Psyllium husk is a type of white fiber extracted from the seeds of the medicinal plant Plantago Ovata. It’s a layer of mucilage around psyllium seeds, separated through a mechanical process. The husk mainly consists of a fiber called hemicellulose, a complex carbohydrate found in whole grains, fruits, and vegetables. Essentially, psyllium husk is a pure, natural dietary fiber and is widely used worldwide as a bulk-forming laxative. You can consume psyllium husk in its natural form or in flavored form by mixing it with liquids like water, juice, or milk.
