IvanD: Hawthorn is often spoken of as heart stabiliser, and has the actions that you have described.

Hawthorn is one of a whole suite of natural occurring substances that can be helpful for the heart.

I have tried hawtorn berries and it does nothing for my high blood pressure. If you really want to lower your blood pressure try Mukta Vati. I heard about it and decided to try it. Gee, THIS STUFF WORKS! It's all natural. I belive you can get it from the internet. If all hope fails try ebay. There are different brands coming out, but I use the "Ivy brand".

I am not sure that all of the answers are contained within this article, but I found it very informational about Hawthorn Berries and their use in light of recent research findings. http://www.herbalencounter.com/2012/03/09/hawthorn-crataegus-spp-may-help-wit...
