CBD oil is the common name for Cannabidiol Oil. The Cannabis plant contains more than 113 active ingredients and CBD is one of them. Research has shown that it has potent medicinal properties and therapeutic effects that are far more effective as compared to any other cannabinoid.
In the earlier days, it was considered that CBD has a limited therapeutic role to play in the body. The belief was that THC (tetrahydrocannabinol) was the only active cannabinoid in the plant that could be used medically. In the year 2005, scientists discovered that there was a receptor in the brain called CB2. This CB2 directly interacted with the CBD and lead to therapeutic/medical effects in the patients. This proved to be a turning point and the need for using THC alone was eradicated.
Mode of Action
THC is a cannabinoid that leads to a psychoactive response in the body which is typically described as the high that is associated with the drug.
CBD acts at a different level. It does not induce psychoactive stimulation and is used for medical conditions where it is not required to get a high. It is useful in the following conditions:
- Poor appetite
- Nausea and vomiting
- To relieve muscle tensions
- Antibiotic effect to some extent
- Cancer treatment
- Alzheimers disease
Preparation of CBD Oil
Owing to the gaining popularity of CBD oil in treating various disorders, many companies have begun producing the oil using different methods. Here it is important to note that cannabis oil is different from CBD oil. The major difference is that cannabis oil contains THC so the psychoactive properties are retained. On the other hand, CBD oil is prepared from the cannabis plant and also from hemp which is specifically bred in a way that it has negligible THC content. As a result the psychoactive effect is absent. This kind of selective breeding from hemp has fewer restrictions legally as compared to the preparation of the oil from Cannabis plant.
The methods by which CBD oil is prepared are:
- Ethanol method
- Oil method
- CO2 method
In the ethanol method, alcohol (high grain) is used to extract CBD oil. This is the cheapest method but it has a disadvantage that it can damage a part of the natural oils in the plant.
The Oil method involves the usage of an oil (olive oil) to extract the CBD from the plant. This is the most popular method in use.
The CO2 method or the carbon dioxide method involves the use of CO2 gas which is injected into the hemp or cannabis plant under controlled high pressure in order to extract the CBD oil. This is the most efficient of all the above methods but it is expensive.
Uses of CBD Oil
There are many ways in which this oil can be used. No matter how it is taken, the mode of action within the body remains the same. The administration routes are:
- Placing it sublingually (under the tongue)
- Rubbing it into the skin
- Vaporised form inhalation
There are studies that suggest the efficacy of CBD oil use for people who wish to quit smoking. Inhalation of the CBD oil has known to reduce the craving for nicotine leading to an improvement in the addiction status and making it easier for the person to quit.
It may also be used for those who are addicted to substance abuse with opioids. It helps by reducing the severity of the drug withdrawal symptoms.
CBD oil is beneficial to patients with anxiety disorders, mood symptoms, insomnia and chronic pain.
Ongoing studies suggest that use of CBD oil may be done in treating disorders like epilepsy, neurodegeneration and psychiatric disorders.
The latest use of CBD has been explored in patients with cancer especially leukemia. The cannbinoid helps to block the spread of the cancer cells in the body by promoting the death of the cancer cells. Its synergistic use along with conventional treatment methods is also being explored because of its low toxicity and fewer side effects.
Side effects of CBD Oil

- Withdrawal symptoms like insomnia
