Now online shopping, such as a treasure, a cat, and a ning all have essential oils to sell, and offline shopping, such as some tourist markets, mostly in Yunnan, because essential oils first rose from there.

What is essential oil?

Take Yunhuayun essential oil as an example. Pure natural essential oil is a volatile aromatic substance extracted from flowers, leaves, stems, roots or fruits of plants by steam distillation, extrusion, cold soaking or solvent extraction. Essential oils are divided into diluted (compound essential oils) and undiluted (unilateral essential oils). Essential oils are highly volatile, and will evaporate quickly once they come into contact with air. For this reason, essential oils must be stored in sealable bottles, and once opened for use, the lid should be put back as soon as possible.

What is essential oil for?

According to the different extracts and preparation methods of essential oil, essential oil can be used for skin care, and can also be used for health preservation through specific massage techniques to achieve specific effects.

1. Air purification and sterilization: Because essential oil has antibacterial and antiseptic components, it has antibacterial, antimicrobial and antiviral properties.

Second, provide cellular nutrition: because essential oil contains hormones, vitamins and antibiotics, it can provide cellular nutrition for our body.

Third, balance the body and mind: the most important characteristic of essential oil is smell, which will affect the limbic system of the brain and act on the sense of smell. Tiny aromatic molecules will cause psychological and physiological reactions at different levels in the central nervous system.

Immune function: One of the most important characteristics is that aromatic essential oil helps to strengthen the body's immune system and help resist the attacks of various germs and viruses.

Fifth, it has natural anti-corrosion characteristics.

Brief introduction of essential oil

Essential oil Essential oil is a volatile aromatic substance extracted from flowers, leaves, stems, roots or fruits of plants by steam distillation, extrusion, cold soaking or solvent extraction. Essential oils are divided into diluted (compound essential oil) and undiluted (single essential oil). Essential oils are highly volatile, and will evaporate quickly once they come into contact with air. For this reason, essential oils must be stored in sealable bottles, and once opened for use, the lid should be put back as soon as possible.

Not all plants can produce essential oil, only plants containing balsam glands can produce essential oil. The distribution of balsam glands in different plants is different, and some are on petals, leaves, roots or trunks. After extracting the sachet, it becomes what we call "plant essential oil". Essential oils contain many different ingredients. Some essential oils, such as roses, can be made up of more than 250 different molecules. Essential oils are lipophilic and easily soluble in oils, because the molecular chain of essential oils is usually short, which makes them easily penetrate into the skin and enter the body through abundant capillaries under subcutaneous fat. Essential oil is composed of some very small molecules. These highly volatile substances can be absorbed by nasal mucosa and enter the body, sending messages directly to the brain, and regulating emotions and physical functions through the limbic system of the brain. Therefore, in aromatherapy, essential oil can strengthen physiological and psychological functions. Each plant essential oil has a chemical structure to determine its fragrance, color, fluidity and the way it works with the system, which also makes each plant essential oil have a set of special functional characteristics.

Essential oil is composed of terpenes, aldehydes, esters, alcohols and other chemical molecules. Because of its high fluidity, it is called "oil", but it is essentially different from the vegetable oil we see every day. The main components of vegetable oil are triglycerides and fatty acids.

Four grades of essential oil

Essential oils are divided into four grades:

The fourth grade (d): fragrant dew, pure dew or flower water; Level 3 (c): perfume level; Level 2 (b): food grade; Level 1 (a): pure essential oils

Fold the fourth stage (d)

Pure dew or flower water refers to a 100% saturated distilled stock solution separated from essential oil during distillation and extraction, which is natural, pure, gentle and skin-friendly.

Extraction method of pure dew-distillation method

Mixing petals of modern plants and distilled water in a certain proportion into a distiller, boiling on fire, and carrying out strong plant aromatic essential oil by using steam to form a steam state containing essential oil; After cooling process, it is condensed into liquid state by temperature difference, thus separating pure dew.

Fold the third stage (c)

Perfume-grade C-grade oil is the essence or perfume that perfume-grade oil is usually mixed with chemical solvents, and used to obtain high returns. Generally speaking, the concentration of perfume mainly has five grades, which are distinguished as follows:

Parfume: the concentration is above 20%

Eau de Parfume: the concentration is about 10-20%.

