CBD Oil for Cancer: The Potential of Cannabis

CBD oil - a natural extract from the cannabis plant - has recently gotten significant attention from both the scientific community and the general public due to its many potential therapeutic benefits. A lot of people are curious about the potential of CBD oil as an alternative or supplementary treatment for cancer. And the rising interest in this topic has led to research focusing on the potential applications of CBD oil in cancer management.

Although preliminary findings show promise, the scientific evidence around the efficacy of CBD oil for cancer is still in its early stages! At present CBD oil should not replace conventional cancer treatments. However, it may be considered as a supplementary therapy. As always: it's important to consult with a healthcare professional before starting any new treatment or making changes to your existing treatment plan! Please note that the information provided in this article is not intended as medical advice and should not be considered a substitute for professional medical guidance.

Understanding CBD Oil and Cannabis

CBD (short for cannabidiol) is an increasingly popular compound derived from the cannabis plant. Unlike the high-inducing compound found in marijuana - THC - CBD does not have any psychoactive effects. In fact, it even has anti-psychotic properties [1]. This is making it an attractive option for those seeking potential health benefits without the "high". 

CBD is in most cases extracted from the hemp plant - a cannabis variety which is naturally lower in THC content. This means that most CBD oils made from this ingredient contain only trace amounts of THC (if any), bringing them into accordance with UK and EU regulations. There are several extraction methods, but solvent extraction (either using liquid CO2 or alcohol) is by far the most common and sustainable one. 

The final CBD oil (or cannabis oil) product can be classified into three main categories: full-spectrum CBD, broad-spectrum CBD and CBD isolate. Full-spectrum CBD oil contains all the compounds found in the cannabis plant - including both CBD and THC. These come along with many other cannabinoids, terpenes and flavonoids. This type of CBD oil is believed to offer the most benefits due to the "entourage effect", a synergistic interaction between all these compounds [2]. However due to the trace amounts of THC it might not be suitable for some users.

Broad-spectrum CBD oil is largely the same as full spectrum. It contains a wide range of cannabis compounds but the THC is completely removed. This type of oil can offer a similar entourage effect to full-spectrum CBD but without the potential concerns related to THC. CBD isolate is the purest form of cannabidiol with all other cannabis compounds removed. This type of product is ideal for those who want to experience the potential benefits of CBD on its own.

When shopping for CBD oil in the UK and EU, look for products that clearly specify the content and the type of CBD they contain. Harmony is a well-known brand that offers a range of high-quality CBD products including oils, topicals and e-liquids. Always look for third-party lab results (COAs) to ensure purity and consistency. By understanding the differences between full spectrum, broad spectrum and Isolate you can choose the type of CBD oil that best suits your preferences and needs.

CBD Oil and Cancer Treatment

In the context of cannabis and CBD for medical use, the National Cancer Institute states that some studies have shown promising results in using cannabis oil and other cannabis-derived compounds for cancer treatment [3].

One case report describes a reduction in tumour size of a lung cancer patient following self-administration of CBD oil [4]. However - this is only one instance and cannot be interpreted as proof. In another study researchers investigated the accompanying use of cannabinoids in the treatment of non-small cell lung cancer with promising results [5]. However - this study had a narrow application and further research is needed.

So it is safe to say that a lot more research is needed to fully understand the potential of medicinal cannabis in treating cancer and that CBD oil is not a cure for cancer. CBD oil may show promise in some types of cancer but it may not have the same efficacy across different types or stages of the disease. The findings mentioned above are only initial steps in understanding the potential role of CBD in cancer treatment. 

CBD oil is available in the UK as a food supplement designed to be integrated into your daily routine to support overall wellness. However - before supplementing your treatment plan with CBD oil or any other cannabinoid - always consult with your healthcare professional.

CBD Oil for Cancer Patients

Cancer patients often seek ways to alleviate the symptoms and side effects associated with their treatment. In this context CBD oil has gained popularity. Let's explore how cancer patients could use CBD oil in their journey.

Alleviating Cancer Symptoms

CBD oil might help in managing cancer symptoms such as chronic pain [6], anxiety [7], nausea and loss of appetite. Some cancer patients find relief in using CBD oil in conjunction with their existing treatment plan. 

Cancer Pain Management

Cancer pain can be excruciating and traditional painkillers might not always be sufficient. A study has shown that combining THC and CBD extracts can help reduce pain in patients with advanced cancer [8]

Limiting Side Effects

Cancer treatments often come with an array of unpleasant side effects. If you consider using CBD oil for cancer side effects like nausea and loss of appetite - consult your doctors before making any adjustments to your treatment plan.

Use Responsibly

While many cancer sufferers report success in alleviating some of the symptoms and side effects of cancer and cancer treatment with CBD, it's essential to use it responsibly! Always communicate with your medical team and follow their guidance when incorporating CBD oil into your cancer treatment plan. No matter how you choose to utilise CBD oil - keep in mind that it should only be considered a supportive measure to complement your prescribed cancer treatment options.
