INTRODUCTION.
Since ancient times, humans have used plants to heal, soothe,
perfuming, seasoning, cooking. Ancient and pre-Hispanic civilizations
They inherited their knowledge and knowledge that have been passed from generation to generation.
generation, enriching popular wisdom and scientific research.
Medicinal plants are found all over the planet, their
location and development depends on factors such as soil, water, climate,
altitude, latitude, humidity, temperature, rain and wind, among others.
Tropical countries, due to their geographical location and relief, have a great
variety of medicinal plants including endemic species.
Industries: perfumery, cosmetics, pharmaceuticals and food use plants
medicinal in many of its processes for its wonderful properties; that's why the
planting these plants in organic crops, well planned and cared for, is a
profitable opportunity, it is a promising industry, with a future, since it goes beyond

the production of the fresh plant for immediate consumption. The processes that
can be carried out with medicinal plants ranging from dehydration
to the production of essential oils, with interesting markets worldwide
national and international, adding an added value that makes it very profitable
its cultivation.
This guide responds to a need in the agricultural sector, takes a look at the
processes that are carried out with medicinal plants, some can be carried out
easily, without the need for complicated equipment or advanced technologies, other
They are produced exclusively by the industry, since they require a high investment and
more complex developments. There is here an invitation to consider the cultivation of plants
medicinal products as a viable agro-industrial alternative, easy to develop, with
interesting markets and a lot of future.
It is important to emphasize the advantage of the cultivation and use of
medicinal plants from the point of view of satisfying with them the needs
primary health care, thus reducing the strong costs that they represent for the
user the acquisition of certain commercial medicines and from the
synthetic chemistry. In the face of health emergencies in remote places, plants and
Natural medicinal products are a good option.
This booklet corresponds to number seven (7) of the series of agro-industrial booklets

WHAT IS A MEDICINAL PLANT?
Plants make two types of chemical components: the principles
immediate and the active principles.
Immediate principles are substances that do not have pharmacological activity (do not
act as a medicine) on the animal organism, they are produced by plants
food and are essential for nutrition. Within these principles
we can name proteins and lipids, among others.
Medicinal plants are the plants that produce the active ingredients, which
have beneficial or harmful activity on the body, for example: a water
aromatic (infusion) of coca leaves is an excellent digestive tonic after
a hearty dinner, while chemically processed to obtain the
cocaine hydrochloride and inhaled produces a negative addictive effect for the
body.
Medicinal plants serve to reduce or neutralize diseases, relieve and
restore lost health. Within the group of medicinal plants are
aromatic plants, spices and beekeeping.
Aromatic plants also produce active principles but these are
fundamentally essences; spices are plants that man has used
since ancient times for its characteristics to give color and flavor to food,
They are widely used in confectionery, liquor, culinary, in general in the industry
4
food; Examples of these plants are thyme, cardamom, mint, anise,
fennel, basil, mint and bay leaf; finally there are the plants
beekeeping that are those that serve for bees to make honey and other
products in the hives.
The nutrients, the type of soil, the water, the sun, the wind, among other factors, influence the
synthesis of the active principles.
.
The active principles give special characteristics to each plant and are
elaborated in it: the root acts as a pump that absorbs the nutrients of the
5
soil, the stem carries them together with the sap to the leaves that are the laboratory of the
plant, since most of the metabolism processes are carried out there; where
Compounds of different classes are synthesized. As the process of making
the immediate and active principles is carried out in the plant, it must be taken into account
account the kind of nutrients, the type of soil, the water, the amount of sun and other
variables, but above all, it is very important that the cultivation of the plants
medicinal products is natural, clean, organic, free of impurities and contaminants that
can be processed by the plant and therefore consumed by man. HE
want an organic crop because herbicides, insecticides, fungicides and
chemical fertilizers, alter the natural conditions and states of plants,
distorting and changing the useful essence of its principles and its derivatives.
MEDICINAL PLANTS HAVE A NAME, SURNAME AND A
CHARITABLE ACTION.
Medicinal plants have common names by which people know them.
or identifies, many times the names change from region to region and with more reason
from country to country; In addition, each language has a name for medicinal plants,
for this reason the botanists organized them with names and surnames in a system of
classification that allows anyone to identify the plant. the vegetable kingdom
It is divided into families, genera and species, the family is established by the
similarities of the flowers between a plant and others, within the families there is a genus
that many plants can share and finally there is the species, which
difference from their relatives. Then we have that each plant belongs to a
family, genus, and species.
May plants be your food and your food your medicine

