Make sure you have a good quality cayenne as some time back there were reports of colouring being added to some cayenne batches. If you have some tabasco sauce add a few drops to water and see how you go with that.

I have started taking Cayenne Pepper, I do not know the strength and have a question for some one who knows a bit about it.
I am taking 1/2 a tsp in hot water, straight after taking it my Blood Pressure is going to 150 90 and my pulse over 90. It varies but I am very concerned, I feel dizzy as I write this and and will take my blood pressure again then go and lie down.
Can anyone tell me if this is typical, does it stop some time after getting used to taking it?
My normal BP is 127/75 and pulse between 64 and 72.

The last 4 times I took 1/4 teaspoon of cayenne pepper in a cup of warm water I vomited 3 times and one time I did not vomit. Why? Walter

I have been drinking 1/4 teaspoon of organic cayenne pepper (30K) once a day for the past two days. My stomach is fine and I feel great after drinking it. Although, for the past two nights I have been unable to sleep. My mind doesn't seem to shut down. Everything that I read states that cayenne should augment my sleep. Does anyone know why I am experiencing this side effect?

The other night almost the same thing happen to me. I ate my dinner and then took my cayenne pills (2 of them). Minutes later I started to feel this pain in my stomach. It got worse and worse.... I thought maybe I had to throw up but I really don't like to so I tried not to. I walked into the living room and almost passed out. I laid down on the couch and went into a heavy sweat. Slowly the pain went away and I came back to reality.
Since then I have taken my cayenne pills before I eat. This has not happen again BUT... I can't help but want it to happen again. Even though the pain was really bad at first..... I felt great after the episode was over.
