Diarrhea
Diarrhea is a relatively common condition that involves frequent passing of loose or watery stools. It may be mild and go away in a couple of days, or it may be persistent and suggest an underlying medical illness.
Types
The condition can be classified as either acute or chronic. In the acute type, symptoms appear rapidly and usually last about five to ten days. This is frequently seen in developing countries and is a major cause of mortality in pediatric patients.
Chronic diarrhea, as the name implies, is diarrhea that takes place over a longer period, such as in inflammatory bowel syndrome (IBS) and Crohn's disease.
Causes
Most commonly, diarrhea is viral and usually resolves spontaneously after a few days. Bacteria are the etiologic organisms in many cases of food poisoning, particularly E. coli. Parasites such as Giardia lamblia may also cause the condition. Travel to endemic areas is a risk factor.
Some people may develop diarrhea due to intolerance to lactose, a type of sugar found in milk and dairy products. Some individuals may also have trouble digesting fructose, another form of sugar found in fruits and certain beverages.
Diarrhea can be present in some patients who have undergone surgical procedures, such as gallbladder removal.
Chronic diarrhea can be seen in various diseases such as Crohn's disease, ulcerative colitis, and celiac disease.
Other less frequent causes include radiation therapy and nerve disorders.
Signs and Symptoms
Patients may have abdominal cramps, stomach pain, vomiting, appetite loss, fatigue, bloating, nausea, and loose watery stools. Some may have blood in the stool, fever, and headache.
Diagnosis
After obtaining the patient's medical history, the physician performs a physical examination. When needed, the patient's stool is examined. Depending on the case, certain procedures may be performed, such as sigmoidoscopy.
Treatment
In the majority of cases, diarrhea resolves on its own without the need for medical intervention. Dehydration should be watched for. The affected person should drink plenty of fluids and avoid medications that are not prescribed. Specific drugs may be given depending on stool test results. Diet and lifestyle changes may help in chronic cases.

Efficacy of Alternative and Other Treatments According to GRADE Ranking
Vitamin A [1, 45, 46, 47, 48, 49, 50, 51]
Please note, this management does not treat the condition itself. It may mildly help in preventing some symptoms, and even then has insufficient evidence to back up this claim at present. This acts as a preventative treatment, not necessarily symptomatic relief.
Recommendation: Strong. Vitamin A may help to prevent diarrhea due to its role in the body's immune function.
Grade of Evidence: High quality of evidence.
Thuja (Eastern White Cedar, Thuja occidentalis) [1, 42, 43, 44]
Please note, this management does not treat the condition itself. It may mildly help with some symptoms, and even then has insufficient evidence to back up this claim at present. Little is known about the full effects of Thuja, so it is not recommended for medicinal use. Thuja can be poisonous if ingested in large amounts.
Recommendation: No recommendation. There is insufficient evidence to support claims that Thuja helps to treat diarrhea.
Grade of Evidence: Very low quality of evidence.
Psyllium (Ispaghula, Plantago psyllium) [1, 36, 37, 38, 39, 40, 41]
Please note, this management does not treat the condition itself. It may mildly help with some symptoms, and even then has insufficient evidence to back up this claim at present.
Recommendation: Strongly in favor. Clinical trials have shown that psyllium is effective in treating side effects of cancer therapy such as diarrhea.
Grade of Evidence: High quality of evidence.
Peppermint Oil [1, 30, 31, 32, 33, 34, 35]
Please note, this management does not treat the condition itself. It may mildly help with some symptoms, and even then has insufficient evidence to back up this claim at present.
Recommendation: No recommendation. There is insufficient evidence to support claims that peppermint helps to treat diarrhea.
Grade of Evidence: Very low quality of evidence.
Mugwort (Artemisia vulgaris) [1, 27, 28, 29]
Please note, this management does not treat the condition itself. It has been proposed only as weak supportive symptomatic support, and even then has been discounted due to potentially life-threatening side effects.
Recommendation: No recommendation. There is insufficient evidence to support claims that mugwort helps to treat diarrhea. More research is needed.
Grade of Evidence: Very low quality of evidence.
Kampo [1, 25, 26]
Please note, this management does not treat the condition itself. It may mildly help with some symptoms, and even then has insufficient evidence to back up this claim at present.
Recommendation: No recommendation. Initial studies indicate a possible reduction of diarrhea severity when using Kampo. However, more studies are needed, and the side effects of the treatment are relatively unknown.
Grade of Evidence: Very low quality of evidence.
Indian Snakeroot (Rauvolfia, Rauvolfia serpentina) [1, 23, 24]
Please note, this management does not treat the condition itself. It may mildly help with some symptoms, and even then has insufficient evidence to back up this claim at present.
Recommendation: No recommendation. There is insufficient evidence to support claims that Indian Snakeroot helps to treat diarrhea in any way.
Grade of Evidence: Very low quality of evidence.
Green Tea [1, 18, 19, 20, 21, 22]
Please note, this management does not treat the condition itself. It may mildly help with some symptoms, and even then has insufficient evidence to back up this claim at present.
Recommendation: Weakly in favor. There is insufficient evidence to support claims that green tea helps to treat diarrhea in any way. Although reports are positive, more studies are needed.
Grade of Evidence: Low quality of evidence.
Gotu Kola (Centella asiatica, Hydrocotyle asiatica) [1, 12, 13, 14, 15, 16, 17]
Please note, this management does not treat the condition itself. It may mildly help with some symptoms, and even then has insufficient evidence to back up this claim at present.
Recommendation: No recommendation. There is insufficient evidence to support claims that Gotu Kola helps in the treatment of diarrhea in any way. More research is needed.
Grade of Evidence: Low quality of evidence.
Goldenseal (Hydrastis canadensis) [1, 5, 6, 7, 8, 9, 10, 11]
Please note, this management does not treat the condition itself. It may mildly help with some symptoms, and even then has insufficient evidence to back up this claim at present.
Recommendation: Weakly against. Animal studies show that Goldenseal may help reduce certain types of diarrhea. However, more studies on humans are needed. Goldenseal may produce toxic effects, including depression, constipation, rapid heartbeat, stomach pain, mouth ulcers, and vomiting.
Grade of Evidence: Low quality of evidence.
Comfrey (Blackwort, Symphytum officinale) [1, 2, 3, 4]
Please note, this herb is toxic if taken orally or if applied to an open wound. It can cause severe liver or kidney damage and lead to death. It may only be used as a cream over intact skin, and does not treat the condition itself. It may mildly help with some symptoms, and even then has insufficient evidence to back up this claim at present.
Recommendation: Strongly against. If taken orally to treat diarrhea, Comfrey can lead to severe liver and kidney damage, and can even lead to death.
Grade of Evidence: Low quality of evidence.
Red Pepper (Capsaicin)
