I put those golden flowers in olive oil that I rub on bruises and sprains. The leaf and flower I actually use in tea/tincture form for colds and flus particularly since it is great for slowing down/stopping the drippy nose thing. Most interesting for me is that ragweed before it blooms and sends out its pollen is one of best herbal antihistamines I know!! Who knew the cure for pollen was actually the plant!! Nature is so accommodating...
