Moon phases and earth cycles etc. all have meaning and can be quite powerful effects. With purging type herbs, it makes little differance! This is why i get disgusted at muscle testers, they test an herbs and state it is not needed! The herbs do what they are suppose to do regardless of the muscle test, etc.
You may get better results with the moon cycle, especially if your a woman.
Actually every woman on this earth should have her period with every other non pregnant woman, but disease has them all messed up.
