Cannabis oil preparations have been used in medicine for millennia, but the concern over the dangers of abuse led to the banning of medicinal marijuana or cannabis in the 1930s. CBD is the major non-euphorigenic component of Cannabis sativa. Some research is beginning to show that CBD is different than other well-studied cannabinoids. All cannabinoids function as ligands, meaning they dock onto the binding site of a protein and have the ability to modulate a receptor’s behavior. CB1 receptors are widely distributed, but are particularly abundant in areas of the brain, including those concerned with movement, coordination, sensory perception, emotion, memory, cognition, autonomic and endocrine functions. It appears that CBD oil has few adverse side effects when it’s used in appropriate amounts. The most common CBD oil side effects include drowsiness, dizziness, diarrhea, nausea, vomiting, dry mouth, anxiety and changes in mood. Pain relief: Both cancer and its treatment can lead to pain. Cancer often causes pain due to inflammation, pressure on internal organs, or nerve injury. When the pain is severe, it can even become resistant to opioids, which are powerful pain relievers. CBD indirectly acts on the CB2 receptors, which may help with widespread pain relief by reducing inflammation.
