Magnetism has been peddled as a miracle cure for decades. Some others: Psychic surgery; "mystics" who insist that "enlightened DNA" can have a quadruple/quintuple/sextuple/etc. helix; astrologers who claim that gravity & other forces from various celestial bodies are responsible for the zodiac personalities; the radiation "wellfullness" devices from the first half of the 20th century; and many more.
This reminds me of how DNA spirals that "twist the other way" was a plot point in Strange Days At Blake Holsey High.
