Herbs to Help Normalize High Blood Pressure
High blood pressure or hypertension is often discussed at doctor’s visits and frequently triggers a prescription. These are the most common conditions. National Heart, Lung, and Blood Institute Half of Americans are unaware, warns the report. High blood pressureSome people don’t even know it.
Blood pressure fluctuates throughout the day. It is important to remember that blood pressure can cause other health problems, so it should be monitored regularly.
There are two numbers that you will hear when we measure blood pressure. The first number you will hear is the systolic blood pressure. This is when blood is being pushed through the vessels by our heart. The systolic pressure should be kept at 120. The second number refers to diastolic pressure. This is the pause in between heartbeats as the heart fills up with blood. The diastolic blood pressure should be at least 80.
These numbers are as follows The Mayo Clinic This is explained in units of millimeters or mm Hg. Our blood pressure readings are usually 120/80 mmHg. Don’t worry about the units, the numbers are what matters.
We can check our blood pressure at the pharmacy if they have a digital blood pressure measurement machine or at the doctor’s office with a blood pressure cuff. A home blood pressure monitor can be used to check your blood pressure. The blood pressure fluctuates throughout the day. When we monitor our blood pressure, it’s important to be consistent.
You should take your blood pressure in the same place, at the same time and in the exact same condition. You should wait at least 30 minutes after drinking, eating, smoking, and exercising before you take a blood pressure reading.
Your blood pressure can be affected by even watching the news or having stressful thoughts. In fact, so many people experience stress or discomfort when they go to the doctor’s office that it has led to a phenomenon called “white coat hypertension.” This refers to blood pressure readings that are higher at the doctor’s office than in other settings.
High blood pressure can be caused by a combination of factors such as exercise, healthy eating habits, not smoking and managing stress. Vessels that are under too much pressure for long periods lose their elasticity and don’t work as well. High blood pressure can be reduced by keeping your blood pressure under control. It helps keep your heart and vessels healthy under normal pressures to prevent stroke, kidney disease, and cardiovascular disease.
Lifestyle changes can be made to help maintain normal blood pressure and prevent hypertension. These include lifestyle changes such as a change in diet, exercise, and stress levels. These are essential to protect against high blood pressure damage. However, there are some beneficial herbs that we can include in our diet. Some herbs may have similar healing properties to high blood pressure medications.
Low blood pressure can be reduced by using safe and small amounts of these herbs. These herbs can also help reduce the likelihood of long-term high bloodpressure. The potential for a high blood-pressure diagnosis can be reduced by using herbs, along with other measures to manage blood pressure.
Some herbs may not be compatible. If you take medication, make sure to follow the instructions of your healthcare provider.
Blood Pressure Medications
There are many medications that can help with high blood pressure. Some herbs can mimic the effects of some medications. You could even say that such medicines were created from the actions of traditional, folk and ancient medicines. Many natural substances, including plants, were known to have medicinal properties.
Diuretics are a type of medication that helps the body get rid of excess water and sodium. They also increase urination. These drugs are sometimes called water pills. They can be prescribed for patients suffering from hypertension. Natural diuretics can be found in many foods and herbs, including parsley, celery, cucumbers, watermelon and lemons as well as garlic and ginger and onions.
A research study published by Pharmacy and Therapeutics in 2014 found that the following results were consistent with previous studies. Hypertension: Is It Time to Replace Drugs With Nutrition and Nutraceuticals?, researchers discussed the part nutrition plays in conventional medication therapy for high blood pressure.
When exploring natural compounds, they stated, “Many natural compounds in food, as well as certain nutraceutical supplements, vitamins, antioxidants, or minerals, can mimic drugs, functioning similarly to a specific class of antihypertensive medications (Table 1). However, they may be less potent and take longer to work than the antihypertensive drug. When used in combination with other nutrients and nutraceutical supplements, though, the antihypertensive effect can be magnified.”
Plant-Based Medicines to Treat High Blood Pressure
- Thyme (Thymus vulgaris)
A common herb that is fragrant and flavorful, culinary thyme is delicious in soups, baked goods, marinades, and stuffing. It is lovely added to grilled and roasted meats and fresh, cooked, and roasted vegetables. Thyme is found at the store as dried leaves, fresh herbs, or in a variety of herb blends.
Thyme originates from the Mediterranean and has over fifty varieties, usually hardy, evergreen, woody perennials. It is drought tolerant, slow growing, and loves well-draining average soils. It doesn’t like to have wet roots and grows better in warm sunny weather.
