Route of exposure and dose
The absorption by the body of the active compounds present in essential oils can be provided in several ways. The choice of the optimum route will depend on the area that is to be treated and the efficacy / toxicity or selected essential oils (see composition and toxicity section). In particular, account must be taken of the fact that the toxic effect of the essential oils will depend significantly from the chosen route of absorption. The toxic effect of the essential oils will decrease in effect according to the following series of different routes of absorption (++++ high toxicity -> +: slightly marked toxic effect):
ocular: forbidden <Oral: ++++ <path atrial +++ = nasal +++ <airway ++ = channel uterine ++ <dermal
This is generally one of the most difficult routes of absorption because it can lead in some cases to overdoses and poisoning more or less severe, depending on the age of the person, the type of essential oils and absorbed constitution of the person. It must be used only on the advice of an experienced therapist.
This method of absorption is used in cases of acute infection treatment with doses of about 50 mg = 2-3 drops / 3 - 4x / d.
The possibilities are numerous oral absorption, mixed in a syrup, grape sugar in an in honey in a vegetable oil, etc. .. for direct absorption (via the digestive tract), or in admixture with a inert carrier in a capsule.
This absorption technique is also very delicate, because overdose is more risky than aborption this technique is extremely fast and allows you to transfer quickly and with a very good yield pure active principle in the general circulatory system allowing direct action in infected or inflamed areas located in the ventral area. It must also be applied on the advice of an experienced therapist.
The application rates are of the order of 150 mg for adults (40 to 80 mg for very young children).
The essential oils are absorbed in this case mixed with a wax-like carrier (such as Witepsol = semisynthetic glycerol) formed in a suppository using a suitable accessory.
- For vaginal:
The same principles as for absorption rectally apply in this case. But !! attention to the essential base phenolics oils are not recommended vaginally, because of their very high dermocaustic activity (eg, Winter savory (Satureja montana), rich in carvacrol).
- By percutaneously:
The percutaneous route is a good way to absorb essential oils (EO), which can be:
* Associated with vegetable oil (oil or macadamia nut because of highly absorbent) in amounts between 5 and 80% (20% max. Dermocaustic for compounds such as cassia, the Winter savory or cloves )
* Pure in the case of acute illness (beware of phenolic compounds present in the HE type Sarriettes Mountain Thyme thymol, Clove, etc ..., and aldehyde compounds: cinnamaldehyde present in the Cinnamon China because both are irritating to the skin or mucous membranes)
Integrated in a gel or cream in a proportion of between 3 and 8% *
- By inhalation:
This route of absorption is very often used in case of problems with the upper respiratory tract (sinusitis, colds, cough, fat, etc ...) and can be applied in a concentrated mixed with water vapor as c is the case of inhalations. However, depends on the essential oils used, the duration of a treatment session should not exceed more than 5 to 15 minutes.
