They have anti diabetes and cancer properties and can also lower your Blood pressure. I didn't harvest them because they were in such good condition, it would seem wrong to cut these beauties. Just thought I would share this awesome find. This one is bigger than my hand. I found the last two About a year ago in the same general area. Don't remember much else.
