'This is not just a wash-out,' says therapist Mary-Chase Hopkins. 'It can lead to a total re-evaluation of what you put into your body when you see what comes out.' Colonics are an invasive detoxer, pumping out the waste products your body has accumulated. Over time, these can lead to constipation, skin problems, irritable bowel syndrome and lethargy. A sophisticated series of tubes carries warm water in and out of the colon for 40 minutes through a rectal hose, after which a hit of acidophilus, a bacteria that helps improve digestion, restores gut flora. 'What many people don't realise,' says Hopkins, 'is that, ideally for the colon, a bowel movement happens after every meal. If not, you have some degree of constipation.' £75 at The Hale Clinic, Tel: 0870 167 6667. For national referrals: www.colonic-association.com
