The two types of cayenne that I always suggest is African bird and Habenero. This can usually be purchased at most health food stores, but you can also order it from herbal companies. You may take the cayenne as a tea, or you can buy empty gel capsules. You will want to start with a dose a day, and work your way up to at least 3 per day. I have found that by taking the cayenne just before I eat stops the burning in my chest.
Cayenne is so great for many other things as well.
Some people worry about cayenne destroying the lining of their stomach, but it will not do that. As harsh as it is to the tongue, it is very gentle to the body. I can give you much more advice on herbs, but it would help if you could be a little more specific. The herbs will help, but if you are really interested in improving your health as you age, I would suggest you also take a look at your diet. I can help you with that also.
