I have the website and all the information!
Lydia Pinkham is an "herbal remedy" that is supposed to enhance fertility. There is some speculation that it could increase your chances of conceiving a girl, if you are hoping for a daughter.
Although you've likely never heard of her, in the 1880s Lydia Pinkham was a household name. Lydia began selling her home-brewed herbal remedy to make ends meet after her wealthy husband went bankrupt, and developed a patent medicine empire. In an age when women were second-class citizens, Lydia Pinkham not only succeeded in a man's world, she became a business magnate. In the field of marketing, she is considered a pioneer and an innovater in marketing to women.
Lydia Pinkham's Tonic Lydia Pinkham's Vegetable Tonic was a popular remedy for "female complaints" and the elixer was promised to cure every womanly ailment from menstrual discomfort to infertility to the dreaded prolapses uteri. Advertisements claimed there was "a baby in every bottle," and women of the time, uncomfortable discussing feminine problems with male doctors, turned to Lydia. Many were scandalized when, as required by the new Pure Food and Drug act, it was revealed that the tonic was 20% alcohol. The glass tonic bottles, advertisements, and pamphlets are now interesting collectibles.
Today, Lydia Pinkham's herbal compound is again available, although the extravagant promises have been reduced the the modest claim that it will "make you feel better" during menstruation and menopause because it offers "nutritional support". (Whether it is still made using the 40-proof recipe Mr. Pinkham won in a card game, I don't know.)
I wrote several pages about Lydia Pinkham, see the link below (includes link to buy LP as well).
