A 2018 report by the World Health Organization suggested that CBD may help treat symptoms relating to conditions such as cancer, Parkinson’s disease, multiple sclerosis (MS), anxiety, depression, insomnia and Alzheimer’s disease.
Inflammation is part of the process that leads to many diseases, including coronary heart disease, high blood pressure and stroke, and there is some evidence that CBD has anti-inflammatory properties. Other studies have suggested that CBD can have a protective effect on the heart: this has been proven in rats after a heart attack and in mice with some of the heart damage associated with diabetes. But because these studies are often based on findings in a lab or in animals, not in humans, we cannot yet be confident that CBD will benefit the human heart.
What CBD products are available?
Professor Sumnall argues that while it could be effective for some people, in some of these cases the results could be caused by the placebo effect (where the patient’s belief in a treatment makes them feel better). The placebo effect can be powerful, but Professor Sumnall warns that if people try CBD oil instead of speaking to their doctor, it could cause a problem.
CBD, or cannabidiol, is a chemical that’s extracted from the leaves and flowers of the cannabis plant. Cannabis itself is an illegal class B drug, as is the compound THC (tetrahydrocannabinol) which it contains. But pure CBD isn’t illegal, as it doesn’t cause the intoxicating effects of cannabis.
“In terms of the products found in shops, there’s virtually no evidence to support the claims made for a lot of them.” Harry Sumnall, Professor in Substance Use at Liverpool John Moores University
Meanwhile, in the previously-mentioned study of nine healthy volunteers, blood pressure was effectively lowered with a single dose of 600 mg.
When you visit the doctor, you’ll usually hear your blood pressure described by two numbers, like 120/70.
While Park told us that high blood pressure can be caused by a number of factors, CBD oil appears to lower increases in blood pressure caused by stress and anxiety.
What’s The Best CBD Dosage for High Blood Pressure?
According to the National Institutes of Health (NIH), acute pain can lead to high blood pressure. Because CBD acts on the pain receptors in the brain, the pain-relieving properties of CBD could lead to decreased blood pressure.
According to federal law, hemp-derived CBD oil is classified as having less than 0.3% THC, making it legal to purchase and use. And since hemp has minuscule amounts of THC content, CBD oil from this type of cannabis plant does not cause any of THC’s intoxicating side effects. Marijuana-derived CBD oil, whether it’s derived from sativa or indica-dominant plants, contains more than 0.3% THC as its primary active ingredient, and may make you high. It is only legal in states with recreational or medical marijuana legalization.
Called a “vasorelaxant” by researchers, CBD oil’s anti-inflammatory properties may lower blood pressure by allowing the free flow of blood through your heart, arteries and veins.
Many of the cannabidiol products you’ll see in CBD stores or online are of lower quality, since – as with any product – it’s more expensive to produce high-end merchandise and it sells for a higher price, often with lower profit margins for the vendors.
