to my best knowledge;
out of the fridge you HAVE to add Oregano-oil,
to prevent spoilage & molds
and I would add O-oil regardless of tempertures
as Oregano-oil adds its own very beneficial powers
to our health.
If its MH-Oregano----1drop in 1 quart for a week,
than up it by another one 2e week.
Uptill?you feel its beneficial to you
