I know there are many different types of wild lettuce. I have a couple of them in my yard. My question is can you combine them? For example use two different types of leaves in a tea? Most have similar properties and uses so I wonder if they can be used together.
As long as they are safe to consume, they can be cooked together. Many foragers do this. As for making a tea with them, why not just eat them? The young greens on many species can be eaten raw, as in a salad, and the mature leaves in most can be boiled and eaten like collard greens.
