From your treatment bottle take four drops four times a day or more often. Simply put the drops directly into the mouth (be careful not to touch dropper to your mouth), or add to any beverage. There is no chance of over-dosing as this is the vibrational energy of the healing plants. What is most important is frequent exposure to the healing vibration. The mixture expires in three weeks because the water which may have been contaminated has expired. The vibration is still active.
