Medicinal plants grow in the desert in small numbers and at certain times of the year when conditions are favorable
These plants store water in some of their parts to cope with drought, so mutations occurred in these parts to suit the function
Formation of stems and succulent leaves to store the largest amount of water
The leaves are small in size to reduce the amount of transpiration
The leaves and stem are covered with a layer of chitin to reduce water loss
Leaves and stem are either light colored or mottled green to reduce light absorption
The stomata are few in number and close during the intensification of heat. They may be covered with waxes and resin and are sunken under the epidermis
The concentration of cellular juice in the root hairs is high to facilitate the absorption of water from the soil
The branches are short and close to each other in the form of a small cushion, which protects the plant from direct sunlight
Placing the leaves on the stem is vertical and parallel to the stem, as well as the blade is small and the neck is flattened
The leaves may be completely absent and the stems are flattened and replace them in the post
The plant stores water in special tissues in the middle and away from sunlight to prevent water loss
The roots are deep and extended in the soil to reach groundwater

Medicinal and aromatic plants continued to be used as they were until the science of chemistry and physics appeared, so it was possible to extract the active substance from them and increase its concentration to maximize its utilization.
With the spread of many diseases such as kidney failure and liver disease, the demand for the use of medicinal plants increased
The only source of these plants was their collection from places of their natural growth, such as mountains, forests, and deserts, and this amount of plants was sufficient because the population was small and there were few diseases at the time, but with industrial progress and the migration of people to cities and the spread of pollution, the demand for them increased.
The development of biology led to the study of these plants and the identification of ways to propagate them in an environment other than their own, and in quantities sufficient for the growing population.
Many of these plants grow in desert areas, so it is easy to expand their cultivation without affecting the areas available for growing strategic crops.
It has now been possible, using the technique of genetic engineering and tissue culture, to propagate these plants inside the laboratories and extract the active substance using what is called bio-fermenters or bio-reactors by providing the appropriate conditions for cultivation and cloning inside the laboratory.
However, these techniques are very expensive and are used only in the production of high-priced materials
There are also strong objections in Europe and the United States that prevent the consumption of materials derived from agricultural engineering, which increases the demand for natural medicinal plants
It is everything of plant origin and is used medically and contains active substances and has a physiological effect
Plants that contain aromatic substances in their parts
The plant kingdom contains many species that have medicinal properties, called medicinal plants, and others that have aromatic properties, called aromatic plants.
Benefits of medicinal plants
Cultivation of medicinal plants helps achieve self-sufficiency and bring in hard currency
Medicinal plants are used in the pharmaceutical industry as well as in folk medicine, which helps in the treatment of many diseases
It can be cultivated in newly reclaimed lands, which works to provide the current agricultural area for growing strategic crops
They participate in the agricultural cycle, which prevents dependence on one crop
It can be exported dried or extracted materials can be exported
Other aromatic substances
Spices found in cooking, such as coriander, chili, cumin, and others
Food and drinks such as star anise, fenugreek, cinnamon and ginger
Flavors and aromas such as fennel, star anise, mint, rose and jasmine
Cosmetics such as rose, jasmine, violet and tuberose oil
Insecticides such as Aldres, Pyrethrum and Tabaq
Rodent killers, such as red onion
Fixed oils such as sunflower oil, corn oil, and black seed oil
Dyes and coloring materials such as hibiscus, henna, calendula, and chamomile
A source of vitamins, minerals and mineral salts such as garlic, lettuce, onions, spinach and carrots
