→Properties of essential oils
The quality of plants is important too. A ravintsara from India holds less active ingredients than a ravintsara from Madagascar.
Another advantage is the environment. "The exceptionally rich and diverse terroirs of this island do not face pollution as in industrialised countries", remarked cardiologist [[Lionel Michat]]a french manufacturer, whose who use Malagasy essential oils are sold in his products in Europe under the '''''Les Aromagies''''' brand. And producers do not use chemical fertilisers either. These factors ensure the properties of plants to be 100% natural.
The cultivation of plants in Madagascar cannot be compared with many other countries. Whilst elsewhere trees of a single species are aligned in a field, in Madagascar a wild environment is kept where ravintsara grows next to ''[[Eucalyptus globulus]]'' but also next to plants and non-aromatic trees.
'''The essential oils of Homeopharma'''
This wild environment ensures the quality of the soil, assured Jean-Claude Ratsimivony, the founder .The essential oils of Homeopharma,their essential oils are tested and guaranteed in their laboratory to be of the highest quality.
Without the wild environment, the synergy between species would be lost. Plants need to breathe and sense. We must listen to Jean Claude, the modest grandson of a medical doctor and depository of remedies collected by his grandfather from traditional healers, who will tell you about the plants, their sensitivity, their stress before a cyclone. Resting time, which allows the plants to regenerate between pickings, is also respected and can reach up to four years depending on the species! Harvesting of plant organs is done in jute or cotton bags to prevent maceration. Partial drying is necessary in case of rain in order to reduce the amount of water contained in the plant. And if so, only one type of plant will be dried at the time to avoid contamination and ensure the right balance of chemical properties.
In short, the plants are treated for the treasures they are. And it doesn't stop there! Distillation over a wood fire, most of the time, is another added value to the Malagasy essential oils. In other countries it is done with regular gas heat. But firewood allows a variation of temperature which leads to a more complete extraction. The large molecules of the plants do not extract at a constant temperature if using gas. To be convinced of the importance of this, one needs only to observe the technicians at the Homeopharma distillery in [[Amparihy, Vontovorona]]. Their work procedure involves adding a piece of wood to light the fire and thereafter removing it to reach the desired temperature, causing a gradual temperature change.
