It's medicine. But not just any medicine. As you may have inferred from the reused bottles (salad dressing, curry paste, and jam, respectively), this medicine is 100% homemade.
The three bottles above hold three different kinds of extract. Just like vanilla extract (which you can make by this same method, by the way), the method can be simplified down to "add some plant matter to some vodka and wait." Today, what I'm going to talk about is the tall bottle of elderberry extract--how to make elderberry extract, and why you should.
