Caraway seeds (Carum carvi) are a natural substance long used in cooking and in ayurvedic medicine. Caraway seeds are typically consumed as a food or spice, but caraway oil and caraway seed powder are also sold in dietary supplement form. Some proponents suggest that consuming caraway seeds or caraway supplements can promote weight loss and offer other health benefits.
Uses for Caraway
Caraway is often touted as a natural remedy for the following health problems:
Caraway is also said to act as a carminative, which is a substance that prevents the formation of gas in the gastrointestinal tract. By inhibiting gas formation, caraway is thought to prevent bloating (and, in turn, keep your stomach from appearing larger after eating).
When used as a carminative, caraway oil is often taken in combination with peppermint oil.
Benefits of Caraway
To date, very few scientific studies have tested the health effects of caraway. However, some preliminary research indicates that caraway may offer certain health benefits. Here's a look at some key findings from the available studies:
1) Caraway and Indigestion
A combination of caraway oil and peppermint oil may help treat indigestion, according to a study published in the German journal Drug Research in 1999. For the study, 120 patients with a tendency toward indigestion took either the peppermint-caraway formula or cisapride (a medication typically used to treat heartburn) every day for four weeks. Study results showed that the two treatments were similarly effective when it came to alleviating symptoms of indigestion.
It should be noted that it's unknown whether caraway oil on its own might be useful in the treatment of indigestion.
2) Caraway and Diabetes
Preliminary research from animal-based studies raises the question of whether caraway may also be of some benefit to people with diabetes. For instance, a 2006 study on diabetic rats (published in the Journal of Ethnopharmacology) found that treating the rats with caraway extract led to a significant decrease in cholesterol levels.
In addition, a more recent study on diabetic rats (published in Saudi Medical Journal in 2011) found that treatment with caraway caused a significant reduction in blood sugar levels and helped promote weight loss. However, the study's authors note that caraway cannot be recommended to diabetes patients until further research is conducted.
Is Caraway Safe?
Caraway is considered safe when consumed as a food. However, since caraway may lower your blood sugar, people with diabetes should be cautious when consuming high amounts of caraway. Given caraway's potential to affect blood sugar levels, it's also important to avoid consuming caraway for at least two weeks prior to undergoing surgery.
In addition, caraway oil should be avoided by women who are pregnant or breastfeeding.
Where to Find Caraway
Caraway seeds are available in most grocery stores. Caraway supplements are widely available for purchase online, and can also be found in many natural-foods stores and in stores specializing in dietary supplements.
Should You Use Caraway for Health Purposes?
Although it's too soon to recommend caraway supplements for any health-related purpose, it's possible that including caraway seeds in your diet could help enhance your health to some degree.
If you're considering the use of caraway supplements for the treatment of a specific health condition, make sure to consult your physician before starting your supplement regimen. Self-treating a chronic condition with caraway supplements and avoiding or delaying standard care may have serious health consequences.
