This Food Heals Hemorrhoids The Journal of Nutraceuticals and Food Science has just published a literature review on how one natural food supplement treats the most severe hemorrhoids. Researchers traced the causes of hemorrhoids back to three habits that they called deranged defecation habits (beautiful term, is not it?). They found that this natural food supplement counteracted these habits. Psyllium husk, a type of fiber commonly sold in powder form, is the secret. According to a study published in the Journal Minerva Gastroenterologica E Dietologica, psyllium husk can be used to treat even the most severe hemorrhoids. First, it is important to understand how your bathroom habits are causing hemorrhoids and making your pre-existing ones even worse.
