Plantago ovata

Plantago ovata, known by many common names including blond plantain, desert Indianwheat, blond psyllium, and ispaghul, is a medicinal plant native to Western Asia and Southern Asia. The plant can be found growing wild in the southwestern United States, where it is considered a possibly introduced species.

It is a common source of psyllium, a type of dietary fiber. Psyllium seed husks are indigestible and are a source of soluble fiber which may be fermented into butyrate – a pharmacologically active short-chain fatty acid – by butyrate-producing bacteria.
