Purpura is a hemorrhagic disease, and patients should not eat spicy and dry products, such as wine and pepper. Should eat more products to cool blood and stop bleeding, such as purslane, thistle, bamboo shoots, lotus root, tremella, loofah, water chestnut, shepherd's purse, radish and so on; People who lack qi and don't replenish blood can eat foods rich in colloid, such as bone marrow, meat, skin and pig's trotters. Purpura is a chronic recurrent disease, which leads to anemia after repeated bleeding, and the patient's resistance decreases.
