Harmful Herbs for Individuals with Heart Issues
It is essential to recognize that numerous natural herbs currently in use have not undergone rigorous scientific scrutiny. In fact, some may lead to significant adverse health effects in general and specifically impact heart health. Furthermore, these herbs can interact negatively with various medications one might be taking. Therefore, it is crucial to consult with a healthcare professional before using any of these herbs, particularly for individuals with existing heart conditions.
While many herbs may offer several health benefits, excessive consumption or use by individuals with specific health conditions may be detrimental to heart health. Below, we outline some of these herbs and their potential side effects on cardiac well-being:
Marjoram
High doses of Marjoram (Marjoram, also known as Majoram or Sweet Marjoram) can result in a decreased heart rate, especially in individuals experiencing bradycardia.
Ginger
Excessive intake of ginger may exacerbate certain heart diseases. A publication in PLOS One in 2015 indicated that a single dose of 10 grams of ginger could inhibit blood clotting in patients with heart issues, while a smaller dosage of around 4 grams lacked this effect.
Yerba Mate
The caffeine in Yerba Mate can contribute to irregular heart rhythms, high blood pressure, an increased risk of miscarriage, or elevated blood lipids when consumed by some individuals with heart disease or hypertension. Given its stimulant effects, it is vital to consult a healthcare provider before using this herb in the presence of heart issues.
Blue Cohosh
Consumption of Blue Cohosh may worsen certain heart disorders, provoking angina pain and hypertension. This herb might cause vasoconstriction of the coronary arteries, leading to reduced oxygen flow to the heart, making it advisable to avoid this herb if a heart issue is present.
Arnica
Overuse of Arnica can trigger transient increases in blood pressure and rapid heartbeats, particularly in individuals with pre-existing heart rhythm problems. Consequently, those experiencing tachycardia should refrain from using this herb without medical approval.
Licorice Root
Recommendations indicate that individuals over 40 with heart disease or hypertension should be cautious with licorice, as more than 57 grams daily for two weeks can cause severe health issues. This herb may lead to:
- Water retention, worsening congestive heart failure.
- Increased risk of arrhythmias.
Green Tea
Green tea contains a significant amount of caffeine, similar to Yerba Mate; excessive consumption over an extended period may disrupt heart rhythms in individuals with heart disease. Moreover, hypertensive patients may find their blood pressure elevated by drinking green tea, though tolerance may develop with regular consumption.
Herbs Detrimental to General Heart Health
Yohimbe
High doses of Yohimbe may pose serious health risks, including heart issues, significantly low blood pressure, or shortness of breath. It is not safe for everyone to take Yohimbe orally, as it may result in severe side effects like tachycardia, arrhythmias, heart attacks, or hypertension. Numerous studies have documented the risks associated with Yohimbe supplements, leading to its prohibition in several countries.
Ephedra
Consumption of Ephedra can stimulate heart muscles, which may worsen arrhythmia. It is particularly crucial for individuals with the following conditions to avoid this herb:
- Heart disease.
- Hypertension.
- Cardiac rhythm disorders.
Ginseng
When first using Ginseng, an individual may experience slight alterations in heart rhythm and blood pressure; however, this effect usually dissipates after the first use. Caution is advised when using this herb in persons with heart disease, as adequate studies regarding its impact on such individuals are lacking.
Tips for Maintaining Heart Health
Individuals can enhance their well-being and protect their hearts by adopting a healthy lifestyle. Here are several tips to help maintain heart health:
- Increase the intake of fruits and vegetables to lower the risk of heart disease and improve overall health.
- Incorporate whole grains into your diet for their rich nutrient content, including fiber, B vitamins, vitamin E, and healthy fats.
- Include healthy fats in your diet, focusing on monounsaturated (e.g., avocados, nuts) and polyunsaturated fats (e.g., omega-3 and omega-6 fatty acids found in fish and sunflower seeds).
- Avoid excessive weight gain, which poses various health risks and places additional strain on arterial walls, causing the heart to work harder and increasing the likelihood of diseases such as atherosclerosis, hypertension, and stroke.
- Limit food portion sizes to prevent unhealthy weight gain and reduce the risk of heart disease.
- Reduce salt intake to maintain healthy blood pressure levels. It’s advisable to minimize added salt during cooking and avoid excessively salty processed foods.
- Quit smoking, as it is one of the primary causes of coronary artery disease.
- Engage in moderate aerobic exercise for at least 150 minutes weekly to lower the risk of heart disease while also improving mood and reducing stress.
Summary
Certain natural herbs can trigger cardiac symptoms in those suffering from heart conditions, including Marjoram, Yerba Mate, Blue Cohosh, Licorice Root, and Arnica. Additionally, some herbs may negatively affect heart health even in healthy individuals, such as Ginseng, Ephedra, and Yohimbe. Thus, consulting a healthcare professional before taking any of these specific herbs or any other herbal products for therapeutic purposes is vital.
