Try to find a store that sells seeds. They usually have Wormwood and cloves. Cloves can usually be bought at regular food stores also. The Black-Walnut is harder..Try calling around to the health food stores with the largest variety of herbs and ask them for it, they will not have it in the store, but if you speak to the owner of a health food store like that, that person will probably be able to order it for you from another company. If they don't have it, go on the internet to find producers close to you and explain you situation, or ask a foreign company if you can send them a money order instead of cc for the walnut tincture. You must use it as a tincture, unless you happen to ripe it in September at home :-). There are companies selling it as a regular herb the year around..to unknowing customers..You can use a mortel to prepare the Wormwood to make it easier to eat, if you can't get a hold of gelatin capsules, unless you decide to do a tincture.
