The core function of Valerian Root Extract is to calm the nerves and improve nervous system function, and it is mostly used in products related to sleep aid and emotional regulation. It contains active ingredients such as valerenic acid, which can act on the central nervous system and regulate γ-aminobutyric acid (GABA) receptors. This helps relieve nervous tension and improve issues like difficulty falling asleep and light sleep. Moreover, it works gently and rarely causes drowsiness the next day. In addition, it can assist in alleviating mild anxiety and irritability, and has a certain soothing effect on headaches and muscle tension caused by mental stress. In terms of applications, it is often added as a natural sleep-aiding ingredient to dietary supplements and functional drinks, and is also used in traditional herbal preparations. It should be noted that its effects vary from person to person, so it must be used in appropriate doses. It should not be used together with sedative drugs, and pregnant and lactating women should use it with caution.
