Whether it’s sniffling, watery eyes, itching, or asthma, many of us are all too familiar with symptoms of allergies.
According to the Asthma and Allergy Foundation of America, allergies are the No. 6 cause of chronic illness in the United States. To narrow that down,there were 19.9 million adults diagnosed with hay fever in 2017, according to the Centers for Disease Control and Prevention (CDC). It is estimated that 32 million Americans live with food allergies; more than 170 foods may lead to allergic reaction.
Considering the increasing awareness and use of cannabidiol (CBD) and the existing potential for pollen and food allergies, allergy sufferers may wonder whether they are at risk for an allergic reaction to CBD oil or whether CBD can provide treatment or relief for other types of allergic reactions.
Though there’s not much in the way of allergy research specifically for CBD oil at this point, the cannabis plant itself has been linked to allergic reactions.
“Marijuana is a plant and produces pollen and one can become allergic to the pollen and the plant, especially if one has pre-existing allergic tendencies,” said Dr. William S. Silvers, clinical professor of medicine in allergy and immunology at the University of Colorado School of Medicine.
That being said, only male marijuana plants produce pollen, and are exceedingly rare in cannabis and hemp production because they produce less oil and CBD than female plants. Therefore, a consumer’s exposure to pollen would be extremely rare.
CBD oil overview
CBD is the second-most-prominent cannabinoid derived from the cannabis plant, after the intoxicating cannabinoid THC. CBD oil, extracted from marijuana or industrial hemp, has gained popularity for its potential benefits for a number of conditions, including inflammation, arthritic pain, depression, seizures, and anxiety.

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.
Allergies in the body
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.
Allergic reactions to CBD oil
Humans commonly experience allergic reactions to many kinds of plant pollen. However, only male cannabis plants produce pollen, whereas female plants are more widely used for oil and cannabinoid production. Large-scale industrial hemp fields may include a variety of mature males (pollen) as well as fertilized females (oil and seeds). The impact of hemp pollen on everyday consumers, as well as the communities that work and live near these production facilities, has not been studied.
People can also develop allergies to some of the terpenes found in cannabis. For instance, researchers from the Duke University School of Medicine found that about 20% of the 100 people they tested had an allergic skin reaction to linalool, whereas 8% had reactions to limonene. These kinds of contact allergies may not be common in the general population, but individuals who are employed in the production of cannabis products and CBD oil could be more at risk.
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.
Dr. Gordon Sussman, an allergist in Canada and professor at the University of Toronto, said there is very little published research on CBD oil allergies.
“It’s an unknown area at this point,” he said. “But we know that cannabis sativa is an allergen and we know that it’s a common allergen.”

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.
According to a letter entitled “Marijuana and stoned fruit,” written by medical doctors from the University of California, San Diego, and published in the Annals of Allergy, Asthma, and Immunology on Feb. 2, 2018, a 24-year-old man who smoked marijuana daily visited their allergy clinic two weeks following an anaphylactic reaction after eating yogurt with hemp seeds.
“This was his first known ingestion of hemp seeds. Immediately after consumption, he developed oral pruritus [itching] that progressed to shortness of breath, facial swelling, and pre-syncope [sensation prior to fainting],” the letter stated.
Those with food allergies may also be susceptible to cross-reactivity.
“You can have a cross-reaction with certain foods that share certain antigens, certain components, with the cannabis plant itself,” Silvers said.
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.
“The same thing goes with cannabis and tomatoes and peaches and almonds and a number of other foods … eggplant, grapefruit, apples,” Silvers said.

