I'm growing my own "headache cure." What do we usually do when we have a headache? Most people take an aspirin and lie down to relieve stress. American Indians did something very similar, only they would just lie down in an Aspen grove and be lulled into a sweet reverie by the gentle rustling of the Aspen leaves from a soft breeze on a summer day.
My daughter and I used to hike in the woods and find an Aspen grove for a brief rest. We were soon refreshed and on our way. The family of trees is salicaceae including Aspen, Willow, and Poplar, giving salicylic acid. This eases pain. Do you see any similarity in the words aspirin and Aspen?
