Did Lydia Pinkham sell menstrual pads?
You might be interested to know that my Beloved Partner (a great-granddaughter of Lydia E. Pinkham) remembers using sanitary napkins made by the Lydia Pinkham Medicine Co. Not sure whether they were for “testing” purposes, or were a complementary product to the Sanative Wash [apparently a douche liquid, advertised in her Home Talks, right-hand page].
