I buy this product every fall and early winter to boost my immune system and, knock on wood, it has been working. No cold, no flu so far! These two herbs have been used by Native Americans. The goldenseal root has many benefits for the body, especially when mixed with Echinacea. One of the main benefits of Echinacea and goldenseal is that they help to boost the immune system in the body. If you are a person that gets colds quite often or if you suffer from the flu several times throughout the year, you might benefit from Echinacea and goldenseal.
