Be Assertive. The BACH®* remedy Centaury encourages the positive potential to not deny your own needs. You can express and defend your opinions, uninfluenced by others. For when you are finding yourself drained by others, struggling to say no, and feel imposed on. Follow your own path unconstrained by others’ thoughts and feelings. Prevent weak-willed and subservient tendencies; don’t be scared to say “No.”
