I have taken 1g olive leaf extract /day for 25 years. I have genetic high blood pressure (totally broken ACE gene). OLE is an ace inhibitor and I can feel it relax my blood vessels. It is such a relief that I will never be without it. I have stage 3 hypertension...it takes my b.p. down significantly - in the literature 11 points. However I need other means to lower it at least another 20 points (I used cal mag citrate, and DHEA to keep the cal mag in my system, otherwise I lose it in about 2 hours). In ADDITION, I have to eat a low salt diet (my b.p. is pretty high w/o these steps).
I got on here to find out if anyone with POTS has tried it because OLE also lowers your heart rate to 60 beats / min. It does not cause any kerthunkin for me!
I take rhodiola and, back in the day when it first became available here, it was a high dose (perhaps before perhaps dosage was known?) and it used to cause one delayed kerthunk heartbeat when I first laid down. Becuase of this, I only used this when I needed it for stress due to adrenal exhaustion. When I started taking OLE, that took care of the kerthunk delayed beat. So I take rhodiola all the time now. However, I am unsure if the dose is as high as in those early days.
It's interesting that JES thinks it reduces stomach acid. I have had reduced HCL for a long time. I have to drink kombucha or ACV for acid, take extra zinc, digestive enzymes,... I will have to look into OLE as the source. However... the OLE is keeping me alive so I wont ever stop taking it. Prescription ACE inhibitors make me feel like I can't think and have a foot in the grave. However they work is not the way my body can deal with.
