Mangosteen has a laxative effect, but it does not cure constipation. Mangosteen is rich in citric acid and vitamin C. It has a limited role in treating constipation and only has laxative effects. For patients with constipation, it is recommended to eat foods that contain fiber. Fiber is a relatively important and basic condition for the formation of stool, and leafy greens have a high fiber content, such as spinach. Therefore, it is recommended that you need to eat 500g of vegetables every day, and also eat more coarse grains, such as corn, sweet potatoes, coarse grains also have a higher content of fiber.
