Other studies also support sesame oil’s role in reducing blood pressure. In a 2006 pilot study published in the Journal of Medicinal Food, the authors looked at the effect of sesame oil in hypertensive diabetics medicated with atenolol (β-blocker) and glibenclamide (sulfonylurea). They found that when sesame oil was used as the participants’ only source of edible oil, it lowered blood pressure beyond what was achieved with just medication. The authors speculated that sesame oils’ antihypertensive effect might be due to the lignans found in it — such as sesamin, episesamin, sesamol, and sesamolin — as well as its rich vitamin E content and unsaturated fatty acids.
Additionally, a 2012 study in the Journal of Clinical Hypertension showed that in hypertensive men, sesame oil reduced blood pressure both in the short and long term. They stated that even 35 grams was capable of causing acute effects on blood pressure.
A later 2016 study published in the Journal of Clinical Lipidology further found that combining sesame oil with rice bran oil also lowered blood pressure. Additionally, it improved people’s lipids.
