We offer Essiac Seed Kits with seeds for all four herbs, or buy Sheep sorrel seeds separately! Sheep sorrel and Burdock can be harvested in the first year (although you get more if you wait till year two, if it is Sheep sorrel!) and they are the two primary ingredients in Essiac. They are both easy to grow and a joy to work with.  Burdock should not be allowed to go to seed though in the second year because it might not want to abandon your garden - the burrs are very opportunistic!  Don't be discouraged though -- GROW YOUR ESSIAC HERBS! They may come in handy! It will definitely save you money if you even have a slightly green thumb. In fact, grow some vegetables while you are at it, and maybe some other healing herbs. There is so much in the plant kingdom to keep us well that this is a very good backup plan for these times :) Remember Victory Gardens? you can't lose growing your own!!