There is a different classification to botany, according to the function that the
medicinal plants play, they can be divided as relaxing plants,
digestive, circulatory, hepatic, cleansing, respiratory, for the skin, for the
rheumatic problems, for the eyes, mouth and ear, for women and to improve the
immune system. Many plants classify into two or more groups since their
Active principles serve to solve more than one discomfort or indisposition.
There are disorders that are part of the normal development of life, they do not become
pathologies but can be managed with appropriate plant treatments

medicines, however, if symptoms continue or worsen, consult
a health professional.
Relaxing plants: are those that contribute to relaxation and recovery
of balance; anxiety, tiredness, insomnia and depression are disorders
that sometimes affect people and these plants help to overcome them. They appear
Within this group, valerian, passion flower, verbena, lemon balm, hops,
poppy, lavender and oats.
Digestive plants: they are repairing plants for digestive disorders caused by
due to an unbalanced diet and the incidence of stress. are inside
this group, ginger, chamomile, gentian, anise, fennel and pennyroyal, among
others.
Circulatory plants: they have the virtue of improving blood circulation and
various common ailments such as varicose veins. Nettle, Rosemary, Ginkgo
biloba, linden, olive and mistletoe.
Liver plants: when we eat, food follows a route that includes
to the liver and gallbladder within the digestive system; little food
adequate overload of work on these organs and generates disorders that require
careful. Nature offers milk thistle, chicory, boldo, mugwort and
turmeric to prevent or cure these ailments.
Purifying plants: they are those that act as antiseptics, diuretics and help
in problems such as fluid retention, urinary tract infections and
kidney stones. Juniper, corn silk and parsley are excellent for
help evacuate fluids.
Respiratory plants: respiratory ailments are very common, they occur
frequently and range from colds to bronchitis or asthma, the plants of

this group stimulate the elimination of toxins and contribute to the well-being of the
sick, as they often trigger a more lasting cure than that of the
drugs. Eucalyptus, plantain, elder, mallow, marshmallow, lemon, and
hyssop are excellent allies against infections, colds and coughs.
Plants for the skin are those that provide moisturizing, healing,
emollients and moisturizers for your care. Calendula, horsetail,
aloe vera, dandelion and borage are wonderful for the skin.
Plants for rheumatic problems: these medicinal plants are the basis of
many medications, relieve joint pain, back pain,
sprains and muscle pulls. They include celery, basil, cayenne, willow
white, marjoram, primrose and meadowsweet.
Plants for the eyes, mouth and ear: in these parts are located many of the
minor conditions that frequently cause oral problems, headaches,
ear and conjunctivitis can be treated with plants such as sage, mint,
myrrh, oregano and cloves.
There are plants that serve to maintain good health, help to avoid
diseases and strengthen the immune system. Ginseng, garlic and
echinacea are part of this group.

HARVEST OR COLLECTION.
It is important for the use of medicinal plants to take into account the management that
It is done from the moment of harvesting to the medicinal preparation, since
depending on factors such as harvest time, moon phase, rainy season,
amount of light, among others, the yields and the quality of the principles vary
assets.
The collection is made from the different parts of the plants such as the
root, foliage, flowers, fruit and seeds, each has moments and times
appropriate for harvesting or harvesting, which must be taken into account.
How are the flowers collected?
Only the flowers that are well open and that are not wet are collected,
that is why it is recommended to harvest them when the dew has risen and in hours of the
noon or sunset.
Some flowers, such as marigolds, are collected by cutting them below the stem.

