Argentum nitricum: If a person has diarrhoea 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 diarrhoea may look green. Diarrhoea that occurs immediately after eating or drinking, or after eating too much sugar, will often respond to Argentum nitricum.

Arsenicum album: Diarrhoea 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 odour. Simultaneous diarrhoea and vomiting is another strong indication. Arsenicum is often useful when diarrhoea has been caused by spoiled or tainted food.

Bryonia: This remedy is often helpful for diarrhoea during flu (especially when the person feels grumpy and wants to lie still and be left alone). It may also be helpful for diarrhoea 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 diarrhoea with abdominal pain and wind 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 diarrhoea 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 diarrhoea follows anger (especially if the feelings were not expressed).

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

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

Phosphorus: This remedy can be soothing if a person has a weak or empty feeling in the abdomen, followed by diarrhoea 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 diarrhoea that is usually not accompanied by pain suggests the use of this remedy. The abdomen rumbles and gurgles before the diarrhoea passes, and urging may soon be felt again. Bouts of diarrhoea are often worse in the morning, and also in hot weather.

Pulsatilla: If diarrhoea occurs after eating rich and fatty foods, this remedy can be helpful. Queasiness and abdominal pain are likely to occur, and the diarrhoea 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 diarrhoea 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 haemorrhoids that burn and itch.
