Psyllium 'Psillio'

The leaves of Fleawort or Psyllium can be eaten in salads. Furthermore, it is a plant-based food additive that has appeared relatively recently in the food industry. The plant originates from Iran and India. Psyllium pods contain very small seeds, also called psyllium. The pods provide a dietary fiber that is often added to bread, but also to other products. The pod also contains glycosides and gum, from which the food industry makes gels used as thickeners and texture enhancers.
The fiber resembles fibers we know from, for example, bran or oatmeal, but the amount of water they can absorb is much higher. Every 100 grams of psyllium husk contains 71 grams of water-soluble fiber; an equal amount of oatmeal contains only 5 grams of fiber. And psyllium fiber can absorb up to ten times its own volume in water!
It is only very recently that science has discovered the unique properties of these fibers. They are not broken down by your digestive system and therefore have absolutely no nutritional value.
But psyllium is also said to lower blood cholesterol levels. The FDA in the USA therefore allows psyllium-containing products to use a "healthy" label, whereas this is strictly prohibited for most other products. It should be noted that the effect only occurs in combination with healthy eating habits, such as not eating too much saturated fat.
The combination of a healthy diet with psyllium can lower your total cholesterol level by 4% and your LDL cholesterol level by 7%. The fibers reduce the absorption of cholesterol and bile acids in the intestines, which lowers cholesterol levels.
Lots of fiber in your diet is healthy. Many fruits and vegetables provide good fiber, but apparently psyllium has something more to offer because these fibers are water-soluble.

Isabgol (Psyllium) is obtained from the seeds of the plant. The edible isabgol is obtained through a milling process. The top layer of the seeds is purified by sieving and winnowing. The husk consists of pure dietary fiber, largely composed of hemicellulose. They act as a sponge in the intestinal tract, absorbing water and waste products in the intestines. This forms a soft, bulky mass that passes more quickly through the colon (and prevents potentially toxic waste products from accumulating in the colon).
In summary:
• High water absorption for a better effect
• Lowers blood cholesterol levels
• Cleanses the intestines of toxic components with pure bodily functions
• Non-addictive
• 100% natural plant-based product
A bit of history: in Ayurveda (a holistic system of medicine from India), the gummy seeds are used as a laxative, emollient, and hemostatic agent, especially for chronic colitis. In modern medicine, the plant is used as a mild laxative and sometimes as an additional treatment for urinary tract infections and inflammation of the genitourinary tract. It reduces inflammation of the mucous membranes of the intestinal tract.
A few more (pseudo)scientific claims about nutritional value:
Psyllium husks are an effective bulk-forming laxative. It contains vegetable gum, fixed fatty oil, and proteinaceous matter in large quantities. The psyllium fiber is a gel-forming hydrophilic muciloid that dissolves in water... Isabgol has a remarkable effect on the gastrointestinal system. It is a naturally healthy fiber that is not absorbed in the intestine. It has no known interactions with other medications and does not affect the absorption of vitamins and minerals.
Isabgol is internationally acclaimed as the best remedy for constipation without any side effects. Dr. K.M. Nadkarni's Indian Materia Medica states that isapgula seeds are used for mucous membrane inflammation, chronic dysentery, intestinal flux, diarrhea, inflammation of the bladder, urinary tract, and kidneys, inflammation and functional disorders of the digestive organs, and fever.
