Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
I did not realize that, until I received the product, that they recommend taking SEVEN pills a day! That is a lot of pills, and considering that you get only 100, it barely lasts 2 weeks! I think it is a ripoff & wil not buy again.
I use echinacea to boost my immune system during the winter when I spend more time indoors than I would like due to the cold weather. Glad it is still readily available through Amazon since it is not always available in stores at a reasonable price.
