---History---The tree has always been a favourite, and in Shakespeare's time, as Gerard tells us, Almond trees were 'in our London gardens and orchards in great plenty.' There are many references to it in our early poetry. Spenser alludes to it in the Fairy Queen:

'Like to an Almond tree ymounted hye,

On top of greene Selinis all alone,

With blossoms brave bedecked daintly;

Whose tender locks do tremble every one

At everie little breath that under Heaven is blowne.'

The early English name seems to have been Almande: it thus appears in the Romaunt of the Rose. Both this old name and its more modern form came through the French amande, derived from the late Latin amandela, in turn a form of the Greek amygdalus, the meaning of which is obscure.

The tree grows freely in Syria and Palestine: it is mentioned in Scripture as one of the best fruit trees of the land of Canaan, and there are many other biblical references to it. The Hebrew name, shakad, is very expressive: it signifies 'hasty awakening,' or 'to watch for,' hence 'to make haste,' a fitting name for a tree, whose beautiful flowers appearing in Palestine in January, herald the wakening up of Creation. The rod of Aaron was an Almond twig, and the fruit of the Almond was one of the subjects selected for the decoration of the golden candlestick employed in the tabernacle. The Jews still carry rods of Almond blossom to the synagogues on great festivals.

As Almonds were reckoned among 'the best fruits of the land' in the time of Jacob we may infer they were not then cultivated in Egypt. Pliny, however, mentions the Almond among Egyptian fruit-trees; and it is not improbable that it was introduced between the days of Jacob and the period of the Exodus.

Almonds, as well as the oil pressed from them, were well known in Greece and Italy long before the Christian era. A beautiful fable in Greek mythology is associated with the tree. Servius relates that Phyllis was changed by the gods into an Almond tree as an eternal compensation for her desertion by her lover Demophoon, which caused her death by grief. When too late, Demophoon returned, and when the leafless, flowerless and forlorn tree was shown him, as the memorial of Phyllis, he clasped it in his arms, whereupon it burst forth into bloom - an emblem of true love inextinguishable by death.

During the Middle Ages, Almonds became an important article of commerce in Central Europe. Their consumption in medieval cookery was enormous. An inventory, made in 1372, of the effects of Jeanne d'Evreux, Queen of France, enumerates only 20 lb. of sugar, but 500 lb. of Almonds.

The ancients attributed many wonderful virtues to the Almond, but it was chiefly valued for its supposed virtue in preventing intoxication. Plutarch mentions a great drinker of wine, who by the use of Bitter Almonds escaped being intoxicated, and Gerard says: 'Five or six, being taken fasting, do keepe a man from being drunke.' This theory was probably the origin of the custom of eating salted Almonds through a dinner.

---Description---The Almond belongs to the same group of plants as the rose, plum, cherry and peach, being a member of the tribe Prunae of the natural order Rosaceae. The genus Amygdalus to which it is assigned is very closely allied to Prunus (Plum) in which it has sometimes been merged; the distinction lies in the fruit, the succulent pulp attached to the stone in the plum (known botanically as the mesocarp) being replaced by a leathery separable coat in the almond which is hard and juiceless, of a dingy green tinged with dull red, so that when growing it looks not unlike an unripe apricot. When fully ripe, this green covering dries and splits, and the Almond, enclosed in its rough shell (termed the endocarp) drops out. The shell of the Almond is a yellowish buff colour and flattened-ovoid in shape, the outer surface being usually pitted with small holes; frequently it has a more or less fibrous nature. Sometimes it is thin and friable (soft-shelled Almond), sometimes extremely hard and woody (hard-shelled Almond). The seed itself is rounded at one end and pointed at the other, and covered with a thin brown, scurfy coat. The different sorts of Almonds vary in form and size, as well as in the firmness of the shell. The fruit is produced chiefly on the young wood of the previous year, and in part on small spurs of two and three years growth.

The tree is of moderate size, usually from 20 to 30 feet high, with spreading branches the leaves lance-shaped, finely toothed (or serrated) at the edges. The flowers are produced before the leaves - in this country early in March; and in great profusion. There are two principal forms of the Almond the one with entirely pink flowers, Amygdalus communis, var. dulcis, producing Sweet Almonds; the other, A. communis, var. amara, with flowers slightly larger, and the petals almost white towards the tips, deepening into rose at the base, producing Bitter Almonds. Botanically, they are considered merely variations of the one type, and the difference in variety has been supposed originally to be mainly owing to climate, the Bitter Almond being a native of Barbary. The Sweet Almond is the earliest to flower, and is cultivated more largely than the Bitter Almond. It is valuable as a food and for confectionery purposes, as well as in medicine, being rich in a bland oil, and sustaining as a nutriment: the staying power conferred by a meal of Almonds and raisins is well known. It is only the Bitter Almond in the use of which caution is necessary, especially with regard to children, as it possesses dangerous poisonous properties.

