i am blessed to have two hawthorn trees in my yard + they also grow all along the tobacco river, near my home.  when the flowers bloomed, in late may i tinctured fresh flowers and leaves in 100 proof vodka.  it infused for several months.  the berries i collected in late august, and also tinctured fresh in 100 proof vodka.  they infused for months.  i strained them both at the same time, and mixed them together, for a lovely heart tonic.  hawthorn works best when taken on a regualr basis, a half of a dropperful up to a dropperful a day, would be a good place to start.  hawthorn for the aging heart.  comes in a 2 oz dropper bottle.
