It has been a commonly used soothing medicinal material in traditional Chinese medicine since ancient times. Its nature is neutral, its taste is sweet and sour, and it is directed to the heart, liver, and gallbladder meridians.Nourishes the mind and calms the nerves, relieves sweat and promotes fluid productionIt has effects such as insomnia, palpitations, night sweats and other symptoms. Modern research shows that jujube seeds are rich in saponins, flavonoids and various amino acids, which have a significant effect on regulating the nervous system and improving sleep quality. The following is a detailed analysis of its core functions and functions.

1. Nourish the mind and calm the mind, improve sleep
The most well-known effect of Ziziphus Seed is to treat insomnia. "Compendium of Materia Medica" records that it "mainly troubles people and prevents them from sleeping". It is often used clinically for difficulties in falling asleep, excessive dreams and easy awakening caused by heart and liver blood deficiency. Its active ingredients can inhibit the excitability of the central nervous system and prolong deep sleep time. For example, the "Suanzao Ren Decoction" that is compatible with Poria cocos and Anemarrhenae is a classic soothing prescription.

2. Concentrate sweat, quench thirst, and regulate body fluids
For night sweats and spontaneous sweating caused by menopause or physical weakness, Ziziphus Seed can reduce abnormal perspiration through its astringent effect. Experiments show that its water decoction can reduce the sweat gland secretion of model animals (see Table 1 for data). At the same time, its glycolic and yin-reducing properties help relieve dry mouth and tongue.

3. Assist in lowering blood pressure and protecting the heart
The total saponins in jujube kernels can slightly dilate coronary arteries and improve blood supply to the myocardium. A 2020 study in "Traditional Chinese Medicine Pharmacology and Clinical Medicine" pointed out that its extract can reduce the systolic blood pressure of hypertensive rats by an average of 12%-15% without significant side effects, making it suitable as an auxiliary conditioning product for cardiovascular health.

Things to note
Although jujube kernels are relatively safe,Use with caution for those with excessive heat and stagnation of fire., long-term use requires consultation with a Chinese medicine practitioner. The recommended daily dosage is 10-15 grams, which can be used to cook porridge or replace tea. Pu Fuzhou, a famous Chinese medicine doctor, once emphasized: "Spiny jujube kernels should be fried, but raw use will cause excitement", suggesting that the processing method affects the efficacy of the medicine.

As a typical representative of the origin of medicine and food, jujube kernel has not only inherited thousands of years of traditional Chinese medicine wisdom, but its value has also been verified by modern science. Rational use can help improve sub-health status, but attention must be paid to individual differences and syndrome differentiation to avoid blind reliance.
