Our ingredients

The natural active ingredients that we use derive from four primary ingredient groups:

Ingredients inherited from our pharmacy days / Calendula, Echinacea, Hypericum, Evening Primrose

Plants that have evolved adaptations to grow in Greece’s unique environment / Thyme, Sage, Bay Laurel, Olive, Mastiha

Beneficial ingredients with advanced skincare properties including Yoghurt, Thyme Honey

Actives such as natural antioxidant Quercetin, with proven efficacy as per the findings of international research programmes including the primary research carried by the Korres Research & Development Lab.


Wild rose is probably the most popular flower in the world. Wild rose oil, rich in linoleic and linolenic acid, demonstrates significant healing, moisturising and softening properties. At the same time it forms a protective film on the skin that helps the cell regeneration and improves the texture of the epidermis. Furthermore, the wild rose fruit is noted for its high vitamin C level that demonstrates significant repairing activity to fine lines and skin colour disorders.

The Pomegranate extract is a rich source of tannins, anthocyanins, vitamins (A, C, E) and minerals and is widely used for its antioxidant properties. The pomegranate fruit contains three times the antioxidant properties of red wine or green tea. This high level of antioxidants found in pomegranate is effective in combating free radicals that cause premature ageing of skin cells. Pomegranate extract has also significant astringent properties, due to the contained tannins. As a result, it tightens the pores and strengthens the skin epidermis, thus being ideal for oily and combination skin.

Achillea’s use in traditional medicine has been recently boosted by medical research. Achillea has significant antibacterial and healing action. Its skincare role is important, as its white dried inflorescence is suitable for looking after sensitive skin. Amongst its properties, oiliness regulating and hair revitalizing.

Plant Power

The ever so appealing romance of Nature in the role of the ultimate provider; Eve in the Garden of Eden tempting Adam to eat from the Tree of Knowledge; Homer referring to the ‘pomegranate breaking’, a tradition that has survived until today due to the fruit’s association with life, fertility, passion and power; Socrates sentenced to death by drinking a lethal blend containing hemlock poison; the Grimm Brothers’ Rapunzel, named after the rapunzel, a plant of ‘discord’; "la fée verte" or green fairy in French, the anise-flavoured spirit – Absinthe – derived from the herb Artemisia absinthium, associated with Parisian artists and writers.

Healing, calming, toning, seducing; the power of the plants has been an area of study from early on; the Greek physician Hippocrates, also known as the father of medicine, refers to a vast number of medicinal plants in his writings. Fast forward to the Golden Age of Botany, a time when botany was a branch of medicine and practiced almost exclusively by doctors and surgeons; Vis Medicatrix Naturae, the healing power of nature in Latin. Fast forward to the KORRES homeopathic remedies archive, with over 3,000 natural remedies, based on plants.
All our formulations are developed based on natural ingredients.

Plant Hunting

The collection of live plant specimens from the wild, sometimes referred to as plant hunting, is an activity that has occurred for centuries.The earliest recorded evidence of plant hunting was in 1495 BC when botanists were sent to Somalia to collect incense trees for Queen Hatshepsut. The Victorian era saw a surge in plant hunting activity as botanical adventurers explored the world to find exotic plants to bring home, often at considerable personal risk. These plants usually ended up in botanical gardens or the private gardens of wealthy collectors. Prolific plant hunters in this period included William Lobb and his brother Thomas Lobb, George Forrest, Joseph Hooker, Charles Maries and Robert Fortune.

A team of experts led by the KORRES plant hunter, Orestes Davias a botanist with a real love for nature and plants. Driven by his passion, the richness and diversity of his native flora, Orestes searches for ingredients that provide the base for all KORRES formulations. He travels all over the world, yet the focus of his ongoing quest is the Greek flora. Considered to feature the wealthiest flora per square foot, Greece is the ideal starting point for Orestes’ plant adventures.

Our plant hunting does not go against nature. Protecting and safeguarding endangered natural ingredients is a priority. The plant hunting team, consisting of botanists, agriculturists, chemists, chemical engineers and pharmacologists work towards sustaining plant populations while mapping the native flora.

