Proponents claim that CBD oil can treat a wide variety of health problems, including:
Outside of these two disorders, CBD’s effectiveness in treating seizures is uncertain. Even with Epidiolex, it is uncertain whether the anti-seizure effects can be attributed to CBD or some other factor.
Part of this response could be explained by the way that CBD acts in the brain. In low doses, CBD may act as an agonist to several receptor sites, meaning it acts similarly to surrounding molecules that normally bind to the receptor, enhancing the signalling of those receptor sites. At higher doses, however, too much activity at the receptor site can lead to an opposite effect, negating the beneficial effects of CBD.
For this study, nine healthy men took either 600 mg of CBD or the same dose of a placebo. According to the researcher, those treated with CBD had lower blood pressure before and after exposure to stressful stimuli (including exercise or extreme cold).

CBD—the abbreviation for cannabidiol, a substance that’s generally derived from the hemp plant—has skyrocketed in popularity over the last five years. In fact, according to some research, “CBD” as a Google search term remained stable from 2004 to 2014 but has since ballooned by up to 605%.
Some people may get diarrhea or liver problems [when using CBD]. This is dependent on the individual and their medical history, so monitoring is important,” says Dr. Matharu-Daley.
Because CBD supplements come in so many different forms—such as oils, gummies, tinctures, and vapors—the amount that’s actually absorbed can vary drastically. This, combined with each person, will ultimately affect which (if any) CBD side effects you might experience.
Can Interact With Other Medications
“If the CBD is from a reputable source and one that has been inspected by a third-party independent lab, the content of CBD is more reliable,” notes Dr. Matharu-Daley. “The CBD should be organically grown, free of pesticides and heavy metals, and not sourced in food which can affect absorption. Generally, CBD is safe and side effects are few at low doses.”
The most comment side effects of CBD include drowsiness, gastrointestinal issues, dry mouth, reduced appetite, nausea, and interaction with other medications. Those are outlined in detail below.
CBD benefits include the following:
Generally speaking, CBD is considered a safe substance when applied topically or taken orally. There are, however, some potential side effects to keep in mind when using this substance, the majority of which are mild.
Silvers said that the type of allergic reaction depends on the type of exposure. In addition to cannabis pollen allergies and food-based allergies, skin allergies are also a possibility.
While there isn’t much research supporting the idea that CBD oil can help the discomfort associated with common allergy symptoms, there is some research related to its general effects on inflammation, which is part of the body’s allergic reaction process.
He said that cannabis allergies, like other forms of allergies, can worsen as exposure to the allergen continues. Most people with cannabis allergies suffer from a runny and stuffy nose (rhinitis), eye irritation (conjunctivitis), and sometimes wheezing, Sussman explained. But there have been cases of more severe reactions such as anaphylaxis, which have primarily resulted from ingestion of hemp seeds.
Though research is still limited in regards to many supposed benefits, in 2018 the FDA approved Epidiolex, a CBD oral solution, to treat seizures associated with two severe types of epilepsy, Dravet syndrome and Lennox-Gastaut syndrome.
In addition to the skin, the lungs are another target for allergic reactions to terpenes. Assessing the risk is somewhat complicated because some terpenes are irritants, whereas others, such as eucalyptol, may actually provide a protective, anti-inflammatory role and might help to control inflammatory diseases like asthma and COPD.
Such foods may include tomatoes and stone fruits containing pits such as peaches, he said. It’s a similar cross-reactivity to what is seen in people with ragweed allergies who might experience symptoms such as itchy mouth if they eat fruit in the melon family, he added.
A properly functioning immune system works to protect the body from pathogens such as bacteria, viruses, and fungi, and attack these unwanted microorganisms in order to help prevent disease. In the case of allergies, the immune system reacts to plant pollen and other substances in the environment to trigger the body’s defense mechanisms. The result, depending on the type of allergy, can be a variety of symptoms, including itchy eyes, runny nose, asthma, hives, skin itching, or more severe reactions such as anaphylaxis, which can be life-threatening.
