My friend as long as I know Psyllium seed is a common ingredient in over-the-counter bulk laxative products. One preliminary trial found that psyllium seeds relieved constipation when it was due to lifestyle factors (e.g., inadequate fiber, sedentary lifestyle), but not when an actual disease was the cause. Numerous double-blind trials have found that supplementation with psyllium can lower total cholesterol and LDL (“bad”) cholesterol. However, levels of HDL (“good”) cholesterol are not affected by psyllium supplementation.
