CBD oil can interact with certain medications, including some drugs used to treat epilepsy. CBD inhibits an enzyme called cytochrome P450 (CYP450), which metabolizes certain drugs. By interfering with CYP450, CBD may either increase the toxicity or decrease the effectiveness of these drugs.

The findings suggest that CBD oil may be a suitable complementary therapy for people whose hypertension is complicated by stress and anxiety. However, there is no evidence that CBD oil can treat hypertension on its own or prevent hypertension in people at risk. While stress is known to complicate high blood pressure, it cannot cause hypertension.

CBD oil comes as full-spectrum oils or in forms that contain CBD isolates. Unlike isolates, which contain CBD only, full-spectrum oils contain a variety of compounds found naturally in the cannabis plant, including proteins, flavonoids, terpenes, and chlorophyll. Alternative practitioners believe these compounds offer more substantial health benefits, although there is no clear evidence of this.

Interactions

To determine an exact dose of CBD, remember that each drop of oil equals 0.05 mL of fluid. This means that a 30-mL bottle of CBD oil will have roughly 600 drops. If the concentration of the tincture is 1,500 mg/mL, one drop would contain 2.5 mg of CBD (1,500 mg ÷ 600 drops = 2.5 mg).

CBD’s exact mechanism of action is unclear. Unlike THC, CBD has a relatively low affinity for cannabinoid receptors in the brain. These are the molecules to which THC binds to elicit its psychoactive effects.

Proponents claim that CBD oil can treat a wide variety of health problems, including:

Human studies evaluating the use of CBD in treating chronic pain are lacking. Those that do exist almost invariably include THC, making it difficult to isolate CBD’s distinct effects.

CBD is metabolized in the liver — along with just about every other medication or supplement we consume. If there’s already a problem with the liver, it will be difficult to metabolize CBD effectively, causing CBD levels (and other medications) to remain elevated for extended periods.

For topicals, apply a small amount to the skin and wait for about 30 – 45 minutes to see if any rash or irritation appears. If not, you’re probably safe to apply the topical to a larger area of the body.

Who Should Avoid Using CBD?

This is true for both the positive and negative effects of CBD. Several of the research papers cited above used large doses of CBD (up to 20 mg/kg), which is significantly higher than the standard dose of CBD. However, despite remaining safe at these doses, the larger the dosage of CBD, the more chances there will be side effects.

CBD isn’t the only cannabinoid in the cannabis plant. There are over one hundred other cannabinoids also produced in the plant — many of which end up in your CBD oil. This is especially the case for full-spectrum hemp extracts.

If you experience any loss of consciousness or feel excessive lightheadedness, stop using CBD immediately and set up a visit with your doctor to discuss your symptoms.
