Your Cytochrome P450 enzyme system (or CYP450 system for short) is a system in the liver that is responsible for metabolizing potentially toxic compounds- including alcohol and over 60% of all drugs/medications you’ve eaten in your lifetime.
When CBD is present in the system, it can inhibit the system’s ability to metabolize certain drugs, leading to an increase in processing times. This is potentially dangerous because when the system is impacted this way, it may lead to higher/lower levels of those drugs or medications in your system- potentially causing unwanted side-effects.
Other things that impact the system in the same manor are: grapefruit, goldenseal, watercress, and St. John’s Wort- to name a few.
Please consult with your doctor before adding CBD to your routine, especially if you’re on any prescription medications. Discuss how to make adjustments to the dosage of your medication, so you can safely ingest both products.
