  • THC: 22% – 30%
  • CBD: <1%
  • CBG: 1% – 2%
  • THCV: Trace amounts

The dominant presence of THC makes it a potent strain, best suited for experienced users or those who require strong therapeutic effects.

Terpene Profile

Rainbow Glue’s terpene composition contributes to its effects, aroma, and medicinal benefits. Key terpenes include:

  • Myrcene: Provides sedative, pain-relieving, and anti-inflammatory properties.
  • Limonene: Offers mood-enhancing and stress-reducing benefits.
  • Caryophyllene: Known for its potential to interact with CB2 receptors, offering anti-inflammatory and analgesic effects.
  • Pinene: Improves focus, respiratory function, and counteracts some sedative effects.
  • Humulene: Aids in appetite suppression and has anti-inflammatory benefits.
Medical Uses of Rainbow Glue
1. Mechanism of Action: How Rainbow Glue Works in the Body
Interaction with the Endocannabinoid System (ECS)

The primary medical effects of Rainbow Glue stem from its interaction with the endocannabinoid system (ECS), which regulates:

  • Pain perception
  • Mood & stress response
  • Neuroprotection
  • Sleep & circadian rhythm
  • Appetite & digestion
  • Immune function
Key Receptor Interactions
  • CB1 Receptors (Central Nervous System)
    • THC binds to CB1 receptors in the brain, altering neurotransmitter release (dopamine, serotonin, and GABA).
    • Produces pain relief, euphoria, muscle relaxation, and anti-anxiety effects.
  • CB2 Receptors (Immune & Peripheral Systems)
    • Caryophyllene binds directly to CB2 receptors, exerting anti-inflammatory and analgesic properties.
    • Helps modulate immune response and inflammation.
2. Pain Management

Rainbow Glue is highly effective for pain relief due to its high THC content (22-30%), which modulates pain pathways in the spinal cord and brain.

Conditions Treated
  • Chronic Pain (Neuropathic & Inflammatory)
    • Neuropathy: THC and CBG help regulate overactive nerve pain signaling.
    • Fibromyalgia: Reduces widespread musculoskeletal pain via serotonergic modulation.
    • Arthritis & Rheumatoid Arthritis: Caryophyllene and THC reduce joint inflammation.
  • Migraine & Headache Disorders
    • THC activates 5-HT1A serotonin receptors, reducing migraine severity.
    • Pinene acts as a bronchodilator, improving oxygenation in the brain.
  • Post-Surgical & Injury Pain
    • THC and myrcene induce analgesia comparable to opioids, reducing reliance on pharmaceutical painkillers.
Scientific Studies Supporting Cannabis for Pain
  • A 2020 study in the Journal of Pain found that THC-rich cannabis strains reduce neuropathic pain by 40%.
  • A 2019 study in JAMA Neurology concluded that cannabinoids improve chronic pain management and reduce opioid dependence.
3. Mental Health Benefits

Rainbow Glue’s high THC and limonene content contribute to its mood-enhancing and anxiolytic effects.

Conditions Treated
  • Anxiety Disorders such as (Generalized Anxiety, Social Anxiety, PTSD)
    • Limonene and myrcene modulate cortisol levels, reducing stress response.
    • THC at low doses (<10 mg) promotes relaxation; higher doses (>20 mg) may cause anxiety.
  • Depression & Mood Disorders
    • THC enhances dopamine signaling, producing an antidepressant-like effect.
    • Limonene has been studied for its antidepressant properties via serotonin receptor activation.
  • PTSD (Post-Traumatic Stress Disorder)
    • THC suppresses hyperactive amygdala responses, reducing intrusive thoughts and nightmares.
    • CBD (even in trace amounts) contributes to emotional regulation.
Scientific Studies on Cannabis for Mental Health
  • A 2017 study in Neurotherapeutics found that cannabis reduces PTSD-related symptoms by over 50% in military veterans.
  • A 2022 study in Molecular Psychiatry confirmed that limonene improves serotonin and dopamine regulation, reducing depression severity.
4. Sleep Disorders & Insomnia

Rainbow Glue’s high myrcene and THC content makes it a potent sleep aid, particularly for individuals with chronic insomnia or sleep disturbances.

How It Works
  • THC reduces REM sleep, which can help people with nightmares or PTSD-related insomnia.
  • Myrcene acts as a sedative, increasing deep (NREM) sleep and promoting longer sleep durations.
  • CBN (Cannabinol, a degradation product of THC) has strong sedative effects, making aged Rainbow Glue flowers more effective for sleep disorders.
Scientific Studies on Cannabis for Sleep
  • A 2021 study in Sleep Medicine found that cannabis users fell asleep 30 minutes faster on average.
  • A 2019 study in Frontiers in Pharmacology confirmed that high-myrcene strains induce longer sleep duration and deeper rest.
5. Neurological Disorders
Epilepsy & Seizure Management
  • While Rainbow Glue is low in CBD, it still exhibits anticonvulsant properties due to CBG and myrcene.
  • CBG (Cannabigerol) blocks GABA uptake, reducing seizure frequency.
  • Pinene enhances memory function, reducing cognitive impairment associated with seizures.
Multiple Sclerosis (MS) & Spasticity
  • THC reduces muscle spasticity and tremors by modulating CB1 receptors in the spinal cord.
  • Caryophyllene reduces neuroinflammation, which is critical in MS management.
Alzheimer’s & Neurodegenerative Diseases
  • THC reduces beta-amyloid plaque formation, a hallmark of Alzheimer’s disease.
  • Limonene and myrcene protect neurons from oxidative stress and inflammation.
Scientific Studies on Cannabis for Neurological Disorders
  • A 2018 study in the British Journal of Pharmacology found that CBG and THC reduce spasticity in multiple sclerosis patients.
  • A 2020 study in Frontiers in Aging Neuroscience showed that THC slows the progression of Alzheimer’s disease by reducing neuroinflammation.
6. Gastrointestinal and Appetite Disorders
Nausea & Vomiting (Chemotherapy-Induced & Gastrointestinal Disorders)
  • THC activates CB1 receptors in the gut, reducing nausea signals in the medulla oblongata (brainstem).
  • Limonene has anti-emetic properties, further reducing nausea severity.
Appetite Stimulation & Cachexia
  • THC stimulates ghrelin production, increasing appetite in patients suffering from:
    • Cancer-related weight loss.
    • HIV/AIDS-related wasting syndrome.
    • Anorexia and other eating disorders.
IBS & Crohn’s Disease
  • CBG reduces intestinal inflammation and spasticity, improving digestion.
  • Caryophyllene interacts with CB2 receptors, reducing symptoms of Crohn’s and ulcerative colitis.
Scientific Studies on Cannabis for GI Disorders
  • A 2020 study in Gastroenterology confirmed that cannabis reduces inflammation and pain in IBS patients.
  • A 2019 study in the Journal of Palliative Medicine found that THC-rich cannabis strains increased appetite in cancer patients by 50%.
7. Anti-Inflammatory & Immune System Benefits

Rainbow Glue is effective in modulating immune responses, making it useful for autoimmune and inflammatory conditions.

Conditions Treated
  • Arthritis & Joint Inflammation: Caryophyllene acts as a CB2 agonist, reducing inflammation in joints.
  • Autoimmune Diseases (Lupus, Crohn’s, Psoriasis): THC suppresses excessive immune activation, reducing symptom severity.
