There is all kinds of organic herbs to help us feel good about our well-being. It does not necessary have to be drugs. There are quite a number of herbs out there that can actually help us de-stress, and plants that possess healing properties.
If you visit www.iamshaman.com, you would be surprised by the list of plants that some of them we sees as grass and weeds are actually "healing" plants.
