Release - Organic Cleansing Yoni Steaming Herbs For cycles 28 days and longer. Supporting the clearing of stagnation, minimising menstrual cramping and alleviating period pain. Best choice for old residue, postpartum and general use if you have a cycle of 28 days or more. Not suitable for women with short cycles (27 days or less), choose Rejuvenate Gentle Strengthening Herbs instead. Note: If you are not sure which blend to choose, please email us at info@ecoperiod.com.au or send us a web chat message with some details and we will advise prior to your purchase. If you've chosen the wrong herbs, and they are not opened or used, we can exchange, but you will need to pay postage again, so it is worth double checking if you are unsure.
