probiotics. Probiotics are beneficial microorganisms. They are naturally present in the intestinal flora. It is possible to consume probiotics in the form of suppléments orfoodstuffs. Their effect on the symptoms of irritable bowel syndrome has been the subject of numerous studies, particularly since the early 2000s.^13-18 . The most recent meta-analyzes conclude that they generally improve the condition of patients, in particular by reducing the frequency and intensity of abdominal pain, flatulence, bloating, and by regulating intestinal transit.^33,34. However, the type of probiotics, their dose, and the length of time they were administered varied greatly from study to study, making it difficult to determine a precise treatment protocol.^13,19. For more information, see our Probiotics sheet.

 Hypnotherapy. The use of hypnotherapy in the treatment of irritable bowel syndrome has been the subject of several conclusive studies, but the methodology of which has limitations.^8,31,32. The meetings are generally spread over a few weeks and supplemented by self-hypnosis at home using audio recordings. Most research notes improvement in abdominal pain, bowel movements, distension (enlargement) of the abdomen, anxiety, depression and general well-being.⁷. In addition, it seems that these benefits persist in the medium term (2 years and more). In the longer term (5 years), the practice of hypnosis would also contribute to reducing the consumption of drugs.^9,10.

 Pepper mint (Mentha x piperita) (essential oil in capsules or enteric-coated tablets). Peppermint has antispasmodic properties and relaxes smooth muscles in the intestines. Commission E and ESCOP recognize its ability to relieve symptoms of irritable bowel syndrome. In 2005, the results of a scientific review of 16 clinical trials involving 651 subjects were published. Eight of 12 placebo-controlled trials yielded convincing results¹².

Dosage

Take 0,2 ml (187 mg) of peppermint essential oil in capsules or enteric-coated tablets, 3 times a day, with water, before meals.

Notes. Peppermint in the form of essential oil can make heartburn worse. It is for this reason that it is prepared in the form of capsules or coated tablets, the contents of which are released in the intestine, not in the stomach.

 Acupuncture. A few studies examining the use of acupuncture to relieve symptoms of irritable bowel syndrome have led to mixed results.^20,21,35. Indeed, the stimulation of recognized and unrecognized acupuncture points (placebo) has often given similar beneficial effects. In addition, the methodological quality of most of the studies leaves much to be desired. Even so, Mayo Clinic experts report that some people manage to relieve their spasms and improve bowel function with this treatment.²².

 Artichoke (Cynara scolymus). Artichoke extract, which is used to relieve digestive disorders, may decrease symptoms of irritable bowel syndrome, according to pharmacovigilance study³⁰.

 Traditional Chinese, Tibetan and Ayurvedic medicine. Several preparations containing different plants are used by practitioners of these traditional medicines. They have been tested in numerous clinical trials conducted mainly in China.^11,23. The results indicate that these preparations are more effective than conventional medication, but the methodology and conclusions of studies conducted in China are considered unreliable.^24,25.

An essay carried out in Australia and published in 1998 in the prestigious Journal of the American Medical Association (JAMA) indicates that traditional medicine can help²⁶. On the other hand, during a trial conducted in Hong Kong and published in 2006, a Chinese preparation containing 11 different plants was not more effective than a placebo.²⁷. The authors of a review of studies point out that the following products have given beneficial results: the 3 Chinese preparations STW 5, STW 5-II and Tong Xie Yao Fang; the Tibetan remedy Padma Lax; and an Ayurvedic preparation called “with two herbs”²². Consult a trained practitioner for personalized treatment.

 Linseed. Commission E and ESCOP recognize the use of flax seeds to relieve symptoms of irritable bowel syndrome. Flax seeds are a good source of soluble fiber that is gentle on the gut. However, since they also contain insoluble fiber, some people may find them irritating to the stomach. See the advice of nutritionist Hélène Baribeau concerning the quantities to consume, depending on the case, in our Lin (oil and seeds) sheet.
