Although I've had good luck using jin shin jyutsu and shiatsu for clearing up colds and flus when they're just beginning, I've never had any success in significantly affecting a full-blown case of flu, even though I've several times worked with a jin shin flow which is specifically supposed to clear up colds or flu when the person is already in the middle of a full-blown case. This time, I added QT to my shiatsu & jin shin techniques, and my son went from rating his flu symptoms (fever, exhaustion, red eyes, achy joints, congestion) a 10 to rating them a 2. The next morning, though in vastly better shape than pre-treatment, he was back up to what he rated as a 5. I worked another hour on him and he was good to go! I was afraid he might undo our good work what with racing off to his activities, but he's been fine ever since.
