I have looked up what my sticky weed is called and it's a cleaver and also goes by many names - the one I like is 'sticky willy' LOL

As a tea, the plant acts as a diuretic and lymphatic. As a lymphatic tonic, it is used in a wide range of problems involving the lymph system, such as swollen glands (e.g. tonsillitis).

Poultices and washes made from cleavers were traditionally used to treat a variety of skin ailments, light wounds and burns. As a pulp, it has been used to relieve poisonous bites and stings. To make a poultice, the entire plant is used, and applied directly to the affected area.

It's often used for medicine etc - it's amazing what people use it for too....
