Plantago ovata is an annual herb native to Asia, the Mediterranean region, and North Africa and noted to be present in the United States in California, Arizona, Nevada, Utah, and Texas. Psyllium grows in sandy and silty soils. The seed from Plantago ovata is commonly referred to as blond psyllium. India dominates the world market in the production of psyllium husk powder. One of the most well known over the counter fiber products, Metamucil, contains psyllium and was introduced to the US market 80 years ago. The seed and husk have been used traditionally in India, Europe, China and the United States for multiple digestive purposes due to both the soluble and insoluble fiber content. The whole seed is more nutritious than the husk, although both contain nutrients.
