HelloPharmacist Scorecard of Celery Seed Extract by Nature's Answer
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. The supplement also includes inactive ingredients — water, purified glycerin, and alcohol — which serve as the liquid base and preservative.
Does it work?
Couldn't assess
The evidence on celery seed extract for the conditions listed here — sexual dysfunction, anxiety, headache, depression, diabetes, and indigestion — is insufficient to establish it works. We have no reliable data supporting its use for any of those purposes.
How safe is it?
Well-documented data
Celery is generally well tolerated when taken orally. The most common side effect is photosensitivity — increased sun sensitivity that can lead to skin reactions if you're exposed to bright light.
Some people develop oral allergy syndrome (itching and burning in the mouth and throat), and in rare cases, people with celery allergy have experienced anaphylaxis (a severe allergic reaction). During pregnancy, medicinal amounts of celery seed should be avoided because it may affect the uterus; food amounts are likely fine.
For breastfeeding, there isn't enough reliable information, so it's best avoided. If you have a known celery allergy or oral allergy syndrome, this product isn't for you.
Meds to double-check
Moderate interaction found
Before you start, double-check with us or your pharmacist if you take blood thinners (anticoagulants or antiplatelet drugs), venlafaxine (Effexor) or other antidepressants, levothyroxine (Synthroid) for thyroid function, lithium for mood disorders, blood pressure medications, or acetaminophen regularly. Also flag any drugs that make you sun-sensitive.
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.
This product is best suited for people with no allergies to celery and no prescription medications — especially blood thinners, antidepressants, thyroid drugs, or blood pressure medications. If you take any of those, or if you have a history of allergic reactions to celery or related plants, talk to your pharmacist before starting.
Pregnant and breastfeeding people should also check with their pharmacist or doctor first.

Celery Seed Extract by Nature's Answer Drug Interactions
HelloPharmacist Interaction Report
Nature's Answer Celery Seed Extract contains one active ingredient — celery seed extract — and it does interact with a number of medications.
The most serious concern is with blood thinners (anticoagulants and antiplatelet drugs). Celery contains compounds that may reduce platelet clumping, which could increase 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 confirmed in humans yet.
Read the full breakdown — every affected drug type, severity by severity
Celery also interacts with several other drug types. It may increase blood levels of venlafaxine (Effexor), a type of antidepressant — one case report describes mood symptoms after combining them.
It theoretically affects how your liver processes drugs metabolized by CYP1A2 (a moderate concern), and may reduce the effects of levothyroxine (Synthroid) for thyroid hormone replacement. If you take lithium for mood, celery's diuretic properties might raise lithium levels to unsafe concentrations.
It could also add to the blood-pressure-lowering effect of antihypertensive medications, and may prolong the action of acetaminophen (Tylenol). Finally, because celery contains light-sensitizing compounds, it might increase photosensitivity if you're on certain drugs that cause sun sensitivity.
Altogether, these interactions span 651 individual medications. If you take any prescription medication — especially blood thinners, psychiatric medications, thyroid replacement, or blood pressure drugs — use the medication checker below before starting this product.

For each ingredient in Celery Seed 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.
