If it’s a fruit, such as green or green jujube, there’s no problem, but the red jujube is usually a dried jujube that has been dried and dehydrated, it’s warm, it’s good for the spleen and stomach, and it can produce blood. But when it comes to pneumonia, there is usually heat in the lungs and phlegm is produced, so it is not suitable to use this kind of warm stuff at this time. The actual fact is that you should not use red dates at this time, but after you have recovered from pneumonia, it is okay to use red dates for physical conditioning.
