Cannabigerol (CBG) Therapeutic Effects: Key Mechanisms and Applications
CBG Pharmacological Targets and Mechanisms of Action
Cannabigerol (CBG) is a non-psychoactive cannabinoid found in Cannabis sativa that interacts with several biological targets. It acts as a partial agonist at CB1 and CB2 cannabinoid receptors, and also influences alpha-2-adrenergic receptors, transient receptor potential (TRP) channels, cyclooxygenase enzymes (COX-1 and COX-2), and 5-HT1A receptors. These interactions allow CBG to modulate endocannabinoid signaling and other key physiological pathways, contributing to its diverse therapeutic effects Li2024Calapai2022.
Anti-Inflammatory and Antioxidant Properties
CBG has demonstrated strong anti-inflammatory and antioxidant effects in both in vitro and in vivo studies. It reduces the expression of inflammatory cytokines and markers, such as IL-1β, IL-6, and TNF, and modulates key signaling pathways like JAK/STAT and NF-κB. These effects have been observed in models of atopic dermatitis, where CBG alleviated symptoms and improved skin barrier function . Additionally, CBG protects cells from oxidative stress by activating CB2 receptors, reducing oxidative markers, and enhancing antioxidant defenses, which may be beneficial in oxidative-stress-related disorders Giacoppo2017Jastrząb2022.
Neuroprotective, Anxiolytic, and Antidepressant Effects
Preclinical research suggests that CBG has neuroprotective properties and may help in the management of neurodegenerative diseases. It also exhibits anxiolytic and antidepressant effects, as shown in animal studies and a recent human trial. In a double-blind, placebo-controlled study, acute CBG administration significantly reduced anxiety and stress in healthy adults without causing cognitive or motor impairment, indicating its potential as a novel option for mood regulation Li2024Calapai2022Cuttler2024.
Cardiovascular and Metabolic Benefits
CBG may offer therapeutic benefits for cardiovascular and metabolic conditions. It has been shown to lower blood pressure in animal models, likely through its agonist action on alpha-2-adrenergic receptors, which reduces norepinephrine release. CBG also improves tissue sensitivity to insulin and inhibits platelet aggregation, suggesting potential applications in treating hypertension and metabolic syndrome. However, high doses may adversely affect liver function, highlighting the need for further safety studies Krzyżewska2025Vernail2022.
Anticancer Activity
CBG exhibits promising anticancer effects, particularly in glioblastoma and leukemia models. It impairs the viability and invasiveness of glioblastoma cells, including therapy-resistant stem cells, and induces apoptosis in acute myeloid leukemia cells. These effects are comparable to or synergistic with other cannabinoids like CBD, and suggest that CBG could be a valuable component in combined cancer therapies Li2024Calapai2022Lah2021+1 MORE.
Additional Therapeutic Applications
CBG has shown potential in reducing intraocular pressure, making it a candidate for glaucoma treatment. It also demonstrates anti-anxiety, dermatological, and appetite-stimulating effects, and may have antibacterial and antifungal properties. Its rapid metabolism and lack of psychoactive effects further support its suitability for therapeutic use Calapai2022Jastrząb2022.
Conclusion
CBG is a versatile cannabinoid with a broad spectrum of therapeutic effects, including anti-inflammatory, antioxidant, neuroprotective, anxiolytic, cardiovascular, metabolic, and anticancer activities. While preclinical and early clinical data are promising, more research is needed to fully understand its safety profile and long-term effects in humans. CBG’s unique pharmacological properties make it a promising candidate for future therapeutic applications across a range of health conditions Krzyżewska2025Li2024Calapai2022+7 MORE.