Eau de Toilette: the concentration is about 5- 12%.

Eau de Cologen: The concentration is only 3-6%.

Eau Fraiche: the concentration is only 1-2%.

Fold the second stage (b)

Food grade B essential oil is food grade and contains synthetic materials, pesticides, fertilizers, chemical/synthetic agents, or vehicle oil (base oil).

Fold the first stage (a)

Pure essential oils-Pure Essential OilA Grade A essential oil is pure medical grade quality (the highest grade), which is distilled by natural and organic plants with steam at a proper temperature.

Essential oil products are certified by gas chromatography (GC) and mass spectrometry (GC-Mass) with the highest quality standards in the industry, reaching or exceeding the certification standards of international standardization organizations (USDA NOP, ACO and BFA in Australia and IFOAM in the world).

Efficacy function

Essential oil can be composed of 50-500 different molecules. Under the arrangement of nature, these molecules coexist in perfect proportion, which makes each plant have its particularity, and therefore its mysterious effect on human body is extremely broad. essential oil

Essential oil can prevent infectious diseases, bacteria, viruses and molds, prevent inflammation and spasm, promote cell metabolism and cell regeneration, and make life better. Some essential oils can regulate endocrine organs, promote hormone secretion, and make the physiological and psychological activities of the human body develop well.

The well-known effect of essential oil of botanist is nothing more than the psychological effect of soothing and invigorating the spirit, but the effect of essential oil is not limited to this. Different kinds of essential oils also have different functions, and for some diseases, they also have the function of relieving and alleviating symptoms. Essential oil is very helpful for many diseases, and combined with drug treatment, it can make the disease recover faster. And used in daily life, it can purify the air, disinfect and sterilize, and prevent some infectious diseases at the same time.

Essential oil has a good curative effect on endocrine, metabolism, urinary system, sexually transmitted diseases, immune system, gynecological diseases, muscle and bone diseases, skin diseases, physical symptoms and diseases, nervous system and mental diseases, eye, ear, nose, oral cavity, dental diseases, respiratory diseases, blood circulation diseases and digestive system diseases.

Pure natural plant essential oils have the following main functions:

Respiratory system: plant essential oil molecules are absorbed by nasal mucosa system to stimulate olfactory nerve, which transmits stimulation to brain center, and the brain is excited. On the one hand, it dominates the nerve and plays a role in regulating nerve activity; On the other hand, it enters the alveoli through the respiratory system, and then enters the blood through blood circulation and is directly transported to all parts of the body.

Nervous system: it directly enters the skin through affinity. On the one hand, plant essential oil molecules stimulate nerves, and finally regulate nerve activity and internal circulation; On the other hand, it directly acts on the internal environment and other stable States, which accelerates the activity of body fluids, thus improving the internal environment and further regulating the whole body and mind.

Stimulating sympathetic and parasympathetic nerves, calming and hypnotizing, exciting and refreshing, adjusting mental state, resisting depression, relieving psychological pressure and repairing nervous system;

Metabolic system: through affinity, plant essential oil molecules can quickly improve the living environment of local tissues and cells, accelerate their metabolism, and comprehensively solve some problems caused by local metabolic disorders.

Promote exchange: through affinity, plant essential oil molecules enter subcutaneous tissue, and then enter blood and lymph through body fluid exchange, which promotes blood and lymph circulation and accelerates human metabolism.

Olfactory nerve

The smell is fragrant, and the natural fragrance can stimulate the front lobe of the brain to secrete two hormones, endorphins and enkephalins, so that the spirit is in the most comfortable state, which is the best way to protect the soul. Moreover, different essential oils can be combined with each other to prepare their favorite fragrance, which will not destroy the characteristics of essential oils, but make the functions of essential oils more powerful.

therapeutic action

★ Lavender oil: It has the functions of calming, promoting bile secretion, healing, diuresis, dredging menstruation, hypnosis, lowering blood pressure, sweating, etc., and its fragrance is excellent, "like perfume". It is a highly respected natural essential oil at present. It is mainly produced in France, and then transplanted from the Mediterranean Alps to all parts of the world. Now it is cultivated in Italy and Russia, and there are also bases in Yunnan, Xinjiang and Shaanxi, with good quality.

