Bittermelon will go on my shopping list more often than it used to go on the shopping list. I use it in stir fry with other veggies. It is eaten in Okinawa which is one of the blue zones where people have the longest lives.
If you are not familiar with bittermelon you can find pictures and information at

I am going to ask my naturopath if I should also take this in supplement form.