11
The collection of flowers.
Once harvested, the flowers are placed in a clean paper bag, in
enough quantity so that they are not too tight, it is closed with a thread or
cabuya to protect them from contamination with dust or other substances and
prevent insects from arriving.
The bags should be hung in a warm, ventilated place and left for a while.
necessary until the flowers become brittle.
Bags with flowers should be tightly closed and stored in a cool place.
12
The flowers are stored in paper bags
How are the stems and leaves collected?
The stems are collected with leaves, they are tied and once the ties are done, they are hung
down in a dry and ventilated place, away from direct sunlight.
Collection of stems and leaves.
13
When the leaves have dried and become brittle, they are removed and shredded.
The shredded leaves are kept in a dark colored jar tightly
cerrado.
The dried leaves are stored in dark, wide-mouthed, marked jars.
Leaves that are high in moisture or thick like comfrey
minor, the borage and the plantain are dried a little in the oven at a medium temperature or
lukewarm for about two hours and then crumble and store.
Like vegetables, medicinal plants are best when fresh, but
can be dried and then stored in tightly closed containers,

formed and are drying; to collect them, the branches with fruits are hung towards
down on a cotton cloth tray or can be placed in a bag
of paper and hang them so that the seeds when detached fall into it.
How are the roots collected? After removing the root of the plant, it is soaked in cold water for an hour to
remove dirt and dirt. Once clean, the large root is cut

