A popular spice used in curries and stews could help lower the risk of serious health conditions. According to several studies, coriander seeds may aid in reducing cholesterol and blood pressure levels, potentially decreasing the risk of heart disease, heart attack, and stroke.
One study published in Current Cardiology Reviews found that coriander seeds have a remarkable hypolipidemic action, significantly decreasing total cholesterol and triglycerides in animal tissues. The levels of low-density lipoprotein (LDL) and very low-density lipoprotein decreased, while high-density lipoprotein (HDL) increased in the experimental group compared to the control group.
Another trial from the Journal of Environmental Biology in 2008 fed coriander seeds to rats and observed lower levels of LDL and higher levels of HDL in the group that consumed the seeds. The study noted that the levels of LDL and very low-density lipoprotein cholesterol decreased, while HDL increased.
Additionally, a 2009 report in the Journal of Ethnopharmacology concluded that coriander fruit could successfully lower blood pressure, or hypertension. The paper indicated that the fruit exhibits gut stimulatory, inhibitory, and hypotensive effects, possibly mediated through cholinergic and calcium antagonist mechanisms, with diuretic activity adding value in hypertension treatment.
A healthy total cholesterol level is five or less millimoles per litre (mmol/l), with HDL at one or more mmol/l and LDL at four or less mmol/l. Blood tests from a doctor can determine cholesterol levels, while blood pressure can be checked at home or by a pharmacist or GP. Coriander seeds can be used whole or ground, and the plant is also popular as a herb.
