One Pill and All Your Dreams will Come True. Papaver Rhœas (Common Poppy). Growing wild in our gardens and fields, this is a distant relative of the Opium Poppy. This poppy also contains a bioactive alkaloid, rheadine, a mild sedative used in old herbal medicines. Its other uses back in the early 1800’s include the treatment of coughs and catarrh. Image and text from Woodville’s Medical Botany. Medicine Jack is a song about a “travelling seller of patent medicines (made of rhubarb, squills, butter, soap, flour and cheese), plaisters and tooth extraction”. Believed to be from around 1860s, it shows how buying and selling medicine was very different to nowadays. Images and text from Wellcome Collection.
