Madai ya Valeriani
People take valerian mostly as a sedative and sleep aid, especially in parts of Europe.
Some people take valerian for headaches, depression, menopausal symptoms, premenstrual syndrome, irregular heartbeat, and trembling. It is usually used for short periods of time (2 to 6 weeks).
Ushahidi wa Valeriani
Studies have suggested that valerian improves sleep quality and shortens the time needed to fall asleep. For example, in one study, menopausal women with difficulty sleeping had better sleep quality when takingvalerian. However, whether valerian is effective for insomnia is still not proven.
There is not enough scientific evidence to determine whether valerian is effective for headaches, depression, irregular heartbeat, and trembling. There is now interest in studying valerian to treat obsessive-compulsive disorder, and one study suggests that valerian has some effects that counteract obsessive and compulsive tendencies.
