WHAT: CBD Oil is most often administered by the sublingual method, which simply means "under the tongue".
HOW: Place the recommended dosage of CBD oil beneath your tongue and hold the oil there for 10-20 seconds before swallowing.
WHY: Beneath your tongue is the mucous membrane which is packed full of tiny capillaries that work rapidly to diffuse medicine into the bloodstream. In contrast, substances absorbed in the intestines (if you just swallowed the oil) are subject to "first-pass metabolism" in the liver before entering the general circulation, which can degrade the efficacy.
Many drugs are designed for sublingual administration, including cardiovascular drugs, steroids, barbiturates, benzodiazepines, opioid analgesics, enzymes and, increasingly, vitamins and minerals.
