When I was little, my older brother and I used to cut weeds with sticks all the time, and this white juice would ooze from the broken stems. One day I cut myself outside playing, and he told me that weed juice would make it heal faster and take the pain away. The placebo worked, and I believed this until I was 11. Before then, I managed to pass the 'secret' on to my friends, who believed it and told their friends, and so on. Who knows where this is now...
