Strychnine poisoning can be fatal to humans and other animals and can occur by inhalation, swallowing or absorption through eyes or mouth. It produces some of the most dramatic and painful symptoms of any known toxic reaction, making it quite noticeable and a common choice for assassinations and poison attacks. For this reason, strychnine poisoning is often portrayed in literature and film, such as the murder mysteries written by Agatha Christie. [1]

Contents

The probable lethal oral dose in humans is 1.5 to 2 mg/kg. [2] Similarly, the median lethal dose for dogs, cats, and rats ranges from 0.5 to 2.35 mg/kg. [3]

Presentation in humans

Ten to twenty minutes after exposure, the body's muscles begin to spasm, starting with the head and neck in the form of trismus and risus sardonicus. The spasms then spread to every muscle in the body, with nearly continuous convulsions, and get worse at the slightest stimulus. The convulsions progress, increasing in intensity and frequency until the backbone arches continually. Convulsions lead to lactic acidosis, hyperthermia and rhabdomyolysis. These are followed by postictal depression. Death comes from asphyxiation caused by paralysis of the neural pathways that control breathing, or by exhaustion from the convulsions. The subject usually dies within 2–3 hours after exposure.

One medical student in 1896 described the experience in a letter to the Lancet:

Three years ago I was reading for an examination, and feeling "run down". I took 10 minims of strychnia solution (B.P.) with the same quantity of dilute phosphoric acid well diluted twice a day. On the second day of taking it, towards the evening, I felt a tightness in the "facial muscles " and a peculiar metallic taste in the mouth. There was great uneasiness and restlessness, and I felt a desire to walk about and do something rather than sit still and read. I lay on the bed and the calf muscles began to stiffen and jerk. My toes drew up under my feet, and as I moved or turned my head flashes of light kept darting across my eyes. I then knew something serious was developing, so I crawled off the bed and scrambled to a case in my room and got out (fortunately) the bromide of potassium and the chloral. I had no confidence or courage to weigh them, so I guessed the quantity-about 30 gr. [30 grains, about 2 grams] bromide of potassium and 10 gr. chloral-put them in a tumbler with some water, and drank it off. My whole body was in a cold sweat, with anginous attacks in the precordial region, and a feeling of "going off." I did not call for medical aid, as I thought that the symptoms were declining. I felt better, but my lower limbs were as cold as ice, and the calf muscles kept tense and were jerking. There was no opisthotonos, only a slight stiffness at the back of the neck. Half an hour later, as I could judge, I took the same quantity of bromide, potassium and chloral– and a little time after I lost consciousness and fell into a " profound sleep," awaking in the morning with no unpleasant symptoms, no headache, &c., but a desire " to be on the move " and a slight feeling of stiffness in the jaw.

These worked off during the day. [4]

Treatment

There is no specific antidote for strychnine. "The convulsions are often triggered by stimuli – when your body senses something, neurons want to fire, and if they aren’t controlled seizures occur – so patients are generally kept in quiet, dark rooms." [5] Treatment of strychnine poisoning involves an oral application of an activated charcoal infusion which serves to absorb any poison within the digestive tract that has not yet been absorbed into the blood. Anticonvulsants such as phenobarbital or diazepam are administered to control convulsions, along with muscle relaxants such as dantrolene to combat muscle rigidity. [6] If the patient survives past 24 hours, recovery is probable.

The treatment for strychnine poisoning in the late 19th and early 20th centuries was to administer tannic acid which precipitates the strychnine as an insoluble tannate salt, and then to anaesthetise the patient with chloroform until the effects of the strychnine had worn off.

Detection in biological specimens

Strychnine is easily quantitated in body fluids and tissues using instrumental methods in order to confirm a diagnosis of poisoning in hospitalized victims or to assist in the forensic investigation of a case of fatal overdosage. The concentrations in blood or urine of those with symptoms are often in the 1–30 mg/L range. [7]

Strychnine toxicity in animals

Strychnine poisoning in animals occurs usually from ingestion of baits designed for use against rodents (especially gophers and moles) and coyotes. Rodent baits are commonly available over-the-counter, but coyote baits are illegal in the United States. However, since 1990 in the United States most baits containing strychnine have been replaced with zinc phosphide baits. [8] The most common domestic animal to be affected is the dog, either through accidental ingestion or intentional poisoning. The onset of symptoms is 10 to 120 minutes after ingestion. [9] Symptoms include seizures, a "sawhorse" stance, and opisthotonus (rigid extension of all four limbs). Death is usually secondary to respiratory paralysis. Treatment is by detoxification using activated charcoal, pentobarbital for the symptoms, and artificial respiration for apnea.

In most western nations a special license is needed to use and possess strychnine for agricultural use.

Strychnine is a highly toxic, colorless, bitter, crystalline alkaloid used as a pesticide, particularly for killing small vertebrates such as birds and rodents. Strychnine, when inhaled, swallowed, or absorbed through the eyes or mouth, causes poisoning which results in muscular convulsions and eventually death through asphyxia. While it is no longer used medicinally, it was used historically in small doses to strengthen muscle contractions, such as a heart and bowel stimulant and performance-enhancing drug. The most common source is from the seeds of the Strychnos nux-vomica tree.

An angel of mercy or angel of death is a type of criminal offender who is usually employed as a caregiver and intentionally harms or kills people under their care. The angel of mercy is often in a position of power and may decide the victim would be better off if they no longer suffered from whatever severe illness is plaguing them. This person then uses their knowledge to kill the victim. In some cases, as time goes on, this behavior escalates to encompass the healthy and the easily treated.

Thallium poisoning is poisoning that is due to thallium and its compounds, which are often highly toxic. Contact with skin is dangerous and adequate ventilation should be provided when melting this metal. Many thallium compounds are highly soluble in water and are readily absorbed through the skin. Exposure to them should not exceed 0.1 mg per m2 of skin in an 8 hour time-weighted average.

Christiana Edmunds, was an English murderer, popularly known as the "Chocolate Cream Killer", who carried out a series of poisonings in Brighton during the early 1870s. Edmunds purchased confectionery from a local shop and laced them with strychnine before returning them to be sold to unsuspecting members of the public. Her actions resulted in several people becoming seriously ill, and at least one death. Arrested and put on trial, Edmunds was initially sentenced to death. However, this was later commuted to life imprisonment. She spent the rest of her life at the Broadmoor Criminal Lunatic Asylum, dying there in 1907.

<span class="mw-page-title-main">Gelsemine</span> Chemical compound

Gelsemine (C20H22N2O2) is an indole alkaloid isolated from flowering plants of the genus Gelsemium, a plant native to the subtropical and tropical Americas, and southeast Asia, and is a highly toxic compound that acts as a paralytic, exposure to which can result in death. It has generally potent activity as an agonist of the mammalian glycine receptor, the activation of which leads to an inhibitory postsynaptic potential in neurons following chloride ion influx, and systemically, to muscle relaxation of varying intensity and deleterious effect. Despite its danger and toxicity, recent pharmacological research has suggested that the biological activities of this compound may offer opportunities for developing treatments related to xenobiotic or diet-induced oxidative stress, and of anxiety and other conditions, with ongoing research including attempts to identify safer derivatives and analogs to make use of gelsemine's beneficial effects.
