I read a great article at WebMD.com where a Dr. was sly and got the U.S. government to allow research on herb as the Dr. was trying to establish a link between herb and the tollerance system. He studied AIDS patiences that used herb. The way the government studied it was really messed up in a way where it would point to herb being bad for your tollerance system.

The Dr. found no link to herb and any lowering of the tolerance system. Use the herb to help you feel better.... Eat it or vaporize it if you have a sore throat... Get well soon!
