We have a hawthorn "tree" (Really, it's a large bush.) out in front of our design studio. Most of its yellow leaves have fallen off in this picture at right (the orange is gro-low sumac), but you can still see
the red berries. These pics were taken after we harvested the cupful below.
Hawthorn berries are said to aid the ciculatory system, reduce high blood pressure, prevent insomnia, and help with a host of other heart-related ailments. Here's agood site for more on health benefits http://www.herbwisdom.com/herb-hawthorn-berry.html. I'll post the whole (simple) process of making a hawthorn extract when I get some pictures.