★ Rosemary oil: It has the functions of relieving cough, expelling wind, treating hypotension and invigorating stomach, and also has the functions of promoting bile secretion, diuresis, dredging menstruation and sweating. Its cool and pungent herbal aroma, some of which are like lavender, eucalyptus leaves, camphor and nutmeg oil, gives people a refreshing feeling, and the aroma is strong, penetrating and long. Europeans prefer it. It originated in Mediterranean countries. In China, it was only cultivated sporadically in flower beds around the country. At present, several places are preparing to expand the planting area and open bases.

★ Lemon oil: it has the functions of expelling wind, cleaning, diuresis, relieving fever, promoting blood circulation, stopping bleeding, lowering blood pressure and cooling. It originated in China or India and spread to Europe and Mediterranean countries. Now it has a large output in Italy, the United States, Cyprus, Spain, Brazil, Guinea and other countries. The quality of cold pressed oil produced in Sichuan is very good, and a small amount is also produced in Yunnan and Guangxi. It should be noted that lemon oil and fragrant lemon oil are different in aroma and curative effect, so don't confuse them.

★ Lemon oil: At present, it is only known to have sedative effect, so it is not taken seriously.

★ Clove oil: It also has the functions of expelling wind, healing and invigorating stomach, and has a good aroma. Mainly produced in Madagascar, Tanzania, Penang, Malaysia, Moluccas, India and other places, China has also introduced and produced a small amount of clove oil, which can be divided into bud oil, leaf oil, stem oil and purified oil (extracted from clove bud extract), bud oil, leaf oil, stem oil and purified oil (extracted from clove bud extract), and bud oil and purified oil have better curative effects.

★ Peppermint oil: it has the functions of expelling wind, dredging menstruation and invigorating stomach. China produces Asian peppermint oil, while the United States and Europe produce pepper-like peppermint oil, the latter has a good aroma, sweet and beautiful, but the curative effect is similar.

★ Cinnamon oil: It has the functions of dredging menstruation, stopping bleeding and invigorating stomach. It is produced in Guangdong and Guangxi, and is one of the famous essential oils exported earlier in China. "Shen Nong Ben Cao Jing" listed cinnamon as the top medicine. Cinnamon oil is fragrant, warm and sweet, and is deeply loved by people in Europe and America. However, Asians feel that it is "too strong" and is rarely used for bathing.

★ Thyme oil: It has the functions of expelling wind, promoting bile secretion, promoting diuresis, dredging menstruation, removing phlegm, treating hypotension, invigorating stomach and sweating.

Distinguish between true and false

Look at the price

Plant essential oil is mainly extracted by distillation. Generally, 2-3 kilograms of essential oil can be extracted from 100 kilograms of flowers and plants, so the price of real essential oil will not be too cheap. The market reference price is: common essential oil such as yunhuayun tea tree oil is about 10m/300-900 yuan, and rare essential oil such as sandalwood is about10m/900-/kl. I suggest you go to a regular large shopping mall or Tmall flagship store to buy. If some self-proclaimed imported essential oils are cheaper than domestic products, their authenticity is self-evident.

See usage

Except for a few varieties such as roses, tea trees and lavender, most pure essential oils can't be used directly on the skin, otherwise it will cause burns and peeling. If the essential oil introduced to you by the merchant says that it can be used directly on the skin, it is said that it is pure essential oils, so there is a problem. We must distinguish the difference between base oil and essential oil. Some base oils in the name of essential oil have indeed deceived many people.

Smell

Most pure essential oils tastes soft and mellow, because it is 100% extracted from plants, so pure essential oil has an indescribable taste of natural plants (although the smell is not necessarily good), and the essential oil blended with essence has a slightly pungent taste, so long-term use of such essential oil is harmful and not beneficial. When you first enter the nose, the taste is not very strong, but it has a aftertaste. When you get to the back of your head, you will have a feeling of wilderness. Everyone feels different about him, and its front, middle and back flavors are different.

Dianxun

A. If oily residue (different from scale) is left after the unilateral essential oil is smoked several times, it means that it has been diluted with vegetable oil or mineral oil; If crystals remain, they are probably diluted with ethanol and ether, which is self-evident.

