Jujube, What Makes It Such a Great Sleep Aid?

What is this funny little fruit, known as jujube, and why is it known for promoting a deeper, more restful sleep?  In Chinese herbal medicine it is the seed of the fruit or spiny zizyphus.  Laboratory studies of zizyphus extract have confirmed the sedative effects.  In fact,  the latest research from France concluded the seeds of the fruit are rich in fatty acids and a host of other beneficial compounds which can benefit those who are looking for a natural sleep aid.

Jujube seeds are about the same size as a typical apple seed.  The seeds have been used in Traditional Chinese Medicine and in other ancient cultures for  hundreds of years.  The seeds are most commonly used for their sedative effects especially common as a sleep aid.    Yet, unlike so many other sedative plants or man made drugs, zizphus is extremely safe.     Drinking zizphus tea has been reported to have no toxicity even in huge doses such as 50 grams per kilogram of body weight, even for 30 consecutive days.

Modern pharmacology evaluation of zizyphus seed oil and zizyphus extract suggest that with prolonged feeding (to mice)  they can reduce serum triglycerides and cholesterol (mainly LDL), and reduce fatty degeneration of the liver. These same properties have also been attributed to the triterpenes of ganoderma and ginseng.  Connect here to articles on ginseng and ganoderma.

Jujube has increasingly become popular as a source of over-the-counter natural sleep aid.  In this just released study, different extracts of the Zizyphus exerted antioxidant activity. Hence, it is possible that the antioxidant activity of Zizyphus might be due to the presence of different vitamins and fatty acids.   The study also showed that Zizyphus decoction (cooked in water) exerted an immmuno-supressive activity.  Jujube is one of the main ingredients in our natural herbal sleep tea.
