With only a few common tools and a few simple ingredients, which are available at most any herb shop or natural foods store, you can open your own phyto-pharmacy. And while it's arguably much easier and a lot less messy to buy your remedies ready-made, many people find that the do-it-yourself, get-your-hands-dirty approach is both rewarding and effective. By making your own remedies, you can control more aspects of the product you're using, and you'll gain a greater understanding of the power of plants.
