I don't think it can, I know it can. Through affirmation. Use of the herb. And scientific documents online that says it can kill a virus and many other diseases and, many herbs contain many different natural medicines that will heal you. Thank you. Even people thousands of years ago knew this, through affirmation. Get a grip on reality please. I bet if I told you that, chi was real, and it is. You say the Same bullshit. It is real, you can physically use it. I've physically used it many times. Chi, energy. Energy Is part of physical chemistry. So suck it ;)
