Essential Oils – Guide to Aromatherapy

Aromatherapy has accompanied humanity for thousands of years. Ancient Egyptians used aromatic essences in embalming and mummification, Greeks and Romans added them to baths, and medieval healers prepared complex healing preparations from them. Today, aromatherapy is experiencing a well-deserved renaissance supported by modern research that confirms the demonstrable effects of essential oils on both physical and mental health. On pestik.cz you will find a carefully selected range of products for aromatherapy and essential oils from verified suppliers.

What are essential oils and how are they made?

Essential (ethereal) oils are highly concentrated, volatile aromatic compounds obtained from various plant parts – flowers, leaves, bark, roots, fruits, or resins. Although called "oils," they are not fatty – their base consists of dozens to hundreds of chemical compounds that together determine the characteristic scent and biological activity of each oil.

Production Methods

Steam distillation is the most widespread and oldest method. Water vapor passes through plant material, releases ethereal oils, and after condensation, the oil naturally separates from water. This method is used to obtain oils from lavender, rosemary, eucalyptus, and most aromatic herbs.

Cold pressing is used exclusively for citrus oils. The peels of oranges, lemons, grapefruits, and other citrus fruits are mechanically pressed and the oil is separated from fruit juice. The method preserves fresh, authentic aroma.

Solvent extraction is used for delicate flowers such as jasmine, rose, or tuberose, which would not survive steam distillation. The resulting product is labeled as absolute – it is exceptionally intense and resembles the flower's natural perfume.

CO2 extraction is the most modern method. Carbon dioxide under high pressure acts as a gentle solvent and produces pure extracts with the complete chemical profile of the plant, including compounds that would be lost in distillation.

Most Popular Essential Oils and Their Effects

Overview of Commonly Used Oils

Organic essential oils are certified products from organically grown plants, obtained without pesticides and synthetic fertilizers. They are a natural choice for anyone who values raw material purity and transparent origin.

How to Use Essential Oils – Application Methods

Essential oils are highly concentrated substances and in the vast majority of cases must not be applied to skin undiluted. Exceptions such as lavender or tea tree apply only to spot application on specific areas and not for extensive use. There are several proven application methods.

Aromatic Diffusion

The safest and most widespread method. Aroma diffusers disperse essential oils into the air in the form of fine mist. Ultrasonic diffusers work quietly and simultaneously humidify the air – they suit bedrooms and children's rooms. Nebulizing diffusers do not use water and spray pure oil, achieving higher intensity of aromatherapeutic effect, however, oil consumption is significantly higher.

Aroma lamps represent a traditional alternative. Add 3-5 drops of oil to a ceramic bowl with a little water and a candle heats the mixture from below. They are affordable, simple, and create a cozy atmosphere – ideal for living rooms or bathrooms.

Local Application

When applying to skin, essential oil must always be diluted in carrier oil. Recommended dilutions according to user group:

• Adults: 2-3% (12-18 drops of essential oil per 30 ml of carrier oil)
• Sensitive skin: 1% (6 drops per 30 ml)
• Children (6-12 years): 1% (6 drops per 30 ml)
• Pregnant women: 0.5-1% (3-6 drops per 30 ml), exclusively after consulting a doctor

Popular Carrier Oils

The choice of carrier oil affects not only the resulting effect, but also the feel on the skin and absorption rate:

• Jojoba oil – the most universal choice, absorbs without leaving a greasy film and has exceptionally long shelf life
• Almond oil – gentle and easily spreadable, ideal base for massage oils
• Coconut oil – naturally antimicrobial, excellent for hair, dry elbows, and heels
• Grape seed oil – light texture, well tolerated by oily and combination skin
• Argan oil – rich in vitamin E and fatty acids, suitable for mature and dry skin

Inhalation

Direct inhalation is the fastest method for acute needs. Simply apply 1-2 drops on a tissue or to your palms, bring to your nose, and breathe deeply several times. Steam inhalation (2-3 drops in a bowl of hot water, head covered with a towel) is particularly effective for colds, runny nose, and inflamed mucous membranes of the respiratory tract.

