Differences Between Different Lavenders and Its Oil


Description

The quality of essential oils mainly depends on the variety, origin, extraction method and extraction part. Lavender oil is a very common essential oil we like to choose. How much do you know about it and lavender plants?

1543223053173881.jpgThere are mainly three species of lavenders, that is Lavandula angustifolia, Lavandula latifolia and lavandula hybrid. Lavandula angustifolia is often called true lavender, pure lavender or Alpine lavender. It is cold-tolerant and suitable for growing in the highlands between 800 and 1500 meters above sea level. The flowering period is from mid-July to late August.

True lavender is propagated through seeds. Each cluster of real lavender comes from a unique seed, and the genes of each seed are unique. In this way, we can see the main visual changes in lavender: the shape and color of the flower spikes (lavender to dark purple, sometimes pink or white).

The amount of real lavender is rare and the yield is low: every 150 kg of real lavender can only produce 1 kg or 1.1 liters of 0.88 true lavender essential oil. The production of essential oil per hectare is only about 15 to 20 kg.

True Lavender has a rich, subtle and balanced fragrance. It is mainly used for Aromatherapy. 100% pure natural lavender essential oil is applicable for the treatment and alleviation of the following symtoms: insomnia, headache, stress, dry eczema, sunburn,etc.

We can easily tell the differences between true lavender from high lavender from the height and stems. It can adapt to the hot and dry climate, as well as the chalky soil, which is most suitable for growing on the south slope above 500 meters above sea level.

Spain is an important producing area of high lavender. High lavender blooms between May and August, and its purple-blue flowers have a strong camphor flavor. High lavender oil is commonly used in oil-colored thinners and nail polish accelerators. It is rarely used in aromatherapy because of the large difference in essential oils in different regions.

Lavandula hybrid is a natural hybrid of true lavender and high lavender produced after pollination(especially bees). In 1930s, with the born of ground insertion technology, the planting area of lavendual hybid is rapidly growing. 

Compared with real lavender, its essential oil production is significantly higher: on average, it produces 150 kilograms of essential oil per hectare, which is 8 to 10 times higher than that of real lavender.

No matter which lavender as raw material of lavender essential oil, steam distillation is a popular way to extract lavender essential oil for beauty purpose. 

The extraction steps are as follows: (1) lavender dried flower weighing; (2) dried flowers are placed in water, the ratio of dry flower to water is 1:8-10; and (3) the soaked flowers are placed in the distiller; 4) steam distillation extraction: steam is injected into the above-mentioned soaked flower plant material, so that the soaked flower plant material is evaporated by heat, and the boiled gas is collected and cooled to obtain an extract; (5) secondary separation: because of incomplete separation, oil-water mixing may occur, and the oil may be separated twice in the oil-water separator to obtain the essential oil; (6) the pure essential oil obtained by the separation is weighed; (7) the pure essential oil is stored.                                

For better extracting effect, the choice of essential oil distiller is also very important. We suggest double-layer stainless steel lavender distillation equipment for you because of its less energy consumption, simple operation and expandable capacity.
