What Is Histamine and Histamine Intolerance?
Histamine is a biogenic amine, a naturally occurring chemical compound involved in several bodily functions, including allergic and inflammatory responses. When the immune system detects a threat, mast cells and basophils release histamine to trigger a defensive reaction. While a normal part of the immune system, an excessive buildup of histamine can lead to symptoms commonly associated with allergies.
Histamine intolerance (HIT) is not a true allergy but a condition where the body cannot effectively break down and metabolize histamine due to a deficiency in enzymes like diamine oxidase (DAO). This leads to an excessive accumulation of histamine, triggering a wide range of symptoms that mimic an allergic reaction. These can include:
- Skin issues such as itching, rashes, and hives
- Respiratory problems like nasal congestion, sneezing, and coughing
- Digestive issues including bloating, diarrhea, and abdominal pain
- Neurological symptoms such as headaches, migraines, and dizziness
- Cardiovascular effects like rapid heart rate and hot flushes
Managing histamine intolerance often involves avoiding high-histamine foods. This raises a crucial question for many health-conscious individuals: where does hemp fit in?
Hemp Seeds and Protein: Naturally Low in Histamine
Hemp seeds and the protein derived from them are not considered high-histamine foods. Unlike foods that are aged, fermented, or cured (like aged cheeses, fermented products, and cured meats), hemp products are fresh and minimally processed. The Swiss Interest Group Histamine Intolerance (SIGHI) specifically classifies hemp seeds as compatible with a low-histamine diet, observing no symptoms after consumption of a usual quantity.
To ensure your hemp seeds remain low in histamine, it is important to follow a few simple rules:
- Choose Freshness: Always use fresh hemp seeds and oil, as histamine levels can naturally increase in any food as it ages.
- Opt for Quality: Purchase from reputable sources to minimize the risk of cross-contamination with other food allergens or high-histamine ingredients during processing.
- Start Small: As with any new food, especially for those with severe sensitivities, start with a small amount and monitor your body’s reaction.
Hemp Oil and CBD: The Cannabinoid Connection
Hemp oil, typically derived from the seeds, contains negligible amounts of cannabinoids and, like hemp seeds, is not considered a source of histamines. However, the interaction of other hemp compounds, particularly cannabinoids like CBD, with the body's systems is where things get more complex. CBD itself does not contain histamine, but it can indirectly influence histamine-related pathways.
Cannabinoids interact with the body’s endocannabinoid system (ECS), which helps regulate immune responses and inflammation. Research suggests that CBD may have anti-inflammatory and immunomodulatory properties. One key area of research involves mast cells, the primary cells that release histamine during allergic reactions. A study published in Molecular Nutrition & Food Research found that CBD inhibited mast cell degranulation and anaphylaxis in mice, suggesting it may help stabilize these cells and reduce histamine release.
However, it is crucial to remember that individual responses can differ. The method of consumption, dosage, and a person's unique physiology all affect how cannabinoids interact with their system.
Comparison: Hemp vs. High-Histamine Foods
| Product | Histamine Level | Reason |
|---|---|---|
| Hemp Seeds | Low | Not fermented or aged; fresh product. |
| Aged Cheese | High | Fermentation and aging process naturally increases histamine. |
| Hemp Protein | Low | Processed from fresh hemp seeds, minimal aging. |
| Fermented Foods (Sauerkraut, Kombucha) | High | The fermentation process produces histamine. |
| Hemp Oil | Low | Cold-pressed from seeds, contains negligible cannabinoids. |
| Cured Meats (Salami, Pepperoni) | High | Curing process relies on fermentation and aging. |
Potential Risks and Considerations for Hemp
While hemp is generally safe for those with histamine concerns, it's not without potential issues for highly sensitive individuals. Here are key points to consider:
- Individual Reactions: The experience with hemp is not universal. Some people with extreme histamine sensitivity or unique triggers may still react, even to low-histamine foods. It's essential to listen to your body and document your reactions.
- Pollen Allergies: Just like other plants, cannabis can cause allergic reactions in some people, particularly from pollen exposure. This is a separate concern from histamine content in the seed or oil.
- CBD and Drug Interactions: The potential interaction of cannabinoids like CBD with the body's systems is complex. For individuals with Mast Cell Activation Syndrome (MCAS) or other related conditions, consulting a healthcare professional is vital to ensure CBD use is appropriate and won't interfere with existing treatments.
- Quality Matters: Low-quality or poorly stored hemp products could potentially develop higher levels of histamine over time or through cross-contamination. Prioritize high-quality, reputable brands for the purest products.
- Method of Consumption: Smoking or inhaling hemp can introduce other irritants and may not be suitable for those with respiratory sensitivities often linked to histamine release. Oral products like oil and edibles are typically safer options.
Practical Tips for Incorporating Hemp into a Low-Histamine Diet
If you have histamine intolerance and want to try hemp products, consider these best practices:
- Start Small: Introduce a very small amount of a high-quality, fresh hemp seed or oil into your diet to test your personal tolerance.
- Choose Minimally Processed: Opt for cold-pressed hemp seed oil and hulled hemp seeds over products with numerous additives.
- Stay Fresh: Always purchase fresh products and store them properly to prevent histamine development over time.
- Consider CBD Separately: If you are interested in CBD for its potential anti-inflammatory benefits, discuss it with a healthcare professional, especially if you have a histamine-related disorder like MCAS.
- Use Third-Party Tested Products: Look for products that are tested by an independent lab to ensure they are free from unwanted contaminants.

Conclusion: Is Hemp Histamine? The Final Verdict
Based on current research and authoritative sources like SIGHI, hemp is not considered a high-histamine food and is generally safe for those following a low-histamine diet. Hemp seeds, protein, and oil are naturally low in histamine, unlike aged or fermented foods. While individual sensitivity is always a factor, especially for those with severe intolerance, hemp offers a nutrient-dense option that typically does not trigger histamine-related symptoms. Furthermore, studies on cannabinoids like CBD show potential anti-inflammatory and mast cell-stabilizing effects, though more research is needed, and individual reactions should always be monitored. As always, consulting a healthcare professional is the best approach for personalized dietary and treatment advice, especially concerning new supplements or existing sensitivities.