Bath

Add 5-10 drops of essential oil to warm bath water – but always pre-mixed with carrier oil, full-fat milk, or bath salt. Essential oils do not dissolve in water, and without an emulsifier, they would remain on the surface in concentrated form, which can irritate skin.

Synergistic Blends – The Art of Combining Oils

A properly assembled blend of essential oils can multiply the effect of individual components. These combinations are proven by practice and suitable for use in a diffuser as well as a base for massage oil:

Blend for Better Sleep

• 3 drops lavender
• 2 drops cedarwood
• 1 drop chamomile

Blend for Concentration and Mental Performance

• 3 drops rosemary
• 2 drops peppermint
• 1 drop lemon

Blend for Deep Relaxation

• 3 drops orange
• 2 drops ylang-ylang
• 1 drop frankincense

Blend for Cold and Runny Nose

• 3 drops eucalyptus
• 2 drops tea tree
• 1 drop peppermint

Safety Rules of Aromatherapy

Essential oils are powerful natural substances that require informed handling. Following basic rules prevents most adverse reactions:

• Never apply undiluted oils to skin – this applies even to oils marked as gentle
• We do not recommend internal use without professional supervision – consult exclusively with a qualified aromatherapist or doctor
• Store in dark glass bottles away from children and direct sunlight
• Perform a skin test before first use – apply diluted oil to the inner forearm and monitor the reaction for 24 hours
• Citrus oils are photosensitizing – after their application to skin, avoid direct sunlight for at least 12 hours
• During pregnancy and epilepsy – consulting a doctor is an obligation, not a recommendation
• Pets – especially cats lack the enzymes needed to metabolize many components of essential oils; always verify the safety of a specific oil before use in a household with cats or dogs

How to Choose Quality Essential Oil

The quality of essential oils on the market varies significantly and cannot be reliably assessed by price or attractive packaging. When selecting, focus on these indicators:

1. The Latin name of the plant must be stated on the label – for example Lavandula angustifolia, not just "lavender." Different species of the same genus may have different effects and safety profiles.
2. Country of origin speaks to terroir – climatic and soil conditions that directly influence the oil's chemical composition
3. Extraction method – steam distillation, cold pressing, or CO2 extraction affect the resulting chemical profile
4. Declared 100% purity – without synthetic additives, dilutants, or identical natural fragrances
5. Dark glass bottle – protects oil from oxidation caused by light and heat
6. Certifications and analyses – organic certificate or available GC/MS analysis (gas chromatography) confirm composition and authenticity

On pestik.cz you will find carefully selected essential oils and organic essential oils that meet strict quality criteria and whose origin is transparently documented.

Frequently Asked Questions About Essential Oils

How long does an essential oil last after opening?

Durability varies significantly depending on the type of oil. Citrus oils (lemon, orange, grapefruit) are the least stable and last approximately 1-2 years. Herbal and leaf oils such as lavender, eucalyptus, or tea tree retain quality for 3-5 years. Wood and resin oils – frankincense, cedarwood, or patchouli – are an exception: their profile harmonizes with age and shelf life exceeds 6-8 years. Always store in a dark, well-sealed bottle in a cool place.

Can essential oils replace medicines?

Essential oils are a valuable supplement, not a replacement for medical care. Aromatherapy demonstrably supports managing stress, insomnia, headaches, or minor skin problems. For more serious health problems, always consult a doctor and never discontinue prescribed medication based on aromatherapeutic practice.

Is it safe to use essential oils in the presence of small children?

For children under two years of age, we recommend exclusively diffusion in a well-ventilated space and only mild oils – lavender, chamomile, or mandarin. Perform local application to the skin of children under six years only after consultation with an aromatherapist or pediatrician, always in minimum dilution of 0.25-0.5%. Avoid eucalyptus and peppermint oils in children under three years, as they can irritate the respiratory tract.

What is the difference between essential oil and fragrance oil?

Essential oil is a natural product obtained directly from a plant, whose therapeutic effects stem from a complex mixture of hundreds of naturally occurring compounds. Fragrance (perfume) oil is a synthetic scent designed to imitate natural aroma – but without any biological activity. Fragrance oils may contain phthalates and other synthetic chemicals and are unsuitable for aromatherapeutic purposes. For aromatherapy, always choose exclusively pure, natural essential oils with documented origin.
