I buy the Dr Christopher HOT Cayenne drops and put ONLY 1-2 drops (that is all it takes because each drop is --- per the label ---160,000 Scoville Heat Units Organic Cayenne Pepper AND 200,000 H.U. of Habanero Chili) in a glass of warm filtered water with 1/2 squeezed lemon.
I do this most mornings on an empty stomach for the myriad benefits of the Cayenne.
I get a pure organic Cayenne from amazon in powder form and extract from the powder pure form it takes 45 to 60 days to extract the the pure form with no additives and put it in a eye dropper bottle and add about 20 drops to a glass of infused citrus water and drink it with breakfast and have no side effects basically because alot of the companies mix crap with it as fillers even in their Tinctures as well. The formula was from a Herbologist who recieved her PHd and wrote a study and thesis about all the benifits using it. Would suggest you start out with 10 drops and work up to 20 once a day.
