The best time to drink date palm is generally considered to be around 8:00 p.m., i.e., 1-2 hours before going to sleep, depending on individual circumstances. Date palm is often used clinically to treat insomnia and has the effect of nourishing the heart and calming the mind, astringent sweat, laxative and also has obvious sedative and hypnotic and anti-anxiety effects, especially for patients with insomnia and depression. Drinking sour date seeds about 1-2 hours before bedtime helps the gastrointestinal tract to better absorb the medicinal effects of sour date seeds and better play the role of treating insomnia. However, date palm should not be consumed for a long period of time, especially for hot bodies, and long-term consumption of date palm can aggravate dampness and heat in the body. Therefore, when consuming sour date seeds, it is advisable to consult a doctor of traditional Chinese medicine to determine whether you belong to a hot insomnia body. Do not take it blindly on your own to avoid damaging your health.
