CHERVIL

Chervil (Anthriscus cerefolium), sometimes called French parsley or garden chervil (to distinguish it from similar plants also called chervil), is a delicate annual herb related to parsley. It was formerly called Myrrhis due to its volatile oil with an aroma similar to the resinous substance myrrh. It is commonly used to season mild-flavoured dishes and is a constituent of the French herb mixture fines herbes.

POISON HEMLOCK

Conium maculatum (hemlock or poison hemlock) is a highly poisonous biennial plant herbaceous flowering plant in the carrot family Apiaceae, native to Europe and North Africa. 

It is a herbaceous biennial plant that grows to 1.5–2.5 m, with a smooth, green, hollow stem, usually spotted or streaked with red or purple on the lower half of the stem. All parts of the plant are hairless (glabrous). The leaves are two- to four-pinnate, finely divided and lacy, overall triangular in shape, up to 50 cm long and 40 cm broad. The flowers are small, white, clustered in umbels up to 10–15 cm across. When crushed, the leaves and root emit a rank, unpleasant odour often compared to that of parsnips. It produces a large number of seeds that allow the plant to form thick stands in modified soils.

The toxicity of the plant has inspired many of its common names: In addition to the English poison hemlock, the Australian Carrot Fern, and the Irish devil's bread or devil's porridge, poison parsley, spotted corobane, and spotted hemlock are used.

Eight piperidinic alkaloids have been identified in C. maculatum. Two of them, gamma-coniceine and coniine, are generally the most abundant, and they account for most of the plant's acute and chronic toxicity. Due to high potency, the ingestion of seemingly small doses can easily result in respiratory collapse and death.

Coniine causes death by blocking the neuromuscular junction in a manner similar to curare; this results in an ascending muscular paralysis with eventual paralysis of the respiratory muscles which results in death due to lack of oxygen to the heart and brain. Death can be prevented by artificial ventilation until the effects have worn off 48–72 hours later. For an adult, the ingestion of more than 100 mg (0.1 gram) of coniine (about six to eight fresh leaves, or a smaller dose of the seeds or root) may be fatal.

In ancient Greece, hemlock was used to poison condemned prisoners. The most famous victim of hemlock poisoning is the philosopher Socrates. After being condemned to death for impiety and corrupting the young men of Athens, in 399 BC, Socrates was given a potent infusion of the hemlock plant. Plato described Socrates' death in 'Phaedo'.

ERYNGIUM

Eryngium is a genus of flowering plants in the family Apiaceae. There are about 250 species. The genus has a cosmopolitan distribution, with the centre of diversity in South America. Common names include eryngo and sea holly (though the genus is not related to the true hollies, Ilex). These are annual and perennial herbs with hairless and usually spiny leaves. The dome-shaped umbels of steely blue or white flowers have whorls of spiny basal bracts. Some species are native to rocky and coastal areas, but the majority are grassland plants.

Species are grown as ornamental plants in gardens. Numerous hybrids have been selected for garden use, of which E. × oliverianum and E. × tripartitum have gained the Royal Horticultural Society's Award of Garden Merit. Many species of Eryngium have been used as food and medicine. Eryngium campestre is used as a folk medicine in Turkey. Eryngium creticum is a herbal remedy for scorpion stings in Jordan. Eryngium elegans is used in Argentina and Eryngium foetidum in Latin America and South-East Asia. Native American peoples used many species for varied purposes. Cultures worldwide have used Eryngium extracts as anti-inflammatory agents.

Eryngium yields an essential oil and contains many kinds of terpenoids, saponins, flavonoids, coumarins, and steroids. The roots have been used as vegetables or sweetmeats. Young shoots and leaves are sometimes used as vegetables like asparagus. E. foetidum is used in parts of the Americas and Asia as a culinary herb. It is not unlike coriander, or cilantro, and is sometimes mistaken for it. It may be called spiny coriander or culantro.

FENNEL FOLIAGE

Fennel (Foeniculum vulgare) is a flowering plant species in the celery family Apiaceae or Umbelliferae. It is the sole species in the genus Foeniculum. It is a hardy, perennial herb with yellow flowers and feathery leaves. It is indigenous to the shores of the Mediterranean but has become widely naturalised in many parts of the world, especially on dry soils near the sea-coast and on riverbanks. It is a highly aromatic and flavourful herb with culinary and medicinal uses and, along with the similar-tasting anise, is one of the primary ingredients of absinthe. Florence fennel or finocchio is a variety with a swollen, bulb-like stem base that is used as a vegetable.
