The Psyllium husks are thoroughly cleaned and sorted from anti farm fibers, mud, iron particles, dust, particles, stones and other waste products. They are then graded, taking their scientific values into account. Psyllium husks and powders are sorted with the help of these grades.Psyllium consists of 80% water soluble fiber. Psyllium mucilage has a viscosity which is undeterred with 68 degrees F to 122 degrees F, by pH ranging from 2 to 10 and by sodium chloride up to 0.15 m.The husk is composed mostly of a fiber called hemicellulose which is a complex carbohydrate found in whole grains, fruits and vegetables.Hemicellulose is un-digestible, however, it is partially broken down in the colon and feeds the friendly intestinal flora.
