1 Star
Indigestion, Heartburn, and Low Stomach Acidity
Refer to label instructions
Wormwood is believed to stimulate digestion and relieve spasms in the intestinal tract.

Bitter herbs are thought to stimulate digestive function by increasing saliva production and promoting both stomach acid and digestive enzyme production. As a result, they are particularly used when there is low stomach acid but not in heartburn (where too much stomach acid could initially exacerbate the situation). These herbs literally taste bitter. Some examples of bitter herbs include greater celandine, , gentian,dandelion, blessed thistle, yarrow, devil's claw, bitter orange, bitter melon, juniper, andrographis, prickly ash, and centaury.. Bitters are generally taken either by mixing 1–3 ml tincture into water and sipping slowly 10–30 minutes before eating, or by making tea, which is also sipped slowly before eating.

is sometimes used in combination with carminative (gas-relieving) herbs for people with indigestion. One double-blind trial found that a combination with peppermint, caraway, and fennel was useful in reducing gas and cramping in people with indigestion. The amounts used are the same as the general recommendations for bitters when they are employed for the treatment of indigestion.

As a traditional medicine, wormwood was used by herbalists as a bitter to improve digestion.2 4 It is often combined with herbs such as peppermint or caraway to treat heartburn and even irritable bowel syndrome, though these uses are not well demonstrated. Consult with a healthcare professional knowledgeable in herbal medicine before taking wormwood.

Traditional Use (May Not Be Supported by Scientific Studies)

Wormwood is perhaps best known because of the use of its oil to prepare certain alcoholic beverages, most notably vermouth and absinthe. Absinthe, popular in the 19th century in Europe, caused several cases of brain damage and even death and was banned in most places in the early 20th century.1 Wormwood oil continues to be used as a flavoring agent for foods, although in much smaller amounts than were found in absinthe.

As a traditional medicine, wormwood was used by herbalists as a bitter to improve digestion, to fight worm infestations, and to stimulate menstruation.2 It was also regarded as a useful remedy for liver and gallbladder problems.

How It Works

Botanical names:
Artemisia absinthium

How It Works

The aromatic oil of wormwood contains the toxins thujone and isothujone. Very little of this oil is present in ordinary wormwood teas or tinctures.3 Also existent in the plant are strong bitter agents known as absinthin and anabsinthin. These stimulate digestive and gallbladder function.4 Modern herbal medicine rarely uses wormwood alone. It is typically combined with herbs such as peppermint or caraway to treat heartburn and even irritable bowel syndrome. Clinical trials are lacking to support the use of wormwood for any indication, however.

How to Use It

A wormwood tea can be made by adding 1/2 to 1 teaspoon (2.5 to 5 grams) of the herb to 1 cup (250 ml) of boiling water, then steeping for ten to fifteen minutes.5 Many doctors recommend drinking three cups (750 ml) each day. Tincture, 10–20 drops in water, can be taken ten to fifteen minutes before each meal.6 Either preparation should not be used consecutively for more than four weeks.7

Side Effects

Botanical names:
Artemisia absinthium

Side Effects

Longer-term use (over four weeks) or intake of amounts higher than those recommended can cause nausea, vomiting, insomnia, restlessness, vertigo, tremors, and seizures.8 Thujone-containing oil or alcoholic beverages (absinthe) made with the oil is strictly inadvisable—the oil is addictive and may cause brain damage, seizures, and even death.9 Short-term use (two to four weeks) of a wormwood tea or tincture has not resulted in any reports of significant side effects. One study found there were no side effects when using less than 1 ml tincture three times per day for as long as nine months to promote digestive function.10 Nevertheless, consult with a healthcare professional knowledgeable in herbal medicine before taking wormwood. Wormwood is not recommended during pregnancy and breast-feeding.11
