I don't think he's kidding
For those who know about lyme and check for ticks when they have been anywhere they may hang out
and for those who develop a circular rash at the site of a tick bite, which presumably is the immune systems attempt to contain the infection,
surely it would do no harm to apply Miracle-Mineral-Supplement to the area if it's on hand maybe with DMSO for better penetration.
One thing I do know is that ticks stay attached for a period and you can catch them at it and disinfect the area just in case, so the chances are if anything has got in, Miracle-Mineral-Supplement may be a very good way of stopping it
