What is histamine intolerance? 

Histamine is an important neurotransmitter/communicator for your brain and body and is essential to your immune health. It’s a naturally occurring chemical found in various foods and is released by immune cells, particularly mast cells, during an allergic response. When released in the body, histamine can cause various effects, including aiding in digestion, wound healing, relaying messages to the brain, and triggering allergic reactions. However, in some individuals, the body may have difficulty breaking down histamine, leading to an accumulation of this compound and resulting in symptoms associated with histamine intolerance. Histamine intolerance symptoms include Acid reflux/indigestion, dizziness, low blood pressure, diarrhea, abdominal pain, bloating, etc.[1] You can learn more about histamine intolerance, potential causes, and tips in this blog post! 

What are herbs that lower histamine?

For centuries, people around the world have been using herbs and spices to add color, flavor, and preserve their food. But did you know that these wonderful ingredients have more to offer than just taste? They have natural properties that can promote good health and help with various things like reducing inflammation, fighting viruses, killing bacteria, healing wounds, and even potentially preventing cancer.[2] Interestingly, cultures that incorporate a generous amount of fresh herbs into their culinary traditions tend to have longer life expectancies compared to those that don’t embrace these herbal wonders.[3] Here are some incredible herbs known for their potential to lower histamine levels and support overall well-being:[2,3] 

• Cilantro
• Dill
• Chives
• Rosemary
• Oregano
• Basil
• Mint
• Sage
• Spearmint
• Thyme 
• Lemongrass

What does the research have to say?

A current review found many investigations for herbs within the lamiaceae family, including basil and spearmint, as well as cloves, ginger, and turmeric.[2] They have focused on how these herbs and spices can fight bacteria and viruses, reduce inflammation, and act as antioxidants.[2] Using these herbs and spices in addition to other healthy habits might help boost the immune system by reducing inflammation, blood pressure, cholesterol, and damage caused by harmful substances in the body.[2] They may even help relieve pain. It’s important to know that the research suggests that regularly using these herbs and spices can support overall immunity and possibly prevent illness, but it doesn’t prove that they can cure diseases.[2] It’s also important to note that you should avoid or restrict anise, cinnamon, cloves, curry powder, paprika, and nutmeg as these herbs can liberate histamine and cause mast cell reactions.[3] 

Another interesting study explored the effects of 20 different essential oils derived from herbal plants and citrus fruits.[4] The researchers found that among the oils tested, lemongrass oil derived from Cymbopogon citratus (DC.) Stapf showed the most potent anti-allergic and anti-inflammatory effects.[4] The main component of lemongrass oil, called citral, was found to be responsible for these effects.[4] Therefore, it might be a good choice to use lemongrass oil to reap extra anti-allergic and anti-inflammatory benefits! 

What are vegetables that lower histamine? 

In addition to incorporating herbs into your diet, including histamine-lowering vegetables is essential for promoting gut health and managing histamine intolerance. The following are histamine lowering, low oxalate, and low lectin vegetables you can emphasize:[3]

• Arugula
• Bok choy
• Broccoli
• Brussels sprouts
• Cabbage, Green, and Red
• Cauliflower
• Collards
• Kale (flat dinosaur or lacinato kind – curly is high oxalate)
• Napa cabbage / Chinese cabbage
• Watercress

You can also try:[3]

• Onions – any kind
• Leeks

So I know what you may be thinking, HOW exactly are these vegetables going to benefit someone with histamine intolerance? Here’s how they can be beneficial:

1. By consuming vegetables that are naturally low in histamine, you can minimize the amount of histamine entering your system, reducing the overall burden on your body.
2. Many histamine-lowering vegetables possess anti-inflammatory properties. Chronic inflammation in the gut can contribute to histamine intolerance. By incorporating these vegetables into your diet, you can potentially reduce inflammation, creating a more favorable environment for histamine regulation.
3. Histamine-lowering vegetables are typically rich in various nutrients, including vitamins, minerals, and antioxidants. These essential compounds support overall gut health and help strengthen your body’s natural defense mechanisms. A healthy gut is better equipped to manage histamine levels effectively.
4. Vegetables high in fiber promote regular bowel movements and support healthy digestion. This can be beneficial for individuals with histamine intolerance, as proper digestion and elimination can prevent the buildup of histamine in the body.
5. Certain histamine-lowering vegetables can also contribute to a healthy balance of gut bacteria. A diverse and thriving gut microbiome is crucial for optimal gut health and histamine regulation.

Bottom Line:

Embracing a holistic approach to managing histamine intolerance can make a world of difference! By incorporating herbs and vegetables known for their histamine-lowering properties, you can take significant strides in managing your symptoms and supporting your overall well-being.
