Well, if Id continued to go by Andy's yellow book Id still be really sick with Hg poisoning. From my experience he's been wrong about allot of things. I don't think you can get more effective than an IV, you're shooting it into your arm. I would imagine that taking it by mouth is as none effectual as suppositories are. I got some good benefits from trans dermal. I used to put it around my ankles after I figured out that if the mosquitoes think that's a good place to bite me it must be a good place to try.

Regards.

Rachel?
