Arsenicum album: This remedy may be indicated if a person feels anxious, restless yet exhausted, and is worse from the smell and sight of food. Burning pain is felt in the stomach and esophagus, which often is relieved by warmth and sitting up. Vomiting and diarrhea are possible. Upsets from spoiled food or from eating too much fruit often respond to this remedy.

Bryonia: When this remedy is indicated, the stomach feels heavy, with rising acid and a bitter or sour taste. Pain and nausea are worse from motion of any kind. The person may have a dry mouth and be thirsty for long drinks, which may increase discomfort. Bryonia is strongly suggested if a person is grumpy and wants to stay completely still and not be touched or talked to.

Carbo vegetabilis: Sour belching bringing only small relief, burning pain in the stomach and abdomen, and flatulence after eating may be seen when this remedy is needed. The person feels cold and faint, with a strong desire for fresh or moving air. Digestion may be slow and incomplete, with nausea or cramping.

Colocynthis: Cutting, cramping pain in the stomach and abdomen, with relief from hard pressure or from doubling over, indicates a need for this remedy. A bitter taste in the mouth, a feeling that the intestines are about to burst, or a sensation that stones are grinding together in the abdomen may be present. Indigestion may be worse when the person feels upset, especially after suppressing anger.

Lycopodium: This remedy is indicated for many digestive troubles. The person’s appetite may be ravenous, but eating even a small amount can cause a feeling of fullness and bloating. Rumbling gas may form in the abdomen, pressing upward and making breathing difficult. The person often has a strong desire for sweets, is sleepy after meals, and feels worst in the late afternoon and evening.

Natrum carbonicum: This remedy can be helpful to mild people who have trouble digesting and assimilating many foods and have to stay on restricted diets. Indigestion, heartburn, and ulcers can occur if offending foods are eaten. Milk or dairy products can lead to flatulence or sputtery diarrhea that leaves an empty feeling in the stomach. Cravings for potatoes and sweets are common; also milk, but it makes these people sick, so they have usually learned to avoid it.

Natrum phosphoricum: A sour taste in the mouth, an acid or burning sensation in the stomach, sour vomiting, regurgitated bits of food, and a yellow coating on the tongue are all indications for this remedy. The person may have problems after consuming dairy products or too much sugar. Another indication for Natrum phos is a craving for fried eggs.

Nux vomica: This remedy is often useful for indigestion, and is especially suited to those who overindulge in stimulants, food, and alcohol. Chilliness, irritability, and sensitivity to odors, sound, and light are often seen. Pain and weight can be felt in the stomach, with cramps or constricting pains. The person often feels an urge to vomit or move the bowels (which may make the person feel better, but is rarely successful).

Phosphorus: Burning pain in the stomach that feels better from eating ice cream or other cold, refreshing foods suggests a need for this remedy. The person is usually thirsty for cold drinks, but often feels nauseous or vomits once liquids warm up in the stomach. People needing Phosphorus may have a tendency toward easy bleeding and sometimes develop stomach ulcers.

Pulsatilla: Indigestion that is worse from eating rich and fatty foods, with a feeling of a lump or pulsation in the stomach, suggests a need for this remedy. Discomfort often is worse from warmth, especially in a stuffy room, and the person may feel better from gentle walking in open air. A bitter taste in the mouth can take the pleasure out of eating. A person who needs Pulsatilla usually does not feel thirsty and may be tearful and emotional.
