Fire Cider has been used in naturopathy practice to ward off common viruses like cold and flu. The best way to use this potent oxymel is to throw back a shot at your first sign of becoming unwell. Fire cider can help boost immunity response, relieve nasal congestion, support digestion and it give my husband and I a huge energy boost. As I am sure you can tell, this product packs a punch but thats a small price to pay if you can avoid illness and keep life moving.