B, take a glass of clear water and drop a drop of essential oil. The real pure essential oils generally volatilizes faster, and there is no residue after that. If it is diluted with vegetable oil or mineral oil, the volatilization speed will be much slower, and oil stains will often be left on the water surface.

Look at the packaging

Essential oils are usually stored in dark sealed small glass bottles, with special caps resistant to strong acids and alkalis to prevent sunlight and oxygen from infiltrating, so that essential oils are not volatile and deteriorate. In a good preservation environment (at room temperature), it can usually be preserved for two years, and the essential oil with good quality can be preserved for 4-5 years. Citrus essential oils can also be stored for 1-2 years, and the products packed in bottles equipped with drippers are generally diluted essential oils between 3%- 10%, not pure essential oils. The label of pure plant essential oil should indicate the purity.

Look at specific gravity

Generally speaking, the proportion of grass essential oil is the lightest, and it will disperse quickly when dropped into a glass of water, and the water surface will be in an oily state; Resin essential oil is the heaviest molecule. If it is dripped into a glass of water, it can fall into the bottom of the cup completely and should not be dissolved in water. But both of them will be under the water surface, and two kinds of essential oil molecules will be distributed. Although they are insoluble, they have not yet permeated the whole glass of water. Citrus, a special flower essential oil, is heavier than water and insoluble in water. Similar to resin essential oil, it will drop straight into the bottom of the water, and crystal clear dark green essential oil beads can be seen.

Look at the color

For example, German foreign citrus contains a very precious ingredient "Blue Sutra", which is dark blue in color and has a strong medicinal flavor. If what you bought is colorless, you must have been cheated!

Look at the texture

The purer the quality of essential oil, the stronger the permeability. Rub the tested essential oil lightly on the back of your hand or the inside of your wrist, and then massage with your fingertips a few times. Good quality essential oil will be absorbed in an instant and will not leave shiny oil components on the skin. You can also observe whether the essential oil contains impurities. For example, the essential oil pressed from the peel by the traditional freeze pressing method will leave a little residue, which will make the product quality poor. Because of the molecular structure, the volatile speed of the essential oil is relatively fast, and it is played within 5- 10 minutes, which shows that it is relatively pure. Volatile slowly and not necessarily pure essential oil.

Look at the degree of fusion

Pure essential oil is very lipophilic, and when it is mixed in base oil, it will be completely integrated and the molecules of the two will be completely combined. Otherwise, the essential oil contains chemical synthesis or wax, so that it cannot be fully integrated with the base oil.

Look at the place of origin

Plants that extract essential oils will have different qualities due to different places of origin. The quality of land, temperature, humidity, planting level, harvest time and treatment methods all directly affect the quality of its essential oil. Therefore, attention should be paid to the origin of the plant when choosing essential oil. At present, the relatively good producing areas in China are all in Yunnan. It is recommended to buy famous brands in Yunnan to buy essential oils.

Common flavor types

Usage daquan

Plant essential oils are known as "plant hormones". In fact, many essential oils are similar in nature to human hormones and play an important role in human body. Generally speaking, the use of essential oil is as follows:

1 massage

Massage is one of the most effective ways to use it, and it is also the most common way to use essential oil. Because of the high concentration of pure essential oils, it can't be directly used for massage, so it must be mixed with base oil before massage. The proportion of general body massage is 2.5%, that is, the proportion of adding 25 drops of pure essential oils to 50ml of base oil; Generally, the proportion of facial massage oil is 1%, and 50ml of base oil is added 12 drops of pure essential oils. Caution: Essential oil skin test is required before sensitive skin is used.

2, bubble bath

Bubble bath is a method with quick curative effect. Simple bubble bath has many benefits to the body, and it is more helpful to promote blood circulation, enhance vascular elasticity, regulate body function and so on with essential oil. We can choose 1 one or several kinds of favorite essential oils, and the total amount should not exceed 8 drops. It is best to dilute it with pure milk first, then pour it into the bathtub and soak for 10- 15 minutes.

3, aromatherapy

We can usually buy an aromatherapy stove, an aromatherapy lamp, an aromatherapy stone, an aromatherapy instrument, etc. for aromatherapy use. To use an aromatherapy stove, we need to buy an odorless and smokeless candle. You can also drip the essential oil 1 2 on the facial tissue, and the essential oil will slowly give off a pleasant taste. It is best not to drop essential oil into the humidifier, which is not good for the humidifier and essential oil.

