Dill is considered a low-histamine herb. It falls into the “well tolerated” category on the SIGHI (Swiss Interest Group Histamine Intolerance) food compatibility list, which is one of the most widely referenced guides for people managing histamine intolerance. Fresh dill and dried dill are both generally safe to include in a low-histamine diet.
Where Dill Sits on Histamine Food Lists
The SIGHI histamine elimination diet guide groups dill under “culinary herbs” and rates it as well tolerated. This is the lowest risk category, meaning it’s not expected to raise histamine levels, trigger histamine release from your own cells, or block the enzyme that breaks histamine down in your gut.
Other food list databases confirm this rating. The Histamine Food List, another commonly used reference, notes that dill in small amounts is “usually not a problem.” That phrasing is slightly more cautious, but it still places dill firmly in the safe zone for most people with histamine intolerance.
The Salicylate Factor Worth Knowing
While dill is low in histamine, it is high in salicylates, which are naturally occurring compounds found in many herbs, spices, fruits, and vegetables. This matters because some people with histamine intolerance also react to salicylates. The two sensitivities overlap more often than you might expect, and the symptoms can look similar: flushing, headaches, nasal congestion, and digestive upset.
Dill appears on most high-salicylate food lists alongside other common cooking herbs like oregano, thyme, rosemary, and cinnamon. If you already know you tolerate those herbs without issues, dill is unlikely to cause problems either. But if you’ve noticed reactions to heavily spiced foods that don’t seem tied to any obvious histamine trigger, salicylate sensitivity is worth exploring with your healthcare provider.
Fresh vs. Dried Dill
Fresh herbs are almost always a safer choice than dried ones on a low-histamine diet, and dill is no exception. Drying and processing can sometimes concentrate compounds or introduce contamination that nudges a food’s tolerability in the wrong direction. Fresh dill straight from the bunch is about as low-risk as a seasoning gets.
That said, dried dill weed (the leafy part) is still generally well tolerated. Dill seed, which has a slightly different and stronger flavor profile, is also rated as compatible on the SIGHI list under mild spices. The practical difference between fresh and dried for most people with histamine intolerance is minimal, so use whichever version your recipe calls for.
Other Low-Histamine Herbs and Spices
If you’re building a low-histamine spice rack, dill fits comfortably alongside several other well-tolerated options. Fresh or powdered garlic, table salt, parsley, chives, basil, and most mild culinary herbs all land in the same safe category on the SIGHI list.
The herbs and spices more likely to cause trouble are those that either contain histamine themselves or act as histamine liberators. Cinnamon, chili powder, cloves, and anise are flagged more frequently on compatibility lists. Premade spice blends can also be unpredictable because they often contain multiple ingredients, some of which may be problematic. Sticking with single herbs you’ve individually confirmed you tolerate gives you the most control.
How to Test Your Own Tolerance
Food lists are helpful starting points, but individual tolerance varies. A food rated as “well tolerated” on a population level can still trigger symptoms in a specific person, especially during a flare or when your overall histamine load is already high. The most reliable approach is to introduce dill on its own, in a small amount, on a day when you’re otherwise eating only foods you know are safe for you. If you have no reaction over the next 24 hours, you can gradually increase the amount in future meals.
Histamine intolerance works like a bucket: it’s the total load that matters, not any single food in isolation. A sprinkle of dill on salmon that’s been sitting in the fridge for three days is a very different situation than fresh dill on freshly cooked rice. The dill itself is low-histamine, but what you pair it with and how fresh those other foods are will shape your overall experience.
