I have both. The tincture is usually a synergistic
blend of different kind of capsicum peppers. I use
it sometimes since it is easy to mix with water and
I can carry some in my purse.

I prefer to use the organic ground cayenne and like
it with some lemon and maple syrup. It is important to
have it come in contact with the tongue.

Here is some additional info on dosing~~

People who aren't used to cayenne need to work their way up.
Don't overdo it at first. For those who've never used cayenne
pepper before, a good initial dosage is 1/16th of a teaspoon.
Work your dosage up slowly. Put a small amount in some juice,
stir it in thoroughly and drink.

It's recommended that cayenne powder be used, as opposed to
capsules. Many herbalists believe that you're only getting a
small part of the potential value of cayenne pepper by taking
it in capsule form. When you put cayenne powder in your mouth,
your stomach secretes digestive juices before the cayenne gets
down there. So when the cayenne arrives, your stomach is ready
for it. But if you swallow a capsule, your tongue tastes nothing.
A capsule goes down into your stomach, and your stomach notices
nothing, at first. Then, five minutes later, the gelatin bursts;
you have a half-teaspoon of cayenne pepper in your stomach, and
your body is shocked. You took it by surprise.

What's going on here is that some of cayenne's healing action
occurs right in your mouth. As cayenne touches your tongue, it
starts to be absorbed in seconds, and your nerve endings transmit
signals throughout the body, sending waves of fresh blood wherever
it's needed. Cayenne may be taken at a dosage of 0.5 to 1 gram
three times daily, before meals.

I am in the US but surely you can buy online or at a health
food store there. I get the 90,000 HU and it is great.
Its best to get organic since so much of it is irradiated.
