Some dont know this But with all herbs , tinktures, Salts ,dewormers, oregano , etc etc. To keep them potent Keep them in the dark. With my products from MH I make sure to protect them from any light. Hope this helps. even the juice i carry around with oregano drops in it , i try to keep it in "the shade"
Herbs and herbal formulas are put in the dark amber/blue bottles to keep them safe from alterations from the sun. :) Regardless, I still like to keep my herbal tinctures in the shade, too <3.
The sun is the supreme power and it will suck the life out of anything if there is not a natural protection and that is why it is a good idea to keep all herbs out of the sunlight after they have been processed.
