If you are weak, you'd better eat more foods with high protein and nourishing qi and blood, such as pork liver, black beans, eggs, jujube, ginseng, donkey-hide gelatin, milk, pork, beef, mutton and chicken. You can skip spicy food, eat more fresh fruits and vegetables according to your personal preference, and take part in outdoor sports to promote blood circulation and refresh your mind. Usually, jujube can be soaked in water instead of tea.
