What to know about CBD extract
Cannabidiol (CBD) extract comes from the cannabis plant. Typically, CBD extract is an oil, which manufacturers add to various products, such as creams and lotions. People use CBD extract as treatment for a range of conditions, but there is no scientific evidence to back it up.
In recent years, consumers and researchers have grown more interested in the potential health benefits of CBD extract. The research is promising and suggests there are some tangible benefits. However, in-depth scientific research has not yet caught up to the wide claims consumers and CBD companies make about these products.
The Food and Drug Administration (FDA) has only approved CBD to treat a few rare seizure disorders in children. This means that its use for other conditions remains unregulated and unapproved.
People interested in CBD should research manufacturer claims and discuss potential drug interactions with a doctor.

Is CBD legal?The 2018 Farm Bill removed hemp from the legal definition of marijuana in the Controlled Substances Act. This made some hemp-derived CBD products with less than 0.3% THC federally legal. However, CBD products containing more than 0.3% THC still fall under the legal definition of marijuana, making them federally illegal but legal under some state laws. Be sure to check state laws, especially when traveling. Also, keep in mind that the FDA has not approved nonprescription CBD products, and some products may be inaccurately labeled.
Cannabidiol is a non-psychoactive component of the cannabis plant. This means that it will not get a person high. Tetrahydrocannabinol (THC) is the substance that produces a high.
Most CBD products sold in the United States are derived from low-THC hemp varieties of cannabis and only contain trace quantities of THC that do not cause a high.
Any substance that comes from a cannabis plant and contains CBD is technically a CBD extract. In most cases, however, CBD extract is synonymous with CBD oil. It is possible to add CBD oil to various products, including lotions, creams, tinctures, and pills.
People use CBD extract because they believe it offers health benefits.
CBD is a compound that comes from the cannabis plant. Growers extract it from the plant’s flowers or leaves.
There are several different methods of extraction. For example, some large-scale manufacturers use chemicals, such as carbon dioxide or ethanol, to separate CBD from the plant.
Many studies have investigated the potential benefits of CBD extract and offer promising results. However, due to a lack of human research, there is no conclusive evidence that CBD can treat medical conditions, such as pain, inflammation, anxiety, and insomnia.
However, other studies have serious shortcomings, such as small sample sizes, the use of animals rather than people, or only looking at models in vitro, or in Petri dishes, in a lab.
For this reason, there is a lack of conclusive evidence that CBD could be a viable substitute for many standard medical treatments. It may, however, be a valuable add-on to traditional interventions.
The FDA has also raised numerous concerns about the purity and content of over-the-counter (OTC) products claiming to contain CBD. Typically, the FDA does not regulate or test CBD products.
However, some products that they have investigated do not contain the amount of CBD the manufacturers claim. This makes it difficult to determine an adequate dosage of CBD, which may reduce the likelihood of experiencing any benefits.
CBD users and manufacturers cite that CBD has various benefits, including curing cancer and treating acne. There may be health benefits that scientists have not yet identified with well-designed research since scientific research can take a long time.
However, because current research is limited, people should use CBD with caution. It is not advisable to use CBD in the place of traditional treatments unless a doctor advises it.
However, some of the most well-documented potential benefits include:
The FDA has approved a drug containing CBD called Epidiolex to treat two rare forms of epilepsy, Lennox-Gastaut and Dravet syndrome. Both forms of epilepsy typically appear in childhood and can be debilitating. They also tend to be resistant to traditional seizure treatments.
Improving gastrointestinal symptoms
A 2020 paper cites several previous studies suggesting that CBD may play a role in digestive health. In general, CBD can slow down digestion, which may help with diarrhea and related issues, such as nausea.
Some other potential benefits suggested by preliminary research include:
- easing symptoms of irritable bowel syndrome (IBS)
- reducing heartburn
- relieving nausea, especially chemotherapy-related nausea
- reducing the inflammation that causes pain in inflammatory bowel disease (IBD)
Slowing the growth of cancer cells
Several small studies suggest that CBD might slow the growth of cancer cells. However, these studies have looked at cancer cells in a lab setting and not in humans.
A 2019 study , for example, found that in a lab setting, CBD might limit the growth of tumors or encourage cell death in pancreatic cancer cells. The study’s authors suggest that CBD might be a useful addition to traditional pancreatic cancer treatments.
Another 2019 study of cancer in a laboratory setting, suggests that in glioblastoma, a type of brain cancer, cells treated with CBD released lower quantities of chemicals that promote cell growth.
There is currently no evidence suggesting that CBD can cure cancer or is a viable alternative to chemotherapy and similar cancer treatments.
The FDA has also approved t he drugs Marinol and Syndros to treat nausea and vomiting following chemotherapy. Though there is no CBD in these drugs, they do contain a synthetic form of THC.
Managing chronic pain
Research suggests that CBD may help ease chronic pain by fighting inflammation.
A 2019 study, for example, followed 97 patients at a pain clinic for 8 weeks. All had been taking opioids for pain relief for at least a year.
After adding CBD-rich hemp extract to their treatment regimen, 53% were able to reduce their reliance on opioids, and 94% of CBD users said their quality of life had improved.
However, this was an observational study without the necessary elements of a clinical trial that can drive conclusions such as blinding, randomization, and placebo control.
An Arthritis Foundation survey of 2,600 people found that 79% of respondents use, have used, or are considering using CBD to treat arthritis pain.
Because arthritis is often resistant to other treatments, the Arthritis Foundation has urged the FDA to expedite trials on CBD extract for arthritis and other types of chronic pain.
Supporting mental health
Many cannabis users, including CBD users, claim that it improves their mental health.
A 2020 systematic review found moderate evidence for the use of CBD to manage schizophrenia and social anxiety based on rigorous human clinical trials.
