The role of medicinal plants in the contemporary world

Plants have been used for medicinal purposes since ancient times . Old documents of ancient China and Egypt describes the use of medicinal plants since 3000 BC African and indigenous cultures have used North American plants in their healing rituals , while other cultures have developed traditional medical systems such as Ayurveda from India and Traditional Chinese Medicine . Modern research has shown that people in different parts of the world tended to use the same parts of the plants to get the same therapeutic effects.

In the nineteenth century, when chemical analysis have been widely used , scientists began to extract and modify the active ingredients from plants. Later, chemists began to produce their own version of plant compounds , and over time, the use of herbal preparations declined in favor of synthetic drugs . However, it should be noted that almost a quarter of the current medicines are derived from plants.

Recently, the World Health Organization estimated that 80 % of people around the world trust and use herbal preparations in primary care . In Germany , about 600-700 plant based medicines are publicly available and are prescribed by approximately 70% of German physicians . In the past 20 years, United States , public discontent over the high cost of chemical synthesis drugs issued on prescription , combined with the public’s legitimate interest in returning to natural or organic remedies , has led to a increasing consumption of herbal preparations .

Whole herbs contain many ingredients that act in synergy to produce a more pronounced effect . You must remember that there are many factors that determine the effectiveness of herbs. For example , the type of environment ( climate , insects and soil quality ) in which a plant germinated and developed , how to harvest and processing can influence the therapeutic effects of this herb.
Often plants can be used together, and their combinations increase the therapeutic value and have fewer side effects. Health care providers should consider several factors when recommending certain herbs, including the species , habitat , storage and processing , and the absence of contaminants (including heavy metals and pesticides ) .

Most herbal preparations are available in pharmacies or specialized commercial networks in several forms of presentation, such as teas , syrups , oils , liquid extracts , tinctures , and dry extracts (in the form of tablets, pills or capsules ) . Teas are obtained by infusion or decoction . Syrups are made from concentrated extracts are added colors, sweet ingredients . Tinctures and liquid extracts are obtained from fractions dissolved in a liquid (usually water, alcohol , or glycerol) . Dyes with a dilution of 1:5 and 1:10 , which means that part of the plant is prepared with 5 to 10 parts ( by weight) of the liquid . Liquid extracts are concentrated as dyes and usually at a concentration of 1:1 . The dried extract is the most concentrated form of an herbal product . In this case the degree of dilution is usually comprised between 2:1 and 8:1 , the final made ​​production is sold in the form of a tablet or capsule .

Most of the plants used in food supplements are grown in specialized farms . Other species can be collected from the spontaneous flora . Among the countries which produce and export substantial quantities of herbs can include: India , China , Thailand , South Korea , Brazil, Mexico , Egypt , Indonesia , Nepal , the Philippines and Kenya. The countries of Eastern Europe , especially Romania , cultivate herbs mostly for their own consumption .

After the plants are harvested , they must be cleaned manually . In some cases , they are used fresh, but , in general , they are dried to reduce moisture content and to facilitate storage. Follow the extraction process , a process by which a plant ‘s active ingredients are separated using a solvent. Once an extract was obtained , manufacturers can use a series of tests to assess the quality and purity of their product. First, one can examine the physical characteristics of the extract , including the organoleptic evaluation , the pH , the solubility , the total solids content , ash content, and in the case of the extracts , even the particle size .

When referring to the popularity of various herbs, we must mention that herbal supplements with the highest sales in the U.S. include Echinacea purpurea , St. John’s Wort (Hypericum perforatum) , ginkgo ( Ginkgo biloba ) , garlic (Allium sativum ) , palm dwarf ( Serenoa repens ) , valerian ( Valeriana officinalis) and Feverfew or flower girl ( Tanacetum parthenium ) .
For the previously mentioned romaaneasca Ethnomedicine herb known as flower girl , we present in the following story species Tanacetum parthenium .

It is a perennial plant belonging to the family Asteraceae prevalent in gardens and roadsides . Popular name in Anglo-Saxon space and feverfew is derived from the Latin word which indicated febrifuge property to lower fever.
Native to the Balkan Peninsula , the species is now widespread in Australia , Europe , China , Japan , Africa and North America . The ancient Greeks called the plant ” parthenium , ” because they used it as a medicine to save the life of the fallen from the Parthenon during its construction in the 5th century BC

The species was known as ” aspirin medieval ” , and the remedy of the eighteenth century, being used to improve disorders associated with arthritis , asthma , constipation , dermatitis , fever , headaches and migraine inflammatory conditions .
If we refer to migraine , it should be noted that this is considered the 19th leading cause of disability in the world and the 12th leading cause of disability among women.
The World Health Organization believes that a person suffering from a severe migraine attack has a similar degree of disability the patient with spastic quadriplegia , with a much greater degree of disability than a person without sight.

Sun Wave Pharma is supporting patients in Romania and the medical and pharmaceutical community offering Migrolin – solution for improving the quality of life of patients with migraine .

Migrolin reduced frequency, intensity and duration of migraine attacks and relieves associated disorders and migraine headaches . The daily dose is 2 capsules per day , one capsule containing 10:1 extract dress flower ( Tanacetum parthenium ) at least 0.5 % parthenoide .

Modern research conducted in the laboratory have identified and isolated the key ingredients of the species , ie sesquiterpene lactones ( most of these lactones are parthenolidele ) to have an anti-inflammatory , anti-migraine antispasmodic and antirheumatic
