The effects of red date bark are to nourish the heart and spleen, moisten dryness, and nourish yin. In clinical practice, it can be paired with licorice, which is a good tonic for people with weak qi and blood, and can also harmonize the spleen and stomach. The skin of jujube is more of a nutritional benefit than the jujube alone. You can use date skin in soup or porridge to make it more digestible. The skin of red dates should not be used in the clinic because too much of it is hard and can hurt the spleen and stomach and affect some of the digestion, or it should be stewed with the porridge to make it softer.
