Purple OG Kush is a powerful indica-dominant hybrid known for its deep relaxation effects, distinct purple hues, and earthy, sweet flavor profile. It merges two iconic strains—Purple Kush and OG Kush—to produce a cultivar rich in cannabinoids and terpenes, ideal for both medical and recreational users. Purple OG Kush exemplifies the therapeutic potential of modern cannabis hybrids, with strong sedative properties, analgesic effects, and a uniquely calming high that appeals to a wide user base.
Genetic Lineage and Breeding
Purple OG Kush is bred from:
- Purple Kush: A pure indica originating from the Hindu Kush region and Afghani landraces, known for its sedative effects, purple coloration, and hashy flavor.
- OG Kush: A hybrid (possibly Chemdawg × Hindu Kush × Lemon Thai) revered for its high THC content and euphoric cerebral buzz.
Purple OG Kush fusion results in a plant with:
- Indica dominance: Typically 75–80% indica / 20–25% sativa
- THC range: 18% to 24%
- CBD content: Low (<1%), though some phenotypes may show trace levels
- CBN/CBC: Occasionally present in measurable quantities, contributing to its sedative effects
Cannabinoid Profile
Primary Cannabinoids
- THC (Δ9-tetrahydrocannabinol): 18–24%
- In Purple OG Kush mainly attaches itself to central nervous system CB1 receptors.
- Induces euphoria, analgesia, sedation, and appetite stimulation
- CBD (Cannabidiol): <1%
- Modulates THC’s psychoactivity
- Reduces inflammation and anxiety
- CBN (Cannabinol): <0.5%
- Mildly psychoactive and sedative; enhances sleep quality
- CBC (Cannabichromene): Trace
- Anti-inflammatory and mood-elevating

Medical Applications
Purple OG Kush is a THC-dominant, indica-leaning hybrid with a rich terpene profile (notably myrcene, linalool, limonene, and caryophyllene), making it highly effective for a broad range of physical and neuropsychiatric conditions. Though it contains low CBD, its effects are significantly shaped by entourage interactions between THC and non-cannabinoid phytochemicals.
Chronic Pain Management
Mechanism of Action
- THC binds to CB1 receptors in the central nervous system (CNS), modulating nociceptive transmission in the spinal cord and brain (especially in the periaqueductal gray and thalamus).
- Caryophyllene, a terpene that binds to CB2 receptors on immune cells and peripheral nerves, reduces inflammation and pain signaling.
- Myrcene in Purple OG Kush is believed to contribute to analgesia by enhancing THC transport across the blood-brain barrier and acting on opioid receptors.
Relevant Conditions
- Neuropathic pain (sciatica, diabetic neuropathy)
- Inflammatory pain (arthritis, IBD-related discomfort)
- Musculoskeletal and injury-related pain
Clinical Support
- Multiple human and animal studies have shown THC-rich cannabis reduces pain intensity by 30–50% in treatment-resistant patients.
- The National Academies of Sciences (2017) identified substantial evidence for cannabis’s efficacy in chronic pain.
Insomnia and Sleep Disorders
Mechanism of Action
- THC in Purple OG Kush reduces sleep latency (time to fall asleep) and increases slow-wave (deep) sleep via CB1-mediated suppression of arousal networks.
- Myrcene and linalool in Purple OG Kush have sedative and muscle-relaxant properties, likely mediated by GABAergic potentiation and interaction with adenosine receptors.
- CBN (cannabinol), present in trace amounts, enhances sleep quality through mild sedation.
Relevant Conditions
- Primary insomnia
- Secondary sleep disorders (e.g., anxiety-related or pain-induced)
- REM sleep behavior disorder, nightmares (esp. in PTSD)
Scientific Basis
- THC has been shown to reduce REM sleep duration, which may be beneficial in PTSD by reducing nightmares.
- Animal studies support myrcene’s sedative action, and linalool has demonstrated hypnotic effects in both rodents and humans.
Anxiety and Stress Disorders
Mechanism of Action
- Limonene modulates serotonin (5-HT1A) and dopaminergic pathways, producing an antidepressant-like and anxiolytic effect.
- Linalool affects GABA-A receptors, decreasing neuronal excitability, similar to the action of benzodiazepines.
- THC at low to moderate doses suppresses overactive amygdalar activity, reducing fear and stress responses.
Relevant Conditions
- Generalized Anxiety Disorder (GAD)
- Social Anxiety Disorder (SAD)
- Adjustment disorder with anxious features
- Subclinical chronic stress and burnout
Caution
- High-THC strains can worsen anxiety in sensitive individuals or at high doses due to dopaminergic overactivation in the prefrontal cortex.