4. Blend with skin care products such as creams and lotions.

It is best to choose pure plant-based creams and lotions without fragrance. Just add 10 drop of pure essential oils to 50ml of creams or lotions, for example, Hancuixuan's Rose Moisturizing White Cream, Hamamelis Convergence and Firming Essence Cream, etc. This fragrance-free emulsion can be purchased from reputable essential oil merchants such as Hancuixuan and Tianyuan Wusha.

5, cold, hot compress

Add 5 or 6 drops of pure essential oils to 1L hot water or cold water, stir well, soak the clean towel and apply it to the required part. Hot compress can clean pores and relieve pain, while cold compress is mainly aimed at cooling, sunburn and swelling.

6, inhalation method

You can directly drop the essential oil 1 drop into the palm of your hand, rub your hands together, then cover it around your nose and take a deep breath. Usually this method is only for lavender essential oil and tea tree essential oil.

7, steam evaporation method

Add boiling water to a glass, ceramic and stainless steel (non-plastic) bowl, drop 2 or 3 drops of pure essential oils, put your face close to the bowl mouth and take a deep breath for 3 or 5 minutes. It is best to cover your head with a big towel to prevent steam loss.

In the process of using essential oil, it is necessary to pay attention not to use it too often. If you want to achieve curative effect, you usually need a low dose and last for a period of time, so the effect of conditioning your body function is the best. Usually used, the concentration is still 35%; For more dangerous essential oils, the content shall not exceed 3%.

Photosensitive essential oils should not be used in places where the sun will shine. Some essential oils contain components that can cause light sensitivity. If exposed to the sun after use, the skin will turn black and even cause skin cancer. Photosensitivity can also be divided into light and heavy, such as grapefruit. It doesn't matter if you use it in low dose at night and get in the sun the next day. But citrus essential oils, such as lemon, bergamot, orange and sweet orange, are all photosensitive essential oils. And the concentration of essential oil is extremely high, so do not touch eyes. The oral administration of essential oils must be explained by experts or manufacturers. Essential oils with good quality can be taken orally, but not all essential oils can be taken orally, and the essential oils in the workshop are mixed. If it is impossible to judge the quality of essential oils, it is best not to take them orally.

When there is a wound on the skin, essential oil should be avoided, but if it is a small knife wound or a small wound, essential oil can be used to make the skin heal quickly. Do a skin test before use, adjust the concentration of 3% essential oil first, and use it under the armpit or chest until there is no allergic phenomenon for at least 24 hours before using the essential oil. Except lavender and tea tree essential oils, which can be used on the skin as pure essential oils, other essential oils must be diluted with base oil before they can be used on the skin.

Do not use the same essential oil continuously for more than 3 weeks, and avoid using single essential oil every day. Under the intersection, the use of compound essential oil will be better than that of single one. If it is for conditioning, it can be used continuously for 3 months, and the longest is not more than half a year.

matters need attention

1, in the first few months of pregnancy and children, it is best to avoid using essential oils for massage or bathing.

2, skin or physical sensitive person, please sensitive test before use.

3. Except a few essential oils, such as lavender and tea tree, which can be directly applied to the skin, most other essential oils must be diluted or blended with base oil before use, unless there are other special suggestions.

4. Do not expose yourself to the sun within four hours after using citrus essential oils (such as bergamot and lemon) on your skin.

5. Essential oils cannot replace drugs. Therefore, if the symptoms do not improve after use, please be sure to see a doctor, and never give up the medicine you have already used because of the use of essential oil.

6. Patients with hypertension, hypotension, epilepsy, neurological and renal diseases should use it carefully. It is best to consult an aromatherapist before using it.

7. Please use the recommended amount. Excessive use will lead to counterproductive, and even cause excessive burden on the body.

8, please avoid direct contact with children, so as to avoid misuse and danger.

9. Avoid containers with plastic, soluble or oil-colored surfaces, and use glass, stainless steel or ceramics when diluting essential oils.

10, it is best not to take the essential oil orally unless instructed by an aromatherapist or doctor.
