3. Medical Applications of Royal Medic

Royal Medic is a CBD-dominant hybrid strain known for its therapeutic properties and low psychoactivity, making it a top choice for medical cannabis patients. With CBD levels ranging from 12-15% and moderate THC (10-12%), it provides anti-inflammatory, analgesic, neuroprotective, anxiolytic, and anti-seizure benefits without intense intoxication.


Pharmacological Mechanisms of Action

The medical benefits of Royal Medic stem from its high CBD content, moderate THC levels, and unique terpene profile. These compounds interact with the endocannabinoid system (ECS) and other physiological pathways.

Interaction with the Endocannabinoid System (ECS)
  • The ECS regulates pain, mood, inflammation, immune function, and neurological processes through CB1 and CB2 receptors.
  • CBD (Cannabidiol) has low affinity for CB1 receptors but modulates CB2 activity, reducing inflammation and pain sensitivity.
  • THC (Tetrahydrocannabinol) acts on CB1 receptors, providing mild analgesic effects.
  • Other cannabinoids (CBG, CBC, THCV) contribute to neuroprotection, anti-inflammatory effects, and appetite regulation.
Terpenes and Their Medical Contributions

The terpene profile enhances the strain’s medicinal value:

TerpeneMedical BenefitsMechanism of Action
MyrceneSedative, muscle relaxation, anti-inflammatoryEnhances GABAergic neurotransmission, acting as a natural muscle relaxant
LimoneneAntidepressant, anxiolytic, anti-inflammatoryBoosts serotonin and dopamine levels, reducing anxiety and depression
CaryophylleneAnti-inflammatory, analgesic, gut healthSelectively activates CB2 receptors, modulating pain and immune response
PineneNeuroprotective, anti-inflammatory, memory-enhancingInhibits acetylcholinesterase, improving cognitive function
LinaloolAnti-anxiety, sedative, pain reliefModulates glutamate and serotonin pathways, reducing anxiety and pain perception
