Chemistry
All species of Mandragora contain highly biologically active alkaloids, tropane alkaloids in particular. Hanuš et al. reviewed the phytochemistry of Mandragora species. More than 80 substances have been identified; their paper gives the detailed chemical structure of 37 of them. Jackson and Berry were unable to find any differences in alkaloid composition between Mandragora officinarum (using the narrowest circumscription of this species) and Mandragora autumnalis (viewed as the main Mediterranean species). Alkaloids present in the fresh plant or the dried root included atropine, hyoscyamine, scopolamine (hyoscine), scopine, cuscohygrine, apoatropine, 3-alpha-tigloyloxytropane, 3-alpha,6-beta-ditigloyloxytropane and belladonnines. Non-alkaloid constituents included sitosterol and beta-methylesculetin (scopoletin).
The alkaloids make the plant, in particular the root and leaves, poisonous, via anticholinergic, hallucinogenic, and hypnotic effects. Anticholinergic properties can lead to asphyxiation. Ingesting mandrake root is likely to have other adverse effects such as vomiting and diarrhea. The alkaloid concentration varies between plant samples, and accidental poisoning is likely to occur. Clinical reports of the effects of consumption of Mandragora officinarum (as Mandragora autumnalis) include severe symptoms similar to those of atropine poisoning, including blurred vision, dilation of the pupils (mydriasis), dryness of the mouth, difficulty in urinating, dizziness, headache, vomiting, blushing and a rapid heart rate (tachycardia). Hyperactivity and hallucinations also occurred in the majority of patients.
Mandrake has a long history of medicinal use, although superstition has played a large part in the uses to which it has been applied. WebMD, which categorises the herb European Mandrake derived from Mandragora officinarum under the heading 'Vitamins & Supplements', declares that it is UNSAFE for anyone to use European mandrake for medicinal purposes. In the UK, The Prescription Only Medicines (Human Use) Order 1997, in its Schedule 1, identifies 'Mandragora autumnalis' as a substance which, if included in medicinal products, makes those products prescription only medicines, and therefore only prescribable by those categories of appropriate practitioners specified in Regulation 214 of The Human Medicines Regulations 2012. Medical herbalists are not recognised as 'appropriate practitioners' under this legislation. Mandragora autumnalis Bertol. is currently an accepted species distinguishable from Mandragora officinarum L., so it follows that mandrake preparations and products derived from Mandragora officinarum L. may not actually be covered by this UK legislation. However, the European Medicines Agency, which oversees the registration of herbal medicinal products in the European Union, does not recognise mandrake, and indeed any Mandragora species, as an approved herbal medicinal product, substance, or preparation under the European Directive on Traditional Herbal Medicinal Products.
The root is hallucinogenic and narcotic. In sufficient quantities, it induces a state of unconsciousness and was used as an anaesthetic for surgery in ancient times. In the past, juice from the finely grated root was applied externally to relieve rheumatic pains. It was also used internally to treat melancholy, convulsions, and mania. When taken internally in large doses, however, it is said to excite delirium and madness.
In the past, mandrake was often made into amulets which were believed to bring good fortune and cure sterility. In one superstition, people who pull up this root will be condemned to hell, and the mandrake root would scream as it was pulled from the ground, killing anyone who heard it. Therefore, in the past, people have tied the roots to the bodies of animals and then used these animals to pull the roots from the soil. In ancient Rome, it was used as a painkiller during surgery.
