CBG and It’s Potential to Treat TBI/Neurological Disorders

Authored by Anthony Robison

Cannabigerol (CBG) is a non-psychoactive cannabinoid found in the cannabis plant that has garnered attention for its potential neuroprotective properties. Emerging research suggests that CBG may offer therapeutic benefits for various neurodegenerative diseases through several mechanisms:

Antioxidant Effects

Oxidative stress plays a significant role in the progression of neurodegenerative diseases. CBG has demonstrated antioxidant properties that help neutralize harmful free radicals, thereby protecting neurons from oxidative damage. A study comparing the antioxidant effects of cannabidiol (CBD) and CBG found that both cannabinoids effectively reduced oxidative stress in rat astrocyte cells exposed to hydrogen peroxide, suggesting potential neuroprotective benefits. 

Anti-inflammatory Actions

Chronic neuroinflammation is a common feature of many neurodegenerative conditions. CBG appears to modulate inflammatory responses by influencing cytokine production and reducing the activation of inflammatory pathways. In models of Huntington’s disease, CBG treatment improved motor deficits and preserved striatal neurons, effects attributed to its anti-inflammatory properties. 

Modulation of Neurotransmission

CBG interacts with the endocannabinoid system and other receptor systems, potentially affecting neurotransmitter release and neuronal excitability. This modulation may help maintain neuronal balance and prevent excitotoxicity, a process that can lead to neuronal injury and death. Research indicates that CBG’s interaction with α-2 adrenoceptors and 5-HT1A receptors may contribute to its neuroprotective effects. 

Preclinical Studies and Potential Applications

In various in vitro and animal studies, CBG has shown promise in models of neurodegenerative conditions such as Huntington’s and Parkinson’s diseases. For instance, in a study involving mice lesioned with the neurotoxin 3-nitropropionate (3NP), CBG treatment improved motor deficits and preserved striatal neurons. Additionally, derivatives of CBG, like VCE-003.2, have demonstrated neuroprotective effects in models of Parkinson’s disease by preserving nigral neurons and reducing glial reactivity. 

Conclusion

CBG’s combination of antioxidant and anti-inflammatory effects, along with its influence on neuronal signaling, positions it as a potentially valuable compound in combating neurodegeneration. While current evidence is primarily preclinical, these findings underscore the need for further research to determine whether CBG’s neuroprotective properties can be translated into effective therapies for neurodegenerative diseases in humans.

When to Harvest Organic Cannabis: Trichomes vs. Senescence

Authored by: Anthony Robison Harvesting cannabis at the right time is crucial for maximizing potency, flavor, and overall quality. When growing organically, some growers wonder whether they should wait for natural senescence (the plant’s natural fading process) or rely on trichome development to determine the best harvest time. The short answer? Trichome maturity should be your primary guide, while senescence can be a secondary indicator. Here’s why. Trichomes: The Most Reliable Harvest Indicator Trichomes are the tiny, crystal-like resin glands on cannabis flowers that contain cannabinoids and terpenes. By monitoring their color and maturity, you can pinpoint the ideal harvest window. Trichome Color Guide for Harvesting: Clear Trichomes “ Too early; cannabinoids are still developing. Cloudy (Milky) Trichomes “ Peak THC potency; best for strong, euphoric effects. Amber Trichomes “THC is degrading into CBN, leading to more sedative effects. For most growers, the sweet spot is when most ...

Boosting Trichome & Resin Production in Cannabis with Chitin

Authored by: Anthony Robison Cannabis cultivators are always looking for ways to enhance trichome density and resin production. One of the most effective but often overlooked methods is using chitin, a natural compound that can significantly boost cannabinoid and terpene output. But how does it work, and how can growers use it effectively? Let’s dive in. What Is Chitin? Chitin is a naturally occurring biopolymer found in the exoskeletons of insects, crustaceans (like crabs and shrimp), and the cell walls of fungi. When introduced to cannabis plants, chitin triggers natural defense mechanisms, leading to increased trichome production and resin content. How Chitin Enhances Trichome & Resin Production 1. Activates the Plant’s Defense Response Cannabis plants rely on trichomes to protect themselves from pests, UV radiation, and environmental stressors. When the plant detects chitin, it interprets it as a sign of insect or fungal attack, triggering: Systemic Acquired Resistance (SAR): ...

How Senescence Affects Cannabis Flavor

Authored by: Anthony Robison One of the biggest questions for organic cannabis growers is whether to wait for natural senescence before harvesting or cut the plant down while it’s still green. Timing your harvest correctly can make a huge difference in flavor, smoothness, and overall quality. But does harvesting before senescence lead to a more grassy taste? And can allowing senescence to occur help cannabis release chlorophyll quicker during drying? Does Harvesting Before Senescence Lead to a Grassy-Tasting Product? Yes, harvesting before senescence can result in buds that taste more “grassy” or “hay-like” this is because the plant still contains high levels of chlorophyll and nitrogen-based compounds, which contribute to the fresh-cut grass aroma and harsher smoke. Why Early Harvesting Affects Flavor: 1. Higher Chlorophyll Content “ Young, green plant material holds more chlorophyll, making the smoke harsher and less flavorful. 2. Slower Chlorophyll Breakdown “ If too much chlorophyl...