---Cultivation---The early, delicate flowers of the Almond give it a unique position among ornamental trees, and it should have a place in every shrubbery, for it will flourish in any ordinary, well-drained soil, both in open and somewhat sheltered situations, and does well in town gardens.

There are several varieties, differing in colour and size of the flowers: one dwarf variety, A. nana, a native of the Lower Danube, is especially decorative, and is often planted in the forefront of shrubberies. All the species are deciduous.

Sicily and Southern Italy are the chief Almond-producing countries; Spain, Portugal, the South of France, the Balearic Islands and Morocco also export considerable quantities.

In the southern counties of England it is not uncommon for the tree to produce a fair crop of fruit, though it is mostly very inferior to that which is imported, but in less favoured districts in this country the production of fruit is rare.

The tree is liable to destruction by frosts in many parts of Central Europe. In France and Belgium, when grown in gardens for its fruit, the tender-shelled varieties are preferred, and the cultivation is the same as for the peach.

---SWEET ALMOND---

Family: N.O. Rosaceae
Botanical: Amygdalus communis (LINN.) var. dulcis

• Medicinal Action and Uses
• Constituents

The annual import of Sweet Almonds into this country is normally over 500 tons.

Sweet Almonds have a bland taste, and the white emulsion formed when they are bruised with water is characterized by no marked odour, the seeds being thus distinguished from Bitter Almonds.

---Medicinal Action and Uses---Fresh Sweet Almonds possess demulcent and nutrient properties, but as the outer brown skin sometimes causes irritation of the alimentary canal, they are blanched by removal of this skin when used for food. Though pleasant to the taste, their nutritive value is diminished unless well masticated, as they are difficult of digestion, and may in some cases induce nettlerash and feverishness. They have a special dietetic value, for besides containing about 20 per cent of proteids, they contain practically no starch, and are therefore often made into flour for cakes and biscuits for patients suffering from diabetes.

Sweet Almonds are used medicinally, the official preparations of the British Pharmacopoeia being Mistura Amygdalae, Pulvis Amygdalae Compositus and Almond Oil.

On expression they yield nearly half their weight in a bland fixed oil, which is employed medicinally for allaying acrid juices, softening and relaxing solids, and in bronchial diseases, in tickling coughs, hoarseness, costiveness, nephritic pains, etc.

When Almonds are pounded in water, the oil unites with the fluid, forming a milky juice - Almond Milk - a cooling, pleasant drink, which is prescribed as a diluent in acute diseases, and as a substitute for animal milk: an ounce of Almonds is sufficient for a quart of water, to which gum arabic is in most cases a useful addition. The pure oil mixed with a thick mucilage of gum arabic, forms a more permanent emulsion; one part of gum with an equal quantity of water being enough for four parts of oil. Almond emulsions possess in a certain degree the emollient qualities of the oil, and have this advantage over the pure oil, that they may be given in acute or inflammatory disorders without danger of the ill effects which the oil might sometimes produce by turning rancid. Sweet Almonds alone are employed in making emulsions, as the Bitter Almond imparts its peculiar taste when treated in this way.

Blanched and beaten into an emulsion with barley-water, Sweet Almonds are of great use in the stone, gravel, strangury and other disorders of the kidneys, bladder and biliary ducts.

By their oily character, Sweet Almonds sometimes give immediate relief in heartburn. For this, it is recommended to peel and eat six or eight Almonds.

Almonds are also useful in medicine for uniting substances with water. Castor oil is rendered palatable when rubbed up with pounded Almonds and some aromatic distilled water.

The fixed Oil of Almonds is extracted from both Bitter and Sweet Almonds. If intended for external use, it must, however, be prepared only from Sweet Almonds.

The seeds are ground in a mill after removing the reddish-brown powder adhering to them and then subjected to hydraulic pressure, the expressed oil being afterwards filtered and bleached, preferably by exposure to light.

---Constituents---Almond oil is a clear, pale yellow, odourless liquid, with a bland, nutty taste. It consists chiefly of Olein, with a small proportion of the Glyceride of Linolic Acid and other Glycerides, but contains no Stearin. It is thus very similar in composition to Olive Oil (for which it may be used as a pleasant substitute), but it is devoid of Chlorophyll, and usually contains a somewhat larger proportion of Olein than Olive Oil.

It is used in trade, as well as medicinally, being most valuable as a lubricant for the delicate works of watches, and is much employed as an ingredient in toilet soap, for its softening action on the skin. It forms a good remedy for chapped hands.

Gerard says:

'The oil newly pressed out of Sweet Almonds is a mitigator of pain and all manner of aches, therefore it is good in pleurisy and colic. The oil of Almonds makes smooth the hands and face of delicate persons, and cleanseth the skin from all spots and pimples.'

And Culpepper writes:

'The oil of both (Bitter and Sweet) cleanses the skin, it easeth pains of the chest, the temples being annointed therewith, and the oil with honey, powder of liquorice, oil of roses and white wax, makes a good ointment for dimness of sight.'

