Great link find, Stone. :)
I have a Passion Flower plant also. I eat the fruits, and it has never done me any harm; and they are actually quite tasty. Of course, it is classed as a narcotic, so be careful! I suggest you do a little research to find out what you can.
Personally, when making Passion Flower tea I like to blend it with Chamomile- the flavors mix very nicely together, especially if you have a certain taste.
Its also advised not to give Passion Flower to pregnant women.
As I said, great link! It provides you with great info including how to grow the plant as you probably saw, and is going into my favorites. Thanks for that Stone :D
