Oregano marjoram or simply marjoram (Origanum majorana L., 1753) is an aromatic perennial herbaceous species used both in cooking and for therapeutic purposes.
Origins and History –
Oregano marjoram is a plant native to the Middle East and grows spontaneously and easily in loose and calcareous soils, preferably well exposed to the sun. It is also called by the name of persia or persia grass by the Ligurians, probably to underline, besides its origin, the loss of the plant every time it is left without care.
Marjoram is a plant known since classical times; it was considered one of the symbols of happiness, and we find it widely used in the kitchen both by the Romans and in the following centuries.
An ancient treatise thus speaks to us: “It is perhaps because of the pleasantness of its smell that marjoram is a plant so grateful to women, that there is hardly any that does not plant and care for it diligently in vegetable gardens or in pots … distilled marjoram juice, introduced into the ear in small quantities, eliminates pain and annoying wheezing and helps with deafness; sucked by the nose, it removes phlegmatic humor from the head, purifies and comforts the brain “.
In the food sector, marjoram is one of the most used aromatic herbs in all of Europe. It is suitable for all those dishes where a strong and at the same time rather sweet aroma must be obtained. However, its scent is affected by heat, therefore it must be added raw or cooked. It is the ideal condiment for pizzas, mixed salads, raw sauces, vinegars and aromatic oils.
Marjoram is a perennial herbaceous lignified plant in the basal portion, very aromatic.
It has an erect, widely branched stem, up to 50 cm tall, with a square section, initially tomentose and ash green, then glabrous, with oblique rhizome.
The leaves are opposite, with obtuse or rounded base, from oval to oblong (generally 5-10 x 8-20 mm), they shrink at the base in the short petiole and have a rounded apex; the margin is whole, the surface of the younger leaves is whitish due to the presence of a thick hair.
The flowers are sessile, have a tubular and bilabiate corolla (whole or almost upper lip, the lower one divided into three acute lobes), with white-pink or sometimes purplish petals, are gathered in dense glomeruli forming racemes at the top, characterized by round bracts , tomentose and glandular, stamens with divergent filaments and often anthers protruding on the sides; chalice with 5 teeth, faintly cheekbone tubular (cone-shaped open on one side).
The fruit is a microbasial (tetrachenium enclosed in the bottom of the persistent calyx), with 0.9-1.3 x 0.7-0.8 mm mericarps, ellipsoids, with acute apex, first yellow then dark brown in color.
