I have several books on herbs and their uses. I find it fascinating. Years ago, when I had a lavender patch, I made lavender wands to place in linen cabinets, drawers etc. You pick an odd number of lavender sprigs, gather them together, place a ribbon just below the heads, knot it, then bend the stems back over the flower heads and weave a "basket" over the heads with the ribbon, when done, tie a pretty little bow with the remaining ribbon and let dry. I also learned that it was best to cross check any recipe with other books as sometimes one book would recommend a particular herb for one thing and then another book would describe the same plant as poisonous. Harvesting herbs for ingestion can be tricky as the potency of the active ingredient depends a lot on the growing conditions and the point at which you harvest the herb as well as how you handle and store the plant after picking.