THE EXTRACTS.
The extracts are pharmaceutical preparations that, due to hygienic conditions and
preparation in its manufacture and packaging are carried out in laboratories
specialized, but at an informative level it is equivalent to preparing a juice, in which
add distilled water or another medium and medicinal plants. It is usually
they consider three types of extracts (according to Thomson);
• Fluid extracts that are those in which the volume of the liquid of the extract is equal
to the volume of the dry plant that has been used.
• The soft extracts, which are those in which the water has been partially removed.
until it has a consistency of ointment.
• The dry extracts, which are those from which all the water has been removed and
its appearance is that of a very fine powder.
This type of extracts whose process consists of drying the plant, pulverizing it and
Encapsulating it is an ideal method of managing bitter-tasting plants.
16
In phytotherapy different types of extracts are mixed to obtain the therapy
desired medicinal product and are usually presented in the form of elixirs, essences and
alcoholic
DYES AND THEIR PREPARATION.
They are the extraction of the active principles of the plants by means of alcohol
ethyl, ether, a mixture of both, or liquors such as wine, vodka, brandy, pisco or
good quality gin.
Great care should be taken when purchasing alcohols and liqueurs for tinctures,
Well, if they are bought in unreliable places, that do not comply with legal regulations
may be adulterated with methyl alcohol (methanol) which causes very
serious to the human being (from blindness to death). should not be consumed
denatured ethyl alcohol, methyl alcohol, or isopropyl alcohol because they are
toxic.
The preparation is done in a very simple way: by soaking or by maceration.
Preparation by soaking.
It is the technique similar to that of the aromatic liqueurs of the grandmothers, in which the parts
whole used plants, fresh or dried, are left to soak for
several weeks. You can use a ratio of 125 grams of dry herb or 300
grams of fresh herb for 600 milliliters of vodka, or half a liter of a mixture to
25% alcohol and water.
Then the plants are removed, strained and the tincture obtained is stored in bottles,
preferably amber in a dark, cool place.
17
Preparation of the tincture by soaking.
Preparation by maceration.
Once the plants have been chosen, the maceration is done with mortar or stone and
then it is mixed with alcohol or liquor, leaving it to rest for a while so that it
decant.
Then it is filtered and bottled in the same way as in the previous case.
A tincture in good storage conditions can last up to 2 years
without losing its properties.
18
Precautions with tinctures.
Special care should be observed in handling tinctures with people
diabetics, alcoholics, children and pregnant women. It is convenient the
dilution of absolute or high-grade alcohols in very pure water. The
liver conditions should not be treated with this type of application.
Except these indications, taken in moderate doses, 5 milliliters (1 teaspoon)
three times a day dissolved in water or fruit juice sweetened with honey, tinctures
They are very pleasant to the palate and it is a very effective and simple method.
to take the principles of most aromatic and medicinal plants.
THE INFUSION, TISANA OR AROMATIC WATER.
It is the simplest and most common way to use medicinal herbs, it is very
used to cure ailments such as flu, indigestion or nervous breakdowns,
They are usually used after a large meal or in the hours
in the afternoon replacing tea. It can be drunk hot or cold.
The infusions are easily prepared:
Preparation of an infusion
19
Take a few grams of the fresh or dry plant, different parts can be used:
flowers, stems, leaves (this depends on the plant to be used, for example: mint is
they use the leaves, of the camomile the flowers or of the celery the stem and the leaves).
The plant is placed in a container and water is added almost to the point of
boiling (boiling water is not used because steam carries off much of the
volatile oils and valuable plant properties are lost).
The infusion is strained and consumed.
Let stand 5 to 10 minutes covered with a small plate or in a teapot,
strain and consume. They are generally prepared daily so that they do not lose
its active ingredients, that is, they can last 24 hours and can be consumed cold or
hot.
THE DECOCTION.
This is a stronger way of obtaining the active constituents of a plant, it is
done by placing a few grams (two teaspoons of dried herbs per cup of
20
water) of the plant (dry or fresh) in cold water and brought to a boil during the
time required for it to be reduced by one third.
Then it is strained and can be consumed hot or cold. The decoctions are very
used with roots, seeds, branches and stems, but also with leaves and flowers,
They have a 24-hour shelf life and must be prepared daily.
Preparation of a decoction
Extracts, decoctions and infusions can be used to prepare
compresses; that consist of soaking a piece of cloth (it can be linen or
cotton) in one of the previous preparations mixed with water, drain it and
apply it on the affected area (the head, an arm for example). The compress is
change once it cools down or dries out.
An action similar to that of the compress is that of the poultices, the
difference is that in these the grass extends directly over the area
affected. The fresh grass is cooked well, in such an amount that it covers the
21
affected, it is drained and applied hot on the affected area, to which
An oil has previously been applied so that the grass does not stick. To set
the poultice can be used a cotton bandage or gauze.
THE SYRUPS
Preparation of syrups.
They are a way of preserving infusions and decoctions, honey or
sugar (possibly unrefined). Usually the same amount of
infusion or decoction and honey or sugar, shake with a wooden paddle, dissolve
well to the consistency of syrup, let cool and store in dark jars.
The most widely applied syrups are those prepared for coughing, they are very easy to
take and it is an easy way to give it to children.
22
LOTIONS AND THEIR PREPARATION.
Lotions are a water-based mixture that is applied to the skin as
remedy to refresh or soothe inflammations or irritations. Some lotions are
they add tinctures or essential oils to intensify their cooling effect.
The preparation varies according to the mixture to be made, but a lotion
It could include rose water, tincture of arnica, and lavender essential oil.
OINTMENTS AND THEIR PREPARATION.
They are a way of taking advantage of the healing properties of some plants in the
skin, to treat wounds, burns, bruises and spills. The basis of the
ointments is Vaseline or beeswax, contrary to cream, they are not
absorbed by the skin, they form a protective layer on it. They are very well known
Arnica ointments for muscle aches and calendula ointments for
Burns.
The preparation is very simple: the vaseline is heated in a container in a
pot over low heat, add the herbs, mix well with a spoon of
wood and keep on low heat for about two hours or until the herbs
they are crunchy.
Using rubber gloves as the mixture is hot, it is filtered and packed in
perfectly clean dark jars.
For any of these preparations the highest hygiene should be observed.
possible and choose the appropriate containers, preferring enameled, glass
refractory, stainless steel and avoiding iron, aluminum and alloys that
can cause health problems.
23
You can use 500 grams of Vaseline and 60 grams of dried plant.
Preparation of ointments.
CREAMS AND THEIR PREPARATION.
Unlike ointments, creams seek rapid absorption of the
properties of plants as a whole of base oils and essential oils
that make it up Creams usually treat some problems
dermatological such as dermatitis, fungi, cellulite problems, varicose veins among others.
The preparation is a little more complex than that of ointments because it is a
mixture of water with fats or oils, however one way of preparing a
natural cream consists of:
24
Melt the wax, which can be from bees, and mix with water in a container at
water bath, add the herbs (for example calendula petals) and
heat for about three hours over low heat.
Then it is filtered and constantly stirred until it cools down, to finally
pack it with the help of a small spatula in preferably dark jars.
Preparation of the creams.
INFUSION OILS.
Plant active ingredients can be extracted into oil for use
in massages, creams and ointments. They can be prepared hot and cold and
They have a shelf life of one year.
Cold infused oils.
The procedure consists of filling a bottle tightly packed with the flowers and leaves.
large with a screw cap, and then a good quality oil is poured such as
garlic, grapes, olives or wheat germ until covered.

