Abstract

Datura stramonium is a well-known cosmopolitan weed known by several common names: thorn apple (due to the appearance of its fruits), Angelʼs trumpet (linked to its flowers), loco seed (referring to the hallucinogenic properties of its seeds), jimson weed (originating from the first recorded poisoning involving this plant), and apple of Peru (indicating the plantʼs origin). All parts of the plant contain the tropane alkaloids hyoscyamine, scopolamine, and atropine together with several minor alkaloids, which cause poisoning such as typical anticholinergic syndrome with neuropsychiatric effects. A review of 114 papers from various databases (Scopus, Web of Science, PubMed, and Google Scholar) revealed that poisoning incidents involving this plant have been relatively common from 2001 to 2024. The analysis indicated that all cases of poisoning from D. stramonium can be categorized into two main groups: accidental and misuse. Accidental poisonings are primarily linked to the contamination of other crops in the field, leading to mass poisoning of humans and animals. They can also result from misidentifying the plant as another edible species, childrenʼs curiosity, and self-medication. On the other hand, misuse is typically associated with recreational drug use, suicide attempts, criminal activities, and magico-religious practices. To prevent poisoning from this plant, it is essential to eliminate the weed from fields, yards, gardens, and other disturbed areas. Additionally, it is important to educate the general public about the plantʼs appearance and the dangers associated with its consumption, particularly in the context of self-medication and recreational drug use.


Introduction

Datura stramonium L. is a well-known cosmopolitan weed that grows in temperate regions, along roadways, pastures, and other marginal areas, but also on arable land together with many crops [1], [2]. It is annual plant, from the Solanaceae family, with a light beige tap root system (12 – 30 cm in length and 0.5 – 2 cm in diameter) and numerous side roots [3]. The plant is smelly (sometimes called stinkweed), 75 – 90 cm tall, with an erect, stout branching stem [1]. Leaves are alternating, unevenly or sharply toothed, and glabrous [4]. The leaves have a bitter, nauseating taste [5]. The flowers are white, five-lobed, trumpet-shaped, and the fruit is a spinous capsule with tiny, flattened, blackish-brown seeds (in some regions called loco seed) ([Fig. 1]) [5].

It is commonly known as thorn apple or Angelʼs trumpet, which is associated with the appearance of the fruits and flowers of this plant [6], [7]. Another, very common name for this plant is jimson weed, actually a shortened version of Jamestown weed, introduced after the first recorded accidental ingestion that happened in Jamestown, Virginia (USA) in 1676 [8], [9]. Succinctly, English soldiers sent to Jamestown to quell Baconʼs Rebellion, ate copious amounts of D. stramonium young leaves as a boiled salad and expressed bizarre and foolish behavior during an 11-day period [10]. Additionally, apple of Peru is sometimes used as a name for D. stramonium, referring to the origin of this plant, and its ancient use in surgical operations by Peruvian healers as an anesthetic (600 – 800 AD) [1].

The name of genus Datura is taken from dhattūra, an ancient Arabic word meaning “divine inebriation”, while the name of the species stramonium originates from the Greek language, as a combination of the words: strychnos – deadly and manikos – mad [11], [12], [13].

The whole plant contains the tropane alkaloids L-hyoscyamine and scopolamine, as well as atropine, which is a racemic mixture of L-hyoscyamine and D-hyoscyamine [14]. Practically, L-hyoscyamine is the dominant tropane alkaloid, as a precursor for the synthesis of scopolamine, and an enantiomer of atropine that is formed by racemization during the extraction [15]. Additionally, several minor tropane alkaloids have also been found [16].

Although several alkaloids are present in D. stramonium, atropine is the most widely used in pharmacological formulations because it is stable and does not racemize in solution [17], [18]. In general, tropane alkaloids are reliable antagonists of muscarinic receptors, used in eye therapy, preoperative administration in surgery, and the treatment of organophosphorus and carbamate poisoning [18], [19], [20], [21], [22], [23]. However, overdose with tropane alkaloids can lead to increased antimuscarinic side effects, which are typical of D. stramonium poisoning.

The clinical signs of poisoning with D. stramonium begin within 30 – 60 min after ingestion, as a typical anticholinergic syndrome with neuropsychiatric effects [16], [24]. “Hot as a hare, blind as a bat, dry as a bone, red as a beet, and mad as a hen” is the proverbial saying which, in the best way, describes symptoms of poisoning with tropane alkaloids [24], [25], [26], [27], [28].

