Cayenne pepper will do it.
You get the better quality cayenne at health food stores.
Put it in a pepper type shaker bottle if it isn't already.
And just shake a little into some juice, or water will work.
Hold it in the mouth a little before swallowing.
I've been telling my 78 yr old mother about cayenne and now that we have a relative who is a serious health condition from restricted arteries, she decided to start taking some.
The other day she called me and was almost giddy like a kid since starting to take it.
Cayenne will open up the blood passageways.
I found out about this when my blood pressure was up to 150 and after taking cayenne for a while it was down to 120 where it has stayed for years. I just throw a little in my food.
If someone is in the middle of a heart attack the best thing you can do for them is throw a little in some water and have them put it in their mouth. It will stop the attack.