The bottle is left at rest, shaking daily for a period of not less than one month.
in a cool and dark place. It is then filtered by thoroughly squeezing the vegetable matter and
It is stored in a sterilized jar.
Cold infusion oil preparation.
This process is repeated using new plant matter and the already infused oil.
prepared.
Hot infusion oils.
This method is similar to the previous one but more suitable for working with
moist, fleshy or juicy herbs such as borage.
To make an oil by hot infusion, it is placed over low heat, in a bath
of Maria vegetable oil with dry herbs. It is then strained through
a bag or household filter and store in a cool, dark place. Can
be kept for a year. The proportion is 500 ml. of oil (can be
sunflower) per 250 grams of dry vegetable matter or 750 grams if it is fresh.

ESSENTIAL OILS; EXTRACTION PROCESSES.
Aromatic plants are a group of medicinal plants that produce all or
partially its active principle in the form of essence. aromatic plants have
multiple applications ranging from the well-known infusion to distillation for
get the essential oils.
The essential oils of aromatic plants are a mixture of substances
aromatic concentrated in the form of tiny drops in different parts of the
plant: the leaves, the root, the flowers, the stem and the seeds. For example, when taking
a tangerine or orange peel and press it, you see a few tiny letters come out

it is a mixture of many compounds. Essential oils are unique, volatile,
insoluble in water and have many therapeutic properties; have great
application in aromatherapy, in the industry of cosmetics, perfumes and the area
pharmaceutical, among others.
Essential oils are highly concentrated substances, so they must be handled
With precaution. Very pure oils should be used, never adulterated, diluted in
a base oil in a percentage that can vary between 1 and 10%, depending