The primary toxic manifestations include mydriasis (due to blockades of the papillary sphincter muscle and iris muscle), dry mouth (due to a salivary secretion blockade), tachycardia (due to competition at the muscarinic receptors in the postganglionic parasympathetic neurons and a blockade of receptors in the sinoatrial node), and fever and erythema (due to vasodilatation and inhibition of sweating) [29]. The neuropsychiatric effects occur due to the depressant activity of Datura alkaloids on the central nervous system including speech disorders, agitation, aggression, and hallucinations [16], [30]. Rarely, hyperthermia, respiratory arrest, and convulsions may be observed. It may result in coma if taken at a very high dose [8].

However, sometimes symptoms can be misidentified with some other diagnosis such as stroke [31], encephalitis [32], food poisoning [33], or even “bath salt” intoxication [34]. Therefore, appropriate recognition and management of D. stramonium poisoning is very important especially in pediatrics [35].

The treatment of D. stramonium intoxication includes gastrointestinal decontamination (emesis, gastric lavage, and activated charcoal), hydration via intravenous fluids, sedation (diazepam), oxygen supplementation, and physostigmine as an antidote in severe cases where the patient has resistant delirium or agitation [36], [37]. In all cases, symptoms regressed after approximately 24 h, leading to a full recovery after 48 h [37].

Nevertheless, D. stramonium possesses medicinal purposes as well. In traditional medicine worldwide, it is mainly used to treat respiratory ailments (asthma and bronchitis), skin conditions (ulcers, wounds, inflammation, bruises, hemorrhoids) and musculoskeletal disorders (rheumatism and gout, sciatica) [38], [39], [40], [41]. However, sometimes a wider range of usages is stated in ethnomedicine (headache, toothache, menstrual blood, sexual stimulant, sedative, swellings, fever, etc.) and ethnoveterinary practices (nerve problems, yoke sore, wounds, dermatophytosis, mastitis, trypanosomiasis, blackleg, anthrax, nasal bleeding, and diarrhea) [42], [43], [44], [45]. On the other side of the spectrum, modern pharmacological studies proved that D. stramonium possesses antioxidant, antimicrobial, anti-inflammatory, and antitumor activities [46].

The aim of this study was to conduct a thorough search of scientific databases (Scopus, Web of Science, PubMed, and Google Scholar) to comprehensively review all documented cases of D. stramonium poisoning in the 21st century. Additionally, an analysis was performed to systematically assess the findings of the selected 114 articles and draw conclusions regarding the causes of poisoning.


Material and Methods

Search strategy

The literature was searched (in November 2024) within article titles, abstracts, and key words using “Datura stramonium poisoning” through three databases (Scopus, Web of Science, and PubMed) to identify relevant case studies published during the 21st century (period between 2001 and 2024). To obtain a complete overview, the relevant publications available from the Google Scholar database were also taken in account. Descriptive statistics were applied throughout the manuscript to summarize and characterize the data.


Selecting studies

A total of 360 studies were retrieved from the following databases: Scopus (146 results), Web of Science (90 results), Pub Med (124 results). After removing duplicates, 216 studies remained. Subsequently, after screening the titles and abstracts, 131 studies were excluded (review articles, out of scope, unavailable documents, referring to the same case, referring period before range of observation). The remaining 85 studies were further reviewed, together with additional relevant studies from the Google Scholar database (29). A total 114 studies were finally included in the analysis.



Results of the Study

The review of the 114 articles ([Table 1]) showed that poisoning with D. stramonium could be divided into two groups: accidental and misused ([Fig. 2]). Moreover, some articles referred to different causes of poisoning [47], [48]. Therefore, it is duplicated in different groups. However, several articles have not specified the exact cause of poisoning with this plant (N/A), while case studies were presented in five articles.

Accidental poisoning

Contamination in the field – humans

D. stramonium is a common weed through temperate and subtropical regions in many summer crops including cereals, legumes, and leafy vegetables [149], [150]. It is an annual weed that produces a large quantity of seeds (up to 30 000 seeds per plant), stays dormant, and supports prolonged survival in the field for years after the first infestation [150], [151].

There are several cases of large outbreak human poisoning with D. stramonium due to contamination of crops such as buckwheat [94], [95], broomcorn [57], [144], millet [33], corn [64], [65], [137], soybean [64], [65], spinach [49], [55], [56], amaranth [32], and purslane [92]. A total of 11 (actually 13; two papers referred to the same case so we excluded them, but the references are given in the footnote) papers have been published on contamination in the field, with 8 referring to mass poisoning and 3 focusing on individual or family cases. In summary, more than 674 people were poisoned, and 5 fatalities occurred.


