There is no standard echinacea dosage. Since the supplement has not been studied in dose-range studies (these studies are rarely performed with herbal supplements), only vague "trial and error" information is available for the product. Some echinacea products contain significantly less echinacea than labeled, and different products may contain different species of echinacea, so it is difficult to establish a standard safe and effective dose. It is probably reasonable to follow the dosing instructions on your particular echinacea product.
