Benefits of CBD Oil - and a Look at Side Effects

Derived from the cannabis plant, CBD oil is a favoured natural solution for various health concerns. Among its advantages are alleviating pain and promoting relaxation, all without inducing cognitive changes.

In today's world, where natural and holistic remedies are increasingly sought after, Cannabidiol (CBD) stands out as a noteworthy ingredient. Extracted from the cannabis plant, CBD oil has garnered significant attention for its potential therapeutic benefits. This article delves into the myriad of advantages attributed to CBD oil, ensuring that readers gain a profound understanding of its scope.

Understanding CBD: What is CBD?

Cannabidiol, more commonly known as CBD, is one of over 100 compounds called cannabinoids found in the cannabis plant. Unlike THC (tetrahydrocannabinol), which is responsible for the 'high' associated with marijuana, CBD is non-psychoactive, meaning it doesn't induce any such effect.

Hemp grown for CBD oil typically contains high CBD levels and minimal THC. This trace amount of THC ensures that users can benefit from CBD without the mind-altering effects linked to THC.

What is CBD used for?

CBD is used for various potential health benefits. People commonly utilise it to help alleviate chronic pain, reduce anxiety and depression, improve sleep, and address inflammatory conditions. Additionally, some evidence suggests its potential in epilepsy management. 

Top Benefits and Uses of CBD Oil

1. Pain Relief

CBD interacts with the body's endocannabinoid system (ECS). This system plays a role in several functions, including pain sensation. By influencing this system, CBD might modulate pain signals, offering relief to sufferers.

Research on CBD and Pain

Numerous studies have looked into CBD's efficacy. Some findings suggest CBD might be beneficial for chronic pain, arthritis, and even migraines. 

Scientists have explored the ability of CBD to alleviate pain. In a minor 2020 study, which was a controlled trial, they examined the application of CBD oil on individuals with peripheral neuropathy affecting their legs.

During this brief research, participants experiencing non-cancer-related neuropathic discomfort were either given 250 milligrams (mg) of CBD (mixed in 3 oz of oil) or a placebo.

After a month, those administering CBD oil exhibited a notable decrease in severe pain, acute pain, sensations of cold, and itchiness. No adverse reactions were reported by the participants.

2. Alleviation of Anxiety and Depression

Mental health disorders, including anxiety and depression, can profoundly affect individuals, often leading to a significant decrease in quality of life, hampering daily functions, and sometimes even resulting in social isolation. The toll of these conditions is not just on the individual but also on their families, communities, and the healthcare system.

In the quest to find effective treatments, CBD oil has emerged as a potential contender. Numerous users and some preliminary studies have highlighted its potential therapeutic effects in managing symptoms of anxiety and depression. One of the mechanisms by which CBD may exert its beneficial effects is its potential influence on serotonin levels in the brain. Serotonin, often termed the 'feel-good' neurotransmitter, plays a pivotal role in mood regulation, social interactions, and overall well-being.

When serotonin levels are imbalanced, it can lead to a myriad of mental health issues, with depression and anxiety being the most common. CBD oil's potential ability to modulate these levels offers hope for those seeking alternatives or adjuncts to traditional pharmaceutical treatments. However, while the early indications are promising, it's essential to approach with caution. Continuous research is necessary to fully understand the long-term effects and the optimal dosing of CBD for mental health conditions. As always, individuals considering CBD oil as a treatment should consult with a healthcare professional to ensure it's appropriate and safe for their specific circumstances.

3. Symptom Reduction in Cancer Patients

CBD might help reduce symptoms related to cancer and side effects of its treatment, such as nausea and pain. Some studies even hint at CBD's potential anti-cancer properties, although further research is needed.

4. Inflammatory Skin Conditions like Acne

Acne, driven by multiple factors, including genetics, bacteria, and inflammation, might be addressed by CBD oil. Its anti-inflammatory properties and ability to reduce sebum production make it a promising solution.

Over recent years, it has garnered significant attention for its potential therapeutic benefits, especially concerning skin conditions like acne and inflammation. In the UK and elsewhere, there's an increasing interest in incorporating CBD into skincare products, driven by a combination of anecdotal evidence and preliminary scientific research.

Acne is a prevalent skin condition that occurs when hair follicles become clogged with oil and dead skin cells. This can lead to the formation of pimples, blackheads, and whiteheads. While several factors contribute to acne, including genetics, diet, and hormonal imbalances, inflammation plays a critical role in its exacerbation. Some research suggests that CBD may possess anti-inflammatory properties that can help reduce the inflammatory response in acne-prone skin. By potentially targeting the root cause – inflammation – CBD may aid in reducing the severity and appearance of acne.

Furthermore, sebum overproduction is another contributing factor to acne development. A study conducted in 2014 found that CBD could regulate the production of sebum from sebaceous glands, indicating its potential in preventing the onset of acne.

Apart from acne, skin inflammation can manifest in various other conditions such as eczema, rosacea, and psoriasis. Preliminary studies and anecdotal reports suggest that CBD may offer relief for these conditions due to its potential anti-inflammatory and immunosuppressive properties. For instance, people with eczema often experience dry, itchy, and inflamed patches of skin. CBD-infused creams and ointments might help soothe these symptoms by hydrating the skin and reducing inflammation.

5. Neuroprotective Properties

Research is in its nascent stages, but CBD's ability to act on the endocannabinoid system and other brain signalling systems could benefit those with neurological disorders.

A piece in Molecules highlights that experiments on animals have demonstrated the potential of CBD to provide protective effects on the nervous system in various neurodegenerative conditions, such as:

  • ALS (amyotrophic lateral sclerosis)
  • Parkinson's ailment
  • Huntington's disorder
  • Alzheimer's affliction
  • MS (multiple sclerosis)

Experts believe that these protective attributes arise due to the anti-inflammatory and antioxidant characteristics of CBD.

6. Managing Addiction

A research piece in the American Journal of Psychiatry delved into the impact of CBD on trigger-related cravings and stress among individuals with heroin addiction. The findings revealed that, in contrast to the placebo group, participants administered with CBD experienced reduced urges and anxiety levels. Such outcomes are encouraging and warrant additional study.
