My eighty-something in-laws were telling me about Filipino folk healing from the old days (meaning up into the 1970s, at least). The most curious story I heard was about this fellow they knew who would feel his patient's pulse, and then declare whom he had to go to to be cured. Now, this third-party was generally not a healer, and had never done this kind of thing before. But you brought the healer-designee seven grains of rice, he chewed them, placed them on your neck, and, bing-botta-bing, you're healed! I guess the bloke who told you whom to go see was kind of like the gateway provider in an HMO.
Less impressive was the story of the woman who could make someone sick just by looking at them. I said that's nothing -- I've made a whole room-full of people sick just by talking to them, and a whole discussion-list of people sick with my posts.