A 2013 study from the “Internal Archives of Allergy and Immunology” tested 21 patients with food allergies for reactivity to cannabis lipid transfer proteins (LTPs), which are probable allergens. Twelve of the 21 test subjects were allergic to cannabis, and all 12 had more severe reactions to food allergy than those without a cannabis allergy. A 2008 study, also from “Internal Archives of Allergy and Immunology,” tested 32 subjects for an allergic reaction to cannabis LTPs, as well as tomato, peach peel, and pollen extracts. The study found that all test subjects sensitive to tomato allergens were also sensitive to cannabis. There was also cross-reactivity noted with peach peel.
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.
“Touching the plant can very easily develop a dermatitis, itching, and skin reactions,” he said.
Can CBD oil help with allergies?
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.
A 2011 research report published in the journal Free Radical Biology and Medicine examined the potential role of CBD in various inflammatory-type conditions. George W. Booz, a professor in the department of pharmacology and toxicology at the University of Mississippi Medical Center, concluded in the report: “Inflammation and oxidative stress are intimately involved in the genesis of many human diseases. Unraveling that relationship therapeutically has proven challenging, in part because inflammation and oxidative stress ‘feed off’ each other. However, CBD would seem to be a promising starting point for further drug development given its antioxidant (although relatively modest) and anti-inflammatory actions on immune cells … .”
According to Silvers, there is no clinical evidence CBD oil can help allergies and, while experimental laboratory research suggesting anti-inflammatory effects exists, there’s no clinical patient substantiation.

How Does CBD Oil Help Skin Conditions?
Skin conditions ranging from acne to dry and aging skin can be helped by CBD oil products. The best CBD option for your needs depends on your particular skin condition.
The skin is the body’s largest organ, as well as its first line of defense against illnesses and infections. For this reason, it is exposed to danger more than any other part of the body, and skin conditions are therefore quite prevalent. No one is immune to the occasional rash. Others face lifelong autoimmune disorders, including eczema, psoriasis, and dermatitis. Skin conditions are exacerbated by inflammation. And, since CBD oil is known to be a potent anti-inflammatory agent, more and more people are using CBD oil for skin conditions, both for treatment and prevention.
Skin conditions: the common denominator
There are many common skin conditions.
- Atopic dermatitis, otherwise known as eczema, presents as a rash on the arms and behind the knees. Irritating as it is, it can be resolved within weeks.
- Contact dermatitis refers to a rash caused by contact with an allergen.
- Rosacea, common in people with fair skin, presents as red, itchy skin, and pus-filled bumps on the face.
- Psoriasis is a chronic condition that causes scales and dry itchy patches on the skin. It is thought to be an immune system problem.
- Basal cell carcinoma is the most common of all skin cancer types.
All of these conditions have one thing in common: they are exacerbated by inflammation. Inflammation is a crucial natural process used by the body to protect against pathogens and irritants. However, with certain conditions, the inflammatory process only makes things worse, as is the case with skin conditions.
The endocannabinoid system (ECS) and inflammation
Since skin conditions are exacerbated by inflammation, studies have been done to determine whether CBD oil can be used to treat and prevent them. Results have been positive, and this is just one reason to use CBD oil to treat common skin conditions.
The ECS and other regulatory functions
But CBD’s properties are not only anti-inflammatory. The endocannabinoid system has been connected specifically to the skin, with functions regulating skin proliferation, growth, differentiation, hormone production, and more.
Therefore, CBD oil is useful in treating the root causes of skin conditions, and not just the accompanying inflammation.
Furthermore, CBD can stop the proliferation of keratinocyte, which is a key factor in psoriasis. CBD is also known to kill cancer cells, and it can be used for basal cell carcinoma as well.
Prevention and maintenance
CBD oil is becoming popular as a preventative measure against skin conditions. It stops flare-ups from happening due to the endocannabinoid system’s role in regulating functions affecting the skin. Its anti-inflammatory properties help prevent conditions caused by inflammation.
Also, CBD has antibacterial properties and is a strong antioxidant. Because of this, it can be used to protect the skin against the sun’s ultraviolet rays, which can lead to skin cancer.
Topical CBD oil
The most effective way to use CBD oil for skin conditions is to apply it topically. It is absorbed easily and has no harmful side-effects. It can also be used for healthier and younger looking skin, due to its antioxidant properties.
If you suffer from any skin conditions, use CBD oil to relieve pain and itching, prevent further inflammation, and promote healing.
