica glucoside has obvious sedative-hypnotic effect on mice.
Lateral cypress leaves
The leaves of Pterocarpus indicus contain volatile oils (e.g. pterocarpene, pterocarpone), flavonoids (poplar bark, quercetin) and other components. Studies have shown that the volatile components of cypress leaves have a certain sedative-hypnotic effect on humans and experimental animals.
Peony Bark
Peony bark contains peony phenol, peony phenolic glycosides, paeoniflorin and other components. Literature reports that extracts of peony bark, danpi phenol and total danpi glycosides have certain sedative-hypnotic effects.
Chasteberry
Chasteberry contains oleanolic acid, rhodioloside, flavonoids, polysaccharides, volatile oil and trace elements. Literature reports that Chasteberry has obvious sedative-hypnotic effect on mice.
Ginseng
Ginsenoside is the main active ingredient of ginseng. Studies have shown that ginseng has a bi-directional regulatory effect on central functions, which is related to the effects of different saponin components. Generally speaking, ginsenosides Rb have sedative effects, Rg have excitatory effects, and the mixture of Rb and Rc has stabilizing and analgesic effects.
