From the Research
Celery seed can act as a mild blood thinner, and its use may increase the risk of bleeding when combined with anticoagulant medications. The most recent and highest quality study, 1, published in 2022, investigated the antihypertensive effects of celery seed extract and found that it can lower blood pressure in patients with hypertension. While this study did not directly examine the blood-thinning effects of celery seed, it suggests that celery seed extract may have a beneficial effect on cardiovascular health.
Other studies, such as 2 and 3, have also explored the potential health benefits of celery seed, including its anti-inflammatory and antimicrobial properties. However, the study by 1 is the most recent and relevant to the question of whether celery seed is a blood thinner.
It is essential to note that people taking blood thinners, those with bleeding disorders, or individuals scheduled for surgery should consult their healthcare provider before using celery seed supplements, as the blood-thinning effects of celery seed may increase the risk of bleeding. Additionally, the blood-thinning effects are typically more pronounced with concentrated supplements rather than the small amounts used in cooking. If you experience unusual bruising or bleeding while using celery seed, discontinue use and seek medical attention.
Some studies, such as 4 and 5, have investigated the toxicological effects of celery seed extract and its potential to interact with other medications. However, the study by 1 provides the most relevant and up-to-date information on the potential health benefits and risks of using celery seed as a blood thinner.
In summary, while celery seed may have potential health benefits, its use as a blood thinner should be approached with caution, and individuals should consult their healthcare provider before using celery seed supplements, especially if they are taking anticoagulant medications or have a history of bleeding disorders.
