Anise vs. Licorice: A Crucial Distinction
Anise (Pimpinella anisum) is a seed derived from a plant in the Apiaceae family, and while it shares a flavor profile with licorice root due to a compound called anethole, they are botanically and chemically distinct. True licorice root (Glycyrrhiza glabra) contains glycyrrhizin, a compound that can cause the body's potassium levels to drop and lead to a significant increase in blood pressure when consumed in large quantities. This is the source of the common misconception. Anise, fortunately, does not contain glycyrrhizin and is free from this specific risk associated with hypertension. Distinguishing between these two flavorings is the first and most important step for anyone managing their blood pressure.
Potential Cardiovascular Benefits of Anise
Far from being harmful, moderate anise consumption may offer several benefits for cardiovascular health. Research highlights the potential of anise seeds and their extracts to support a healthy heart. These potential benefits are largely attributed to the spice's rich antioxidant and anti-inflammatory compounds. Chronic inflammation is a known contributor to heart disease and arterial damage, so reducing it is a crucial part of maintaining cardiovascular health.
How Anise Can Impact Blood Pressure
While not a replacement for prescribed medication, some studies have explored how anise compounds might influence blood pressure:
- Antioxidant Power: Anise contains beneficial compounds that act as antioxidants, protecting the heart and blood vessels from oxidative stress and free radical damage. This can help improve overall vascular health and circulation.
- Potassium Content: Anise seeds contain a small amount of potassium, which is known to help ease tension in blood vessel walls, further assisting with blood flow.
- Anti-inflammatory Effects: The anti-inflammatory properties of anise can help reduce inflammation within the arteries, promoting better vascular health and reducing the risk of heart disease.
Anise Seed vs. Star Anise: Are They Different for Hypertension?
Another important distinction to make is between common anise seeds (Pimpinella anisum) and star anise (Illicium verum), a star-shaped spice also known for its licorice-like flavor. While both are used culinarily, they come from different plant families and have different chemical compositions.
| Feature | Anise Seed (Pimpinella anisum) | Star Anise (Illicium verum) |
|---|---|---|
| Plant Family | Apiaceae (Carrot Family) | Magnoliaceae (Magnolia Family) |
| Blood Pressure Effect | Generally safe and may offer mild benefits. | Safe in moderation, potential for interaction with medications. |
| Adulteration Risk | Not typically associated with toxic adulteration. | Potential for toxic adulteration with Japanese star anise (Illicium anisatum), which is a known neurotoxin. |
| Primary Compound | Rich in anethole. | Also rich in anethole, but has additional compounds. |
Both are considered safe for moderate dietary use, but extreme caution is advised with star anise due to the risk of adulteration with the toxic Japanese variety, a particular concern with herbal teas and supplements. Always source spices from reputable suppliers.
Precautions and Potential Drug Interactions
While generally safe, high doses of anise or concentrated anise extracts can pose risks, especially for those with high blood pressure or other medical conditions.
Potential Risks
- Drug Interactions: Concentrated anise oil can interact with various medications. For example, it can affect the liver enzymes (CYP2C9) responsible for breaking down certain blood pressure medications, potentially reducing their effectiveness. It can also interact with blood thinners like warfarin, increasing bleeding risk.
- Estrogen-like Effects: Anise has some estrogen-mimicking properties, which means individuals with hormone-sensitive conditions such as breast cancer or endometriosis should use caution and consult a healthcare provider. This can also affect hormone therapies or hormonal birth control.
- Allergic Reactions: People with allergies to other plants in the carrot family, such as celery, fennel, or parsley, may also have an allergic reaction to anise.
Safe Ways to Incorporate Anise into Your Diet
For individuals with high blood pressure, incorporating small, culinary amounts of anise is generally considered safe. Here are some simple ways to enjoy its flavor without risk:
- Anise Tea: Brew a mild tea using a teaspoon of anise seeds. Avoid over-concentrating the brew by boiling for too long.
- Baking: Add a touch of ground anise seed to baked goods like cookies or bread for a distinctive flavor.
- Savory Dishes: Use anise seeds to flavor sauces, soups, and curries. It pairs well with pork and chicken.
- Spice Blends: Include anise in DIY spice rubs for meats and vegetables.
For those on medication or with underlying health issues, a conversation with a doctor or pharmacist is essential before incorporating any new herbal remedy, even one as seemingly benign as anise.

Conclusion: Is anise bad for high blood pressure?
In conclusion, the claim that anise is bad for high blood pressure is based on a common and dangerous misconception, confusing it with true licorice root. In reality, moderate consumption of anise seeds is generally safe for people with hypertension and may even provide modest cardiovascular benefits through its antioxidant and anti-inflammatory properties. However, the use of concentrated anise oils or supplements should be approached with caution due to potential drug interactions and side effects. For the average person enjoying anise as a flavoring, there is no need for concern, but those on medication should always consult a healthcare provider to be safe.
