2 The history and mythology of the nightshade plants
Throughout history, plants from the nightshade family have been both feared and revered. Their uses range from medicinal applications to their role in superstition and sorcery.
Historical use
The historical use of deadly nightshade (Atropa belladonna) is not clearly documented in classical antiquity, but external applications are known from older folk medicine. Its "nonsensical and maddening" effect is often emphasized in medieval herbal books. Hildegard von Bingen, an important figure in medieval medicine and mysticism, associated belladonna with the devil and described its disruptive effect on the human mind.
In folk medicine, deadly nightshade was considered a powerful magic plant. The ethnopharmacologist Christian Rätsch reports of an Eastern European love spell in which the root of the deadly nightshade was dug up and gifts for the plant spirit were left in its place. A potion made from the root was also said to have an aphrodisiac effect, and wearing the root as an amulet was said to attract the affection of other people.
Myths and legends
Belladonna also played a role in witchcraft. Extracts of the plant were used as an ingredient in so-called witches' ointments. Researchers such as Enrico Malizia assume that the women known as witches rubbed these ointments on their bodies to make them believe they could fly or turn into animals. The hallucinogenic effect of these drugs caused such realistic experiences of flight and transformation during sleep that those affected believed in the reality of their dreams. In the witch trials, the hallucinations, erotic dreams and delusional states triggered by the ingredients often led to confessions that confirmed the suspicion of witchcraft.
In Romania, there is a widespread belief that the belladonna in the garden is the seat of the familiar spirit. This belief reflects the plant's deep mythological roots in the culture and shows how plants from the nightshade family play an important role not only in medicine, but also in cultural and spiritual life.
3. Henbane (Hyoscyamus niger)
Description and identification
Black henbane, botanically known as Hyoscyamus niger is a herbaceous plant that belongs to the nightshade family (Solanaceae). This plant is often found on rubble pits or in sunny, well-lit locations. It reaches a height of up to 60 cm and is characterized by its shaggy, sticky, hairy leaves. The flowers of the henbane are dirty yellow and veined purple, with the throat and anthers often also purple in color.
Toxins and their effects
All parts of the henbane plant are highly poisonous, especially the roots and seeds. The plant contains tropane alkaloids such as hyoscyamine and scopolamine, which have a strong central effect on the nervous system. These alkaloids are competitive antagonists of muscarinic acetylcholine receptors, which inhibits signal transmission and can lead to symptoms such as dry mouth, hallucinations, cardiac arrhythmia and, in severe cases, respiratory paralysis. Intoxication with henbane can lead to severe health impairments such as delirium, disorientation and even death.
Medical applications
Historically, henbane was used in medicine and pharmacy, particularly to relieve pain and as an antispasmodic. In modern medicine, however, henbane is hardly used any more due to its strong poisonous effect and the fluctuations in its active ingredient content. Nevertheless, it is interesting to note that the plant used to play a role in folk medicine and even in witchcraft, for example as an ingredient in witches' ointments or as an incense for asthma. In homeopathy, it is used for a variety of conditions such as ADHD, epilepsy and various convulsive conditions, although the direct use of the plant is now considered obsolete.
4. Datura (Datura stramonium)
Description and identification
The common datura, scientifically known as Datura stramonium is a plant from the nightshade family (Solanaceae). This deciduous, poisonous plant is characterized by its great variability in appearance. The leaves are dark green on the upper side, long-stalked, egg-shaped and pointed. They can grow very large, with a diameter of up to 20 cm. The conspicuous trumpet flowers, which stand upright in the forks of the branches, lead to a walnut-sized, densely spiked capsule containing deep brown to black seeds.
Toxins and their effects
The entire datura plant is highly toxic as it contains organic compounds known as tropane alkaloids. These alkaloids, especially hyoscyamine and scopolamine, act as competitive antagonists of the muscarinic acetylcholine receptors, which inhibits signal transmission in the nervous system. Ingestion of even small amounts of these alkaloids can lead to severe symptoms of poisoning in humans and animals, such as sensory illusions, nausea, drowsiness and respiratory paralysis.
Medical applications
In the past, datura was used in medicine to treat asthma and whooping cough, as it served as an antispasmodic and expectorant. Today, however, it is hardly used in modern medicine due to its strong poisonous effect and the fluctuations in its active ingredient content. Nevertheless, it is interesting to note that datura is used in homeopathy for a variety of conditions, although the direct use of the plant is considered obsolete.
5. Belladonna (Atropa belladonna)
Description and identification
The black belladonna, scientifically known as Atropa belladonna is a perennial, herbaceous plant that usually grows between 50 cm and 1.50 m tall. It is characterized by a branched structure and glandular hairs. Its leaves are ovate, whole-margined and stalked, with one large and one small leaf together. A long-stalked flower emerges from between these leaves, the corolla of which is narrowly bell-shaped and varies in color from brown-violet to yellow-green, with purple veins on the inside. The fruit is a spherical, cherry-sized, shiny black berry that is highly poisonous.
Toxins and their effects
Belladonna is known for its highly toxic properties, which are due to the alkaloids it contains, in particular atropine and scopolamine. These alkaloids block the muscarinic receptors of the parasympathetic nervous system, which can lead to symptoms such as dry mouth, dilated pupils, cardiac arrhythmia and, in severe cases, respiratory paralysis. Eating just three to five berries can be fatal for a child, while ten to twenty berries can be a fatal dose for adults.
Medical applications
Historically, extracts of deadly nightshade were used in medicine to treat spasms and colicky pain in the gastrointestinal tract as well as Parkinson's tremor. Today, the plant is hardly used for medicinal purposes due to its strong poisonous effect and the fluctuations in its active ingredient content. Nevertheless, atropine is still used in ophthalmology to dilate pupils, and the plant is used in homeopathic remedies for a variety of complaints, although the direct use of the plant is considered obsolete.
6. conclusion
This fascinating journey through the world of nightshade plants, including deadly nightshade, datura and henbane, reveals the dual face of these plants: their use in traditional and modern medicine and the inherent risks of their poisonous constituents. By looking at their historical use, medicinal applications and mythological significance, it became clear how deeply rooted these plants are in human culture, both as remedies and as symbols of the occult. Their effect on the human nervous system and the possible medicinal applications show that the line between poison and medicine is often thin, underlined by the careful balancing of benefit and danger.
These nightshade plants serve as an impressive example of the power of nature and the need to treat it with respect and careful understanding. The importance of further research and education about these fascinating plants cannot be overstated in order to harness their potential benefits while minimizing the risks. The hope remains that future discoveries in science and medicine will shed new light on the many uses of these ancient plants so that their full power can be harnessed for the benefit of mankind without ignoring their dangers.
