Time out of mind, herbs have figured prominently in mystery and romance. Shakespeare is probably the most famous author to incorporate the juice of monkshood as the deadly elixir in Hamlet. Mandrake, the screaming roots in Harry Potter, made up the sleeping potion that sent Juliette into a death-like slumber. Poor Romeo, if only he’d known before he drank belladonna, a member of the deadly nightshade family, or wolf’s bane. It seems no one is quite certain what the ill-fated lover knocked back.

Many whimsical fancies sprang up around the shape of plants. The bell-like flowers of foxglove were thought to be the minute gloves that fairies wore, especially as foxglove bloomed in shady woodlands where everyone knows the little folk dwell. Commonly called digitalis, this now-famous plant is widely used to treat heart disease. But too strong a dose and bang––you have a murder mystery. In Pocketful of Rye, Agatha Christie favored a poisonous concoction made of yew disguised in marmalade. The author hid deadly hemlock in a bottle of cold beer in Five Little Pigs.

Many herbs also had romantic uses. The love potion in Shakespeare’s A Midsummer Night’s Dream has been analyzed by a fellow of the Royal Society of Chemistry in England. Doctor Sell thinks it was made up of heart’s ease (violas) blended with the sweetness of musk roses. In the play, Oberon drops the flowery decoction onto the eyelids of the sleeping Titinia, but the good doctor cautions against trying this at home. Rather, opt for the nape of the neck or the décolleté. Men just love the décolleté––breasts pushed up by a tightly drawn corset for those of you who didn’t realize.

Speaking of romance, it was thought that a young maiden could toss a sprig of St. John’s Wort over her shoulder and soon learn the name of the man she was to marry. Leafy branches of this herb were also hung in windows to ward off evil spirits and burnt to protect against devils, goblins and witches. Bear this in mind, if you’re troubled by them.
Legend has it that angelica was revealed in a dream by an angel to cure the bubonic plague. All parts of the plant were deemed of great value against enchantment. And don’t forget boughs of the sacred rowan tree to ward off evil spells.

Feeling timid? Anoint your feet with catnip tea to embolden yourself. Fennel seed is said to boost desire. Lavender is “of ‘especiall good use for all griefes and paines of the head.” For those of you who would be true, rosemary is the symbol of fidelity between lovers. Traditionally, a wreath of the aromatic herb was worn by brides. Rosemary is also the herb of remembrance left at the grave of loved ones.

Historical writers, especially, can incorporate the use of herbs to flavor their stories, as do I. But anyone can mix in a love potion or fatal elixir to spice up the usual suspects in a suspense or murder mystery.

    Hmmm, good for more than cooking? I do like herbs for fragrances. Good information.

    A nice treasure trove of info here, Beth. I've researched herbalism concerning the use of herbs and spices as embalming agents and wound healing in medieval times. Who says RiteAid has better stuff today? Thanks for another interesting post.

    Hi Beth, in your review of herbs, was there any herb that produced madness? I thought I had heard of such a thing, but now I'm not sure if it's ture or folklore. Do you know?

    The overdose of Mandrake root can cause horrific hallucinations that can last for days and make an individual appear insane.
