Never heard of it, and there are constipation fruit trees. I only know that eating fruits can relieve constipation, such as bananas, apples, pears and peaches. Eat more fruits, or eat more vegetables, fried spinach, cabbage, radish and so on. Can relieve constipation, and need more exercise to relieve constipation. Drinking a glass of honey water every day can also relieve constipation.
