Herbal Simples Approved for Modern Uses of Cure

by William Thomas Fernie

The word Mushroom may have been derived from the French Moucheron, or Mousseron, because of its growing among moss. The chief chemical constituents of wholesome Mushrooms are albuminoids, carbo-hydrates, fat, mineral matters, and water. When salted they yield what is known as catsup, or ketchup (from the Japanese kitchap). The second most edible fungus of this nature is the Parasol Mushroom (Lepcota procera).

Edible Mushrooms, if kept uncooked, become dangerous: they cannot be sent to table too soon. In Rome our favourite Pratiola is held in very small esteem, and the worst wish an Italian can express against his foe is "that he may die of a Pratiola." If this species were exposed for sale in the Roman markets it would be certainly condemned by the inspector of fungi.

Fairy rings are produced by the spawn, or mycelium, beginning to germinate where dropped by a bird or a beast, and exhausting the soil of carbon, nitrogen, phosphorus and potash, from the centre continuously outwards; whilst immediately within the enlarging ring there is constantly a band of coarse rank grass fed by the manure of the penultimate dead spawn. The innermost starved ground remains poor and barren. In this duplicate way the rings grow larger and larger.

Our edible Mushroom is a Pratella of the subgenus Psalliota, and the Agaricus campestris of English botanists. In common with the esculent Mushrooms of France it contains phosphate of potassium—a cell salt essentially reparative of exhausted nerve tissue and energy.

The old practice of testing Mushrooms with a silver [375] spoon, which is supposed to become tarnished only when the juices are of an injurious quality (i.e., when sulphur is developed therein under decomposition) is not to be trusted. In cases of poisoning by injurious fungi after the most violent symptoms may have been relieved, and the patient rescued from immediate danger, yet great emaciation will often follow from the subsequent effects of the poison: and the skin may exhibit an abundant outbreak of a vesicular eruption, whilst the health will remain perhaps permanently injured. Strong alcoholic drinks should never be taken together with, or immediately after eating Mushrooms, or other innocent fungi. Experienced fungus eaters (mycophagists) have found themselves suffering from severe pains, and some swellings through taking whiskey and water shortly after the meal: whereas precisely the same fungus, minus the whiskey, could be eaten with impunity by these identical experimentalists.

MUSTARD.

The wild Mustard (Brassica Sinapistrum), a Cruciferous herb commonly called Chedlock, from leac, a weed, and kiede, to annoy, grows abundantly as a product of waste places, and in newly disturbed ground.

The Field Mustard (Arvensis) is Charlock, or Brassock; its botanical term, Sinapis, being referable to the Celtic nap, as a general name for plants of the rape kind. Mustard was formerly known as "senvie" in English. It has been long cultivated and improved, especially in Darham.

Now we have for commercial and officinal purposes two varieties of the cultivated plant, the black Mustard (Sinapis nigra), and the white Mustard (Brassica, or Sinapis alba). There is also a plain plant of the hedges, [376] Hedge Mustard (Sisymbrium officinale) which is a mere rustic Simple. It is the black Mustard which yields by its seeds the condiment of our tables, and the pungent yellow flour which we employ for the familiar stimulating poultice, or sinapism. This black Mustard is a tall smooth plant, having entire leaves, and smooth seed pods, being now grown for the market on rich alluvial soil chiefly in Lincolnshire and Yorkshire. In common with its kindred plants it gets its name from mustum, the "must," or newly fermented grape juice, and ardens, burning, because as a condiment, Mustard flour was formerly mixed with home-made wine and sugar. The virtues of black Mustard depend on the acrid volatile oil contained in its seeds. These when unbruised and macerated in boiling water yield only a tasteless mucilage which resides in their skin. But when bruised they develop a very active, pungent, and highly stimulative principle with a powerful penetrating odour which makes the eyes water. From thence is perhaps derived the generic name of the herb Sinapis (Para tou sinesthai tous hopous, "because it irritates the eyes"). This active principle contains sulphur abundantly, as is proved by the discoloration of a silver spoon when left in the mustard-pot, the black sulphuret of silver being formed. The chemical basis of black Mustard is "sinnigrin" and its acid myronic. The acridity of its oil is modified in the seeds by combination with another fixed oil of a bland nature which can be readily separated by pressure, then the cake left after the expression of this fixed oil is far more pungent than the seeds. The bland oil expressed from the hulls of the black seeds after the flour has been sifted away, promotes the growth of the hair, and may be used with benefit externally for [377] rheumatism. Whitehead's noted Essence of Mustard is made with spirits of turpentine and rosemary, with which camphor and the farina of black Mustard seed are mixed. This oil is very little affected by frost or the atmosphere; and it is therefore specially prized by clock makers, and for instruments of precision.

A Mustard poultice from the farina of black Mustard made into a paste with, or without wheaten flour commingled, constitutes one of the most powerful external stimulating applications we can employ. It quickly induces a sharp burning pain, and it excites a destructive outward inflammation which enters much more into the true skin than that which is caused by an old fashioned blister of Spanish fly. This has therefore superseded the latter as more promptly and reliably effective for the speedy relief of all active internal congestions. If the application of Mustard has caused sores, these may be best soothed and healed by lime-water liniment.
