Review: In a week it is working for me. - In a week it is working for me. Since the last summer I have some Intestinal problems. I didn’t have diahrrea, but now and then loose stool. Changes on the diet resulted with no effect.Tests for pathogene bacteria and parasytes resulted negative. An Upper Endoscopy, a Colonoscopy, and a Capsule endoscopy resulted with negative results too. So the health care system let me go for good, and I was on my OWN. Started oregano oil extract and coconut oil, continued for 4 months with no effects. Last summer I started Olive Leaf Extract Super Strength Standardized for 20% or 150 mg of oleuropein, but two days after I did a big mistake. While taking Olive Leaf Extract, I took Prevnar 13 (Pneumococcal 13-valent Conjugate Vaccine. I never was allergic for anything for all my life, but this time it was different. The next day the injection spot turned read and was eatching. Immediatelly I stopped taking Olive Leaf Extract. The other day the red area enlarget as big as the palm of the hand. The therd day I went to the doctor. He was alarmed and adviced me to go to the hospital. I declined and he used a black marker, starting from the shoulder to the elbow, while I was leaving he told me: if it is going to grow bigger than marked area then go to E.R. In fact it took about 10 days to normlize. I was scared to use Olive Leaf Extract because of this reaction. After health care system let me to go for good, and the loose stool was persistent, I decided to give another try. I started taking Spanish Olive Leaf Extract 25% Oleuropein. The result was imminent. I started Low and slow with 1 Capsule per day. After 3 days I encreased to 2 capsules per day. In a week my intestin is normalised. I plan to encrease to 3 capsules per day for some time, and after go to a maintenance dose 2 capsules per day. Based on my opinion the Olive Leaf Extract is very potent. It can create strong alergic reactions with vacines, and the human body tolerates it well. If used for treatment of different medical condition Start Low and slow but to have effect you must reach a lethal dosage for the pathogen and stay in this level for a while before going down to a maintenance dose. The ability of cancer and pathogens to evolve, and adapt is a principal challenge to therapy in general and to the paradigm of targeted therapy in particular. This ability is fueled by the co-existence of multiple, genetically heterogeneous subpopulations within the cancer and pathogens cell population. Increasing evidence has supported the idea that these subpopulations are selected in a Darwinian fashion, by which the genetic landscape of the tumor or infection is continuously reshaped. This may happen while using semi lethal doses for the pathogen.
Review: It Works! - Wow! 3 weeks ago my bp was 188/100. I suffer from white coat syndrome and my bp soars if I am anxious, therefore I'm not a candidate for bp meds , as when I'm not stressed my bp plummets dangerously low. I read about olive leaf extract and got the green light from my doctor to take it. It's been 3 weeks since that high reading. I have also begun lowering my sodium and caffeine consumption and increasing my postassium-rich food consumption. I have also adopted the 4,7, 8 breathing meditation. All of these things worked together very well for me. The olive leaf extract made a huge difference. I even bought some for my sister and she is seeing remarkable reduction in her bp readings. The seller contacted me and advised me to start slow with the dosage , as their brand is more potent than most. I thought that was very kind of them. I will not be without my olive leaf extract. It has so many antimicrobial and antifungal benefits, and even helps lower glucose levels in addition to lowering bp. I purchased some earplugs from desertcart to take with me to the doctor to help drown out the bp machine sound that bothers me. The lower readings from the olive leaf has helped me not be so anxious about taking my bp so eventually the earplugs may not be necessary.

## Features

- 40% POLYPHENOLS — Super-strength 500mg Per Capsule (not “per serving”) of olive leaf extract. All 500mg is standardized to at least 25% pure oleuropein and 40% total olive polyphenols.

- PREMIUM SOURCE — Harvested on family-run Spanish olive farms. Processed in Spain using traditional extraction (no chemicals). Made by Island Nutrition, maker of premium supplements since 1995.
