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 2^nd 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.<br>