Contamination in the field – animals

Similar to human poisoning by D. stramonium entering the food chain, animals are also affected in the same way. Animals in pastures typically avoid consuming this plant, which can be attributed to their natural feeding behavior, anti-nutritive properties, and the repulsive smell of D. stramonium [72], [152]. For this reason, less than 1% of poisonings have been reported in grazing animals [152]. However, poisonings have been reported in housed horses and cattle due to corn silage and hay contaminated with D. stramonium [72], [118], [125], [129], [133]. Additionally, a case of poisoning in a pet poodle was reported after it ingested D. stramonium seeds [146]. A total of 6 studies reported animal poisoning, including 2 studies on cattle (involving 30 bulls and 2 dairy cows), 3 studies on horses (involving 56 horses, 3 of which died), and 1 study on a pet.



Mistaken identity

A review of the literature identified 14 studies where D. stramonium was mistakenly identified as another plant. It is often recognized as a leafy vegetable that is used to make a range of dishes, such as soups, stews, omelets, and rice [31], [53], [62], [71], [86], [102], [128], as well as for brewing herbal tea [61], [75]. Furthermore, there are instances of D. stramonium seeds being applied instead of poppy seeds [70] as well as black cumin seeds [73]. Additionally, D. stramonium root has been mistaken for burdock root [100], and its flowers have been misidentified with pumpkin flowers [127]. The literature reviewed indicates that incorrect identification of the plant frequently leads to poisoning among family members.


Childrenʼs curiosity

Large trumpet-shape flowers and spinous seed capsules are very attractive to children [153]. However, children are particularly susceptible to atropine toxicity, even with small amounts producing marked central nervous system features [93]. A total of 17 papers reported the poisoning of 31 children by D. stramonium. Typically, the cases involve children aged 1 to 10 years, with one instance of ocular poisoning recorded in a 12-year-old boy (average age 5.5 ± 2.39; median age 5).


Self-medication

D. stramonium poisonings are a rare occurrence in the 21st century in comparison to previous periods, especially the 18th and 19th centuries [154]. Today this plant is considered unsafe for self-medication due to its toxicity [99]. However, 16 papers have documented cases of D. stramonium poisoning resulting from self-medication. D. stramonium has been used to treat various conditions, including asthma [58], [107], [115], hemorrhoids [77], [78], [101], [103], [138], diarrhea [59], constipation [66], burning sensation during urination [8], abdominal pain [105], stomach cramps and irritation [114], and to alleviate gallstone pain [126].

According to many cultures, the most popular usage of this plant is in asthma treatment by smoking [155]. Up until 1992, D. stramonium was widely used for treating asthma, by smoking a pipe, medicinal cigarettes, and for nonsmokers and children, by inhaling powder smoke or by nebulization [156]. For these purposes, D. stramonium is commonly combined with potassium nitrite, tobacco, tea leaves, chestnut leaves, and gum benzoin [157]. However, the use of anti-asthmatic cigarettes was discontinued due to their short-term effects (much shorter than those of modern drug therapies) and the risk of addiction from excessive use [158]. Additionally, D. stramonium cigarettes mask the progression of lung damage [58].

D. stramonium has strong analgesic properties and is commonly used in ointments to treat skin conditions such as acne, eczema, burns, fistulas, abscesses, and wounds, as well as hemorrhoids, severe neuralgia, and rheumatism [159], [160], [161]. However, no poisonings have been reported with external application. The issue occurs when D. stramonium is ingested to treat these conditions.


Misuse

Magico-religious

In Indian mythological belief (Hinduism), in the performance of the occasion of Shivratri (a festival celebrating Lord Shiva, also known as the Master of poison and medicine), worshippers offered D. stramonium, among other toxic plants, to offer tribute [38], [162]. In practice, the plant is frequently misused during religious ceremonies [163]. It is common to consume fermented drinks made with D. stramonium leaves, Cannabis sativa, Eleusine coracana seeds, and honey, as well as other ritual foods prepared with D. stramonium [164]. A total of two papers refer to D. stramonium poisoning during this festival [60], [63].


Predatory

D. stramonium is occasionally mixed with food and given to unsuspecting individuals or travelers to aid in robberies or sexual assaults, earning it the nickname “roadside poison” [165], [166]. A total of four papers document this form of D. stramonium misuse. It includes mixing D. stramonium seeds with juice or other drinks [52], [82] and incorporating them into sweets made from groundnut seeds and sugar crystals (known as prasad) [88], as well as cookies [167]. Additionally, inhaling D. stramonium powder from a piece of cloth is also reported [68].