Greek flora

Greek flora is renowned for its wealth as it numbers over 6,500 varieties, 1,200 out of which are endemic plants, not to be found in other parts of the world. One of the most biologically diverse nations globally, Greece’s mountains, mainland and islands create special balances of plant life. A number of microclimates due to the domestic topography – the Aegean islands, the country’s high mountains like Olympus, Parnassos and Taeyetos, the drought-prone southern land – contributes to the rich flora, consisting of plants that have evolved adaptations to grow in this unique environment.
The Greek flora diversity is probably best demonstrated through the example of the Acropolis ‘sacred’ rock which despite being an extremely harsh ‘plant’ environment, it hosts over 300 plants.
Centuries ago Greeks began to discover and explore the medicinal value of some of the native flora of the land, and explore their use in remedies. Mastiha tears are beads of clear resin formed in the Mastiha trees and dropped on the ground. They are gathered for their healing properties and used in traditional remedies.
Saffron is harvested by hand from the crocus flower by communities of growers in Northern Greece. With its complex bitter taste and exceptional medicinal applications,it is the most expensive spice in the world with a value equivalent to gold.
Species of native “mountain teas” that grow wild on the remote mountain terrain have proven antiinflammatory,antioxidant and antibacterial properties, and are sought after around the world.


We co-operate with
• micro farmers
• agricultural unions
• educational & social institutions
We teach our partners organic farming and sustainable agricultural systems, help them throughout all stages of cultivation and harvesting in association with the Agricultural University of Athens, and support them financially through purchasing their produce to be used in our formulations. We support solely organic farming through contractual agreements. We train and advise where necessary.

Working with instead of competing against

The choice not to cultivate ourselves the herbs that we need, is a conscious one. Our aim is not to compete, but to support the farmers and their unions, as well as the community bodies.

Micro Farmers

Ms Maria Komini, THESPROTIA
A co-ooperation with Ms Maria Komini, a farmer from Thesprotia. Ms Komini collects high quality self-sown aromatic plants, abiding to all the necessary procedures for the sustainability of the local flora. The sage collected, comes from the region of Faskomilia which is how sage is called in Greece.

Ms Goudroubi Vasiliki, LARISA

Ms Georgia Kleronomou, SAMOS
A co-operation with Ms Georgia Kleronomou, a farmer from the island of Samos. Due to its climate and soil, Samos is considered ideal for the cultivation of aromatic plants. Ms Kleronomou has been farming organic aromatic plants for years, while also operating an essential oil production unit. Our partnership with Ms Kleronomou does not confine only to the supply of Thyme and Artemisia, but extends to various organically farmed herbs that we use in our certified organic Materia Herba tea blends.

Agricultural Unions

A co-operation with the Chios Mastic Growers Association, which comprises of 4,500 families that reside on the island and cultivate this unique, indigenous product that plays a significantly active role in the economy of the island.

A co-operation developed to support over 1,500 families in 20 villages around the area of Kozani. These families grow and collect what is considered to be one of the best organic saffron varieties worldwide. Over 150,000 flowers are collected by hand to produce just over two pounds of saffron.

This co-operative has been formed by a group of local farmers who previously grew tobacco - once Greece’s most popular produce - yet due to the declining demand for the plant, were forced to abandon its farming. In search for an alternative source of income that could stimulate financially the region, these farmers have created an essential oil production unit and have started cultivating aromatic plants.

A co-operation with organic chestnut tree farmers, in the area of Achramites in Arcadia. After the devastating forest fires of 2007, growing chestnut trees is one of the very few agricultural activities that have survived in the area.



We extract and isolate the active ingredients of our selected plants, at our own environmentally friendly, certified herb extraction unit (ISO 14001 & ECOCERT certified), the outcome of an over five year-long effort. This, first in Greece, unit was created with the Pharmacy School of the University of Athens based on our homeopathy pharmacy heritage, our deep understanding of herbs, their properties and clinical benefits and innovative extraction methods. It enables us to extract and gently isolate active ingredients in order to produce premium quality, clinically effective organic extracts. A processed herb’s liquid extract can be condensed so that we can take both semi-liquid and dry extracts and isolate those to produce various active agent families in liquid, semi-liquid and dry form. We are also able to isolate the plant’s scent and essential oils. One single herb offers us up to 11 extracts and active agents that can be used independently or combined for greater efficacy. To avoid burdening the environment we have made the decision to use natural instead of chemical solvents despite the higher cost, while the extraction process residue is turned into organic soil and sent back to our network of organic farmers. A literally no-waste operation.
