Melatonin
Melatonin is an endogenous hormone that is produced from the amino acid L-tryptophan via the intermediate 5-HTP in the pineal gland and, to a lesser extent, in the retina and intestines. Melatonin production and release is light-dependent, with darkness stimulating melatonin production and release, while daylight and blue screen light inhibit it. During the day, melatonin levels are around 3-12 times lower than at night. The release of melatonin initiates the regeneration phase and falling asleep and is responsible for the deep sleep phase. With advancing age, the body's own melatonin production decreases.
Lavender
The species true lavender (Lavandula angustifolia) belongs to the Lamiaceae family and originally comes from the coastal regions of the Mediterranean. The use of aromatic inflorescences has a long tradition, particularly in France and England, as they have a number of health-relevant properties.
Valerian
True valerian, also known as medicinal valerian (Valeriana officinalis), belongs to the honeysuckle family (Caprifoliaceae). The name "Valeriana" is derived from the Latin word "valere", which means "to be healthy". Its root is rich in various ingredients such as essential oils, iridoids, lignans, caffeic acid derivatives and small amounts of amino acids, flavonoids and alkaloids. It is assumed that the harmonious interaction of all these components is responsible for the medicinal properties of valerian root. Even in ancient times, valerian was regarded as a sought-after panacea and therefore has a long tradition in medicine.
Peppermint
Peppermint (Mentha piperita) belongs to the Lamiaceae family and is a cross between water mint and spearmint. Known for its refreshing flavour and characteristic fragrance, peppermint owes its main active ingredients to its essential oil, which contains menthol as its main component. Peppermint has been said to have numerous medicinal properties since ancient times. In many cultures, it is highly valued both as a culinary herb and for its therapeutic properties.
According to the European Food Safety Authority (EFSA), melatonin:
- reduces time needed to fall asleep
- alleviates the feeling of jet lag
