Medicinal Herbs for Fictional Use, Part 2

1. Urine, that wonderful liquid gold.

Urine has had many uses in history and in historical medicine, everything from being used as a face wash to tanning hides to a detergent for tough stains. Urea, a main component of urine, is used in many beauty products today that are used to treat dermatological conditions like psoriasis and eczema. Urea can also dissolve the nail plate of an infected or overgrown nail without damaging the healthy tissue.

Now, depending on your fiction world, urine might very well be the most aseptic liquid available. Urea, a component of urine, can debride wounds by breaking down the dead tissue. If it came right down to it in a survival situation, I would probably go with urine over alcohol for a large wound since alcohol kills all tissue, both healthy and non, and the urine of a healthy person probably contains less sugars and odd yeasts than your fermented beverage of choice.

On a side note, urine is supposed to be a wonderful fertilizer so if you have a compost pile of your own...

2. Mullen (Mullein Root, Wild Ice Leaf, Hag's Taper, Candelaria) is still proclaimed today to be a wonderful cure for things like ear infection and respiratory disorders. Historically, the leaves steeped in vinegar were used to treat lameness and internal bruises as well as respiratory congestion. Do note that the hairs on the leaves can cause contact dermatitis, so people shouldn't be picking them without gloves. The flowers are used to create a wash for minor wounds and abrasions.

3. Lobelia inflata (Indian Tobacco) leaves and seeds were used dried, crushed and tightly bottled, made into a tea, tincture or pill. A few teaspoons were given at a time to treat asthma, whooping cough, difficulty breathing, consumption, cholera, lockjaw, rabid animal bites, wasp or poisonous insect stings and, surprisingly, hydrophobia. Lobelia is toxic in large doses and does tend to cause vomiting indicating that the dose needs to be titrated according to response.

4. Knotgrass (Polygonum Aviculare) extract was used for nose and gastric bleeding. When powdered it was drunk with wine to treat poisonous bites. And was in general considered to be a remedy for gangrene, ulcers, broken joints and dysentery.

5. Foxglove (Digitalis Purpurea) was first documented for use in cardiac issues in the late 1700's and contains a strong cardiac glycoside that slows and strengthens the heartbeat. I can't see a reason any character in any of my stories would conceivably use this as it deals more with a chronic condition than an actual disease process. But I found it interesting so I'm including it anyway. Honestly, it would, in fiction land only of course, be more useful as a poison. Overdose of foxglove causes visual disturbances (yellow-green halos around lights), vomiting, dizziness, seizures and ultimately death as it stops the heart.

Well, that's it for this section. This is, of course, in no way comprehensive, but I hope it has helped to imbue a modicum of historical accuracy to your literary endeavors. Happy writings, everyone!
