10 Spices And Herbs That May Help Lower High Blood Pressure (2024)

Managing high blood pressure usually requires a mix of medications and a healthy diet. Certain natural ways to lower blood pressure, such as eating garlic, basil, and other herbs and spices, may also work.

High blood pressure, also called hypertension, can often be managed with medication, as well as dietary and lifestyle changes. Some herbs and spices may also help lower blood pressure.

Below are 10 herbs and spices that may help lower blood pressure. Make sure to speak with your doctor before using any of the following herbs.

1. Cinnamon

Cinnamon (Cinnamomum verum) has been used for centuries in traditional medicine to treat heart conditions, including high blood pressure.

While it’s not fully understood how cinnamon lowers blood pressure, animal research suggests it can help dilate and relax the blood vessels.

A review of nine studies of 641 participants showed that taking cinnamon reduced systolic and diastolic blood pressure by an average of 6.2 mm Hg and 3.9 mm Hg, respectively. This effect was stronger when people took cinnamon consistently over 12 weeks.

Cinnamon is easy to incorporate into meals. Concentrated cinnamon supplements are another option.

Summary

Cinnamon appears to help dilate and relax the blood vessels, which may help lower blood pressure.

2. Celery seeds

Celery seeds (Apium graveolens) are packed with various nutrients, such as:

  • iron
  • magnesium
  • manganese
  • calcium
  • fiber

Some research suggests celery seeds may help lower blood pressure.

One small study of 52 participants examined the effects of celery seed extract on blood pressure. During the 4-week study, half of the participants were given 1.34 grams of celery seed extract a day, and the other half were given placebo capsules.

Researchers noted a decrease in systolic and diastolic blood pressure in the celery group. No changes were observed in the placebo group.

Researchers have also suggested that compounds in celery seed extract may help lower blood pressure by acting as a natural calcium channel blocker.

In addition, celery seed is also a source of dietary fiber, which has been linked to lower blood pressure.

Despite some promising results, research is limited on the effects of celery seed on blood pressure. Scientists need to conduct more human research in this area.

Summary

Some research suggests celery seeds may reduce blood pressure. This spice may be effective thanks to its fiber and action as a natural calcium channel blocker.

3. Cardamom

Cardamom (Elettaria cardamomum) is packed with antioxidants that may help lower blood pressure and treat other symptoms of metabolic syndrome.

It may also have positive effects on:

  • obesity
  • triglyceride levels
  • cholesterol levels
  • insulin sensitivity

Cardamom is simple to incorporate into your cooking or baking. Alternatively, you could take a cardamom supplement or extract under the guidance of your doctor.

Summary

Research suggests cardamom may help lower blood pressure and have other positive effects on obestiy, triglyceride levels, cholestrol levels, and insulin sensitivity.

4. Garlic

Garlic (Allium sativum) is rich in allicin, a compound that may benefit your heart and have protective effects.

A review of 12 studies in over 550 people with high blood pressure found that taking garlic reduced systolic and diastolic blood pressure by an average of 8.3 mm Hg and 5.5 mm Hg, respectively.

This reduction was similar to the effects of blood pressure medications.

Summary

Garlic contains allicin and has been shown to help relax blood vessels and aid blood flow. Collectively, these factors may help reduce blood pressure.

5. Basil

Basil (Ocimum basilicum) is popular in alternative medicine because it’s rich in powerful compounds.

Animal studies suggest basil may help reduce blood pressure. In 2023, a study on rats with hypertension fed them antihypertensive compounds found in green basil leaves. The results found that the plant compounds had a positive effect on the rats’ blood pressure.

More research is needed to investigate whether basil helps lower blood pressure in humans.

Basil is easy to add to a variety of meals, including scrambled eggs, salads, sauces, and more. It can also be grown as a potted plant indoors.

Summary

Basil contains compounds that may help reduce blood pressure, according to animal studies. However, more human research is needed.

6. Parsley

Parsley (Petroselinum crispum) contains a variety of compounds, such as vitamin C and dietary carotenoids, that may reduce blood pressure.

In a review of 19 randomized controlled trials, researchers found that carotenoid supplementation is associated with lower systolic and diastolic blood pressure. Benefits were seen in adults who consumed 0 to 25 mg and 0 to 20 mg of carotenoids per day.

Animal studies have shown that parsley reduces both systolic and diastolic blood pressure by acting like a calcium channel blocker, a type of medication that helps relax and dilate blood vessels.

However, limited human research exists on parsley and blood pressure. More research is needed to better understand its effects.

Summary

Parsley contains a variety of compounds, such as dietary carotenoids, that may help lower blood pressure.

7. Thyme

Thyme (Thymus vulgaris) is packed with numerous healthy compounds, including Rosmarinic acid.

Results from an animal study have shown that taking rosmarinic acid helps reduce systolic blood pressure blood pressure. It inhibits angiotensin-converting enzyme (ACE), a molecule that narrows blood vessels and raises blood pressure, so inhibiting ACE may lower blood pressure.

There’s limited human research on thyme and blood pressure. Scientists need to do more research to investigate these effects in humans.

Summary

Thyme contains powerful compounds, such as rosmarinic acid, that appear to help relax blood vessels in animal studies.

8. Ginger

Ginger (Zingiber officinale) is a staple in alternative medicine. For centuries, people have used it to improve many aspects of heart health, including:

  • circulation
  • cholesterol levels
  • blood pressure

Ginger may reduce blood pressure. A review found that along with hypotensive (blood pressure-loweirng) properties, ginger may also be:

  • anti-ulcer and anticholinergic
  • anti-inflammatory
  • anti-nausea
  • blood ciruclation-enhancing
  • antimicrobial

Ginger is flavorful and easy to incorporate into your diet with meals. Alternatively, you can purchase ginger supplements online. These are more concentrated.

Summary

Ginger may help lower blood pressure and provide many other protective effects.

9. Chinese cat’s claw

Chinese cat’s claw differs from cat’s claw (Uncaria tomentosa). Despite its similar name and appearance, cat’s claw plant has a different origin and different chemical properties.

Chinese cat’s claw contains several compounds, such as hirsutine and rhynchophylline, that may stimulate blood vessels to produce nitric oxide (NO) and have anti-hypertensive properties. NO is a chemical compound that helps blood vessels relax and dilate.

Taking Chinese cat’s claw extract or its compounds may help reduce blood pressure and aid blood flow. However, human studies are still limited.

You can purchase Chinese cat’s claw at select health food stores or online.

Summary

Chinese cat’s claw contains the compounds hirsutine and rhynchophylline that may help blood vessels relax.

10. Bacopa monnieri

Bacopa monnieri is used in Ayurvedic medicine use it to treat various conditions, including:

  • depression
  • memory loss
  • high blood pressure

In animal studies, Bacopa monnieri helped stimulate blood vessel dilation and release of NO.

Although the findings from animal studies are promising, the effects of Bacopa monnieri on blood pressure in humans are still unclear. Scientists need to do more research on this herb’s effects.

You can buy Bacopa monnieri from health food stores and online. It’s available in several forms, including powder and capsules.
