@COSMOSUNIVERSE If you're looking for dosage here's place to start.

No matter where you start I recommend not taking it on an empty stomach unless you know you can handle it. I've been taking it for years but will never again on an empty stomach when I do it feels like my stomach is trying to eat it's self. I take at least 1 tsp a day. During the winter time maybe as much as 1tbs. I have never gotten a cold while taking Cayenne pepper people around me dropping like flies but I never get sick. If you do buy make sure get the good stuff. I buy in bulk from the Health Ranger store.
