Diarrhea is an annoying and debilitating condition that occurs when there is a decrease in the consistency of the stool due to an increase in the amount of water inside the intestinal lumen. The causes of diarrhea are almost always infectious, but the disorder can also arise as a result of food poisoning, intolerances to certain foods or after taking drugs.
Diarrhea is divided into osmotic, secretory, inflammatory and diarrhea due to impaired motility. In the first case, the intestinal cells draw water into the intestinal lumen since the osmorality of the latter exceeds that of the plasma. Behind this process, the reverse of what normally occurs, there is often a malabsorption of some nutrients including carbohydrates and fats. Secretory diarrhea, on the other hand, occurs when ingested bacterial toxins or irritating or toxic substances cause an intestinal infection. To defend itself, the body tries to expel these substances or bacteria, through an increase in hydrosaline secretion in the colon. Inflammatory diarrhea occurs when the intestinal mucosa is damaged, for example in the case of food allergies such as celiac disease or diseases that cause inflammation including Crohn's disease. Finally, diarrhea can also be given by the increase in intestinal motility, which occurs for example in irritable bowel syndrome: this increase decreases the time of intestinal transit, preventing all excess water from being reabsorbed in an adequate way and effective.
When and how to intervene
In general, diarrhea is an acute condition that resolves within a few hours or at most within a few days. If the symptom persists beyond two weeks, it is called chronic diarrhea. To treat diarrhea it is essential to act on the causes rather than the symptom. In case of frequent diarrhea it is therefore good to contact a doctor, who is responsible for identifying and treating the causes and possibly prescribing a therapy. Resorting to a medical examination is also advisable if the diarrhea does not resolve spontaneously within three days. In general, in addition to acting on the causes, the therapies aim to replenish lost fluids and electrolytes and to alleviate the symptom through antidiarrheal remedies, including natural ones.
Herbal medicine and phytotherapy use various natural remedies for diarrhea that are administered both in acute and if the disorder occurs recurrently. These are herbal drugs traditionally used to treat diarrhea for short periods. Many of these natural remedies contain high amounts of tannins or pectins. Tannins are molecules capable of creating a protective layer on the intestinal mucosa, temporary and composed of proteins. This layer allows to reduce the stimuli that induce an increase in intestinal motility, relieving spasms. Pectins, on the other hand, facilitate the reabsorption of electrolytes and water, increasing the consistency of the stool.
Green tea and black tea
Green tea and black tea leaves (Camellia sinensis) are an excellent natural remedy against diarrhea: its intake in the form of an infusion makes it possible to prolong intestinal transit, favoring the reabsorption of excess fluids. In case of diarrhea, up to 8 grams of tea can be consumed per day, with which 1-2 liters of infusion are prepared.
Plants of the genus Potentilla are herbaceous rich in tannins useful in the treatment of diarrhea. In particular, the leaves and flowers of Potentilla anserina or argentina and the rhizome of Potentilla tormentilla (or tormentilla) are used
The oak bark, obtained from the young branches and buds of Quercus robur, is used in the treatment of mild acute diarrhea, taking about 3 grams of dried drug per day.
Agrimonio (Agrimonia eupatoria) is another plant with a high content of tannins useful for counteracting acute episodes of mild diarrhea. They take 3 grams per day, as a dry drug for two or three days.
The aerial parts of Alchemilla vulgaris, collected during flowering, are used for their content of tannins, flavonoids and bitter principles useful in the treatment of mild diarrhea. For this purpose it is taken at a dosage of 5-10 grams of dried drug for no more than three or four days.
Mild acute diarrhea can also be treated by taking wild blackberry leaves (Rubus fruticosus), which are rich in tannins, flavonoids and triterpenes. They take 4-5 grams per day for up to four days.
Carob, fruit of the Ceratonia siliqua or carob, is a pod rich in pectins, mucilage and sugars. Dried, pulverized and dispersed in water, they are a remedy used against diarrhea that for children, to be taken for two days every two hours, without exceeding 2 grams of drug daily.
Immature bananas are rich in pectins useful in case of diarrhea. You can eat two a day for three days to reduce the amount of stools, the number of discharges and the duration of diarrhea.
