High blood pressure is now a civilization disease. Narrowing and clogging of blood vessels leads to cardiovascular diseases. Can CBD help with prevention or treatment of hypertension?

Hypertension: Causes, Symptoms, and Treatment

Hypertension is becoming increasingly common. It no longer affects only older generations. More and more young people suffer from high blood pressure. The problem can be hereditary, but also the lifestyle that is currently full of rush and stress. These conditions are a breeding ground for hypertension.

High blood pressure not only leads to heart diseases and breathing problems. It can also lead to stroke or kidney damage.

The most common symptoms of hypertension include:

headaches
red faces
nosebleeds
shortness of breath
dizziness
heat and feeling faint

One of the common symptoms of hypertension are severe headaches or migraines

CBD Oil in the Fight Against High Blood Pressure

Meta-analysis published in Frontiers in Pharmacology shows that CBD could be a potential supportive drug for cardiovascular diseases, including hypertension and stroke. Why? Here are the reasons:

1. CBD is an Effective Vasodilator

University of Nottingham Royal Derby Hospital conducted a study in 2015 that proves CBD could be an effective vasodilator. This means it would be an excellent tool for dilating blood vessels and thus increasing blood flow. These findings were confirmed in a large study conducted by doctors and scientists from the United Kingdom. However, it is important to note that only healthy volunteers participated in this study, not people suffering from hypertension.

CBD can improve blood flow through the circulatory system.

2. CBD Helps Reduce Anxiety

Anxiety and lack of sleep are the most common factors associated with high blood pressure. According to available studies, CBD is capable of helping to reduce anxiety states and has a significant impact on post-traumatic stress disorder (PTSD).

3. CBD Helps Regulate Cortisol Levels

Cortisol is often called the "stress hormone" because the body releases it only when under pressure. Chronically high cortisol levels can lead to a reaction that increases blood pressure. As early as 1993, Brazilian scientists proposed using CBD to regulate cortisol secretion to reduce the amount of stress the body is exposed to and thus reduce the risk of hypertension.

4. CBD Has a Strong Anti-Inflammatory Effect

It is already known that CBD is a substance with anti-inflammatory effects. Inflammation can be one of the reasons for high blood pressure. By eliminating inflammation, this risk is also reduced. In addition to the aforementioned effects of using CBD, there are a few more things to mention. CBD is very well tolerated by the human body, even at a daily dose of 1500 mg.

Choose CBD or Conventional Medicine?

The most commonly prescribed medications to lower blood pressure are:

ACE inhibitors
Angiotensin II receptor blockers
Diuretics

However, these drugs cause side effects such as diarrhea, nausea, vomiting, shortness of breath, dry cough, anxiety, or exhaustion.

On the other hand, CBD oil has very few side effects. These include dry mouth and dizziness. However, this is only in the case of consuming a really large amount. Nausea is more likely caused by the carrier oil than CBD.

Commonly used medications for treating hypertension can cause side effects. Consult with a doctor about the possibility of using CBD.

Each of us reacts differently to CBD oil, so dosage needs to be adjusted. The best solution is to start with low doses. Try the CBD calculator.

CBD oil certainly has its place in the treatment of hypertension. However, don't forget to consult with your doctor.
