In India, we have embraced disposable sanitary pads since a decade or two however we have been using cloth pads since ages now . Our grandmothers and their grandmothers and so on, all were using reusable cloth pads for centuries now, however we in modern times have not embraced the ancient safe practice of reusable cloth pads and shifted to unsafe options without thinking about the health repercussions of the same. If we wash and dry reusable cloth pads properly in open air and sunlight the pads are completely safe to use.
