Allergies and Their Interaction with CBD
Allergies are adverse immune system reactions to substances that are generally harmless to most people. These substances are called allergens and can be found in dust, pets, pollen, insects, food, and medications. However, there is a lesser-known allergy that has recently generated curiosity and discussion: CBD allergy.
Before we continue, it is worth noting that recent reports generally suggest that CBD actually helps to combat allergies, especially common ones that appear in autumn or spring.
CBD Allergies?
Yes, it is possible to have an allergic reaction to CBD (cannabidiol), although it is relatively rare. CBD is one of many compounds present in the cannabis plant. While known for its therapeutic properties and lacking the psychoactive effect of THC (tetrahydrocannabinol), some people have reported adverse reactions when using CBD products.
Some things to consider when discussing CBD allergies include:
- Reaction to pure CBD vs. additional ingredients: In many cases, allergic reactions associated with CBD products may be due to other ingredients present in the product, and not to CBD itself. For example, CBD oils, tinctures, or topical products may contain base oils, preservatives, colorants, or essences that could be the true cause of the reaction.
- Symptoms of an allergic reaction: Common symptoms of an allergic reaction include skin rashes, itching, hives, swelling, sneezing, nasal congestion, watery or red eyes, and difficulty breathing (in severe cases). If someone experiences these symptoms after using a CBD product, they should stop use immediately and consult a doctor.
- Cross-sensitivity: People with known allergies to pollen or certain types of food may be more susceptible to developing a cannabis allergy. This reaction is due to "cross-sensitivity," where proteins in cannabis are similar to proteins in other allergens.
- Non-allergic adverse reactions: Not all adverse reactions to CBD are due to allergies. Some people may experience side effects such as diarrhea, changes in appetite, or fatigue when consuming CBD. These are not necessarily symptoms of an allergic reaction.
But the best part is when CBD can help reduce or eliminate allergies
CBD (cannabidiol) has been the subject of study in various medical areas due to its anti-inflammatory and analgesic properties. There is evidence suggesting that CBD could be useful in the treatment of allergies and related conditions, thanks to:
- Inflammation Reduction: One of CBD's main characteristics is its ability to reduce inflammation. Allergies often trigger inflammatory responses in the body, such as swelling, redness, and itching. CBD could help alleviate these symptoms by reducing inflammation.
- Immune System Regulation: Allergies occur when the immune system overreacts to harmless substances. CBD is believed to influence the immune response by interacting with endocannabinoid system receptors, which could help regulate and balance the allergic response.
- Reduction of Nasal Congestion: Although CBD is not a decongestant itself, its anti-inflammatory properties could help reduce inflammation of the nasal passages, which in turn could relieve congestion.
- Relief of Skin Symptoms: Allergies can often manifest on the skin, causing rashes, itching, and redness. Some people find relief by applying CBD topicals directly to affected areas.
- Anxiety Reduction: Allergies, especially chronic or severe ones, can be a source of stress and anxiety for some people. CBD is known for its anxiolytic properties, which could help alleviate stress and anxiety associated with allergies.
How are allergies produced?
Allergies are caused by an overactive immune system. When the immune system detects a substance it considers a threat, it produces antibodies. These antibodies remain on alert for any future exposure to the allergen. If you encounter the allergen again, your immune system will release a series of chemicals that cause allergy symptoms, such as itching, sneezing, and congestion.
Stories and curiosities about allergies
Allergies are immune system reactions to substances that are generally harmless to most people. But when were allergies discovered and what are some curiosities surrounding this phenomenon?
Discovery of allergies
The term "allergy" comes from the Greek words "allos," meaning "other," and "ergon," meaning "work." It was proposed by Austrian pediatrician Clemens von Pirquet in 1906 after he noticed that some of his patients showed adverse symptoms after receiving antitoxin injections. The idea was that the immune system "worked differently" or "reacted differently" to certain substances.
Although the concept of allergy as we know it today was defined in the 20th century, allergic reactions such as asthma and hay fever have been described in ancient texts, even in writings from ancient China and Egypt.
Curiosities about allergies

- Geographic location and allergies: People living in cities with high levels of pollution or who live near major roads are more likely to develop allergies.
- The "hygiene hypothesis": There is a theory that suggests that living in overly clean environments during childhood can increase the risk of developing allergies. The idea is that exposure to certain microorganisms during childhood helps mature the immune system.
- Water allergy: Although extremely rare, there is a condition called aquagenic urticaria, where people are allergic to water. Exposure to water can cause hives on the skin.
- Allergies on the rise: Food allergies are on the rise in many industrialized countries. It is estimated that up to 10% of children in countries like Australia have a food allergy.
Can animals have allergies?

Yes, animals can have allergies, just like humans. In fact, it is common for pets, especially dogs and cats, to develop allergies to food, insect bites, pollen, and more.
- Dogs: Some dogs are allergic to certain foods, and this can manifest as skin problems, diarrhea, or vomiting. They can also develop atopic dermatitis, a skin condition caused by environmental allergens like pollen.
- Cats: Like dogs, cats can have food allergies. They are also known to develop asthma, which can be triggered by dust, pollen, and tobacco smoke.
- Birds: Birds can also develop allergies to certain foods, materials in their cages, or even cleaning products.
Who suffers from allergies?
Anyone can develop allergies, although people with a family history have a higher risk. They can also develop at any point in life, although some, especially food allergies, are more common in children.
Times of year and allergies
Seasonal allergies, such as hay fever, generally occur in spring and autumn, while year-round allergies can be caused by things like dust and pets.
CBD and allergies
It is interesting to note that CBD, a molecule derived from hemp, has been on many people's radar for its potential therapeutic properties. But what happens when this compound interacts with our allergic system?
According to the article on "CBD Allergy," it is possible, though rare, to be allergic to CBD oil. This is because full-spectrum CBD oil comes from whole hemp plants, which can result in pollen transfer to the CBD formulation. If this occurs, it can trigger an allergic reaction. Additionally, some terpenes in CBD oil can cause allergic reactions, although this is also uncommon.
It is also important to mention that hemp seeds, rich in protein, can be a potential allergen for some people. On the other hand, CBD has also shown promise in potentially helping the immune system, which could be beneficial for those with allergies.
To consider
Allergies are complex bodily responses to substances it interprets as threats. While rare, it is possible to have an allergic reaction to CBD. However, CBD also has the potential to help with allergies due to its immunomodulatory properties. If you are considering using CBD, whether for allergies or any other purpose, it is essential to consult a healthcare professional first.
