We are often asked how come 400 mg of echinacea can be purchased for so much less than 250 mg? Is there a mistake? Is the blend that special? No! Product #978 is a 1:1 extract powder, meaning it took one kilogram of raw material to make one kilogram of extract powder. Everything you started with is present, marc and all. It is NOT standardized. The source of the echinacea is "Echinacea Purpurea."

On the other hand product #990 is standardized to 4.0% phenolic compound. Typically this product is about a 4:1 extract powder. Therefore, some of the marc is tossed and some is used as the carrier. Because if you start with about 4 kilograms and end up with one, something had to be thrown away. This sums up the fact that #990 is more concentrated than #978. The source of the echinacea for this product is a combination of "Echinacea Purpurea and Echinacea Angustifolia," hence the name "Echinacea Blend." There are some herbalists who believe a combination of the two species will provide additional benefits. Both species have numerous journal articles to their credit.

Some individuals use #978 as a day to day immune support nutritional supplement. While #990 can be used more acutely because it is stronger or by those individuals who feel additional support is needed.
