hi thanks for input, i did post this to humaworm also so will see what they say. i dont run but i never sit down lol looking after two children and i am not over weight i have had an echocardiogram my heart is fine, had kidney function tests-the lot all of which were fine which is why i asked if the herbs could be making my bp low or if they have done such a good job of cleansing my system that i have a heart of an athlete? or so my doctor keeps telling me!! i am a worrier yes and i am anxious but was just curious and wondered if it may have been the herbs that lowered my bp and heart rate . thanks
