celery seed extract lowers blood pressure and cholesterol

You know it very well as a vegetable. But you may never have thought of it as a powerful healing herb. Though its long tradition as a blood pressure herb has attracted little attention, science is finally beginning to take note.

Celery seed has a long tradition as a herb for high blood pressure. In traditional Chinese medicine, celery has long been recommended for lowering blood pressure.

Modern science pretty much ignored celery until a preliminary 2013 study showed that 150mg a day of celery seed extract, standardized for 85% 3-n-butylphthalide, can significantly lower blood pressure in people with mild to moderate high blood pressure (Natural Medicine Journal 2013;4(4):1-3).

It took almost a decade to follow that lead up. This year, researchers conducted a triple-blind, placebo-controlled study of celery seed extract. The study gave 52 people with high blood pressure either a placebo or 1.34g of celery seed extract a day for 4 weeks. The celery seed extract significantly lowered both systolic and diastolic blood pressure (Phytother Res. 2022 Jul;36(7):2889-2907.

The same group of researchers has published a second study. Also triple-blind, this study included 51 people with high blood pressure. The study lasted 4 weeks, and the dose was again 1.34g a day of celery seed extract.

Once again, while blood pressure did not change in the placebo group, systolic and diastolic blood pressure both went down significantly in the celery seed group. As a bonus, fasting blood sugar, triglycerides, total cholesterol, LDL cholestero and HDL cholesterol all improved significantly in the celery seed group as did measures of liver and kidney function.

Interestingly, perhaps because it worked so well, celery seed extract also significantly improved sleep quality by night and sense of relaxation and freshness by day. It led to significantly better breathing and less dizziness.

And a bonus: celery seed extract was safe with no adverse events.

So, take note. Celery seed extract may be an safe, inexpensive and important addition to your blood pressure program.
