What Is The Difference Between Cannabidiol And Phytocannabinoids

Cannabinoids have garnered significant attention in recent years due to their potential therapeutic benefits and widespread use in wellness products. Among these, cannabidiol (CBD) and phytocannabinoids are two terms often encountered but not always fully understood. This article aims to clarify the distinctions between CBD and phytocannabinoids, offering a comprehensive overview of their unique properties and applications.

CBD is a specific type of phytocannabinoid, one of many naturally occurring compounds found in the cannabis plant. While all cannabinoids interact with the body’s endocannabinoid system, each has unique characteristics and effects. Understanding these differences is crucial for making informed decisions about their use.

Phytocannabinoids, including CBD, have diverse applications in medicine and wellness. They are used to manage various conditions such as pain, anxiety, and epilepsy. The specific benefits and legal status of these compounds can vary, making it essential to grasp their distinct properties and potential impacts on health.


Cannabidiol (CBD)

Definition and Basic Properties

Cannabidiol, commonly known as CBD, is one of the many cannabinoids found in the cannabis plant. Unlike THC (tetrahydrocannabinol), CBD is non-psychoactive, meaning it does not produce a “high” sensation. This characteristic makes CBD a popular choice for those seeking therapeutic benefits without the mind-altering effects associated with cannabis use.

Sources of CBD

CBD can be extracted from both hemp and marijuana plants. Hemp-derived CBD contains very low levels of THC (less than 0.3%), making it legal in many regions. Marijuana-derived CBD, however, often has higher THC levels and is subject to stricter regulations. The choice of source can impact the legal status and availability of CBD products.

Extraction Methods

There are several methods used to extract CBD from cannabis plants, including:

  • CO2 Extraction: This method uses carbon dioxide to extract CBD in a clean and efficient manner. It is considered the gold standard for CBD extraction.
  • Ethanol Extraction: Ethanol is used to strip cannabinoids from the plant material. This method is effective but can sometimes leave behind residual solvents.
  • Oil Extraction: Carrier oils, such as olive or coconut oil, are used to extract CBD. This method is safe but less efficient than CO2 extraction.

Legal Status and Regulations

The legal status of CBD varies worldwide. In the United States, CBD derived from hemp is legal at the federal level, provided it contains less than 0.3% THC. However, state laws can vary, with some states having stricter regulations. In the European Union, CBD products are generally legal if they contain less than 0.2% THC. Always check local laws to ensure compliance.

Medical and Therapeutic Uses

Pain Management

CBD is widely used for its analgesic properties. It interacts with the body’s endocannabinoid system to reduce inflammation and modulate pain. Many people use CBD products such as oils, creams, and edibles to manage chronic pain conditions like arthritis, fibromyalgia, and multiple sclerosis.

Anxiety and Depression

CBD has shown promise in alleviating symptoms of anxiety and depression. It works by interacting with serotonin receptors in the brain, which play a key role in mood regulation. Studies suggest that CBD can reduce anxiety in both human and animal models, making it a potential alternative to traditional antidepressants and anxiolytics.


One of the most well-known uses of CBD is in the treatment of epilepsy, particularly in cases of drug-resistant epilepsy in children. The FDA has approved a CBD-based medication called Epidiolex for the treatment of two rare forms of epilepsy: Dravet syndrome and Lennox-Gastaut syndrome. This approval underscores the potential of CBD as a therapeutic agent for severe neurological conditions.