Thyme is loved by bees and the low-growing herbs have flower spikes in mid-summer. To harvest thyme, prune new growth from stems, about 4 to 6 inches. The best time to harvest thyme is before flowering in late spring, usually, in the late morning after the morning dew has dried. Use thyme fresh within a few days of harvest. Thyme also freezes and dries well for future use.
Thyme Constituents and Healing Activity
Thyme has a bounty of medicinal actions including anti-inflammatory, antimicrobial, antioxidant, and anticancer effects. It has many phytonutrients, minerals, and vitamins as well as flavonoids and essential oils including thymol and carvacrol. There are eight phenolic acids in thyme including gallic acid, syringic acid, and rosmarinic acid. Rosmarinic acid is one of the main constituents of thyme and is known for many medicinal actions including treating high blood pressure. This study from 2017, showed rosmarinic acid reduced blood pressure in animal studies by acting as an angiotensin-converting enzyme (ACE) inhibitor. Other studies have shown that extracts of thyme contain rosmarinic acid. The extracts significantly decrease systolic and diastolic blood pressure in animal studies.
How to Use Thyme
Thyme for tea? Thyme’s antioxidant and antimicrobial activities are not only great for colds and respiratory health, but they may help maintain normal blood pressure as well. Fresh sprigs or dried or frozen thyme leaves are simply steeped in boiling water and strained for a pungent, fragrant cup of slightly medicinally flavored tea.
Add thyme more often to dishes and look for recipes that inspire more thyme in the diet. Roasted potatoes or other roasted vegetables sprinkled with fresh, dried, or frozen thyme are extraordinary. Explore thyme in baked goods such as an onion thyme tart or lemon garlic thyme focaccia for delicious ways to use thyme.
Thyme supplements are available. Follow supplement directions. If you are already taking medications including ones to lower blood pressure, be sure to check with health care providers and supplement instructions for potential negative interactions.
- Parsley (Petroselinum crispum)
Relegated to garnish status, the vibrant green, pretty, curled leaves of parsley do more than add contrast to a dinner plate. For those who do eat the garnish, you’ll know parsley helps to cleanse the palate and freshen the breath. But parsley has so much more to offer! This biennial plant packs nutrition and flavor in its abundant curled or flat leaves. The clean refreshing flavor, while undoubtedly pretty, has health benefits galore when added to salads, soups, sauces, marinades, as well as egg, and meat dishes.
Yet another Mediterranean herb, parsley likes a rich soil with lots of organic matter and a full sun location. Parsley grows easily from seed, sprouting in 10 to 14 days. It is a biennial, meaning it puts on a lot of delicious green growth in its first year. In the second year, parsley leaves are tougher and less flavorful because the plant is putting its energy into making seeds. Tall central stalks are topped with yellow flower clusters that develop into striped seeds in mid to late summer.
Seeds can be dispersed throughout the garden where there is adequate soil and moisture. Do this a couple of years in a row, and fresh first-year parsley plants will emerge for harvest fairly reliably.
Parsley leaves can be curled or flat, depending on the variety. The robust leaves will last in the fridge for several days. They dry nicely for future use. They also freeze well. Harvest leaves from first-year plants early in the day from late spring through to late fall. Plunge leaves in cold salted water to remove any little visitors such as aphids. Use fresh or hang to dry in a dark location or a paper bag. Large clean bunches of fresh parsley can be pulverized in a food processor and packed loosely in containers or jars in the freezer. The frozen pulverized leaves can be scooped into soups, sauces, salads, and marinades at any time throughout the year.
Parsley is available fresh and dried from grocery stores. When parsley is in season, you can acquire a large amount and store it as described above. Parsley is also available as a supplement to use as a natural diuretic, for heart health, to aid digestion, and for its high nutrient and antioxidant qualities.
Parsley Constituents and Healing Activity
A large study of available research, from 1966 to 2013, that related to the ethnomedicinal uses, phytochemistry, and pharmacological activities of parsley, found this medicinal plant had a wide range of proven medicinal activity. Some of these actions were parsley’s antioxidant, brain-protective, anti-diabetic, analgesic, gastroprotective, antibacterial, and antifungal activities. In addition, parsley showed diuretic and hypotensive actions which had evidence of helping high blood pressure as well as cardiac disease.
