1. Therapeutic Use


TTherapeutic use
See the Healing sets for an overview of the protocols.

Humans have seven senses (not the five common senses). These senses are:

  1. Touch
  2. Smell
  3. Hearing
  4. Taste
  5. Eyes
  6. Skin (reaction of the skin without touching)
  7. Organs

The sense of smell is the only sense that has not fallen, is not under the influence of our past and our experiences. The therapeutic protocols make use of the fragrance, in addition to the frequency of the oil. Click here for an overview of all available healing sets (protocols).

2. External use


EExternal use
As perfume, deodorant, bath, etc.


UNormal skin
Can be applied undiluted to the skin
SSensitive skin
With sensitive skin first dilute with another pure vegetable oil
DSkin independent
Before use, dilute with other pure vegetable oil
In soap and shower gel

3-5% essential oil can be used in soaps and shower gels, which are rinsed off again.

Massage or skin oils

Essential oils dissolve very well in vegetable oils. The final mixture must be smooth to ensure that the dissolving/mixing is successful. Small drops of pure essential oil floating in the vegetable oil can irritate the skin. The correct dilution for massage oil is very important because a large skin surface comes into direct contact with the essential oil. Often 1% essential oil is used in massage oil. A suitable amount is 20 drops (±1ml/0.034oz) of essential oil to 100ml/3.38oz vegetable oil. If in doubt or if sensitive skin, it is better to first test for allergic reactions on a small area of sensitive skin. An example would be the knee cavity. Essential oils made from herbs/spices generally cause more skin problems than those of flowers and woods.

In ointments or creams

A 5% to 15% concentration of essential oils is used in ointments or creams. It usually is a little less for a facial cream and can rise to 15% for a healing ointment. It is important that the essential oil is mixed well in the ointment or cream. If the essential oil is not mixed with the ointment, small drops of pure essential oil may be present, which may irritate the skin. Always follow the instructions and the essential oil concentration, which is provided in the instructions. If in doubt, always use less, not more.

In the bath

(Essential) oils do not mix with, and float, on water. A few drop in bath water results with oil floating on the water surface. Consequently, direct contact with skin may cause skin irritation. It is recommended that essential oil is made soluble in water with an emulsifier*. For example, a small amount of (bath) salt, neutral bath foam, shampoo or honey. Add this mixture with the essential oil directly to the water when filling the bath. The oil is mixed with the water to deliver a relaxing or invigorating bath.
* a substance that aids in the mixing of two substances which are normally not or difficult to mix.

WARNING: Pure essential oils can damage plastic baths.
On the skin

Pure essential oils can irritate the skin. Some, like tea tree oil and lavender oil, can be used undiluted on pimples. Using essential oil this way is only recommended if the user has experience of essential oil and is assured of 100% pure organic essential oils. Tea tree oil is both anti-bacterial and fungicidal, but excessive use in pure form may also affect healthy skin. In the event this occurs it is important not to touch the adjacent healthy/normal skin with pure oil. The Fragrance Alchemy oils are safe to use on the skin. To date, there are on two mild occasions with Jasmine oil where irritation (red skin patches) have occurred after use.

3. Aromatic use


AAromatic use
Spraying, evaporation, etc.
Aroma diffuser

Essential oils may have harmful effects when used incorrectly. When small droplets (mist) have not completely evaporated and then inhaled, they migrate to the lungs, resulting in a possible chemical reaction. When using aroma diffusers it is recommended to avoid inhaling the visible mist and to avoid contact with the eyes. Specifically, in cold areas it may take longer for the mist to evaporate. However, when the aroma diffuser is place at some distance, the droplets in the mist can evaporate sufficiently before the “fragrance” is inhaled. This way, evaporation in an aroma lamp, can be a very effective way to enjoy the therapeutic benefits of essential oil.


When evaporating essential oils in an oil burner, with fragrance sticks, aroma stone, and potpourri or on a tissue, the airborne concentration is not excessive. Always use just a few drops. If the mucous membranes or eyes become irritated, too much has been used. It is recommended to use a smaller amount of oil in confined spaces.

4. Internal use


IInternal use
Flavoring agent, food supplement, etc.
Cooking with essential oils

The self-use of essential oils in food and drinks is possible when appropriate care is observed. A mistake in the correct dosage (i.e., using too much) or where the essential oil is not properly dissolved/mixed, may cause damage to the digestive system or organs. A suitable essential oil, appropriate experience and an approved recipe is necessary for a safe outcome.

The oils offered by Geuren Alchemie are, unless specifically stated, NOT intended or suitable for internal use.

Applications in which essential oils are to be used with caution

Take care with small children

The greatest danger/risk with most essential oils is when ingested. They can be coughed up by the corrosive effect of the oesophagus. This can cause the essential oil to filter into the lungs, potentially causing chemical inflammation of the lungs. This can have a fatal outcome. It is recommended to keep essential out of the reach of children. Most preferably, stored in a secure cabinet. Never leave used bottles in a location accessible by children.

Pregnancy and breast feeding

During pregnancy and breast feeding it is recommenced to avoid using certain types of essential oil. In the event of spillage, these oils can migrate from the skin into the bloodstream. At present the risks related to this are unknown. Additionally, strong concentrations of fragrances (including perfumes, etc.) should be avoided.


Whilst many essential oils are useful, enjoyable and sometimes even beneficial for humans, these can be toxic for pets. It is strongly recommended that users satisfy themselves with any potential side effects before using essential oils on animals.