Suicide

Intentional poisoning with D. stramonium has been documented in three attempted suicide cases [48], [85], [91], all of which involved individuals with prior suicide attempts. One case featured a 58-year-old female patient with depression who ingested D. stramonium seeds [85]. Similarly, a 38-year-old man consumed D. stramonium seeds [91], and a 54-year-old man ingested ten raw D. stramonium leaves [48]. Fortunately, none of the cases mentioned were fatal.


Recreational drug use

The psychedelic effects of D. stramonium have been recognized for centuries across various cultures and regions [24]. This plant is commonly used as an alternative drug due to its hallucinogenic and euphoric effects, particularly among adolescents and young adults [81], [104], [168]. Additionally, it is an easily available weed and is not classified as an illegal substance [130]. Furthermore, the widespread availability of information on the Internet and communication among youth has led to an increase in the use of D. stramonium for recreational purposes, often in combination with alcohol and other substances such as cannabis [16], [132], [169].

In the 21st century, 36 case reports documented poisoning incidents resulting from the recreational use of D. stramonium. These studies reported a total of 65 patients who exhibited typical anticholinergic syndrome and neuropsychiatric effects due to D. stramonium poisoning. Unfortunately, two of the cases were fatal, involving two 19-year-old males from Greece and Israel, repsectively [28], [136]. Generally, the cases of recreational use of D. Stramonium involve patients ranging from 12 to 33 years old, with an average age of 19.3 ± 5.55 years and a median age of 17. It is crucial to highlight that D. stramonium can cause toxicity in multiple organs, including the liver, heart, kidneys, and brain. Moreover, due to the prolonged abuse of D. stramonium seeds, in addition to aggressive and assaultive behavior and hallucinations, paranoid schizophrenia could develop [87]. As a result, the recreational use of this plant among young people should be strongly discouraged [170].



N/A Cases

In three cases, the exact cause of D. stramonium poisoning was not specified. For example, the case involves a previously healthy 23-year-old male who experienced restlessness, an altered mental state, and hallucinations 2 h after consuming herbal tea [50]. The focus of the case report was on using artificial intelligence software to determine the identity of the plant. Furthermore, Parissis et al. [141] focused on the neurological findings in a case of a coma in a previously healthy 20-year-old male who became unresponsive following the ingestion of D. stramonium seeds. Additionally, the fatal poisoning of an adult Caucasian male due to D. stramonium, with death attributed to a heart attack, highlights the forensic method of identifying atropine and scopolamine through HPLC analysis [2].



Case Studies

Although Forrester [36] reports instances of D. stramonium poisoning from 1998 to 2004, we decided to present it. According to the report, there were 188 recorded cases of D. stramonium poisoning in Texas, USA. The author highlights that the highest number of poisonings occur between June and October, with most cases involving men (82%) and teenagers (72%) who often misuse the plant as a recreational drug (78%). Additionally, Enfield et al. [76] reported 14 cases of poisoning involving Datura species in a regional poison control center in Arizona, USA, covering an 8-year period from 2003 to 2010.

Niewinska et al. [122] documented 28 cases of D. stramonium poisoning in children in Poland. The group was made up of 75.7% males and 14.3% females, with an average age of 14.5 years (ranging from 13 to 17 years). Moreover, in Iran, between 2008 and 2011, 19 cases of D. stramonium poisoning were reported, with most of the incidents involving children who accidentally ingested the plant [98]. Teenagers were the next most common group, using it intentionally for its hallucinogenic effects, while poisoning in adults was rare. The average age of the patients in this study was 12.2 years (ranging from 3 to 29 years), with males making up 67% of the cases.

Between 2005 and 2017, a total of 102 cases of Datura sp. poisoning were reported in Hungary, with the majority occurring from August to October, when the plantʼs fruits and seeds ripened [69]. The authors observed that D. stramonium was consumed both alone and in combination with alcohol, other plants, or psychoactive substances. Males were affected three times more frequently than females. While accidental ingestion was less frequent, it was recorded in young children, as well as in instances of improper use of traditional herbal remedies or suicide. However, most cases involved individuals misusing the plant for hallucinogenic properties.


Conclusion

D. stramonium has been an important mystical plant since ancient times. In contemporary times, poisoning from this plant is mainly attributed to its widespread presence as well as its coexistence and similar appearance to edible plants. Consumption of food and feed contaminated with tropane alkaloids from D. stramonium has resulted in poisoning in both humans and animals. Children are especially at risk, often poisoned after being attracted to the plantʼs capsules and seeds. Furthermore, drug users are familiar with the plant, using it recreationally for its hallucinogenic properties.
