Cayenne is one herb I would never want to be without. It's good for so many things but we use it a lot to help stop bleeding. Cayenne regulates the blood flow in the body from the head to the feet so that it's equalized. Cayenne is also really really good for your heart.
You probably shouldn't try these remedies on younger kids, unless you think they could handle the burn.
Bloody Nose take some cayenne pepper (the kind you get from the grocery store) and add a few shakes into a small glass of water (like 1/2 cup). Drink it down and the bloody nose should be gone within 10 seconds. I've tried this several times and it works every time without fail. Its a little hot but if you swallow it pretty quick and don't swish it around in your mouth it shouldn't be too bad.
Wounds you can apply cayenne directly on a bleeding wound or take it internally. I sliced my little finger pretty bad the other day, so bad that the blood was seeping out the band aid. I took some cayenne internally (same way as mentioned above) because I just did not like the idea of applying cayenne directly on my wound, ouch! It worked so well, the bleeding stopped within a minute!
Other things Cayenne is good for:
Poor circulation
High or low blood pressure
Hypothermia
Frostbite
Shock
Heart attack
Ulcers
For the life threatening issues, using the tincture (extract) is best because it gets into the blood stream faster.
