Avoid fluoride at all costs, I didn't know calcium calcifies the third eye, lemons (for their citric acid) and garlic are good detoxers (just make sure to minimize the garlic so your breath doesn't get in the way of your social life), and filter your water before drinking it so it doesn't have any fluoride, chlorine, or anything else that can calcify your third eye (lemonade could work). This is my advice on decalcifying the pineal gland.
