Argentum nitricum: If a person has diarrhea when anticipating a stressful event (such as giving a speech or a public performance, taking a test, or attending a party) this remedy should come to mind. Bloating and flatulence are usually seen, pain may be felt in the region of the groin, and the diarrhea may look green. Diarrhea that occurs immediately after eating or drinking, or after eating too much sugar, will often respond to Argentum nitricum.

Arsenicum album: Diarrhea accompanied by anxiety, restlessness, and exhaustion suggest a need for this remedy. Burning pain is felt in the digestive tract, and the person may be thirsty for frequent small sips of tea or water. The stools may be watery and have a putrescent odor. Simultaneous diarrhea and vomiting is another strong indication. Arsenicum is often useful when diarrhea has been caused by spoiled or tainted food.

Bryonia: This remedy is often helpful for diarrhea during flu (especially when the person feels grumpy and wants to lie still and be left alone). It may also be helpful for diarrhea that occurs when a person gets overheated, then drinks a lot of cold water. Symptoms often are worse in the morning. The person’s mouth may be very dry.

Chamomilla: Hot, green, watery diarrhea with abdominal pain and gas suggests a need for this remedy. The person’s face will be red and flushed (sometimes only on one side) and problems may be worse from warmth. Children who need this remedy will often seem extremely angry, and scream or hit. Adults are irritable and hypersensitive.

Colocynthis: Cutting and cramping pains in the abdomen precede the diarrhea when this remedy is indicated. The person feels relief from doubling over, or from putting hard pressure on the abdomen. This remedy is often helpful when diarrhea follows anger (especially if the feelings were not expressed).

Gelsemium: This remedy is often indicated if trembling and weakness accompany diarrhea, especially when nervousness, fear, or emotional upset is the cause. Gelsemium is also useful during flu with diarrhea, droopy lethargy, fever, chills, and headache.

Ipecacuanha: If a person has diarrhea accompanied by extreme or constant nausea, this remedy may bring relief. Cutting, clutching pains are worse around the navel, and the diarrhea looks frothy or green.

Phosphorus: This remedy can be soothing if a person has a weak or empty feeling in the abdomen, followed by diarrhea that runs out “like an open faucet.” People who need this remedy are often thirsty, and may be fearful when ill.

Podophyllum: Profuse, gushing, watery diarrhea that is usually not accompanied by pain suggests the use of this remedy. The abdomen rumbles and gurgles before the diarrhea passes, and urging may soon be felt again. Bouts of diarrhea are often worse in the morning, and also in hot weather.

Pulsatilla: If diarrhea occurs after eating rich and fatty foods, this remedy can be helpful. Queasiness and abdominal pain are likely to occur, and the diarrhea has a changeable appearance. The person usually is not be thirsty, feels worse from being warm or in a stuffy room, and is better in open air. A need for attention, sympathy, and comforting is a strong indication for Pulsatilla (a very useful remedy for children).

Sulphur: Urgent, hot diarrhea that occurs in the early morning, making the person rush to the bathroom, suggests a need for this remedy. Burning is often felt in the digestive tract, and the anus can be itchy, red, and irritated. The person may also have hemorrhoids that burn and itch.
