The only thing I knew about cucumbers that's on that list is they are mostly water. I buy them for internal hydration.I saw this on FB so take with a grain of salt. But another plus if it's true for tortoises too
My take on that is, if you are dehydrated, your blood pressure can drop. I fight dehydration a lot. In fact this morning my pressure was very low. AC also can dehydrate. I drink liquid IV whenever I feel dehydrated and it helps quickly, then drink something all day long.I do wonder what "Hydrate blood pressure" means
