Studies indicate that CBD may be able to help with high blood pressure. One recent study treated nine healthy men with one dose of 600 mg of CBD oil and found it reduced resting blood pressure, compared to a placebo. The same study also gave the men stress tests that normally increase blood pressure. Interestingly, the single dose of CBD led the men to experience a smaller blood pressure increase than normal in response to these tests.

Researchers have suggested that the stress- and anxiety-reducing properties of CBD are responsible for its ability to help lower blood pressure.

Additionally, several animal studies have demonstrated that CBD may help reduce the inflammation and cell death associated with heart disease due to its powerful antioxidant and stress-reducing properties. One study found that treatment with CBD reduced oxidative stress and prevented heart damage in diabetic mice with heart disease.
