For the most part, growing lavender in Croatia comes down to small producers who make it an extra household income. Collecting lavender is the most important part of production because it provides raw material for later processing. Manual harvesting of lavender generate its yield as only the top part of the plant with the highest concentration of essential oil is harvested. The problem with mechanical harvesting is that the machine is not so precise and cannot be adjusted to collect only the top parts of the plant.
Medicinal sage is an native plant species of Dalmatia spread throughout the Mediterranean. In the Republic of Croatia along the entire coast, as well as in the entire Dalmatia. Sage is first and foremost a medicinal plant, but it is also used as a spice. In Dalmatia, sage was used long before the classical period, in the nature its leaves were collected from which essential oil was obtained, and the beginnings of cultivation date to the early 20th century on the island of Hvar. Today in Dalmatia there is no production of dried leaves and essential sage oil, except to a lesser extent on...
In the past, herbs were the only cure for the disease, and learning about herbs was based only on human experience. They found the medicine in their environment, where they learned to recognize the plants and to determine how to use it. Knowledge and experience have been passed down from generation to generation, so today there are many who, thanks to the knowledge and experience of their loved ones, have become successful users and growers of medicinal plants, although unfortunately some of the knowledge about medicinal plants has probably fallen into oblivion, given that no one ever...
This study presents an assessment of essential oils amounts and quality obtained from Tunisian Salvia officinalis and its variations regarding the plant organs, the harvest season and the plant's drying process conditions. Three drying processes were tested, natural air drying, hot air convective drying at two temperature 40 and 60°C and microwave drying at 218 W.
One of the preconditions for successful cultivation and increase of production of medicinal and aromatic plants in Croatia is in any case knowledge of their ecological characteristics. However, previous studies of medicinal and aromatic plants in Croatia have not systematically included the islands of Krk, Cres and Pag, despite the fact that these islands are areas of plant richness. Therefore, the aim of this paper is to determine the abundance and diversity and ecological characteristics of wild medicinal and aromatic plants of the rocky pastures of these islands.
The aim of this work was to evaluate the effect of treated wastewater short and long-term irrigation on essential oil composition from E. camaldulensis Dehn in order to detect allelopathic impacts on seed germination and seedling growth of Amaranthus hybridus L, Chenopodium album L, Echinochloa crus-galli (L) Beauv and Lolium perenne L as important weeds on many crops.
Wild species must be recovered and their uses incorporated daily as normal. We must document the traditional uses of vegetation and promote actions aimed at citizens to publicise them. The research and dissemination axes are essential, but they must be accompanied by the development of business models that also allow the commercialisation of products. In Catalonia (Spain) there are several associations and companies that work to value them, either in the gastronomic field or as a tourist activity.
In Tunisia all forest areas are public: in order to use forest products, producers and firms should go through a tendering system subject to Article 18 of the Tunisian forestry code, organized each year by the Tunisian Forestry authority. Small firms and the local populations are facing many difficulties to use available resources legally. The DGF is promoting a new form of sustainable management for forest resources: Concluding contracts between the organized local community and the administration to improve their livelihood and to protect forestal areas.
In the Doñana National Park in Andalusia, short-rotation coppice eucalyptus plantations occupy large areas and belong to private forest owners.
« Esencias Garcia-Palomo » distillery uses 5,000 kg of eucalyptus branches and leaves every day for its production of 10 to 40 kg of essential oil. Not being a forest owner, this resource is a cost to the company.
Mr. Palomo has organized with his neighbors to work in symbiosis and limit the costs of their respective operations : the collection of his raw materials contributes to the silviculture of coppices of eucalyptus.
The role and importance of organic production lie in the sustainable management of natural resources (preserves soil fertility, flora and fauna, water and atmosphere), forbids the use of chemical means of protection and fertilizers, restoring balance to nature and thus preserves biodiversity, encourages rural development and facilitates the development of small family farms, contributes to the development of eco-tourism and eco-villages and thus links agricultural, tourism and craft activities.
A multi-stakeholder approach has been initiated in the Hautes Vosges on stubble in the Markstein - Grand Ballon sector to preserve the resource of Arnica montana ssp montana and its natural habitat (the "high stubble"), to maintain the economic issues that represents its picking, while reconciling the other uses of high altitude grasslands where this plant grows : cattle grazing, grass harvest, outdoor sports (skiing, gliding).
