For medicinal plants/trees I grow:
-Aloe

-Italian Oregano
-Purple Basil
-Ashitaba
-Echinacea
-Jujube
-Barbados Cherry
-Red Okra
-Red Stem Malabar Spinach
To name just a few that grow easily here in Phoenix. Just read about the health and nutrient benefits of each. Adding to your diet and never get sick or get hungry. Just the Moringa Tree alone (Nicknamed the Tree of Life) can sustain you. They grow easily. Can grow from a seed to over 20 feet tall in a year and a half, can handle the Phoenix Heat and have no enemies.
