While "Maiden Blood" sounds like something that would be acquired through improper or even untoward channels. However, this valuable elixir was bottled with much love and care, usually under a full moon.
Throughout history, a very common female occupation has been that of healer. This role arose of necessity. Responsible for their family's health and with little to no access to medications or educated doctors, females learned from very early ages the medicinal properties of all roots, leaves, berries, and herbs that grew within their villages and nearby woods or hills. As time progressed, this knowledge became much more exact, especially as it was passed down among families, notes and recipes were recorded in ledgers, and knowledge was shared among female elders (who were, throughout different periods in history, persecuted as witches).
It has always been widely known (as it is today) that berries and fruits with the deepest, darkest colors are also usually the highest in nutritional or medicinal value. "Maiden Blood" is a generic name for the most colorful (usually red or purple) natural substances gathered in any particular region. Often, these were blackberries, elderberries, ground barks, leaves, and other such harvested items. Practically speaking, Maiden Blood was viewed as a medicinal cure-all. Before being bottled, it was often fermented into an alcoholic spirit, enabling the maker to store large amounts through long winters, and which also gave it the added benefit of dulling pain and being useful as a sleep aid.
While we are not sure of the provenance of this particular Maiden Blood, our sources are fairly sure it originated in Northern Italy during the 1600s. We suggest you try this Maiden Blood at room temperature on the night of a full moon, when it is most potent.
(THIS IS NOT REAL Maiden's Blood, it is a fun holiday decoration and intended for display only! (Contents: food coloring, corn syrup) That being said, witches have always been real and they do still exist today, but they almost exclusively have always been women that look to nature and scientific evidence for solutions, they were women who obtained knowledge that made men and people in positions of power feel threatened, and who were often shunned and persecuted, resulting in exile or death. Happy Halloween!
