Can Eating Cayenne Pepper Decrease Blood Pressure and Unclog Arteries?

Like turmeric, cayenne pepper has become a staple cure-all spice in many kitchens. While this ingredient can add a kick to any dish and provides some anti-inflammatory effects, the benefits of cayenne pepper are not exactly magic. Although you may have heard that cayenne pepper can help unclog arteries or decrease blood pressure, science has yet to confirm this rumor.

Can Cayenne Pepper Unclog Arteries?

Cayenne pepper contains capsaicin, which is responsible for the pepper's undeniable spice, according to the University of Michigan. Often, capsaicin is used topically in cream or lotion form to help relieve pain.

Capsaicin has also been praised for its ability to unclog arteries and lower blood pressure. However, even the little research supporting these claims only saw results in animal test subjects. So while some findings (like this Ausgust 2010 study published in Cell Metabolism conducted on mice) may show an association between capsaicin and decreased blood pressure in animals, these results have not been replicated in humans.

Health Benefits of Cayenne Pepper

Cayenne pepper may not definitively be able to unclog arteries or lower blood pressure — but it may have some digestive benefits worth considering. Capsaicin may be able to stimulate digestion and regulate build up of digestive fluids, according to a January 2016 review published in the Journal of Complementary and Integrative Medicine.

Cayenne pepper has also been long used as a natural anti-inflammatory, according to a March 2018 study published in the European Journal of Translational Myology. When applied topically, cayenne pepper-based treatments has been shown to relieve cramps or muscle pain.

The capsaicin in cayenne pepper may also be used in weight loss. Consuming cayenne pepper can help boost feelings of satiety and curb hunger, according to a June 2014 study published in Appetite. When eaten after dinner, capsaicin can help prevent overeating, the study found. So why not spike some freshly squeezed lemonade with cayenne after dinner?
