My mom has had hypertension for the last few years and was just recently diagnosed with hashimotos thyroiditis and adrenal fatigue -- with high cortisol. The high cortisol is probably contributing to the hypertension.
Anyway, she had run out of her bp meds and began taking cayenne pepper (in capsules). It brought her bp down. She's back on her bp meds with the cayenne and her bp is now below 140/70! Even with her meds, it never got below 140.
She's taking 2 caps 2x day. I don't know what brand, probably Nature's Way as that's what the local health food store carries. I don't know if she increased the caps or if she went to a hotter cayenne if it would lower it further.
