Your garden blackberry has more uses than in a cobbler. A tea made from the leaves will stop diarrhea. Eating blackberries has benefits for the eyes, too, because of the antioxidants in the high blue/black color of the berries. During blackberry season, I’ll eat some daily. I noticed after a week of eating the berries, my night vision was much better. I used to see a blinding halo around oncoming cars at night from their headlights. This went away after blackberries and I only saw round lights. Blackberries are very high in iron and are a great blood builder because of this. This can be constipating for some people (and thus can stop diarrhea, too.) Plant some blackberries and you will have a lifetime supply of delicious, nutritious fruit. I’m still picking berries from the plants I started with 25 years ago. Each year, the plant sends up new canes and the old ones are cut away after fruiting. I chose a thorn-less variety and it is delicious. Oh, a tip on picking blackberries. The fruit turns black, then ripens. A ripe blackberry will come off the cane easily and without a cap.
