My dear.  Isabgol known as Psyllium Husk has excellent result for Constipation as it contains fiber.  It has dual amazing effect on gastrointestinal tract......  Controls diarrhoea n frequency of loose stools and it also relieves Constipation. It can b said as a food supplement.  It has few nutritional  effects but its dose should not b more than 15 gms per day.  Or otherwise it may cause deficiency of other nutrients.        It should b No Doubt Soaked for atleast half an hour before taking it.  It should b taken with plenty of water or it might b choked up in the gastrointestinal tract.   Dependency is not much issue but still one can take it continously for a week.  But If constipation is a daily n chronic problem u can take it every morning on empty stomach.  And take your breakfast after 1 hour of isapgol consumption. Hope u got ur answer n cleared ur doubts.