A study from 2019 aimed to evaluate the antihypertensive activity of the aqueous extract of the parsley plant. While the study was an animal study, it did show the extract decreased systolic, diastolic, and mean arterial blood pressure. It concluded that “The study illustrates the beneficial action of P. crispum as an antihypertensive agent.”
How to Use Parsley
Add parsley to almost any meal. Whether sprinkled on top, incorporated into soups and sauces, or used as a complimentary garnish, parsley’s refreshing flavor has many health benefits and may help to maintain normal blood pressure. Try chimichurri, a marinade loaded with fresh parsley, or tabbouleh salad, which is packed with the bright flavors of parsley and lemon.
- Corn Silk (Stigma maydis)
The delightful shucking of fresh corn comes with the finicky task of removing the long silky threads that grow just underneath the husks. Interestingly, there is one thread-like strand for each kernel of corn, and each strand, known as a stigma, pollinates each kernel.
Corn silk is often just headed for the compost bin. But, Traditional Chinese Medicine, as well as Native American medicine and others use corn silk as an herbal remedy. Traditional uses aided mental health, urinary tract infections, and heart disease.
The long threads are easy to collect when shucking corn cobs. It is best to use organic or homegrown corn. You can dry corn silk in a paper bag or on a tray, at room temperature, away from light. Collect strands, roll them into 1-to-2-inch nests like miniature pasta nests, and place them on a tray. Allow drying for 48 to 72 hours. Each corn silk nest is perfect for one cup of corn silk tea.
With corn season at its end in many places, corn silk is also available in dried form or as a supplement.
Corn Silk Constituents and Healing Activity
Corn silk has bioactive constituents such as flavonoids and terpenoids which have diuretic, antioxidant, and anti-hypertensive activity. A chemical made by the body called angiotensin-converting enzyme (ACE) plays an important role in maintaining blood pressure. Sometimes it works too well and can raise blood pressure by narrowing blood vessels. Inhibiting ACE is a common treatment for high blood pressure. Sometimes people with hypertension are prescribed ACE inhibitors to relax blood vessels to lower blood pressure. Corn silk tea has shown effects on ACE activity. A water extract of corn silk, in this animal study, significantly reduced systolic blood pressure levels and inhibited ACE activity.
How to Use Corn Silk
Tea or supplement are the common ways to use corn silk. To make corn silk tea, use a teaspoon of dried corn silk to one cup of boiling water. Allow to steep for 5 to 10 minutes. Enjoy with a little lemon and honey or the flavoring of your choice.
Corn silk is nontoxic and this Korean study shows very high doses did not cause mortality or abnormal findings in animal subjects. Daily doses of corn silk are likely safe for most people. Start with a low dose to observe how your body reacts and check for any negative effects such as allergic reactions.
Blood Pressure Maintenance Bedtime Tea
While never a recommendation to replace doctor-prescribed or recommended medications, this tea, in conjunction with lifestyle changes, may help maintain normal blood pressure.
A study published in 2019, noted blood pressure medication taken at bedtime was more effective. For this reason, this is a tea for bedtime, although it could be taken at any time throughout the day.
Ingredients:
¼ teaspoon dried thyme leaves or ½ teaspoon fresh thyme leaves
¼ teaspoon dried parsley leaves or ½ teaspoon fresh parsley leaves
¼ teaspoon dried corn silk or ½ teaspoon fresh corn silk
1 to 2 cups of high-quality boiling water.
Place ingredients in a tea ball or loose in a large cup. Cover with boiling water. Allow to steep for 5 to 10 minutes. Remove the tea ball or strain the tea through a fine strainer. Flavor with lemon, honey, or flavoring of your choice, and enjoy.
For those who don’t like getting up to use the bathroom at night, take this tea two hours before bedtime.
Caution
Traditional plant-based medicines have been used for centuries and may be generally regarded as safe. However, it is true our world is not what it was centuries ago. Where plants grow, and how they are cultivated, harvested, and processed may change the chemical composition of their medicinal properties. Just like prescription and over-the-counter medicines, plant-based medicines may interact with other medicines, have unknown side effects, or relate to allergies, sensitivities, or medical conditions.
With any new ingredient, you can do a small skin test. Place a small amount of herb on the skin and wait 24 hours. Any reaction such as discomfort, itchiness, or hives may be an indication of sensitivity. Be aware of potential contraindications with medications. Always check with your healthcare provider before starting new herbal remedies. If, when taking a remedy, symptoms persist or worsen, discontinue the use of the plant-based remedy.
