I tell you what, if you can gag it down it works like a champ. My mother-in-law, who’s kinda hippy dippy, gave me some and made me take it when I had a cold – cut my cold in half. Took it last year during cold season and I was only sick one day. Taking it right now for a cold I started feeling Monday morning and it’s drying me up. I do 5 drops 3x a day in a glass of orange juice. Stuff tastes like battery acid but it works.