Culpepper also tells us of Almond butter, saying:

'This kind of butter is made of Almonds with sugar and rose-water, which being eaten with violets is very wholesome and commodious for students, for it rejoiceth the heart and comforteth the brain, and qualifieth the heat of the liver.'

BITTER ALMOND

Family: N.O. Rosaceae
Botanical: Amygdalus communis (LINN.) var. amara

• Constituents
• Adulterations and Substitutes

The seeds are used chiefly as a source of Almond Oil, but also yield a volatile oil, which is largely employed as a flavouring agent.

Bitter Almonds are usually shorter, proportionately broader and smaller, and less regular than the Sweet Almonds. They contain about 50 per cent of the same fixed oil which occurs in the Sweet Almond, and are also free from starch. The bitter taste is characteristic.

[Top] [Top of BITTER ALMOND]

---Constituents---The Bitter Almond differs from the Sweet Almond in containing a colourless, crystalline glucoside, Amygdalin, of which the Sweet are entirely destitute. This substance is left in the cake obtained after the oil has been expressed, and can be extracted from it by digestion with alcohol. Many other Rosaceous plants contain Amygdalin, such as the peach, apricot, plum, etc., not only in the seed, but also in the young shoots and flower-buds.

The Bitter Almond seed also contains a ferment Emulsin, which in presence of water acts on the soluble glucoside Amygdalin yielding glucose, prussic acid and the essential oil of Bitter Almonds, or Benzaldehyde, which is not used in medicine. Bitter Almonds yield from 6 to 8 per cent of Prussic Acid. About 5 lb. of the seeds yield on the average half an ounce of the essential oil.

The term 'prussic acid' owes its origin to the fact of its having been first obtained from Prussian blue. This acid is contained in small quantities in the leaves and seeds of some of our commonest fruits, especially in applepips. While it is a valuable remedy for some diseases, it is also a deadly poison and its action is extremely rapid.

The leaves of the Cherry-laurel (Prunus lauro-cerasus) owe their activity to the prussic acid they contain. The laurel water made by distillation is a dangerous poison, and is so variable in strength, that it is unsuited for administration as a medicinal agent. Several fatal cases have occurred from its injudicious use.

The once famous 'Macassor Oil' consisted chiefly of Oil of Almonds, coloured red with Alkanet root, and scented with Oil of Cassia.

This essential volatile oil of Bitter Almonds, under the name of 'Almond flavouring' and 'Spirit of Almonds,' is used in confectionery and as a culinary flavouring, but on account of its poisonous nature, great care ought to be exercised in its use, and for the same reason, Bitter Almonds and ratifia biscuits and Marchpane (made largely of Bitter Almonds) should be eaten sparingly.

Bitter Almonds and their poisonous properties were well known to the ancients, who used them in intermittent fevers and as a vermifuge, and they were also employed by them, and in the Middle Ages as an aperient and diuretic, and as a cure for hydrophobia, but from the uncertainty of their operation and the risk attending it, we seldom see them administered now. Taken freely in substance they occasion sickness and vomiting, and to dogs, birds and some other animals, they are poisonous. A simple water, strongly impregnated by distillation with the volatile oil, will cause giddiness, headache and dimness of sight, and has been found also poisonous to animals, and there are instances of cordial spirits flavoured by them being poisonous to man.

Of the several varieties under which they exist, none in size and form resembles the long, sweet Jordan Almond, and it is to avoid Bitter Almonds being used instead of Sweet that the British Pharmacopoeia directs that Jordan Almonds alone shall be employed when Sweet Almonds are used medicinally.

Culpepper says that Bitter Almonds

'do make thin and open, they remove stoppings out of the liver and spleen, therefore they be good against pain in the sides.... The same doth likewise kill tetters in the outward parts of the body (as Dioscorides addeth) if it be dissolved in vinegar.'

---Adulterations and Substitutes---The adulteration of Bitter Almonds with Sweet Almonds is a frequent source of loss and annoyance to the pressers of Almond Oil, whose profit largely depends on the amount of volatile oil they are able to extract from the residual cake.

Apricot and peach kernels contain constituents similar to those of the Bitter Almonds. They are imported in large quantities from Syria and California, and are often used by confectioners in the place of Bitter Almonds. (A very large proportion of the so-called ground Almonds sold are prepared from peach kernels, and this is the reason why in good cookery the whole Almonds are used, though the pounding is along and tedious business,-EDITOR)

The fixed oil expressed from them is known as Peach Kernel Oil (0l. Amygdae Pers.). From the cake, an essential oil is distilled (0l. Amygdae Essent. Pers.), as from Bitter Almond cake.

True Oil of Almonds is frequently distinguished from these by being described as 'English,' since the bulk of it has hitherto been pressed in this country. The kernels of the peach and apricot are with difficulty distinguished from those of the Almond, and the oils obtained from them closely resemble the so-called English, and much more expensive oil.
