Echinacea has been a common “cure” for the common cold in the United States since at least the 19th century. Since it is indigenous to North America, it was first used by Native Americans to treat anything from wounds to snake bites. Early settlers learned of its efficacy and it became a common tonic for colds, and bites and all kinds of ailments as well. Sometime during the mid 20th century, Germany caught on to the wonders of Echinacea and began using it as well. It is said that medical professionals in Germany today use it at least one million times annually to treat respiratory infections and colds. It can effectively treat viral as well as bacterial infections if taken at the first sign of malady.
Actually it is the root of the plant that is used in supplements today. The plant needs to flower first, and the roots are then cleaned and dried, and crushed for use in supplements, tonics and tinctures. Sometimes parts of the blossom are used with the roots to brew as a soothing, restorative tea. Echinacea tea is especially beneficial if sweetened with honey and lemon if it is being used to treat a cold or flu.
When taken as a supplement, depending on its intended use, the dosages range from 200mg to 1000mg up to three times daily. There have been no reports of adverse or negative side effects. You can buy Echinacea supplements and tea online as well as in local health food stores. I prefer to get mine shipped directly from manufacturers because I want to ensure the freshness and viability of the product I use. Even though it stores well when dried, I want to know that I am getting a pure, fresh product.
