What's this test for?

This test is ideal if you're experiencing unexplained digestive upset, skin reactions, congestion, or fatigue that seem to flare up after eating certain plants or being around specific foliage. Sheep sorrel is a common weed found in many foods, herbal teas, and supplements, and some people react to it without realizing it. This test helps you figure out if sheep sorrel sensitivity could be behind your symptoms.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what a normal versus elevated IgG4 level to sheep sorrel means. If your level comes back high, a simple next step is to reduce or eliminate sheep sorrel from your diet and any herbal products for a few weeks and see if your symptoms improve. You can download a standard lab report from your account at any time, and if you retest later, the trends feature lets you track how your levels change over time.

Who should consider this test?

This test is a good fit for anyone who eats a lot of leafy greens, wild foods, or herbal supplements and notices recurring bloating, hives, headaches, or fatigue without a clear cause. It's also useful for people who have already ruled out more common food triggers and want to check less obvious plant exposures. If symptoms show up after gardening, hiking, or eating foraged greens, this test can add helpful information.

What symptoms indicate I may need this test?

Common signs include stomach cramps, bloating, diarrhea, skin rashes or itching, and nasal congestion that happen after eating leafy greens or using herbal remedies. Some people also notice fatigue or brain fog that doesn't have an obvious cause. If these symptoms keep coming back and you can't pin down why, checking for a sheep sorrel sensitivity is a reasonable step.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once processed, they'll be posted directly to your online account, and you'll be able to view and download the full report from there.

How can I naturally support my body if I have a sheep sorrel sensitivity?

Start by removing sheep sorrel and related foods (like dock leaves or certain herbal teas) from your diet for a few weeks to see if symptoms ease up. Supporting your gut with fiber-rich whole foods and probiotics can help calm overall inflammation. Staying hydrated and reducing processed foods can also make it easier for your body to recover from food-related reactions.

What does a high sheep sorrel IgG4 result mean?

A high result means your immune system has built up extra antibodies in response to sheep sorrel exposure, which for some people is linked to ongoing mild symptoms like bloating or skin irritation. It doesn't necessarily mean a severe allergy, but it does suggest your body is reacting to this plant more than typical. Cutting back on exposure and watching how you feel is a practical way to see if it's connected to your symptoms.

What causes a high IgG4 reaction to sheep sorrel?

Frequent or repeated exposure to sheep sorrel through diet, herbal teas, or supplements can cause your immune system to build up antibodies over time. Eating a diet heavy in foraged greens or certain detox teas that include sheep sorrel is a common source. Gut health issues that make your digestive lining more permeable can also make these reactions more likely.

How often should I retest?

If you make dietary changes based on your results, retesting after 8-12 weeks can show whether your levels have gone down. For general monitoring without symptoms, retesting once a year is a reasonable cadence. If symptoms return after you reintroduce sheep sorrel, that's a good time to retest sooner.

What should I do if my results are abnormal?

If your result is high, try removing sheep sorrel and related products from your diet for several weeks and keep a simple symptom journal. Watch for improvement in digestion, skin, or energy levels during that time. If symptoms are severe or don't improve, seek medical care to rule out other causes.