Depression and Mood Dysregulation
Mechanism of Action
- THC increases dopamine release in the nucleus accumbens, producing mild euphoria and mood elevation.
- Limonene shows monoamine oxidase (MAO) inhibitory activity, increasing serotonin and dopamine levels.
- Caryophyllene has been shown in animal studies to exert antidepressant-like effects via CB2 receptors.
Relevant Conditions
- Mild to moderate depressive episodes
- Bipolar depression (adjunct use, not during mania)
- Seasonal Affective Disorder (SAD)
Clinical Insight
- While not a primary antidepressant, THC-dominant strains with mood-elevating terpenes may acutely improve affect, especially in treatment-resistant cases or where energy is low.
Appetite Stimulation and GI Disorders
Mechanism of Action
- THC activates CB1 receptors in the hypothalamus, stimulating ghrelin (hunger hormone) and enhancing olfactory sensitivity.
- Also slows gastric emptying, potentially aiding in nutrient absorption and reducing nausea.
Relevant Conditions
- Cachexia due to HIV/AIDS or cancer
- Anorexia nervosa (supportive use)
- Inflammatory Bowel Disease (IBD) with appetite suppression
Evidence
- FDA-approved Dronabinol (synthetic THC) is used clinically to treat wasting syndrome and nausea, indicating Purple OG Kush’s therapeutic potential in similar domains.
PTSD and Trauma-Related Conditions
Mechanism of Action
- THC dampens hyperactive limbic circuits, especially in the amygdala and hippocampus.
- Linalool and myrcene promote tranquility and reduce sympathetic overactivation.
- THC modulates memory reconsolidation, possibly decreasing the emotional charge of traumatic memories.
Benefits
- Reduced frequency/intensity of flashbacks
- Improved sleep, less hypervigilance
- Increased emotional regulation
Clinical Data
- Early-stage studies show cannabis can significantly reduce CAPS (Clinician-Administered PTSD Scale) scores and improve quality of life in combat veterans and trauma patients.
Muscle Spasms, Tremors, and Neurological Conditions
Mechanism of Action
- THC modulates motor pathways in the basal ganglia and cerebellum.
- GABAergic potentiation from linalool and myrcene decreases muscle excitability.
- CB2 activation by caryophyllene reduces neuroinflammation.
Relevant Conditions
- Multiple Sclerosis (MS) spasticity
- ALS-related tremors
- Parkinsonian rigidity (adjunctive)
- Certain seizure phenotypes (in low THC doses only)
Evidence
- Sativex (THC:CBD oral spray) is approved in several countries for MS-related spasticity, validating similar effects in strains like Purple OG Kush.
Headaches and Migraines
Mechanism of Action
- CB1 activation reduces serotonergic trigeminovascular signaling, implicated in migraine genesis.
- Linalool’s vasodilatory and muscle-relaxing effects reduce cranial tension and vascular inflammation.
Therapeutic Targets
- Migraine with aura
- Tension-type headaches
- Cluster headaches (some off-label reports)
Use Guidelines
- Early-stage dosing is most effective (during prodrome or aura)
- Inhalation is preferred for fast onset
Inflammation and Immune Modulation
Mechanism
- CB2 receptor activation in Purple OG Kush (via caryophyllene) modulates immune cell cytokine production (e.g., reduces IL-1β, TNF-α)
- THC suppresses microglial overactivation, reducing neuroinflammation
- Terpenes such as humulene also exhibit anti-inflammatory properties
Conditions Impacted
- Autoimmune conditions (RA, lupus)
- Chronic inflammatory states (e.g., IBS, endometriosis)
- Neurodegenerative diseases with inflammatory components (Alzheimer’s, MS)
Cancer Symptom Support
While Purple OG Kush is not an anticancer agent, it can relieve multiple symptoms in cancer patients:
| Symptom | Compound Involved | Effect |
|---|---|---|
| Chemotherapy nausea | THC | CB1-mediated antiemetic effect |
| Pain | THC + caryophyllene | Central and peripheral analgesia |
| Appetite loss | THC | Increases ghrelin, improves food intake |
| Anxiety | Limonene + linalool | Cortisol-lowering, mood stabilizing |
| Sleep disturbance | THC + myrcene | Increases sleep duration and depth |
Some lab studies show that high-THC extracts may induce apoptosis in certain tumor cell lines, but these effects are strain- and context-dependent such as in Purple OG Kush and not established in human clinical trials.
