Clash of the titans: Jeremy Paxman, left, described Huw Edwards, right, as 'like an evangelical preacher on a wet Sunday in Merthyr Tydfil'. The attack came in a trenchant newspaper article in which the Newsnight presenter described media books as 'unreadable' and criticised his own employer for missing out on big stories.
Laxative (purgatives, aperients) are substances that loosen stools and increase bowel movements. They are used to treat and prevent constipation. Laxatives vary based on how they work and the side effects they have. Certain stimulant, lubricant and saline laxatives are used to evacuate the colon for rectal and bowel examinations, and may be supplemented by enemas under certain circumstances. Sufficiently high doses of laxatives may cause diarrhea.
Mineral oil and castor oil are sometimes used as laxatives, but they shouldn't be used often. If mineral oil is used often, it can cause deficiencies of vitamins A, D, E, and K. Castor oil, which is a stimulant laxative, can lead to chronic constipation because it can cause you to lose muscle tone in your bowel.
