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.
These teas are the most commonly used to relieve constipation: 1  Senna tea acts as a stimulant laxative, which works by stimulating the intestines to move stool along. 2  Some people use dandelion tea to relieve water retention, but it can act as a mild laxative, too. 3  Cascara tea can have a strong laxative effect.
