The flame never reaches the herb thus does not burn it. Breathing hot smoke is what f's up your lungs. Vaporizing heats it slowly like a crock pot for pot and thus only provides white cool smoke which is actually good for the lungs.

The heat will be isolated to the bottom of jar so touching the sides is no problem.
