Date palm has a certain effect of improving sleep and calming the mind, so it can be used as an aid to sleep and calm the mind when given to patients with neurasthenia and chronic insomnia. It is best to use ceramic or glass utensils to make water with date palm, and not metal ones. As date palm also has certain toxic side effects, you should not use too much of it, and must use reasonable portions under the guidance of a medical professional, so make sure to ration the date palm with boiling water. The sour date seed brewed water should not be consumed for a long time, and must be discontinued after drinking for a period of time to avoid toxic side effects. It is best to drink it within half an hour or so before going to bed, taking care not to soak it for too long or for too short a time, putting it into 200-400ml of water is fine. The sour date seed infusion plays a role in aiding the treatment of insomnia, if the underlying disease also needs to be actively treated.
