HelloPharmacist Scorecard of Celery Seed Liquid Extract by Swanson Premium Brand
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: celery seed extract. Swanson has formulated it as a liquid for easier dosing.
The inactive ingredients are purified water, vegetable glycerin, and certified organic alcohol — the last two help preserve and deliver the extract.
Does it work?
Couldn't assess
The effectiveness data for celery seed extract in our files is limited. The evidence is currently insufficient to rate it for sexual dysfunction, anxiety, headache, depression, diabetes, or indigestion — meaning the research either isn't robust enough yet or isn't there.
One piece of solid research does show that celery seed extract can reduce daytime systolic blood pressure by roughly 12 mmHg compared to placebo, but we don't have effectiveness ratings for other common uses.
How safe is it?
Well-documented data
Celery seed extract is generally well tolerated when taken by mouth. The most common side effects are photosensitivity (sun sensitivity) and oral allergy syndrome — itching and burning in the mouth and throat — in people who are sensitive to celery.
Rare but serious allergic reactions including anaphylaxis have been reported. During pregnancy, medicinal amounts of celery seed should be avoided because it may affect the uterus; food amounts are likely safe.
For breastfeeding, there isn't enough reliable information, so it's best to skip supplemental celery while nursing. Anyone with a known celery allergy should not take this product.
Meds to double-check
Moderate interaction found
Before taking this product, double-check if you're on any blood thinners (like warfarin or aspirin), thyroid medication (levothyroxine), the antidepressant venlafaxine (Effexor), blood pressure medications, or lithium — these carry Moderate-severity concerns. Also mention any photosensitizing drugs you take.
If you take any medication metabolized by CYP1A2, run it through the checker on this page.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
If you're looking for a blood pressure support supplement, celery seed extract shows promise — but it's not a substitute for blood pressure medication and it interacts with several drug classes. Anyone on blood thinners, thyroid medication, antidepressants, blood pressure drugs, or lithium should check with their pharmacist first.
People with celery allergies should avoid it entirely.

Celery Seed Liquid Extract by Swanson Premium Brand Drug Interactions
HelloPharmacist Interaction Report
Swanson Premium Brand Celery Seed Liquid Extract interacts with a number of medications.
The most serious concern is with blood thinners (anticoagulant and antiplatelet drugs) — celery contains compounds that may slow blood clotting in the lab, which could theoretically raise your bleeding risk if you're already on a blood thinner like warfarin or aspirin. This is a Moderate-severity interaction, though it hasn't been seen in actual patients yet.
Read the full breakdown — every affected drug type, severity by severity
Several other drug types also carry Moderate-severity concerns. If you take thyroid medication (levothyroxine/Synthroid), celery seed might reduce how well it works — there are case reports of people whose thyroid symptoms came back after starting celery seed supplements.
The product may also increase blood levels of the antidepressant venlafaxine (Effexor), potentially causing side effects; one case report documented this when taken alongside other supplements. Celery seed can lower blood pressure on its own, so combining it with blood pressure medications might cause your pressure to drop too far.
Additionally, it may theoretically raise levels of certain drugs your liver breaks down using the CYP1A2 enzyme, and it could increase lithium levels by reducing how your kidneys clear it. Finally, a Minor interaction exists with photosensitizing drugs — celery contains compounds that may increase sun sensitivity.
Altogether, these interactions span 651 individual medications. Check your exact prescriptions with the search tool on this page before you start.

For each ingredient in Celery Seed Liquid Extract with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Celery seed extract
Anticoagulant/Antiplatelet Drugs
Theoretically, celery root might increase the risk of bleeding when taken with anticoagulant/antiplatelet drugs.
Celery root contains the constituents falcarinol and falcarindiol. Laboratory research suggests that these constituents can inhibit platelet aggregation. This effect has not been reported in humans.
Antihypertensive Drugs
Theoretically, celery seed extract might have additive effects with antihypertensive drugs.
Clinical research suggests that taking celery seed extract may reduce daytime systolic blood pressure by about 12 mmHg compared to less than 1 mmHg with placebo.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, celery might increase levels of drugs metabolized by CYP1A2.
In vitro and animal research suggests that constituents of celery can inhibit CYP1A2. This effect has not been reported in humans.
Levothyroxine (Synthroid, Others)
Theoretically, celery seed might decrease the effects of levothyroxine.
Several cases of hypothyroidism with low T4 levels have been reported in people who were previously stabilized on levothyroxine and then started taking celery seed tablets. They presented with symptoms such as lethargy, bloating, and dry skin, and recovered when celery seed was stopped. However, celery stem and leaf has been associated with case reports of hyperthyroidism in patients with no pre-existing thyroid disorders.
Lithium
Theoretically, celery might reduce excretion and increase levels of lithium due to potential diuretic effects.
Celery is thought to have diuretic properties. However, this effect has not been confirmed in humans.
Venlafaxine (Effexor)
Theoretically, celery root extract might increase blood levels of venlafaxine.
There is one case report of a patient who experienced medication-induced bipolar disorder after beginning to take celery root extract 1000 mg daily along with venlafaxine 75 mg and St. John's wort 600 mg daily. Symptoms included confusion, speech abnormalities, manic affect, and visual hallucinations. The plasma level of venlafaxine was 476.8 ng/mL (normal range 195-400 ng/mL). It is theorized that celery root increased venlafaxine levels by inhibiting cytochrome P450 2D6.
Acetaminophen (Tylenol, Others)
Theoretically, celery juice might increase the effects and side effects of acetaminophen.
Animal research suggests that concomitant use of celery juice plus acetaminophen prolongs the effects of acetaminophen. This effect has been attributed to a decrease in hepatic cytochrome P450 activity. However, other animal research shows that pretreatment with celery root extract protects against acetaminophen-induced acute liver failure. These effects have not been reported in humans.
Photosensitizing Drugs
Theoretically, celery might increase the risk of photosensitivity reactions when taken with photosensitizing drugs.
Laboratory research shows that celery contains photosensitizing agents such as phenols and psoralens.
