The invention of steam distillation contributed significantly to the development of perfumery, in perfecting the extraction of fragrances. The steam distillation technology significantly influenced Western perfumery and scientific developments, particularly chemistry.
Steam distillation is a special type of distillation (a separation process) for temperature sensitive materials like natural aromatic compounds.
Many organic compounds tend to decompose at high sustained temperatures. Separation by normal distillation would then not be an option, so water or steam is introduced into the distillation apparatus. By adding water or steam, the boiling points of the compounds are depressed, allowing them to evaporate at lower temperatures, preferably below the temperatures at which the deterioration of the material becomes appreciable. If the substances to be distilled are very sensitive to heat, steam distillation can also be combined with vacuum distillation. After distillation the vapors are condensed as usual, usually yielding a two-phase system of water and the organic compounds, allowing for simple separation.
When a mixture of two practically immiscible liquids is heated while being agitated to expose the surfaces of both the liquids to the vapor phase, each constituent independently exerts its own vapor pressure as a function of temperature as if the other constituent were not present. Consequently, the vapor pressure of the whole system increases. Boiling begins when the sum of the partial pressures of the two immiscible liquids just exceeds the atmospheric pressure (approximately 101 kPa at sea level). In this way, many organic compounds insoluble in water can be purified at a temperature well below the point at which decomposition occurs.

DIslanD Essential oils & hydrosols
The hellenic essential oils & hydrosols are genuine and authentic, and are distilled at the lowest possible temperature so as to ensure their optimal quality. We only use small inox stills (125 and 250 litres) which we supervise personally during the whole distillation process, having thus the privilege of watching every single drop as it comes out of the condenser!

There is a relationship between a culture and its plant environment, within which the herbalist plays a pivotal role. Herbalism is more than knowledge about healing plants, it is the experience and wisdom that comes from the relationship between humanity and plants. 
The natural environment   of Greece  famous worldwide for the beautiful islands,  is hiding a real treasure. The huge variety plant wealth, which Greece has. The group of ACHS college invited us to discover the tools of herbal medicine. The correct timing and the method gathering herbs, the use of the plants, distillation & essential oil production is very important knowledge for the Herbalist

Essential oil steam distillation
Steam distillation was invented by the Persian chemist , Ibn Sina (known as Avicenna in the West), in the early 11th century. He invented it for the purpose of extracting essential oils, which is used in aromatherapy and the drinking and perfumery industries.
Two amazing episodes inspired from a Mantinada
(madinada or patinada or kotsaki poem is composed of two verses that are usually fifteen syllables to rime or four lyrics not necessarily in rhyme)
SARANTAVOTANO (Fourty herbs) presents 40 medicinal plants with their lokal names and ends like that:
If you make  baths with all  those herbs your body remains painless and passionless
