I am now suffering from a stroke. I am always taking this product. Because I can be helpful in cardiovascular diseases they are always taking as usage. So I do not know what I knew was that my blood pressure is lowered is really a little bit. So I recommend people around. I will need more observations. I hope the price is a little lower. Thank you.

My husband had bought this at a vitamin shop and paid more for it. He does not take a lot of supplements as we are on a fixed income but he said this is one that he feels helps with his circulation and I bought it on I herb for him recently. SheriT
