The study suggests CBD oil may be a good complementary therapy for people whose high blood pressure is affected by stress and anxiety.
The way that CBD acts in the brain can explain why this happens. In low doses, CBD may act the same as surrounding molecules that normally bind to the receptor, which "turns up" their signaling.
Most oils come in 30-milliliter (mL) bottles with a dropper cap.
Possible Side Effects
The study authors report that CBD had powerful anxiety-relieving effects in animal research. But the results weren't what you'd expect.
Scientists believe CBD reduces nerve pain by binding to receptors in the brain that control the speed at which nerve signals pass between nerve cells.
Many of these interactions are mild and don't demand a change to treatment. Others may require you to substitute the drugs you are taking or to separate doses by several hours.
A 2017 study reported that only 31% of CBD products sold online were correctly labeled. Most contained less CBD than advertised, while 21% had significant amounts of THC.
Observational studies and randomized controlled trials (RCTs) of the effectiveness of cannabinoids in chronic noncancer pain found a 30% reduction in pain in 1 out of 3 of those using cannabinoids. This was considered significant.
Two ways to use CBD are by mouth (oral) and applied to the skin (topical).
CAUTION: Since CBD may cause tiredness or drowsiness, people should be very careful when driving, using tools or other equipment, or performing other risky activities.
CBD, Foods and Herbs
A review and meta-analysis of 8 studies with low-quality evidence of cannabis-based medicines found that they were better at reducing sleep problems compared to inactive medicines (placebo).
CBD should be used according to the manufacturer’s instructions. A person should read and follow the label carefully. Use no more than instructed. Using more may increase the chance of side effects or it may cause other problems.
Early research on CBD for the treatment of insomnia suggests that it may be effective. Additional studies are needed.
Types of CBD
Topical cannabidiol oil was studied in 29 people with lower limb peripheral neuropathy. After using the oil for 4 weeks, the people had less intense and sharp pain and fewer other uncomfortable sensations.
The body also produces natural cannabinoids, called endocannabinoids. Cannabinoids act on cannabinoid receptors.
