I have taken this specific brand and type of Echinacea for at least 20 years. Whenever, I feel a scratch in my throat or s mild Headache coming on, I reach for Super Echinacea and take it under the tongue, every two-three hours. By morning, no symptoms, no sickness. I have not had a flu or cold since the late 1990's. Echinacea, water and rest, this is my formula for keeping myself well. Be warned--medicine is not supposed to taste like candy and this definitely does not. So take it let it sit under your tongue for a few seconds, swallow, and then drink some water if you must. Stay well
