You can use these herbal blends to restore cycle balance. They have herbs and berries in them like vitex/chaste tree and red raspberry leaf which help with natural estrogen and progesterone production. You can sip the tea daily "pretending" you are going through a natural cycle over 28-30 days. You can choose to make day one either the 1st day of the full moon or the 1st of the month to keep it easy for you- whatever you prefer.
