Is homeopathy placebo?

Common placebos include inert tablets (like sugar pills), inert injections (like saline), sham surgery, and other procedures.
Is nitrogen an inert gas?
Note that nitrogen is not truly an inert gas. It is usually delivered at dew point between -75°F and –110°F and mixed with hydrogen in a 90/10 blend. A new guideline for the use of hydrogen blended gas to be inert is 3% or less. An atmosphere of N2 can be used for the following heat treatment processes:
Is helium an inert gas?
In general, argon and helium are more inert than hydrogen. A pure nitrogen atmosphere provides blanketing of the part being heat treated and can be used to purge the existing atmosphere or be used as a carrier gas for carbon-controlled atmospheres. Note that nitrogen is not truly an inert gas.
