I personally love to grow my own herbs and I think that many of them have great healing properties such as Echinacea. Many doctors frown upon herbs and herbal remedies but I have to wonder if it is because of selfish and money motivated reasons. I think that herbs are amazing if they are used properly and that they have properties modern man-made medicines may not have. Not to mention that many medicines have these herbs in them. They are now saying that this herb may not help your colds but I disagree. I think that this herb could help a cold but many herbs are best at preventing things. I think that herbs and herbal teas and tinctures are best for those preventative methods.