Private forest is often very fragmented: forestry operations and forest products marketing are difficult on small areas. Owners have organized themselves into a forest management association (ASLGF) to group their plots into a single management unit. Their objective is to jointly lead the development of their forests. In addition to harvesting wood, they also registered collective production of essential oils of Scots pine. They wish to label themselves as a Forest Economic and Ecological Interest Group (GIEEF).
Among essential oils, Eucalyptus oil, is one of the most useful as it is easily extractable commercially (industrial value) and possesses a wide range of desirable properties worth exploiting for pest management. Eucalyptus oils are mainly extracted from leaves which can be attacked by gall wasps as Ophelimus maskelli. Induced galls can affect the essential oil production.
This work aims to determine the role of the parasitoid Closterocerus chamaeleon in the biological control of its host O. maskelli.
The production of medicinal and aromatic plants (MAPs) from wild collection or by cultivation raises environmental, social and economic issues. The demand for a wide variety of wild species is increasing with the growth of human needs and trade. There is an awareness that many wild plants are being overexploited, which many experts recommend incorporating into cropping systems, but several aspects that determine their viability have to be taken into account. An alternative is small-scale cultivation.
During the last years there has been a growing interest from young people to get involved in the AMP exploitation business. The rich Greek flora and the plenty of abandoned agricultural fields in rural areas offer a great potential in this direction. However, most of the young farmers/entrepreneurs didn’t have a relative experience in the field and there has been many fails and disappointments.
Pine species are considered as a natural source of antioxidant compounds. Pinus nigra Arnold is one of the most known medicinal plants in the Mediterranean countries. The aim of this study was to determine, for the first time, the bioactive compounds such as the total phenols, flavonoids and tannins and to evaluate the antioxidant potential of needles collected from nineteen samples corresponding to different provenances of black pine from different regions which have been planted and grown in Northwestern Tunisia.
Nature has been the source of aromatic plants and herbs for thousands of years, and their use as medicines, enhancers of food aroma, preservatives, or cosmetics is well known from antiquity. However, the great development of animal product industry, in combination with the growing consumers’ demand for higher quality and more environmentally friendly products during the later years, led the food industry to begin to search for alternative solutions in animal nutrition. The introduction of aromatic plants as natural feed additives can be considered as one of them.
Identify drivers and barriers for developing the Tunisian Essential Oil market and new growth strategies to promote the sector and become more competitive in the international market.
Electric power production from coal combustion still accounts for a great proportion of total energy production in Europe. The Public Power Corporation S.A is the largest power producer and distributor in Greece and for more than 70 years manages a great coal mining area, the Lignite Center of Western Macedonia. The coal mining procedure leads to the formation of disturbed lands in coal mines, mainly in the places of soil depositions, the implication of a viable reclamation practice of whom is very critical.

The project objective was to identify chemically different Rosmarinus officinalis wild populations present in the Spanish geography in order to be able to choose those that present a higher essential oil concentration with an interesting chemical composition for the industry uses.
Identify these wild populations is the starting point for initiating any breeding program to obtain commercial varieties that can be put into large scale cultivation to satisfy quantity and quality industrial demand.
The current exploitation of rosemary and myrtle (native species with relatively high yield of EO) occupies an important place in the forestry sector and a significant socio-economic interest. Eucalyptus trees can play a predominant and substantial role thanks to their richness in essential oils, their composition and their commercial value.
This objective necessarily involves the identification of eucalyptus EO species and the selection of the most efficient in terms of the yield of essential oils and the presence of the most dominant active compounds which are preferentially sought...
The Yellow Gentian (Gentiana lutea) is a wild plant harvested for its roots at the age of 20 to 30 years old. It is highly valued but little protected. A large part of the production is exported from the source in its raw state. The "Mission for the sustainable management of gentian resources in the Massif Central", a project promoted by the harvesters, helps the different members of the sector to organize themselves to work on good production practices and to ensure the sustainable use of the plant. This work is enhanced by a parallel project to create a "Sustainable Gentian"...
Purslane is known for her gastronomic and medicinal excellences effects. It is considered a miraculous plant with healing properties (Hwess.H et al., 2017). It is very used in traditional medicine, but not well exploited in the pharmaceutical industry. In order to raise awareness also on this wild plant, we have decided to compare many provenances of puslane, using maceration extraction.
AFC is the French Association of professionals wild plants pickers. It was created in 2011 to bring together professionals of wild plants picking and to promote this profession.
It defends sustainable commercial harvesting and a responsible profession.
