Er Su Jiu Ju, a traditional Chinese incense formula, has been claimed to have the effect of improving sleep quality. Here are some possible reasons supported by relevant data.
1. Ingredients with Sedative Effects
- Jujube: Jujube is one of the possible ingredients in Er Su Jiu Ju. In traditional Chinese medicine, jujube has been used for thousands of years to promote sleep. Scientific research has provided evidence for its sedative effect. For example, some studies have shown that jujube contains certain phytochemicals. Saponins and flavonoids in jujube can trigger changes in neurotransmitters. One study indicated that jujube could extend sleep time in mice. In a research on post – menopausal women, after taking jujube – seed capsules, the mean scores of sleep quality decreased significantly compared with the control group (p – value < 0.001), which means their sleep quality improved. These bioactive compounds can act on the body’s nervous system, making it easier for people to fall asleep and stay asleep.
- Sandalwood: Sandalwood is often used in Er Su Jiu Ju. It contains natural compounds that have a calming effect. Aromatherapy studies have shown that the smell of sandalwood can reduce the activity of the nervous system. Inhaling sandalwood aroma can lower the heart rate and blood pressure, which are physiological indicators related to relaxation. When the body is in a more relaxed state, it is more conducive to falling asleep. Although there may not be a large – scale double – blind clinical trial specifically for Er Su Jiu Ju’s sandalwood component and sleep, in many traditional medicine records and small – scale sensory evaluation experiments, the soothing effect of sandalwood on the mind has been repeatedly verified.
- Agarwood: Agarwood is also an important ingredient. The aroma of agarwood has long been regarded as having a relaxing and stress – relieving effect. In traditional Chinese medicine theory, it can soothe the liver and relieve depression. Modern research on the volatile components of agarwood shows that some of its compounds can interact with the olfactory nerve, and then transmit signals to the brain, regulating the body’s stress response. High – stress levels are often one of the main causes of sleep disorders. By reducing stress, agarwood in Er Su Jiu Ju may help improve sleep quality.
2. Impact on Mood and Stress Reduction
- The complex aroma of Er Su Jiu Ju can have a positive impact on mood. A study on the relationship between smell and emotion found that pleasant scents can increase the secretion of neurotransmitters such as serotonin in the brain. Serotonin is not only related to mood regulation but also plays a crucial role in the sleep – wake cycle. When the level of serotonin in the body is appropriate, people are in a better mood and more likely to have a good night’s sleep. The combination of various natural ingredients in Er Su Jiu Ju forms a unique and pleasant aroma, which may promote the secretion of serotonin, thus improving sleep quality.
- Stress is a major factor affecting sleep. The aroma of Er Su Jiu Ju can help reduce stress hormone levels. For example, in some aroma – exposure experiments, subjects exposed to certain natural incense aromas (similar to the components of Er Su Jiu Ju) showed a decrease in cortisol levels. Cortisol is a stress – related hormone. High levels of cortisol can disrupt the normal sleep rhythm. By reducing cortisol levels, Er Su Jiu Ju can help the body return to a more relaxed state, making it easier to fall asleep and stay asleep.
In conclusion, the ingredients in Er Su Jiu Ju and their combined effects on the nervous system, mood, and stress levels may be the reasons why it can improve sleep quality, as supported by relevant scientific research and traditional medicine experience.