29
of the application (for example for body massage the dilution can be maximum
at 3%), should not be ingested, should be kept in a cool, dark place, out of
out of the reach of children.
For essential oils to be effective, the plants from which they are obtained
must come from organic crops, cared for and collected with care and
attention, often in the trade are essential oils that
essentials have only the name, leaving much to be desired in terms of their efficiency and
therefore devaluing them as products with a great potential of
application.
Depending on the application, the kind of plant and the part that is used for the
extraction of essential oils, there are several extraction techniques, being
those obtained by steam stripping the highest quality for medicinal use and
therapeutic because it does not contain residues.
Steam distillation method.
It is the simplest of the methods and resembles the obtaining of liquors in the
old stills. This method takes advantage of the property that the
water molecules in the vapor state to associate with oil molecules.
The equipment is very simple (see graph): it requires a steam generator that
it can be a simple pressure cooker or a boiler; a reactor or chamber
extraction which is an airtight container with an inlet and a steam outlet
where plant material (leaves, flowers, wood, seeds) is deposited, a
condenser, where the vapor is transformed into a liquid again and is collected in
a container called a Florentine glass which is a glass with a detachment that
facilitates the separation of water and oil.
30
The extraction is carried out when the pressurized steam comes into contact with the
cells of plant parts and breaks them, releasing the essence and trapping it
in the water droplets of the steam which then condenses in the still.
The oil obtained through this procedure is of high purity and only
requires a redistillation to finish eliminating some drops of water that
They can get trapped in the oil.
Steam distillation method.
The essential oils obtained with this technique are widely used in treatments
medicinal, homeopathic and aromatherapy. For example, essential oils
Anise and mint are used as flavorings and lavender in perfumery.
Pressed, screwed or expresión method.
It is the most used method to extract the essential oil found in
housed in the peel cells of all citrus fruits (orange, tangerine,
pomelo, lime).
The procedure consists of taking fragments of the shell and squeezing them between the
fingers against a sponge. After many peels and a lot of patience, the
31
sponge is saturated with the essential oil and can be squeezed into the container that is leaving
store. The quality of the oil thus obtained is good. Industrially it is used
a hydraulic press and then it is filtered and distilled, but the quality of this oil is
inferior.
Method of pressing or expression.
Efleurage method.
It is an ancient technique, in which animal or vegetable fats are used for the
essence extraction. It consists of large grease-smeared trays on which
plant material is spread, which is changed regularly until the
fat is saturated. The fat thus obtained is treated with alcohol which is then distilled to
get the gist. It is a good alternative although it does not give great yields,
since it is a simple way to extract the essential oil of the flowers and of
some plants that cannot be obtained with steam stripping.
32
Industrial method of extraction by carbon dioxide.
It is a similar method to steam stripping but instead of water it uses carbon dioxide.
carbon to blow up the cells. The oils obtained in this way are
of very good quality but requires equipment, assembly and
large and expensive infrastructure so it is generally used by industry
pharmaceutical.
Industrial solvent extraction method.
This method takes advantage of the property of the aromatic parts of the
plants to dissolve in some solvents from which they will later be separated. Of
In this way, the fragrances of some flowers and resins such as myrrh are obtained.
It requires a laboratory with technology and it is found as an inconvenience the
that the solvent cannot be totally separated, so the essential oil
obtained is not pure. The extractions obtained are used basically in the
perfume industry.
USES AND APPLICATIONS OF ESSENTIAL OILS.
The consumption of essential oils in the industry is very varied and ranges from
aromatize soaps and shampoos to the elaboration of food and perfumes.
According to estimates by the World Health Organization, at least 80% of
the world population depends mainly on medicines and treatments
natural. Even in industrialized countries, 40% of drugs come from
Natural sources. Many medicines are made from ingredients
natural and others are synthetic copies or artificially modified varieties of
natural chemicals.
Most of the medicines have their origin in the compounds of the
plants
33
In the pharmaceutical industry.
This is one of the branches of the industry that consumes essential oils, in
both allopathic and homeopathic preparations. This is how the eucalyptus is
used in syrups for respiratory conditions and rosemary and arnica for pain
rheumatic or muscular
Agro-industrially there is an unexploited potential, since it is possible to carry out
prepared with both essential oils and hydrosols to repel
pests or control damage caused by fungi or viruses, since aromatic plants use their
essential oils as a defense to protect themselves from the attack of insects and insects
diseases. Chamomile is used with great success for gout attacks in the
potato and tomato, and garlic and chili against the potato fly and the fly eaters
leaves.
Pharmaceutical applications of essential oils: hydrosols, syrups and creams.
34
Veterinary preparations can also be made with rosemary and lemongrass to
control insects such as the nuche (horsefly) and fleas.
In the cosmetic and perfume industry.
Soaps, perfumes and scented waters are some of the products that can be made
for the cosmetic industry.
In the cleaning products industry, lemongrass and lavender are used to perfume
and disinfect. In the fine soap industry, the aroma of soaps is a mixture
of fragrances and essential oils of flowers, woods and aromatic plants. The
manufacture of shampoos uses the properties of medicinal plants and
