For the medicine cabinet; This is Cleaver or Catchweed. It is easy to ID because it cleaves to you. Gathering a small bottle of leaves takes no time at all and once dried the tea can be used to treat kidney and urinary track infections and inflammation. Though it is known mostly because it is a safe and affective treatment for feline lower urinary tract disease (FLUTD), I do not know the amounts for treating cats. People also use it for skin ailments, and a couple other things. It is general blood purifier.
