I felt down and just "gray" for no reason at all some days-this works right away with no side effects! These essences are used to address issues with emotional health, soul development, and mind-body connection. You only need to buy one bottle & can make it last for a long time by putting two drops from the original into a separate dropper bottle filled with water/brandy. Don't worry, it doesn't make the remedy "weaker". and it stays just as strong as it's a vibrational medicine. If any information I shared was helpful, please click the 'thumbs up'! Thank you, and happy continued health to you!
