I posted in the original thread but I wanted to include the information here as well. According to research, one hour twice a day was effective for successful treatment. I'll have to do some more back tracking through my notes, but I recall that doing this for 2 months was the duration of treatment.

"There are historical precedents for the successful treatment of lung infections by garlic preparations. Thus, Minchin [21] used a specially designed mask to treat tuberculosis patients twice daily by one-hour inhalation periods with crushed garlic preparations containing ‘oleum allii’. Minchin also reported using oleum allii inhalation prophylactically “in the homes of, and by the members of, families notably affected by pulmonary tuberculosis”. These pioneering studies dropped out of focus as streptomycin, without the unpleasant smell of allicin, was introduced in 1944 and used as a treatment for tuberculosis."
