Recently I had a mild sore throat that persisted for 21 straight days with no change in intensity. So I tried an herbal throat spray by St. Francis Herb Farm called “Stop it Cold.” I was going to buy another brand that was cheaper until I read the ingredients. I chose the St. Francis brand, as it included a different species of Echinacea – Echinacea angustifolia, which is the powerhouse of Echinaceas. My sore throat was about 60% better in one day, and gone in 48 hours. A noteworthy product.
