Diet cures more than the doctor. Longan, black dates and red dates can be used to make soup, which can replenish qi and blood. Longan supplements the deficiency of heart-qi, nourishes blood and calms the nerves, improves intelligence and strengthens the body, and black dates are nutritional warehouses for invigorating qi and nourishing blood. Jujube, on the other hand, nourishes blood and calms the nerves, so this compatibility can play a role in invigorating qi and blood, calming the nerves and keeping in good health, and improving intelligence and strengthening the body. I hope I can help you and I hope you can adopt it.
