Abstract:
The sleep-inducing effect and safety of an herbal tea containing valerian and lemon balm were subject to a preliminary open pilot study. Subjects were 14 female volunteers (age 35 ± 11, BMI 21 ± 3 kg/m2) who complained of poor sleep. After obtaining informed consent, subjects took daily 2 cups of herbal teas containing valerian and lemon balm for 1 week, followed by a control week, during which they had two cups of hot water. OSA sleep questionnaires and VAS scales were recorded every day. Sleep quality increased at the 2nd day after starting the tea, and sleep induction and sleep maintenance were improved in particular. Those whose complaints were severe experienced greater relief than those who complaint a little. Some cases reported transient sleepiness and gastrointestinal complaints. However, these symptoms disappeared spontaneously. The safety and effectiveness of this sleep-inducing herbal tea was ascertained.
