Yo Lauren,I aways use Echinacea when i get rough,I'm not really into herbal stuff at all but i was told this was really good stuff and tryed it and sure enough it done the trick sis.Some people take 1 a day all the time but i just slam 3 into me when i feel a cold or something else coming on!Get well soon chick
P.S i have'nt had a cold in about 18months;)
