For constipation to know the cause of formation, stool formation requires fiber, which is mainly derived from green leafy vegetables, such as spinach, celery and other high fiber content. It is recommended that patients consume 1 pound of raw leafy greens a day, cooked and divided into 2-3 meals. For patients who do not eat vegetables or do not have the habit of eating vegetables, it is recommended that the vegetables be chopped and wrapped into dumplings and wontons, which can start with 3 taels and then gradually become 0.5-1 pound, which can generally develop a good habit of eating vegetables within 1 month.
