Mooncup - A healthy alternative to tampons The Mooncup is a reusable menstrual cup around two inches long and made from soft silicone rubber. It is worn internally like a tampon but collects menstrual fluid rather than absorbing. Unlike tampons the Mooncup is not a disposable product, so you only need to buy one. The Mooncup will hold 30ml of fluid, which is roughly one third of the average total produced each period. A light seal is formed with your vaginal walls allowing your menstrual fluid to pass into the Mooncup without leakage or odour. You will probably find that you need to empty your Mooncup less frequently than you currently replace towels or tampons. Why is mooncup better for you and the environment? The Mooncup menstrual cup contains no bleaches, deodorisers or absorbency gels. It does not interfere with your healthy vaginal environment. The smooth surface of the Mooncup allows the mucus membranes of your vaginal wall to continue their essential cleansing and protective functions. The Mooncup does not absorb your body`s natural defence mechanisms and will not deposit fibres in your vaginal wall. For your safety the Mooncup is made from a special medical grade non-allergic silicone. Silicone is derived from silica which is one of the most abundant minerals on earth. It will not cause irritation and is suitable for women with sensitive skin, thrush, eczema or an allergy. The Mooncup can be cleaned in the same way as baby equipment: with sterilising fluid, or by boiling for five minutes in an open pan of water. Unlike pads and tampons the Mooncup menstrual cup is reusable, eliminating the need to carry bulky spares. With proper care your Mooncup will last for several years. Imagine the towels and tampons that you will be disposing of in landfill sites during those years! How easy is it to use the Mooncup menstrual cup? Correctly inserted, the Mooncup is so comfortable that you will forget it exists. It may take a little practice at first as you need to find the angle and position that is right for you. Once you have perfected it you will be amazed at how simple the Mooncup is to use. You will need to empty, rinse or wipe and reinsert your Mooncup every four to eight hours depending on your flow. The fluid remains inside the cup, and the process is not messy or uncomfortable. The Mooncup can safely be used overnight and is great for all sports, swimming and travelling.
